Fenestration
Dehiscence: lack of cortical bone at the level of dental root, at least 4mm apical to the margin of interproximal bone, the measurement was per found by graduated probe.
Or: lowering the crestal bone margin to expose root surface.
Fenestration: localized defect in the alveolar bone that exposed the root surface usually the apical or the medium third but did not involve the alveolar margin.
Or: is isolated areas in which the root is denuded of bone and the root surface is covered only by periosteum and overlying gingiva.
Fenestration is a term derived from Latin ward fenestra, meaning window, describe area of alveolar process devoid of bone, creating a window exposing the root surface.

Non surgical management of gingival recession- Dr Harshavardhan PatwalDr Harshavardhan Patwal
Treatment of gingival recession has become an important therapeutic issue due to the increasing number of cosmetic requests from patients. The dual goals of mucogingival treatment include complete root coverage, up to the cemento-enamel junction, and blending of tissue color between the treated area and non-treated adjacent tissues. Even though the connective tissue graft is commonly considered the “gold standard” for treatment of recession defects, it may not always be the best surgical option for every case. Dr Harshavardhan Patwal , Under non-experimental conditions, all root coverage procedures may be effective in terms of complete root coverage and excellent esthetics. Careful analyses of patient- and defect-related factors, however, are key considerations prior to selecting an appropriate surgical technique.
Indian Dental Academy: will be one of the most relevant and exciting training center with best faculty and flexible training programs for dental professionals who wish to advance in their dental practice,Offers certified courses in Dental implants,Orthodontics,Endodontics,Cosmetic Dentistry, Prosthetic Dentistry, Periodontics and General Dentistry.
mucogingival surgery or plastic surgery of muco-gingival tissue is a surgical procedure targeted to correct and eliminate anatomic, developmental and traumatic alterations of gingiva.
Periodontics is a specialized field of dentistry that focuses on the diagnosis, treatment, and prevention of diseases that affect the gums and other supporting structures of the teeth. It plays a crucial role in maintaining overall oral health and is essential for preserving the function and aesthetics of the smile. From gum disease treatment to dental implants, periodontics encompasses a wide range of procedures and practices aimed at ensuring the health and vitality of the oral cavity. As technology continues to advance, the integration of artificial intelligence (AI) has opened up new possibilities and avenues for innovation within the field of periodontics.
Periodontal diseases have afflicted humans since the dawn of his tory. Oral hygiene is practiced since ancient times. Sushruta Samhita contains numerous descriptions of severe periodontal disease with loose teeth and purulent discharge from gingiva. Our understanding of the causes of periodontal disease have changed greatly over time. The past inabilities of generalists to pinpoint systemic causes are being overcome with the application of modern epidemiologic and clinical research approaches.
The emerging science of nanotechnology, especially within the dental and medical fields, sparked a research interest in their potential applications and benefits in comparison to conventional materials used. Therefore, a better understanding of the science behind nanotechnology is essential to appreciate how these materials can be utilized in our daily practice. Nanotechnology is the research and development of materials, devices and systems exhibiting physical, chemical and biological properties that are different from those on a large scale. Nanotechnology offers a broad range of innovations and improvement in prevention, diagnostics, and treatment of oral diseases. Periodontal disease is one of the major dental illnesses that affect millions of people around the globe. It is estimated that 90% of the world population suffers from the disease. Recent nanotechnology advancement and innovations through Nano dentistry are increasingly providing a suitable solution for the treatment of many dental disorders including periodontal disease. This review aimed to provide an overview of the role of nanotechnology in periodontics and to evaluate its applicability in prevention and treatment of oral diseases and also to provide important recent updates on the various nanotechnology-based approaches for periodontal disease therapy.
Dental indices can be considered as the main tool of epidemiological studies in dental diseases, to find out the incidence, prevalence and severity of the diseases, based on which preventive programmes are adopted for their control and prevention.
When the body is under stress, it produces more of the hormone cortisol, which acts as an anti-inflammatory agent. When cortisol is produced peripherally in the gums, it stimulates mast cells to produce more proteins, simultaneously increasing inflammation and the progression of periodontal disease.
Aggressive periodontitis is distinguished from chronic periodontitis with respect to,
Age of onset
Rapid rate of disease progression
Nature & composition of the associated subgingival micro flora
Alterations in the host’s immune response
Familial aggregation of the disease
Types of Aggressive Periodontitis
Localized Aggressive Periodontitis-LAP
Generalized Aggressive Periodontitis-GAP
Localized aggressive periodontitis
Historical background,
Diffuse atrophy of the alveolar bone (Gottlieb-1923)
Deep cementopathia (Gottlieb-1928)
Parodontitis marginalis progressiva(Wannenmacher- 1938)
Periodontosis (world workshop in periodontics -1966)
Juvenile periodontitis (Chaput etal-1971)
Localized Juvenile periodontitis (world workshop in periodontics- 1989)
Localized aggressive periodontitis (International workshop by american academy of periodontology – 1999)
Clinical characteristics LAP
LAP is localized to first molar or incisor with interproximal attachment loss on at least two permanent teeth ,one of which is a first molar & involving no more than two teeth other than first molars & incisors.
Possible reasons for limitation of the destruction
After initial colonization of the first permanent teeth( first molars & incisors) Aa evades the host defenses by different mechanisms they are –
-PMN chemotaxis inhibiting factors
-Endotoxin
-Collagenases
-Leukotoxin
After this initial attack adequate immune defenses are stimulated to produce opsonic antibodies to enhance the clearance & phagocytosis of invading bacteria & neutralize leukotoxic activity there by colonization of other sites may be prevented
Bacteria antagonistic to Aa may colonize the periodontal tissues & inhibit Aa from further colonization of periodontal sites in the mouth ,hence Aa infection & tissue destruction is localized
Aa may lose its leukotoxin producing ability for unknown reasons
A defect in cementum formation may be responsible for the localization of the lesions
Clinical features of LAP
Age of onset –puberty & around 20 years of age
It affects both male & female
There will be a lack of clinical inflammation despite the presence of deep periodontal pockets & advanced bone loss
The amount of plaque is minimal & is rarely mineralizes to calculus
Plaque Contains elevated levels of Aa & Pg
The Rate of boneloss is about 3 to 4 times faster than in chronic periodontitis
Clinical features of LAP
Distolabial migration of the maxillary incisors with concomitant diastema formation
Increasing mobility of the maxillary & mandibular incisors & first molars
Sensitivity of denuded root surfaces to thermal & tactile stimuli
Deep dull radiating pain during mastication
Robust antibody response to pathogens
Radiographs reveal ‘arc shaped loss of alveolar bone extending from distal surface of the second premolar to the mesial surface of the second molar’
Localized Aggressive periodontitis
Generalized Aggressive Periodontitis
NON SURGICAL PERIODONTAL INSTRUMENT has been designed for specific purposes such as diagnosing the periodontal disease, removing calculus, planning root surfaces, curetting the gingiva and removing diseased tissue.
New Directions in Targeted Therapeutic Approaches for Older Adults With Mantl...i3 Health
i3 Health is pleased to make the speaker slides from this activity available for use as a non-accredited self-study or teaching resource.
This slide deck presented by Dr. Kami Maddocks, Professor-Clinical in the Division of Hematology and
Associate Division Director for Ambulatory Operations
The Ohio State University Comprehensive Cancer Center, will provide insight into new directions in targeted therapeutic approaches for older adults with mantle cell lymphoma.
STATEMENT OF NEED
Mantle cell lymphoma (MCL) is a rare, aggressive B-cell non-Hodgkin lymphoma (NHL) accounting for 5% to 7% of all lymphomas. Its prognosis ranges from indolent disease that does not require treatment for years to very aggressive disease, which is associated with poor survival (Silkenstedt et al, 2021). Typically, MCL is diagnosed at advanced stage and in older patients who cannot tolerate intensive therapy (NCCN, 2022). Although recent advances have slightly increased remission rates, recurrence and relapse remain very common, leading to a median overall survival between 3 and 6 years (LLS, 2021). Though there are several effective options, progress is still needed towards establishing an accepted frontline approach for MCL (Castellino et al, 2022). Treatment selection and management of MCL are complicated by the heterogeneity of prognosis, advanced age and comorbidities of patients, and lack of an established standard approach for treatment, making it vital that clinicians be familiar with the latest research and advances in this area. In this activity chaired by Michael Wang, MD, Professor in the Department of Lymphoma & Myeloma at MD Anderson Cancer Center, expert faculty will discuss prognostic factors informing treatment, the promising results of recent trials in new therapeutic approaches, and the implications of treatment resistance in therapeutic selection for MCL.
Target Audience
Hematology/oncology fellows, attending faculty, and other health care professionals involved in the treatment of patients with mantle cell lymphoma (MCL).
Learning Objectives
1.) Identify clinical and biological prognostic factors that can guide treatment decision making for older adults with MCL
2.) Evaluate emerging data on targeted therapeutic approaches for treatment-naive and relapsed/refractory MCL and their applicability to older adults
3.) Assess mechanisms of resistance to targeted therapies for MCL and their implications for treatment selection

Flu Vaccine Alert in Bangalore Karnatakaaddon Scans
As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions.
Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says.
This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots.
To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare.
Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself.
Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places.
Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages.
Stay informed, stay safe, and get your flu shot today!

Tom Selleck, an enduring figure in Hollywood. has captivated audiences for decades with his rugged charm, iconic moustache. and memorable roles in television and film. From his breakout role as Thomas Magnum in Magnum P.I. to his current portrayal of Frank Reagan in Blue Bloods. Selleck's career has spanned over 50 years. But beyond his professional achievements. fans have often been curious about Tom Selleck Health. especially as he has aged in the public eye.
Follow us on: Pinterest
Introduction
Many have been interested in Tom Selleck health. not only because of his enduring presence on screen but also because of the challenges. and lifestyle choices he has faced and made over the years. This article delves into the various aspects of Tom Selleck health. exploring his fitness regimen, diet, mental health. and the challenges he has encountered as he ages. We'll look at how he maintains his well-being. the health issues he has faced, and his approach to ageing .
Early Life and Career
Childhood and Athletic Beginnings
Tom Selleck was born on January 29, 1945, in Detroit, Michigan, and grew up in Sherman Oaks, California. From an early age, he was involved in sports, particularly basketball. which played a significant role in his physical development. His athletic pursuits continued into college. where he attended the University of Southern California (USC) on a basketball scholarship. This early involvement in sports laid a strong foundation for his physical health and disciplined lifestyle.
Transition to Acting
Selleck's transition from an athlete to an actor came with its physical demands. His first significant role in "Magnum P.I." required him to perform various stunts and maintain a fit appearance. This role, which he played from 1980 to 1988. necessitated a rigorous fitness routine to meet the show's demands. setting the stage for his long-term commitment to health and wellness.
Fitness Regimen
Workout Routine
Tom Selleck health and fitness regimen has evolved. adapting to his changing roles and age. During his "Magnum, P.I." days. Selleck's workouts were intense and focused on building and maintaining muscle mass. His routine included weightlifting, cardiovascular exercises. and specific training for the stunts he performed on the show.
Selleck adjusted his fitness routine as he aged to suit his body's needs. Today, his workouts focus on maintaining flexibility, strength, and cardiovascular health. He incorporates low-impact exercises such as swimming, walking, and light weightlifting. This balanced approach helps him stay fit without putting undue strain on his joints and muscles.
Importance of Flexibility and Mobility
In recent years, Selleck has emphasized the importance of flexibility and mobility in his fitness regimen. Understanding the natural decline in muscle mass and joint flexibility with age. he includes stretching and yoga in his routine. These practices help prevent injuries, improve posture, and maintain mobilit

Lung Cancer: Artificial Intelligence, Synergetics, Complex System Analysis, S...Oleg Kshivets
RESULTS: Overall life span (LS) was 2252.1±1742.5 days and cumulative 5-year survival (5YS) reached 73.2%, 10 years – 64.8%, 20 years – 42.5%. 513 LCP lived more than 5 years (LS=3124.6±1525.6 days), 148 LCP – more than 10 years (LS=5054.4±1504.1 days).199 LCP died because of LC (LS=562.7±374.5 days). 5YS of LCP after bi/lobectomies was significantly superior in comparison with LCP after pneumonectomies (78.1% vs.63.7%, P=0.00001 by log-rank test). AT significantly improved 5YS (66.3% vs. 34.8%) (P=0.00000 by log-rank test) only for LCP with N1-2. Cox modeling displayed that 5YS of LCP significantly depended on: phase transition (PT) early-invasive LC in terms of synergetics, PT N0—N12, cell ratio factors (ratio between cancer cells- CC and blood cells subpopulations), G1-3, histology, glucose, AT, blood cell circuit, prothrombin index, heparin tolerance, recalcification time (P=0.000-0.038). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and PT early-invasive LC (rank=1), PT N0—N12 (rank=2), thrombocytes/CC (3), erythrocytes/CC (4), eosinophils/CC (5), healthy cells/CC (6), lymphocytes/CC (7), segmented neutrophils/CC (8), stick neutrophils/CC (9), monocytes/CC (10); leucocytes/CC (11). Correct prediction of 5YS was 100% by neural networks computing (area under ROC curve=1.0; error=0.0).
CONCLUSIONS: 5YS of LCP after radical procedures significantly depended on: 1) PT early-invasive cancer; 2) PT N0--N12; 3) cell ratio factors; 4) blood cell circuit; 5) biochemical factors; 6) hemostasis system; 7) AT; 8) LC characteristics; 9) LC cell dynamics; 10) surgery type: lobectomy/pneumonectomy; 11) anthropometric data. Optimal diagnosis and treatment strategies for LC are: 1) screening and early detection of LC; 2) availability of experienced thoracic surgeons because of complexity of radical procedures; 3) aggressive en block surgery and adequate lymph node dissection for completeness; 4) precise prediction; 5) adjuvant chemoimmunoradiotherapy for LCP with unfavorable prognosis.

2. Gingival recession is defined as the displacement of the marginal
tissue apical to the cemento-enamel junction.1
Carranza defines recession as ‘exposure of the tooth surface by
apical migration of the gingiva’.
Histologically, the destruction of gingival tissues, due to mechanical
forces or related to inflammatory periodontal disease, is associated
with loss of periodontal connective tissue fibers and alveolar bone.
As a consequence, exposure of the root surface to oral environment
will occur.
3. Gingival recession is a sign of periodontal disease.
Gingival recession can be localized or generalized and be associated with
one or more surfaces.2
Gingival recession is a common occurrence and its prevalence increases
with age.
The recession of the gingiva, either localized or generalized, may be
associated with one or more surfaces, resulting in attachment loss and
root exposure, which can lead to clinical problems such as root surface
hypersensitivity, root caries, cervical root abrasions, difficult plaque
control and diminished cosmetic appeal and aesthetic concern. 3
4. Marginal gingival recession, therefore, can cause major functional and
aesthetic problems, and should not be viewed as merely a soft tissue
defect, but rather as the destruction of both the soft and hard tissue.
Treatment proposals for this type of defect have evolved based on the
knowledge for healing the gingiva and the attachment system.3
5. Prevalence
According to the US National Survey, 88% of seniors (age 65 and
over) and 50% of adults (18 to 64) present recession in one or more
sites; progressive increase in frequency and extent of recession is
observed with increase in age.5
6. Multifactorial Gingival Recession Etiology
Periodontal marginal tissue recessions have numerous causes, but there is a
consensus about the gingival recession etiology.
1. An anatomical condition with a pre-existing or acquired alveolar bone
dehiscence combined with localized prominent tooth malposition, inadequate
keratinized gingival dimensions in quality and quantity, high muscle attachment
and frenum pull.
2. Traumatic, overzealous tooth brushing
techniques (ie, forceful, horizontal) frequently
associated with a pre-existing lack of cortical bone,
or acquired bone dehiscence.
7. 3. Occlusal
disturbances and
parafunctional habits
like cervical dental
abrasions etc.
4. Uncontrolled
marginal
inflammation with
accumulation of
dental plaque due to
improper brushing
techniques.
5. Iatrogenic factors related to periodontal,
orthodontic and periodontal/restorative procedures
on thin biotype (eg, gingivectomy, apically positioned
flap, tooth overpreparation violating the biologic
width, incorrect fitting of the restoration with
overcontouring or a gap between the margin of the
crown and the tooth structure).
8. 6. No evident clinical etiology in 17% of gingival recession.3
Treatment Planning Decision Modality 3
If the recession is not progressing
and does not provoke tooth
sensitivity or poor aesthetics, then
tooth-brushing instructions and
regular observation through a
strict maintenance program would
be the optimal treatment.
9. Progressive gingival recession in the presence of high thermal
sensitivity and/or compromised aesthetic appearance should be treated
with surgical root coverage in Class I and II defects.
Thorough plaque control is the primary condition for the success of
any periodontal surgery.
10. Smoking is a contraindication for plastic periodontal surgery due to:
• Associated gingival vasoconstriction that often causes necrosis of the
soft tissues;
• Lack of adherence of the fibroblasts; and
• Alteration in immune response.
The ideal surgical objective is
covering the root up to the
cementoenamel junction with
a probing depth of less than 2
mm without probe-induced
bleeding.
The principal challenge lies in
obtaining an excellent blood
supply for the covering
tissues to avoid possible
necrosis and root coverage
failure.
11. It is always important to select the periodontal procedure that allows the
best aesthetic result, while causing the least amount of trauma.
Miller prescribes complete disclosure at the initial consultation concerning
the root coverage that can realistically be obtained through the selected
form of treatment (Table 1)
12. Classification of marginal tissue recession (Miller)2
Symptoms Treatment Success
Class I Recession that does not
extend to the mucogingival
junction
Complete root coverage is
achievable
100%
Class II Recession that extends to or
beyond the mucogingival
junction, with no
periodontal attachment loss
(i.e. bone,
soft tissue)
Complete root coverage is
achievable
100%
Class III Recession that extends to or
beyond the mucogingival
junction, with periodontal
attachment loss in interdental
area or malpositioning of the
teeth
Only partial root coverage
possible to the height of
contour
of interproximal tissue.
50-70%
Class IV Recession that extends to or
beyond the mucogingival
junction, with severe bone
or soft-tissue loss in
interdental area
and/or severe malpositioning
of teeth.
Root coverage is
unpredictable
and requires adjunctive
treatment (i.e. orthodontics)
<10%
13. A number of reports published on recession treatment emphasize the size
of the presurgical defect and its effect on clinical outcomes; in other words,
the deeper and narrower the defect, the greater the achieved root
coverage.
Deeper recessions (ie, 4 mm or more) had greater attachment level gains
than shallow (ie, less than 4 mm) recessions.
The mean percentage of root coverage reported for the subepithelial CT
grafts technique varies between 65% and 98%, while the percentage of
complete root coverage ranges from 0% to 90% depending on the recession
classification.
14. Pre-requisites of Gingival Recession Surgery3
Indications Contraindications
Small amount of keratinized gingiva
Class I or II recessions
Aesthetic concerns
Single or multiple recessions
Large and deep recessions
Exposed root sensitivities
Insufficient or inefficient patient
hygiene
Smoking patient
Desquamative gingivitis
15. There are currently 4 common basic categories for root coverage:
In addition, combinations of different procedures are also popular in
many clinical practices and literature reports.
pedicle
grafts
guided tissue
regeneration
techniques with
a membrane
barrier
16. Treatment of the Exposed Root Surface6
Before root coverage is attempted, the exposed portion of the root
should be rendered free from bacterial plaque.
The presence of a filling in the root does not preclude the possibility
for root coverage, but the filling should be removed before the root is
covered with soft tissue.
Miller advocated the use of root surface demineralization agents as an
important treatment component in the free soft tissue graft procedure.
17. This also allows subsequent inter-digitation of these fibrils with those
in the covering connective tissue.
Flap tension has been reported to be an important factor for the
outcome of the coronally advanced flap procedure.
The best clinical result is achieved if the flap is passively adapted to
the root surface.
18. Current muco-gingival plastic surgical techniques for treating gingival
recession - Laterally positioned pedicle graft4
The best-known technique among pedicle grafts is the laterally positioned
pedicle graft introduced by Grupe and Warren and later modified by Grupe.
The success rate of this root coverage procedure was found to be in the
range of 69% ~ 72%.
In this procedure, the adjacent keratinized gingiva is positioned laterally,
and the exposed root surface in the localized gingival recession is
covered.
Guinard and Caffesse reported an average of 1mm postoperative gingival
recession on the adjacent donor site.
19. The main advantages of the laterally positioned pedicle graft are that it is
relatively easy and not time-consuming, it produces excellent esthetic
results, and a second surgical site is not mandatory.
To reduce the risk for recession on the donor tooth, Grupe suggested that
the marginal soft tissue should not be included in the flap.
20. INDICATIONS:
Sufficient width, length, and thickness of keratinized tissue exist
adjacent to the area of gingival recession.
Coverage of the exposed root is limited to one to two teeth.
This method is most suitable for root coverage in gingival recession
with narrow mesiodistal dimension ( eg. Mandibular anterior area).
21. Contraindications
Insufficient width and thickness of keratinized tissue in the adjacent
donor site.
Extremely thin bone in the donor site or an osseous defect such as a
dehiscence or fenestration.
Gingival recession area extremely protrusive.
Deep periodontal pocket and remarkable loss of interdental alveolar
bone in the adjacent area.
Narrow oral vestibule.
Multiple teeth involved.
22. Pfeifer and Heller advocated the use of a split-thickness flap to minimize
the potential risk for development of dehiscence at the donor tooth.6
The disadvantages, however, include that it is applicable only for
single-site recession, there is a possible danger of gingival recession,
dehiscence, or fenestration at the adjacent donor site, and an
adequate amount of keratinized tissue at a neighboring donor site and
a deep vestibule are needed.
23. Step 1: Make incision on gingival margin around exposed roots.
Remove resected soft tissue. Root planing.
Step 2: A full/ partial thickness flap may be reflected. Make vertical
incision from GM to outline a flap adjacent to recipient site. the flap
should be wider than the recepient site.
24. Step 3: Separate flap consisting epithelium and a thin layer of
connective tissue.
Step 4: Slide the flap laterally onto the adjacent root.
Step 5:Fix the flap to adjacent root and suture
Cover the operative field with tin foil and place a periodontal pack.
25. There are also other alternative procedures for a laterally positioned
flap, such as a double papilla graft (Cohen and Ross) and an obliquely
rotated graft (Pennel).
The double papilla graft has very limited usefulness due to its poor
predictability, although the esthetic result is excellent.
The obliquely rotated graft has the same disadvantages as the laterally
position pedicle flap, although it can avoid other tension-releasing
incisions as does the laterally positioned pedicle flap.
26. Coronally Positioned Flap6
Coronally positioned flap is a technique used to cover exposed roots
with the available gingiva.
This technique has a major drawback because when significant
recession occurs, there is rarely enough gingival width or
thickness to completely cover the exposed root.
The ideal case for a coronally positioned flap is a patient who has
adequate thickness and width of the gingiva on the marginal edge
of the flap to be advanced.
The keratinized gingiva has to be wide enough to secure the
sutures and maintain a stable, tension-free gingival flap during the
healing process .
27. The advantages of the coronally positioned flap technique are that only
1 surgical site is involved and it is an excellent color match.
Case selection is important because if the grafted tissue is thin, only
partial root coverage is achieved, and the tissue is prone to additional
recession.
In some cases, a split-thickness dissection is performed, while in other
cases, a full-thickness flap is used over the radicular surface of the root
to maintain a sufficient flap thickness.
28. The pedicle flap is then
advanced in a coronal
direction until it comes to
rest on the recipient bed for
a trial fit.
The fit should be a butt joint
where the flap is inlayed into
or exactly fits into the
recipient site.
Once the tissue lies passively in
place, it should be sutured.
Proper suturing should be
accomplished without any
tension on the flap.
29. Free gingival graft 4
The free gingival graft procedure involves a combination of 2 tissue
components (keratinized epithelial and connective tissue) obtained
from the palate or an edentulous ridge and its placement in the
gingival recession area.
Hattler was the first to utilize keratinized gingiva of the interdental
papillae to cover denuded root surfaces.
The technique was popularized later by Sullivan and Atkins and was
further refined by other investigators including Sugarman and
Staffileno and Levy.
Results obtained from different studies indicated that the mean root
coverage treated with a free gingival graft was 88%, with the total root
coverage varying from 70% to 90% of the treated sites.
30. The promising advantages of this
technique are that it is a relatively
easy technique, it can be applied to
both single and multiple recessions,
it does not depend on adjacent sites
for donor tissue, and its usage is
not relevant to vestibular depth.
The disadvantages is that it creates a
second donor site wound that is prone to
bleeding, pain, and slow healing and it
produces an esthetically less-pleasing result
of the healed tissue, such as pale color and
an irregular surface of the graft site,
especially if the rugae of the palatal mucosa
are included in a large piece of donor tissue.
31. Sub-epithelial connective tissue graft (sCTG) 4
Because of these drawbacks of free gingival graft mentioned above, the
use of free connective tissue grafts for root coverage was introduced by
Edel in 1974.
The technique was presented by Langer and Calagna as a sub-epithelial
connective tissue graft, and was further described in detail by Langer and
Langer. This method is suitable for covering recessions of both single and
multiple adjacent teeth and is especially indicated when esthetics is a
primary consideration.
32. The addition of connective tissue under any pedicle flap
yields a mean exposed root coverage of 89.3%, which is
better than other soft tissue grafting tissue techniques.
The harvesting of donor tissue from the
subepithelial connective tissue of the palate
requires a complete knowledge of the anatomy of
the palate.
The best quality connective tissue is
found closest to the teeth rather than
the midline of the palate.
33. Individuals with thin periodontal biotypes are susceptible to gingival
recession. They often have thin palatal mucosa that may not be
adequate for grafting.
In these patients, another periodontal surgical procedure should be
considered. The width of connective tissue needed for most grafts is
determined by the extent of root exposure and the amount of root
coverage anticipated
34.
35.
36. Another version of a connective tissue graft was later modified by
Nelson and Harris.
Nelson modified the original technique by using a pedicle flap to cover
the connective tissue graft and called it a sub-pedicle connective tissue
graft, while Harris further modified this technique by using a bilateral
pedicle flap to cover the connective tissue graft. He called this
technique double pedicle flaps with a connective tissue graft.
The predictability of connective tissue graft procedures is generally
excellent.
For any given site, Nelson reported a mean root coverage of 88%, while
both Levine and Harris reported ~97% root coverage.
37. Long-term results (27.5 months) of subepithelial connective tissue grafts
have recently been shown to be effective (98.4%) in obtaining root
coverage in 100 patients with 146 Miller class I or II recession defects.
The subepithelial connective tissue graft was reported to be a predictable
method to obtain root coverage (with a mean root coverage of 91.1%) of
recession defects on molars and on other sites (95.8%).
There were an improvement in recession depth (from 4.4 to 0.5 mm), an
increase in the quantity of keratinized tissue (from 0.9 to 3.1 mm), a
decrease in probing depth (from 3.0 to 2.3 mm), and a decrease in
attachment level loss (from 7.4 to 2.8 mm)
38. The main advantages of this current procedure are that:
- it maintains a blood supply to the graft and therefore has a good
predictability of success;
- it provides good esthetics with preservation of the original flap tissue;
- the donor site wound is less hemorrhagic and painful, and can be healed
by primary closure; and
-it is simultaneously applicable to both single and multiple recessions.
However the critical disadvantage is the fact that this technique is
technically demanding and more time-consuming.
39. Guided tissue regeneration (GTR) technique4
In looking for a new attachment or regeneration of tissues at the site of
recession, recent clinical studies have proposed the guided tissue
regeneration (GTR) technique for the treatment of gingival recession.
Tinti and collaborators are pioneers of this treatment modality. They
have introduced techniques for GTR to obtain root coverage in an
attempt to re-establish a connective tissue attachment on exposed root
surfaces. Pini Prato et al. also exploited guided regeneration techniques
to simultaneously treat osseous defects, exposed roots, and
mucogingival problems.
The predictability and success rate of the GTR procedures used for
treating gingival recession were addressed in many recent studies and
varied from 45% to 81% with more than 100% improvement in the width
of the keratinized gingiva.
40.
41.
42. The main advantages of this procedure include
- good esthetics,
- a reasonable potential for true regeneration of the lost periodontal
attachment, and
- the absence of the need for a second donor site.
The disadvantages are that
- it requires 2 surgical stages when non-resorbable membranes are used;
- it is potentially more expensive;
- more effort is required to care for the wound postoperatively;
- and the percentage of root coverage is not usually optimal due to
common membrane exposure and colonization of oral microbiota on
the membrane.
43. Favorable outcomes for root coverage have recently been reported using
bio-absorbable membranes.
However, the amount of root coverage obtained with a coronally
positioned flap (CPF) was greater than that observed with GTR.
Unfavorable clinical results were reported in a shallow recession study
using a coronally positioned flap in combination with a bio-resorbable
membrane.
The GTR procedure was also reported to produce a mean root coverage of
75.1% in comparison with a mean root coverage of 97.1% in the connective
tissue graft with a partial-thickness double pedicle flap.
The less-favorable clinical outcome with the GTR method was further
confirmed in a recent meta-analysis.
44. Combination of a CPF with an acellular dermal matrix 4
Due to the presence of many disadvantages associated with CTG, that
procedure combined with an acellular dermal matrix allograft (ADMA) and a
coronally positioned pedicle flap (CPF) has been evaluated as a substitute
for free CTGs in various periodontal procedures, including root coverage.
Root coverage using an acellular dermal matrix graft material and a
coronally positioned flap has thus initially been applied to treat cases with
gingival recession. The long-term stability of the root coverage results
obtained with a graft using an acellular dermal matrix was also
demonstrated by Harris.
Based on evidence shown earlier, the root coverage obtained with an
acellular dermal matrix is predictable, esthetic, and stable over time.
45. Combination of a CPF with an enamel matrix derivative4
Most of the current literature suggests that the sCTG has the
highest percentage of mean root coverage with the least variability.
Again, due to several unresolved disadvantages with this
technique, an enamel matrix derivative (EMD) has recently been
introduced in the periodontal field to overcome short-comings
associated with this and currently available regenerative
techniques.
EMD is an extract of enamel matrix and contains amelogenins of
various molecular weights. There is evidence to show that
amelogenins are involved not only in enamel formation, but also in
formation of the periodontal attachment during tooth formation
46. Despite the overall efficacy of EMD regeneration therapy, a
significant variation (similar to the results for GTRs) in clinical
outcomes was observed.
Meanwhile, the current literature also discloses no evidence of
clinically important differences between GTR and Emdogain
treatments in terms of probing attachment level gain and probing
depth reduction.
Preliminary histologic investigations with surgically created defects
and experimental periodontal lesions illustrated the potential of
EMD to induce formation of acellular cementum and promote
significant formation of the supporting periodontal tissues in human
and animal experiments.
47. However, recent human histologic studies have questioned both the
consistency of the histologic outcomes and the ability of EMD to
predictably stimulate formation of acellular cementum and bone.
Non-functional orientation of the newly formed periodontal
ligament collagen fibers was often observed.
These findings, coupled with the inconsistent bone growth bring
into question both the ability of EMD to predictably induce true
periodontal regeneration in patients and the consistency of the
histologic outcome.
48. The periosteum is a highly vascular connective tissue sheath covering
the external surface of all the bones except sites of articulation and
muscle attachment.
The periosteum comprises of at least two layers, an inner cellular or
cambium layer and an outer fibrous layer.
The inner layer contains numerous osteoblasts and osteoprogenitor
cells and the outer layer is composed of dense collagen fiber,
fibroblasts and their progenitor cells; osteogenic progenitor cells from
the periosteal cambium layer may work with osteoblasts in initiating
and driving the cell differentiation process of bone repair.
Periosteal pedicle graft7
49. Research on the structure of periosteum has shown that it is made up of
three discrete zones.
Zone 1 has an
average thickness of 10-20um
consisting predominantly of
osteoblasts representing 90%
of cell population, while
collagen fibrils comprise 15%
of the volume.
Zone 3 has the highest
volume of collagen
fibrils and fibroblasts
among all the three
Zones.
The majority of cells
in zone 2 are
fibroblasts, with
endothelial cells
being most of the
remainder.
50. Recent papers published have
shown promising results with
the use of periosteum in the
treatment of gingival
recession defects.
After local
anaesthesia, an
intrasulcular
incision is given
with 15c Bard
Parker surgical
blade at the
buccal aspect of
the involved
tooth.
Two horizontal incisions are then made perpendicular to the
adjacent interdental papillae, at the level of the CEJ preserving
the gingival margin of the neighbouring teeth.
51. Two oblique vertical incisions were extended beyond the
mucogingival junction and a full thickness trapezoidal flap is
raised 3–4 mm apical to the osseous crest which is then
pulled buccally to create tension on the periosteum.
An incision is made through the periosteum where the flap
was still attached to the bone, to create a partial thickness
flap.
The partial thickness flap was extended to expose a sufficient
amount of the periosteum which is then separated from the
underlying bone using a Glickman periosteal elevator .
The process of separating the periosteum is initiated at the
apical extent of the periosteum which is then lifted slowly in a
coronal direction.
52. The periosteum is not separated completely from the underlying bone,
leaving it attached at its coronal most end .The periosteal pedicle graft
(PPG) thus obtained is then turned over the exposed root surface and
sutured with a synthetic 5-0 bioabsorbable suture.
After stabilizing the periosteal graft, the flap is coronally positioned and
sutured using a sling suture technique with a non-resorbable 4-0 silk
suture .
The releasing incisions are closed with interrupted sutures after which the
operated site is covered with non-eugenol periodontal dressing (coe-Pak)
for protection.
53. Advantages of Periosteal Pedicle Graft:
When used as a graft for the treatment of gingival recession defects
periosteum has shown promising results. The advantages associated with
PPG are:
• The presence of periosteum adjacent to the defect and in sufficient
quantity.
• Avoiding two surgical sites resulting in less surgical trauma,
postoperative complications.
• Better patient satisfaction.
54. Similar to connective tissue grafts, the connective tissue component of the
graft may be sufficient to support the documented clinical outcomes.7
Although the exact mechanism involved behind the excellent results
associated with PPG are still not known it is a possibility that the clinical
effectiveness of the periosteal pedicle graft for root coverage may not be
due to the cellular component of the graft.
55. Tunnel Connective Tissue Graft (TCTG)3
A sulcular incision was designed on both sides, from the first premolar to
the central incisors, and a partial dissection was carefully performed in
order to create a deep pouch beyond the mucogingival junction while
keeping the tip of the interproximal papillae attached to the teeth below
the proximal contact point.
A primary flap on the right and left palatal sites with one line of incision
allows the harvesting of thick, sizable connective tissue. The primary flap
was immediately sutured to prevent bleeding.
The CTG, using 4-0 sutures, was delicately inserted inside the pouch and
was then stabilized with the flap using 5-0 Vicryl sutures. The healing
progressed unevent- fully and the gingival recession was totally covered
with a beautiful aesthetic result on both sides
56. Advantages Disadvantages
Excellent adaptation on the
recipient site
Highly aesthetic results
High vascularization by the
advanced flap
Increased thickness of the
keratinized gingiva
Harmony in the gingival
color/texture
Traumatic surgery for the
patient
Requires two surgical sites
Delicate harvesting of the graft
Difficult stabilization of the
graft
Palatal graft has limited
quantity and thickness
Lengthy surgery/healing
57. Conclusion
Gingival recession is one of the main esthetic complaints of patients.
This also exposes patients to sensitivity and greater risk for root
caries. Mucogingival surgery endeavors’ to reestablish the
periodontium to a healthy circumstance Periodontal plastic surgery
strives to restore the periodon- tium to a healthy, efficient, and
aesthetic state. For coverage of exposed roots, there is a vast range
of mucogingival grafting procedures available in the present epoch.
These procedures are quite predictable and produce satisfactory
solutions to the problems presented by gingival recessions. Choice
of appropriate procedure and surgical technique will recommend
successful and exceedingly predictable results in the management of
gingival recession .5
