This document discusses various root coverage procedures for treating gingival recession. It begins by defining gingival recession and classifying types. Nonsurgical treatments including monitoring, desensitizing agents, and restorations are outlined. Surgical options such as laterally positioned flaps, double papilla flaps, coronally positioned flaps, free gingival grafts, and subepithelial connective tissue grafts are described in detail. Factors in selecting a procedure and modifications to techniques are also summarized. The document concludes that careful case selection and surgical management are key to achieving successful root coverage outcomes.
Phase I periodontal therapy is the first in the chronologic sequence of procedures that constitute periodontal treatment. It is also referred to as cause related therapy or non-surgical periodontal therapy.
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.

In periodontology, classifications are widely used to categorize defects due to periodontitis according to their etiology, diagnosis, treatment and prognosis.
Several classifications have been proposed in the literature in order to facilitate the diagnosis of gingival recessions.
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 complex infection initiated by bacteria –tissue destruction.
Host: the organism from which a parasite obtains its nourishment/ an individual who receives a graft
Modulation: the alteration of function or status of something in response to a stimulus or an altered physical or chemical environment
Certains medications have been associated with gingival enlargement.

Periodontal plastic surgery is defined as the surgical procedures performed to correct deformities of the gingiva or alveolar mucosa. It includes widening of attached gingiva,
deepening of shallow vestibules, resection of the aberrant frena, depigmentation of gingiva.In all of these procedures, blood supply is the most significant concern and must be the underlying issue for all decisions regarding the individual surgical procedure.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

How to Make a Field invisible in Odoo 17Celine George
It is possible to hide or invisible some fields in odoo. Commonly using “invisible” attribute in the field definition to invisible the fields. This slide will show how to make a field invisible in odoo 17.
We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

3. Definition
GINGIVAL RECESSION-
Gingival recession is defined as the
apical migration of the junctional epithelium
with exposure of root surfaces. [Kassab MM, Cohen RE-2003].
Gingival recession is the apical shift
of the marginal gingiva from
its normal position on the
crown of the tooth to levels on the root surface beyond the
cemento enamel junction [Loe H-1992].
4. Free Gingival Graft (FGG) - A soft tissue graft that is completely detached
from one site and transferred to a remote site. No connection with the
donor site is maintained
5. Sub-epithelial Connective Tissue Graft (CTG) - A detached connective tissue
graft that is placed beneath a partial thickness flap. This variation of the free
gingival graft provides the tissue graft with a nutrient supply on two surfaces
12. Non –surgical Treatment
Monitoring and prevention
Use of de-sensitizing agents, varnishes
Composite restoration
Removable gingival veneers
Orthodontics
13. Monitoring and prevention
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.
17. Orthodontics
In some cases surgical intervention and grafting may help to treat the
recession defect; however, if orthodontic treatment is an option that the
patient is willing to consider then any surgical intervention should be delayed
until after orthodontic tooth movement has been completed.
18. Indications For Surgical Intervention
The need to improve soft tissue aesthetics
Reduce hypersensitivity
Improve plaque control
Prevent further progression of recession defect
19. Key factors in the selection of surgical
procedures
RECIPIENT SITE
Gingival recession is limited to one tooth or extends to multiple teeth
Degree of gingival recession
Amount and thickness of existing keratinized gingiva in the area of
recession
20. Whether the area of recession protrudes labially from the dental arch
Restorative/Prosthodontic treatment after root coverage is necessary
21. Donor site
Whether area adjacent to gingival recession can be used as a donor site.
Amount of Keratinized gingiva
Thickness of keratinized gingiva
22. Size of adjacent interdental papilla
Thickness of the alveolar bone covering the donor tissue
Thickness of palatal soft tissue used as donor tissue
23. if adequate width is present at
the donor site the following
procedures can be selected:
a. Laterally (horizontally) displaced flap.
b. Double-papilla flap.
c. Coronally-positioned flap
If the donor site is associated
with inadequate width:
Free soft tissue auto graft
Sub epithelial connective tissue grafts
are available
Depending on the width of the attached gingiva
28. Laterally Positioned flap
Advantages
a. One surgical site
b. Good vascularity of the pedicle flap.
c. Ability to cover isolated, denuded roots that have adequate donor tissue
laterally.
29. Disadvantages
a. Limited by the amount of adjacent keratinized attached gingiva.
b. Possibility of recession at the donor site.
c. Dehiscence or fenestration at the donor site.
d. Limited to one or two teeth with gingival recession.
30. Indications:
a. For covering the isolated denuded root.
b. When there is sufficient width of interdental papilla in the adjacent teeth,
and Sufficient vestibular depth.
Contraindications:
a. Presence of deep interproximal pockets.
b. Excessive root prominence.
c. Deep or extensive root abrasion or erosion.
36. Double papilla flap
Indications:
1. When the interproximal papillae adjacent to the mucogingival problem are
sufficiently wide.
2. When the attached gingiva on an approximating tooth is insufficient to
allow for a Lateral Pedicle Flap.
Advantages:
1. The risk of loss of alveolar bone is minimized because the interdental bone
is more resistant to loss than is radicular bone.
2. The papillae usually supply a greater width of attached gingiva than from
the radicular surface of a tooth.
37.
38. Coronally positioned flap
Indications:
• Esthetic coverage of exposed roots.
• For tooth sensitivity owing to gingival recession.
Advantages:
• Treatment of multiple areas of root exposure.
• No need for involvement of adjacent teeth.
• High degree of success.
• Even if the procedure does not work, it does not increase the existing
problem.
40. Step 3: Return the flap and suture it coronal to the pretreatment position.
Step 4: Cover the area with a periodontal dressing.
41. Second Technique (Semilunar flap)
Indication:
Small localized area
Advantages:
• No vestibular shortening, as occurs with the coronally positioned flap.
• No esthetic compromise of interproximal papillae.
• No need for sutures.
42. Disadvantages:
• Inability to treat large areas of gingival recession.
• The need for a free gingival graft if there is an underlying dehiscence or
fenestration.
43. Step 1: Semilunar incision is made and ending about 2 to 3 mm short of the
tip of the papillae.
44. Step 2: Perform a split-thickness dissection coronally from the incision, and
connect it to an intrasulcular incision.
45. Step 3: The tissue will collapse coronally, covering the denuded root. then
held in its new position for a few minutes with a moist gauze. Many cases
do not require either sutures or periodontal dressing.
46. Double Lateral sliding bridge flap
Multiple gingival recession with or without adequate attached gingiva
Coronally
advanced

47.
48. Reasons for pedicle flap failure
Narrow
Flap
Tension

stabilization
49. Free Gingival Autograft
that consist of epithelium and a thin layer of underlying CT completely
detached from one site and transferred to a remote site.
Advantages
Increase keratinized tissue around teeth, implants or crowns and under
removable prostheses.
Increase vestibular depth.
50. Surgi cal Technique
Step 1: Prepare the recipient site.
Step 2: Root preparation:
Root planing of exposed root to remove cementum and affected dentin.
Etch root surface with tetracycline (pH 2.0).
51. Step 3: Obtain the graft from the donor site:
The ideal thickness of a graft is 1.0 - 1.5 mm.
52. Step 4: Graft transferred to recipient site.
Step 5: Protect the donor site.
53. Sub-epithelial Connective Tissue Graft
Indications:
• Where esthetics is of prime concern
• For covering multiple denuded roots
• In the absence of sufficient width of attached gingiva in the adjacent areas.
Advantages:
• High degree of cosmetic enhancement
• Incurs no additional cost for autogenous donor tissue
• Minimal palatal trauma
• Increased graft vascularity.
55. I. Preparation of recipient site:
The initial horizontal right angle incision is made into the adjacent
interdental papillae at, or slightly coronal to the cementoenamel junction of
the tooth with an exposed root surface. preserve the papillary blood
supply A partial thickness flap is raised without vertical incisions
SRP Root Conditioning with citric acid pH 1.0 or tetracycline HCl in a
concentration of 250 mg mixed in 5 ml of sterile water approximate
mesio distal width necessary for the graft is measured with a periodontal
probe.
56.
57. II. Excision of the donor tissue
1st incision horizontal incision 2-3mm apical to gingival margin
2nd incision parallel to the long axis of the teeth, 1 to 2 mm apical to the
first incision raise a full thickness periosteal connective tissue graft
62. Guided Tissue Regeneration
Indications
• Esthetic demand.
• Indicated for single tooth with wide, deep localized recessions.
• For areas of root sensitivity where oral hygiene is impaired.
• For repair of recessions associated with failing or unesthetic class V
restorations.
63. Advantages:
• Techniques does not require a secondary donor surgical site reducing
postoperative discomfort.
• New tissue blends evenly with the adjacent tissue, providing highly esthetic
results.
Disadvantages:
• It is sensitive technique.
• Insurance of additional cost of barrier membrane.
64. Step 1: A full-thickness flap is reflected to MGJ, continuing as a partial-
thickness flap 8 mm apical to MGJ.
Step 2: Root preparation.
65. Step 3: A membrane is placed over the root surface and the adjacent tissue
at least 2 mm of marginal periosteum.
Step 4: The flap is then positioned coronally and sutured.
66. The use of Allografts and Xenografts in
management
systematic review concluded that these grafts may be useful in situations
where
1- A large recession defect needs to be treated .
2- Graft tissue harvested from the palate would provide an insufficient
volume of tissue.
68. Criteria of successful root coverage
The gingival margin is on the CEJ in class I, Class II.
The depth of gingival sulcus is within 2mm.
There is no bleeding on probing , hypersensitivity.
Color match with adjacent tissue
69. Conclusion
The management of gingival recession and its sequelae is based on a thorough
assessment of the etiological factors and the degree of involvement of the
tissues. The initial part of the management of the patient with gingival recession
should be preventive and any pain should be managed and disease should be
treated.
The degree of gingival recession should be monitored for signs of further
progression. When esthetics is the priority and periodontal health is good then
surgical root coverage is a potentially useful therapy.
Numerous therapeutic solutions for recession defects have been proposed in
the periodontal literature and modified with time according to the evolution of
clinical knowledge.
70. The subepithelial connective tissue graft with a cornonally advanced flap is
gold standard grafting procedure .
Prognosis (amount of root coverage achieved) will depend on the severity
(size )of recession .
Careful case selection and surgical management are critical if a successful
outcome is to be achieved.
