This document discusses aggressive periodontitis, including its history, classification, localized aggressive periodontitis, and generalized aggressive periodontitis. It defines aggressive periodontitis as a specific type of periodontitis featuring rapid attachment loss, bone destruction, and familial aggregation, with inconsistent microbial deposits and severe tissue destruction. Localized aggressive periodontitis is characterized by circumpubertal onset and localized first molar/incisor involvement. Generalized aggressive periodontitis affects at least three teeth other than first molars and incisors and has an episodic nature. Both forms are associated with elevated levels of certain bacteria and potential immunological and genetic factors.
The future of dentistry and periodontics lies in regeneration. The goals of periodontal therapy lies in not only the arrest of periodontal disease progression but also regeneration of the lost periodontal structures. This presentation provides a review of the current understanding of the regeneration of the periodontium and the procedures involved to restore the periodontal tissues around the teeth.
Furcation involvement is a common sequela of severe chronic periodontal disease. Its effective management has a profound influence on the outcome of periodontal therapy.

Periodontitis is a chronic infectious inflammatory disease caused by microbes; however the presence of microbes is not enough for the cause of its complex nature of disease. Inflammation is the prime cause of periodontal disease. It commences with the aggregation of pathogenic microbes that induce the host to stimulate a cascade of inflammatory response reactions which in-turn leads to the destruction of the host tissues itself. There is a complex interplay of innate and adaptive immune responses which fights against the pathogens by direct interaction or by release of certain molecules including cytokines.
Cytokines are cell signalling molecules that aid cell to cell communication in immune responses and stimulate the movement of cells towards sites of inflammation, infection and trauma. Cytokine biology reveals that there are some subsets of cytokines which are pro-inflammatory cytokines which stimulate the inflammatory responses and cause tissue destruction.
A periodontist is expected to have a sound basis of the cytokine profile to understand the pathogenesis of periodontitis and also to discover the new treatment modality of anti-cytokine therapy.

Why is there localisation of disease to 1st molars and incisors in LAP?
Often subjects present with attachment loss that does not fit the specific diagnostic criteria (AP or chronic periodontitis).
Schenkein et al. 1995: cigarette smoking was shown to be a risk factor for patients with generalized forms of AgP.
Smokers with GAP had more affected teeth and greater mean levels of attachment loss than patients with GAP who did not smoke.
IgG2 serum levels as well as antibody levels against A.a. are significantly depressed in subjects with GAP who smoked.

Peripheral Ossifying Fibroma: A Case Reportiosrjce
IOSR Journal of Dental and Medical Sciences is one of the speciality Journal in Dental Science and Medical Science published by International Organization of Scientific Research (IOSR). The Journal publishes papers of the highest scientific merit and widest possible scope work in all areas related to medical and dental science. The Journal welcome review articles, leading medical and clinical research articles, technical notes, case reports and others.
The presence of furcation involvement is one clinical finding that can lead to a diagnosis of advanced periodontitis and potentially to a less favourable prognosis for the affected tooth or teeth. Furcation involvement therefore presents both diagnostic and therapeutic dilemmas. This review explains the vast aspects of furcation involvement in form of etiology, classification, diagnosis and different treatment modalities in detail.
Key Words: Furcation, periodontitis, plaque.
Gingival recession—can orthodontics be a cure? evidence from a case presentationEdwardHAngle
Does orthodontic treatment help or hinder a patient’s periodontal status? What factors affect the
periodontium? Can those factors be managed in a way that remedies existing periodontal issues?
A 35-year-old woman presented with severe gingival recession and a unilateral Class II
malocclusion. The treatment plan was to correct the malocclusion in a way that torques the roots
more onto bone and to change her dental hygiene methods. With an extensive review of the
literature, this case review attempts to make sense of the enigma of gingival recession and
demonstrates an excellent treatment solution to concomitant orthodontic and periodontal
problems.
Periodontitis is a chronic, slowly progressing disease which mainly results in the destruction of tooth supporting apparatus. Earlier it was classified as Chronic and Aggressive periodontitis with different clinical features and etiology. Current classification ( 2017) of periodontal disease involves periodontitis with is further divided into 4 stages and 3 grades depending on severity and rate of disease progression respectively. Diabetes meelitus and smoking are the validated risk factors for the progression of periodontitis.
Peripheral ossifying fibroma (POF) is a non-neoplastic enlargement of the gingival, which is one of the main
benign, reactive hyperplastic inflammatory lesions of the gingiva occurring in young adults. It has a very high
recurrence rate of around 7-45%. For this reason, a longer patient follow-up is very important in POF. Peripheral
ossifying fibroma comprises about 9% of all gingival growths. POF has similar clinical presentations with different
lesions which makes it difficult to reach at a correct diagnosis. In this article, we are reporting a case of peripheral ossifying fibroma (POF) in a 16-year-old female patient.

The prostate is an exocrine gland of the male mammalian reproductive system
It is a walnut-sized gland that forms part of the male reproductive system and is located in front of the rectum and just below the urinary bladder
Function is to store and secrete a clear, slightly alkaline fluid that constitutes 10-30% of the volume of the seminal fluid that along with the spermatozoa, constitutes semen
A healthy human prostate measures (4cm-vertical, by 3cm-horizontal, 2cm ant-post ).
It surrounds the urethra just below the urinary bladder. It has anterior, median, posterior and two lateral lobes
It’s work is regulated by androgens which are responsible for male sex characteristics
Generalised disease of the prostate due to hormonal derangement which leads to non malignant enlargement of the gland (increase in the number of epithelial cells and stromal tissue)to cause compression of the urethra leading to symptoms (LUTS
Acute scrotum is a general term referring to an emergency condition affecting the contents or the wall of the scrotum.
There are a number of conditions that present acutely, predominantly with pain and/or swelling
A careful and detailed history and examination, and in some cases, investigations allow differentiation between these diagnoses. A prompt diagnosis is essential as the patient may require urgent surgical intervention
Testicular torsion refers to twisting of the spermatic cord, causing ischaemia of the testicle.
Testicular torsion results from inadequate fixation of the testis to the tunica vaginalis producing ischemia from reduced arterial inflow and venous outflow obstruction.
The prevalence of testicular torsion in adult patients hospitalized with acute scrotal pain is approximately 25 to 50 percent
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
Ethanol (CH3CH2OH), or beverage alcohol, is a two-carbon alcohol
that is rapidly distributed in the body and brain. Ethanol alters many
neurochemical systems and has rewarding and addictive properties. It
is the oldest recreational drug and likely contributes to more morbidity,
mortality, and public health costs than all illicit drugs combined. The
5th edition of the Diagnostic and Statistical Manual of Mental Disorders
(DSM-5) integrates alcohol abuse and alcohol dependence into a single
disorder called alcohol use disorder (AUD), with mild, moderate,
and severe subclassifications (American Psychiatric Association, 2013).
In the DSM-5, all types of substance abuse and dependence have been
combined into a single substance use disorder (SUD) on a continuum
from mild to severe. A diagnosis of AUD requires that at least two of
the 11 DSM-5 behaviors be present within a 12-month period (mild
AUD: 2–3 criteria; moderate AUD: 4–5 criteria; severe AUD: 6–11 criteria).
The four main behavioral effects of AUD are impaired control over
drinking, negative social consequences, risky use, and altered physiological
effects (tolerance, withdrawal). This chapter presents an overview
of the prevalence and harmful consequences of AUD in the U.S.,
the systemic nature of the disease, neurocircuitry and stages of AUD,
comorbidities, fetal alcohol spectrum disorders, genetic risk factors, and
pharmacotherapies for AUD.

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.

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!
3. Destructive periodontal diseases affecting the connective tissue attachment
& alveolar bone supporting the teeth have long been considered the
principal cause for tooth loss.
At the 1999 International classification workshop, the different forms
of periodontitis were reclassified into three major forms (chronic,
aggressive, necrotizing forms of periodontitis and periodontal
manifestations of systemic diseases).

LOCALISED AGGRESSIVE PERIODONTITIS
15. PREVALENCE AND DISTRIBUTION
It is estimated to be below 1%.
Blacks– mostly male blacks- 2.9 times more likely to have disease than black
females.
(Baer 1971, Manson and Lehner 1974) concluded female to male ratio as 3:1
Primary dentition: In 5 to 11 year olds it ranges from 0.9 - 4.5% of subjects
(Sweeney et al 1987)
Permanent dentition: In the permanent dentition of 13-20 year old individuals
majority of studies have reported a prevalence of periodontitis of less than 1%
(usually 0.1-0.2% in caucasian population).
Lang LP and Carring T. Aggressive periodontitis In: Lindhe’s Clinical periodontology and implant dentistry. Elsevier 5:438-460.
16. CLINICAL FINDINGS
Localized first molar/incisor with interproximal attachment loss.
The most striking feature
Lack of clinical inflammation, despite the presence of deep
periodontal pockets
17. Disto-labial migration of
central incisor in LAP
Periodontal Abscess
Deep, dull radiating pain
may occur with mastication.
Regional lymph node
enlargement
18. Clinically there is small amount of plaque ,which
forms a thin film on the tooth that rarely mineralizes
to become calculus.
Most commonly there is migration and mobility of
first molars and incisors. Classically the maxillary
incisors move in distolabial direction.
Concomitant to anterior tooth migration there is an
apparent increase in size of the clinical crown.
Lang LP and Carring T. Aggressive periodontitis In: Lindhe’s Clinical periodontology and implant dentistry. Elsevier 5:438-460.
19. RADIOGRAPHIC FINDINGS
Vertical loss of alveolar bone around first
molars and incisors.
Rate of bone loss is 3-4times faster than in
chronic periodontitis.
Arc-shaped bone loss from distal of 2nd
Premolar to Mesial of 2nd Molar and often
presents a mirror-image pattern on the
radiograph.
Bone defects usually bilateral, affecting 1st
Molars & Incisors.
Lang LP and Carring T. Aggressive periodontitis In: Lindhe’s Clinical periodontology and implant dentistry. Elsevier 5:438-460.
20. Although the most important measurement is that of attachment loss
by probing in younger subjects a currently utilized approach is
measurement of distance between CEJ and alveolar crest on bitewing
radiographs.
21.
22. DISTRIBUTION OF LESION
The classical distribution of lesions in first molar / incisor region may be
explained by following :
After initial colonization of the first permanent teeth to erupt (first
molars and incisors) A.a evades the host defenses by different
mechanisms. After initial attack, adequate immune responses are
stimulated to produce opsonizing antibodies to enhance phagocytosis of
invading bacteria and neutralize destructive factors. In this manner
colonization of other sites may be prevented. (Zambon1983).
Armitage G C, Cullinan M. Comparison of the clinical features of chronic and aggressive periodontitis. Periodontol 2000; 2010,53:12–27.
23. Bacteria antagonistic to A.a may develop, thereby decreasing the
destructiveness of the lesions and reducing the number of colonization
sites (Hillman 1982).
A.a may lose its leukotoxin producing ability for unknown reasons.
When this happens the progress of the disease becomes arrested or
retarded and new colonization sites averted.
Armitage G C, Cullinan M. Comparison of the clinical features of chronic and aggressive periodontitis. Periodontol 2000; 2010,53:12–27.
24. The possibility that a defect in cementum formation may be responsible
for localization of the lesion has been suggested (Page 1985). Root
surfaces of teeth extracted from patients with LAP have been found to
have hypoplastic or aplastic cementum (Lindskong 1983)
25. CLINICAL COURSE
LAgP progresses rapidly.
There is evidence that rate of progression is about three to four times
faster than found in typical periodontitis (Baer 1971,1974).
In affected persons bone resorption progresses until the teeth are treated,
exfoliated or extracted.
Lang LP and Carring T. Aggressive periodontitis In: Lindhe’s Clinical periodontology and implant dentistry. Elsevier 5:438-460.
26. BURN-OUT PHENOMENON
• Initially it was thought that LAP gradually becomes GAP over time. But
some cases of LAP don’t show any increased bone destruction, are
known to arrest spontaneously, leading to caessation of disease activity.
• Proposed by Ranney.
Novak K F and Novak J M:Aggressive Periodontitis in Carranza’s clinical periodontology,Elsevier,12,2010;506-512.
27. SEQUELAE OF LOCALIZED
AGGRESSIVE PERIODONTITIS
Hormand and Frandsen (1979) in a study of 156 patients, presented
evidence for progression of the disease from a localized to generalized
form.
Case report by Shapira, Van Dyke et al (1994) of periodontitis patients
who were followed up for many years and findings are:
Idiopathic Prepubertal periodontitis at age 10.
LJP at age 22, bone loss involving all the permanent first molars and
maxillary and mandibular incisors.
Rapidly progressive periodontitis at age 29.
Lang LP and Carring T. Aggressive periodontitis In: Lindhe’s Clinical periodontology and implant dentistry. Elsevier 5:438-460.
30. Generalised Aggressive Periodontitis usually affects person
under 30 years of age or may be older with generalised
interproximal attachment loss affecting at least three teeth other
than first molars and incisors and there is a pronounced episodic
nature of the destruction of attachment and alveolar bone having
poor serum antibody response to infecting agents.
(Glossary of periodontal terms 2001,4th ed)
American Academy of Periodontology. Glossary of periodontal terms.4;2001.
31. PREVALENCE AND DISTRIBUTION
Loe and colleagues (1986), in a study of Sri Lankan subjects aged 14 –
46 yrs showed that 8 % of the population had rapid progression of
periodontal disease characterized by yearly loss of attachment of 0.1 to
1mm.
National survey of adolescents in U.S, aged 14-17 yrs old. ( Loe &
Brown, 1991) prevalence rate – 0.13 %
Blacks were found to be at much higher risk than whites for all forms of
AgP .
Males were more likely to have GAP than females.
Lang LP and Carring T. Aggressive periodontitis In: Lindhe’s Clinical periodontology and implant dentistry. Elsevier 5:438-460.
32. CLINICAL FINDINGS
As seen in LAP, patients with GAP often show small amount of bacterial plaque
associated with affected areas.
Quantitatively the amount of plaque is inconsistent with the amount of destruction
seen. Qualitatively P.gingivalis, A.a and T.forsythus are frequently detected.
Generalized interproximal attachment loss affecting atleast three permanent teeth
other than first molars and incisors.
Pronounced episodic destruction of attachment and alveolar bone.
Poor serum antibody response to infecting agents.
< 30years of age, but patients may be older.

inflammation and occasionally with
some degree of stippling– NON-
DESTRUCTIVE STAGE.
#Deep pockets
#Bone & attachment levels relatively
stable (Period of Quiscence)
Lang LP and Carring T. Aggressive periodontitis In: Lindhe’s Clinical periodontology and implant dentistry. Elsevier 5:438-460.
34. The destruction appears to occur episodically
followed by stages of quiescence of variable
time.
Sometimes patients may also present with
systemic manifestations like weight loss,
mental depression, general malaise.
Lesions may be arrested or spontaneous after
therapy, whereas others may continue to
progress inexorably to TOOTH LOSS
despite intervention with conventional
therapy.
Lang LP and Carring T. Aggressive periodontitis In: Lindhe’s Clinical periodontology and implant dentistry. Elsevier 5:438-460.
35. RADIOGRAPHIC FINDINGS
No definite pattern of distributiom.
The radiographic picture in GAgP can range from severe bone loss associated
with number of teeth to advanced bone loss affecting majority of the teeth in
the dentition.
Lang LP and Carring T. Aggressive periodontitis In: Lindhe’s Clinical periodontology and implant dentistry. Elsevier 5:438-460.
36. BONE LOSS IN GAgP
Page and co-workers demonstrated osseous destruction ranging
from 25-60% during a 9-week period.
Despite this extreme loss other sites in the same patient showed no
bone loss.
Lang LP and Carring T. Aggressive periodontitis In: Lindhe’s Clinical periodontology and implant dentistry. Elsevier 5:438-460.
37. INCIDENTAL ATTACHMENT LOSS
Often subjects present with attachment loss that does not fit the specific
diagnostic criteria. (AP or CP)
It includes:
• Recessions associated with trauma or tooth position.
• Attachment loss associated with impacted 3rd molars, removal of
impacted 3rd molars, etc.
• These patients are a high-risk group for AP or CP.
Novak K F and Novak J M:Aggressive Periodontitis in Carranza’s clinical periodontology,Elsevier,12,2010;506-512.
39. MICROBIOLOGIC FACTORS
Acceptance of bacterial etiology of aggressive forms of
periodontitis has been particularly difficult since clinical
presentation of cases frequently shows little visible plaque
accumulation.
Of great importance is microscopic studies demonstrating
the layer of bacterial deposits on the root surface of
advanced AgP lesions (Listgarten 1976).
KononenE , Muller H. Microbiology of aggressive periodontitis. Periodontol 2000;2014,65: 46–78.
40. DOMINANT ORGANISMS
1. A.a (Approx. 90%)
2. Capnocytophaga sp
3. E.Corrodens
4. P.intermedia
5. Motile anaerobic
rods, such as
C.rectus
6. Gram-positive
isolates were mostly.
• Streptococci
• Actinomycetes
• Peptostreptococci
1. P.gingivalis
2. A.a
3. Bacteroides forsythus
LAP
GAP
KononenE , Muller H. Microbiology of aggressive periodontitis. Periodontol 2000;2014,65: 46–78.
41. A.a has been implicated as the primary pathogen associated with LAP. As summarized
by Tonetti and Mombelli, it is based on the following evidence.
1. It is found in high frequency (approx.90%) in lesions characteristic of LAP.
2. Sites with evidence of disease progression often show elevated levels of A.a.
3. Many pts with the clinical manifestations of LAP have significantly elevated serum
antibody titers to A.a.
4. Clinical studies show a correlation between reduction in the subgingival load of A.a
during treatment and a successful clinical response.
5. It produces a no. of virulence factors that may contribute to the disease process.
KononenE , Muller H. Microbiology of aggressive periodontitis. Periodontol 2000;2014,65: 46–78.
42. DETERMINANTS OF VIRULENCE AND
PATHOGENIC POTENTIAL OF A.
ACTINOMYCETEMCOMITANS
FACTOR SIGNIFICANCE
Leukotoxin Destroys human PMNs and
macrophages
Endotoxin Activates host cells to secrete
inflammatory mediators (PGs,IL-1β,
TNF-α)
Bacteriocin Inhibit growth of beneficial species
Immunosuppressive factors Inhibit IgG and Ig M production
Collagenase Cause degradation of collagen
Chemotactic inhibition factors Inhibit neutrophil chemotaxis
KononenE , Muller H. Microbiology of aggressive periodontitis. Periodontol 2000;2014,65: 46–78.
43. GENETIC FACTORS
Segregation and Linkage analysis studies have shown an autosomal dominant
pattern of inheritance.
(Saxen & Nevanlinna 1984, Beaty et al 1987, Hart et al 1992)
Marazita et al 1994 carried out the largest and most comprehensive
segregation analysis and concluded autosomal dominant model of inheritance.
Antibody response to periodontal pathogens particularly A.a is under genetic
control, and that the ability to mount high titers of specific, protective antibody
(primarily IgG2) against A.a may be race dependent.
Vieira A , Albandar J. Role of genetic factors in the pathogenesis of aggressive periodontitis. Periodontol 2000; 2014,65:92–106.
44. Boughman et al 1986 carried out a linkage study and concluded
linkage of Juvenile Periodontitis to a Vitamin D binding locus on
chromosome 4.
Hart et al in 1993 suggested that a locus responsible for AgP was
located on chromosome 1q25.
Lastly it supports a semigeneral transmission model which says that a
few loci with small effects contribute to AgP, with possibly the
influence of environmental factors.

45. Lang LP and Carring T. Aggressive periodontitis In: Lindhe’s Clinical periodontology and implant dentistry. Elsevier 5:438-460.
46. ENVIRONMENTAL FACTORS
The amount and duration of smoking is important variable to influence
the extent of destruction seen in young adults.
Patients with GAgP with smoking habit have more affected teeth and
more attachment loss than nonsmoking patients with GAgP.
Smoking may not have the same influence on LAgP.
Lang LP and Carring T. Aggressive periodontitis In: Lindhe’s Clinical periodontology and implant dentistry. Elsevier 5:438-460.
47. Schenkein et al. 1995: Cigarette smoking was
shown to be a risk factor for patients with generalized
forms of AgP.
Smokers with GAP had more affected teeth and
greater mean levels of attachment loss than patients
with GAP who did not smoke.
IgG2 serum levels as well as antibody levels against
A.a are significantly depressed in subjects with GAP
who smoked.
48. IMMUNOLOGIC OR HOST RELATED
FACTORS
Human leukocyte antigens (HLA) - regulate immune response used as a marker for
Aggressive periodontitis mainly HLA-A9 and HLA-B15.
Negative correlation between HLA-A2, HLA-A12 and localized aggressive
periodontitis (LAP) have been found.
Risk of disease is found in subjects with HLA-A9 and B15 positive individuals
which is about 1.5 to 3.5 times greater than those lacking theses antigens.
Alpan AL. Aggressive Periodontitis In: Periodontology and Dental implantology. 2018;103-129.
49. Functional defects of PMNs, monocytes, or both:-
Impair the chemotactic attraction of PMNs to the site
of infection or their ability to phagocytose & kill
microorganisms.
Hyperresponsiveness of monocytes from LAP
patients involving their production of PGE2 in
response to LPS.
Increased connective tissue or bone loss.
Alpan AL. Aggressive Periodontitis In: Periodontology and Dental implantology. 2018;103-129.
50. There are characteristic functional defects of polymorphonuclear
leucocytes with hyperesponsive monocytes.
Altered T helper or suppressor T-cell have also been studied.
Polyclonal activation of B-cell is seen by microbial plaque.
Schenkein et al have recently reported elevated Serum IL-17 levels in
GAgP. They Suggested “An altered systemic response to oral bacterial
antigens”.
Alpan AL. Aggressive Periodontitis In: Periodontology and Dental implantology. 2018;103-129.
51. DIAGNOSIS
Clinical diagnosis is based on information derived from a specific medical
and dental history and from the clinical examination of the periodontium.
The purpose of clinical diagnosis is the identification of patients suffering
from AgP and of factors that have an impact on how the case should be
treated and monitored.
Lang LP and Carring T. Aggressive periodontitis In: Lindhe’s Clinical periodontology and implant dentistry. Elsevier 5:438-460.
53. Clinical examination
probing pocket depth and
attachment loss
Radiological examination
Microbiological examination,
Evaluation of host response
Genetic susceptibility to diagnose AgP
Site specific destruction around incisors and molars is an important criteria to
diagnose LAP
Severe destruction around minimum no. of teeth or generalized moderate to severe
destruction in early age again indicates aggressive nature of disease.
54. Rate of bone loss in between two or more consecutive visits should be
carefully observed which can indicate the rapid rate of progression of
disease or active stage of disease.
Presence of any systemic disease like Neutropenia, Leucocyte adhesion
deficiency, Chidiak -Higashi disease should be ruled out.
Differential white blood cell count is important to rule out neutropenic
condition, in relation to confirm AgP.
Novak K F and Novak J M:Aggressive Periodontitis in Carranza’s clinical periodontology,Elsevier,12,2010;506-512.
55. Incidental attachment loss due to other causes like presence of impacted
tooth or tumor or orthodontic tooth movement or advance decay of tooth
should be ruled out.
Establishing the trace of familial aggregation of cases, on the basis of
history and clinical examination of family members can be done.
A common strategy employed to detect early disease is to closely
monitor high-risk patients such as the siblings.
Novak K F and Novak J M:Aggressive Periodontitis in Carranza’s clinical periodontology,Elsevier,12,2010;506-512.
56. MICROBIOLOGIC DIAGNOSIS
The international classification workshop indicated that the presence of
specific microorganisms like A.a. in particular represents one of the
secondary features of AgP.
As such, microbiological diagnosis may be a useful laboratory addition
to establish a differential diagnosis between aggressive and chronic
forms of periodontitis.
Lang LP and Carring T. Aggressive periodontitis In: Lindhe’s Clinical periodontology and implant dentistry. Elsevier 5:438-460.
57. Culture Methods
Only current method capable of determining the in vitro
antimicrobial susceptibility of periodontal pathogens.
Provide a quantitative measurement of all major
viable microorganisms in the specimen. Eg : Malachite
green bacitracin agar, TSBV agar
Saroch N. Periodontitis In: Periobasics A textbook of Periodontitis and implantology.2;2019:339-363.
58. Immunodiagnostic methods
It employs antibodies that recognize specific bacterial antigens to detect
target microorganism.
Advantages:
Do not require viable bacteria
Less susceptible to variations in sample processing
Less time consuming
Easier to perform than culture method
Saroch N. Periodontitis In: Periobasics A textbook of Periodontitis and implantology.2;2019:339-363.
59. Bonta et al (1985) described an indirect immunofluroscence identification
method of A.a. with a detection limit of 500 cells/ml, a sensitivity of 82 -
100% and a specificity of 88-92% compared with selective &
nonselective culture.
Evalusite test
Antibody based sandwich enzyme linked immunosorbent assay.
Bacterial concentration fluroscene immunoassay.
Monoclonal antibodies to whole cell antigens
Saroch N. Periodontitis In: Periobasics A textbook of Periodontitis and implantology.2;2019:339-363.
60. GENETIC DIAGNOSIS
Nucleic acid probe
DNA probes entails segments of single stranded nucleic acid, labeled
with an enzyme or radioisotope that can locate and bind to their
complementary nucleic acid sequences with low cross reactivity to non
target microorganism.
DNA probe may target whole genomic DNA or individual genes.
Saroch N. Periodontitis In: Periobasics A textbook of Periodontitis and implantology.2;2019:339-363.
62. PRINCIPLES OF THERAPEUTIC INTERVENTION
Treatment of Aggressive Periodontitis should only be initiated after
completion of a careful diagnosis.
Successful treatment of Aggressive Periodontitis is considered to be
dependent on
Early diagnosis
Therapy towards elimination or suppression of the infecting
microorganisms
Providing an environment conducive to long term maintenance.
Lang LP and Carring T. Aggressive periodontitis In: Lindhe’s Clinical periodontology and implant dentistry. Elsevier 5:438-460.
63. THERAPEUTIC MODALITIES
Early detection is critically important in the treatment of aggressive
periodontitis (generalized or localized) because preventing further
destruction is often more predictable than attempting to regenerate
lost supporting tissues.
Therefore, at the initial diagnosis, it is helpful to obtain any
previously taken radiographs to assess the rate of progression of
the disease.
Lang LP and Carring T. Aggressive periodontitis In: Lindhe’s Clinical periodontology and implant dentistry. Elsevier 5:438-460.
67. NON-SURGICAL THERAPY
Its effect on aggressive periodontitis is much less clear.
SRP reduced the total sub-gingival bacterial counts and the proportions of certain
gram negative bacteria, but no periodontal pocket became free of A.
Actinomycetemcomitans.
GAP responds well to SRP in the short term (upto 6months). However, after
6months, relapse and disease progression is reported.
Gunsolley et al
Haas et al, 2008
Sigusch et al, 1998
68. Nonsurgical therapy alone as a treatment of localized aggressive
periodontitis -
Slots & Rosling 1983, evaluated nonsurgical treatment alone in AgP.
Upon re-evaluation the combination of oral hygiene instructions along
with subgingival scaling and root planing did not eliminate, the
number of spirochetes, Aggregatibacter actinomycetemcomitans and
Capnocytophaga species but resulted in a small improvement in post-
treatment probing depths.
Saroch N. Periodontitis In: Periobasics A textbook of Periodontitis and implantology.2;2019:339-363.
69. Nonsurgical therapy alone as a treatment of
Generalized Aggressive Periodontitis
Purucker et al 2001 provided scaling and root planing for 30 patients
with generalized aggressive periodontitis. Two months after scaling
they found that the deepest sites in each quadrant experienced an
approximate 1 mm reduction in probing depth and a 0.5 mm gain in
attachment levels.
70. Antimicrobial Therapy
Systemic tetracycline (250 mg of tetracycline hydrochloride
4x/day for atleast 1 week) in conjunction with local mechanical
therapy.
Nutalapati R, Kasagani SK et al in 2014 , concluded that systemic
administration of doxycycline with full mouth SRP resulted in better
improvement of periodontal parameters and elimination of putative
periodontal pathogens such as A.a, P.g, T. forsythia, than amoxicillin plus
metronidazole alone in patients with LAP.
Nutalapati R et al. Comparative evaluation of amoxicillin plus metronidazole and doxycycline alone in the nonsurgical treatment of localized
aggressive periodontitis . Indian J Oral Sci 2014;5:112-8
71. If surgery is indicated, systemic TTC 1000mg stat should be
prescribed approximately 1 hour before surgery.
TTC resistant A.A - Amoxcillin-MTZ
Ciprofloxacin-MTZ
Doxycline, 100 mg/day, may be used instead of TTC.
Chlorhexidine rinses should be prescribed and continued for
several weeks to enhance plaque control and facilitate healing.
Nutalapati R et al. Comparative evaluation of amoxicillin plus metronidazole and doxycycline alone in the nonsurgical treatment of localized
aggressive periodontitis . Indian J Oral Sci 2014;5:112-8
72. Genco et al treated LAP patients with-
SRP+Systemic administration of TTC
(250mg q.i.d x 14days every 8weeks).
18mths
Bone loss stopped, 1/3rd of defects demonstrated an increase in bone level
Liljenberg and Lindhe treated LAP patients with
Systemic administration of TTC (250mg q.i.d for 2 weeks)
Modified Widman flap
Periodic recall visits (one visit every month for 6mnths, then one visit every 3 mnths)
The lesions healed more rapidly and more completely.
Saroch N. Periodontitis In: Periobasics A textbook of Periodontitis and implantology.2;2019:339-363.
73. In practice, antibiotics are often used empirically without
microbial testing.
Empiric use of antibiotics, such as a combination of amoxicillin &
MTZ, may be more clinically sound and cost-effective than
bacterial identification & antibiotic-sensitivity testing.

76. GENERALISEDAGGRESSIVE PERIODONTITIS
Sigusch et al (2001), Xajigeorgiou et al (2006), Guerrero at al
(2007) suggested use of Clindamycin + SRP showed increase in
clinical attachment gain and reduction in pocket depth.
Kaner et al (2007) showed use of MTZ/amoxicillin given
immediately after SRP will be more effective in resolving deep
sited in GAP patients.
Saroch N. Periodontitis In: Periobasics A textbook of Periodontitis and implantology.2;2019:339-363.
77. Local delivery agents including solutions, gels,
fibers, chips
Smaller dosages of topical agents can be delivered inside the
pocket.
Avoidance the side effects of systemic antibacterial agents.
Increases the exposure of the target microorganisms to higher
concentrations, of the medication.
78. Local drug delivery as an adjunct
Sakellari D et al 2003 reported that tetracycline fibers, in
conjunction with scaling and root planing, in patients with
generalized aggressive periodontitis was more effective than scaling
and root planing alone and can also be used in situations where
systemic antibiotics are contraindicated.
79. Full-Mouth Disinfection
Another approach to antimicrobial therapy
The concept, described by Quirynen et al, consists of ;-
Full mouth debridement completed in 2 appointments within a 24
hour period.
The tongue is brushed with a chlorhexidine gel (1%) for 1 minute.
Mouth rinsed with a chlorhexidine solution (0.2%) for 2minutes.
Periodontal pockets irrigated with a chlorhexidine solution. (!%)

80. Host Modulation
A novel approach in the treatment of AP and difficult to control
forms of periodontal disease.
Modulates the host response to disease.
TTCs
Growth factors
EMPs
BMPs
Bisphosphonates
NSAIDs

83. Surgical Resective Therapy
Effective to reduce or eliminate pocket depth
Difficult to accomplish if adjacent teeth are unaffected, (in cases
of LAP)
Careful evaluation of the risks versus the benefits of surgery must
be considered on a case-by-case basis.
Teughels W, Dhondt R, Dekeyser C & Quirynen M. Treatment of aggressive periodontitis Periodontology 2000; 2014, 65:107–133.
84. Regenerative Surgery
Bone grafting
• Guided tissue regeneration using membranes,
The use of biologic modifiers &
Combinations of the above
Designed for the regeneration of steep vertical defects & have very specific indications
:- defect morphology, tooth mobility & furcation involvement.
Alpan AL. Aggressive Periodontitis In: Periodontology and Dental implantology. 2018;103-129.
85. Bone grafting
Yukna & Sepe, reported on average defect fill of 80% with FDBA in 12
patients with LAP at re-entry after 12months.
Evans et al evaluated a 4:1 ratio combination of B-tricalcium phosphate/
TTC, hydroxyapatite/TTC or freeze-dried bone allograft/TTC in patients
with LAP which showed significant increase in defect depth & pocket
depth were detected for each graft material.
Hydroxyapatite/TTC > B-tricalcium phosphate/ TTC.

OF AP.
Effect of ozonized water on oral microorganisms & dental plaque was studied by
Nagayoshi et al., (2002).
Useful in reducing the infections caused by oral microorganisms in dental plaque.
Ramzy et al assessed the clinical and antimicrobial effect of ozonized water in
management of aggressive periodontitis, found that ozone has a potent
antibacterial effect explained by the fact that it causes disruption of the envelope
integrity through peroxidation of phospholipids.

91. Occlusal adjustment in case of tooth migration
In few cases after successful periodontal treatment and after the condition
has become fully stable, gentle orthodontic retraction of labially drifted
upper incisors might be considered if they can be stabilized behind the
lower lip or splinted in a stable position.
Prosthetics - for missing teeth after extraction of teeth with poor prognosis.
Maintenance - Patient should be recalled every 3 month for oral hygiene
reinforcement and scaling.
Alpan AL. Aggressive Periodontitis In: Periodontology and Dental implantology. 2018;103-129.
92. FUTURE DIRECTIONS
Genetic tests in Diagnosis of Aggressive Periodontitis.
Use of host modulation therapy.
Periodontal vaccines.
93. PERIODONTAL MAINTENANCE
The duration between recall visits should be usually short during the
period after completion of therapy, generally no longer than 3-month
intervals.
Monitoring as frequently as every 3-4 weeks may be necessary when the
disease is thought to be active.
If signs of disease activity and progression persist despite therapeutic
efforts, frequent visits and good patient compliance, microbial testing
may be indicated.
94. CONCLUSION
AgP is definitely a different entity than commonly present chronic
periodontitis. Quality of plaque i.e. specific micro organisms seems to be
responsible for severe periodontal destruction. Susceptibility of individuals is
further determined by genetic, environmental and host immune factor.
Phase I therapy is mandatory in controlling the infection and antibiotics act as
adjuvant to it. Periodontal surgical therapy has definitely given positive
results.
Thus a thorough examination leading to accurate diagnosis and subsequent
comprehensive treatment is the supreme responsibility.
