Local Predisposing Factors Most important predisposing factors are: i. Pre-existing gingivitis ii. Injury to the gingiva iii. Smoking Systemic Predisposing Factors ►Nutritional deficiency ►Debilitating diseases ►Psychosomatic factors activation of the hypothalamic pituitary adrenal axis ↑ cor�sol levels ↓ lymphocyte and polymorphonuclear leukocytes func�on


Relationship of Bacteria to the Characteristic Lesions four zones 1. Zone I—Bacterial zone: It is the most superficial zone, consists of varied bacteria, including a few Spirochetes of the small, medium-sized and large types. 2. Zone II—Neutrophil-rich zone: Contains numerous leukocytes predominantly neutrophils with bacteria including spirochetes of various types. 3. Zone III—Necrotic zone: Consists of a dead tissue cells, remnants of connective tissue fragments, and numerous spirochetes. 4. Zone IV—Zone of spirochetal infiltration: Consists of a well preserved tissue infiltrated with spirochetes of intermediate and large-sized without other organisms.


Treatment Treatment for Non-ambulatory Patients Day 1: a. gently removing the necrotic pseudomembrane with a pellet of cotton saturated with hydrogen peroxide (H2O2). b. Advised bed rest and rinse the mouth every 2 hours with a diluted 3 percent hydrogen peroxide (H2O2). c. Systemic antibiotics like penicillin or metronidazole can be prescribed.


Day 2: After 24 hours, a bedside visit should be made. The treatment again includes gently swab the area with hydrogen peroxide, instructions of the previous day are repeated. Day 3: Most cases, the condition will be improved, start the treatment for ambulatory patients.


Treatment for Ambulatory Patients First visit: ►topical anesthetic ►gently swabbed with a cotton pellet to remove pseudomembrane and non-attached surface debris. ►area is cleansed with warm water ►superficial calculus is removed with ultrasonic scalers. ►Antibiotics prescription ►Subgingival scaling and curettage are contraindicated Instructions to the patient 1. Avoid smoking and alcohol. 2. Rinse with 3 percent hydrogen peroxide and warm water for every two hours. 3. Confine toothbrushing to the removal of surface debris with a bland dentifrice, use of interdental aids and chlorhexidine mouth rinse are recommended.


Second visit: ►Scalers and curettes are added to the instrumentarium. ►Shrinkage of the gingiva may expose previously covered calculus which is gently removed. ►Same instructions are reinforced. Third visit: ►Scaling and root planing are repeated, ►Plaque control instructions are given. ►Hydrogen peroxide rinses are discontinued. Fourth visit: ►Oral hygiene instructions are reinforced ►thorough scaling and root planing are performed.


Fifth visit: ►Appointments are fixed for treatment of chronic gingivitis, periodontal pockets and pericoronal flaps, and for the elimination of all local irritants. ►Patient is placed on maintenance program. Further Treatment Considerations 1. Gingivoplasty. 2. Systemic antibiotics—only in patients with toxic systemic complications. 3. Supportive systemic treatment—copious fluid consumption and administration of analgesics and adequate bed rest. 4. Nutritional supplements—vitamin B/C supplements.


ACUTE HERPETIC GINGIVOSTOMATITIS (AHG) ►viral infection of the oral mucous membrane caused by HSV I and II ►occurs most frequently in infants and children younger than 6 years of age but is also seen in adults. Clinical Features 1. appears as a diffuse, shiny erythematous, involvement of the gingiva and the adjacent oral mucosa with varying degrees of edema and gingival bleeding. 2. In its initial stage it may appear as discrete, spherical, clusters of vesicles dispersed in different areas, e.g. labial and buccal mucosa, hard palate, pharynx and tongue. After approximately 24 hours the vesicles rupture and form painful shallow ulcers with scalloped borders and surrounding erythema.

Oral Symptoms 1. Generalized soreness of the oral cavity which interferes with eating and drinking. 2. The ruptured vesicles are sensitive to touch, thermal changes and food.

d Systemic Signs and Symptoms

After the primary infection the virus remains latent in the nerve tissue. If reactivation occurs it causes Herpes labialis (cold sore).

It is associated with prodrome of tingling and itching on the corners of lip followed by formation and ulceration

Recurrent Aphthous Stomatitis (RAS)

common condition which is characterized by recurrent small, round or ovoid ulcers with circumscribed

, and yellow or gray floors typically presenting first in childhood or adolescence

The lesions may occur anywhere in the oral cavity, the buccal and labial

lesion and may occur as a single lesion or as lesions throughout the mouth

recurrent small, round or ovoid ulcers with circumscribed margins,

buccal and labial mucosae


Types Minor aphthae: ►Is the most common affecting about 80% of patients with RAS ►ulcers are round or oval usually <5 mm in diameter with a gray-white pseudomembrane and an erythematous halo. ►The ulcers heal within 10-14 days without scarring. Major aphthae: ►Is a rare severe form of Aphthous ulcer. ►Ulcers are oval and may exceed 1 cm in diameter. ►Ulcers persist for up to 6 weeks and often heal with scarring.


Herpetiform aphthae: ►least common variety ►characterized by multiple recurrent crops of widespread small, painful ulcers. ►As many as 100 ulcers may be present at a given time, ►each measuring 2-3 mm in diameter.


Etiology ►Unknown ►linked to RAS are genetic predisposition, ►Hematinic deficiencies, ►Immunologic abnormalities, ►stress, ►food allergy ►gastrointestinal disorders. ►Predisposing factors include hormonal disturbances, trauma, cessation of smoking and menstruation Treatment ►topical lignocaine ►Topical steroids like Triamcinolone and Clobetasol ►systemic steroids and Thalidomide to reduce the number of ulcers and recurrences.

PERICORONITIS

acute infection which refers to inflammation of of an incompletely erupted tooth.

It occurs most frequently in the mandibular Types

Acute,

subacute or chronic

acute infection which refers to inflammation of gingiva and surrounding soft tissues erupted tooth.

It occurs most frequently in the mandibular third molar area.

Page 21

gingiva and surrounding soft tissues


Signs and Symptoms

markedly red, edematous suppurating lesion that is extremely tender with radiating pain to the ear, throat and floor of the mouth

foul taste and inability to close the jaws.

swelling of the cheek

interferes with complete jaw closure

flap is traumatized by contact with the opposing jaw and inflammatory involvement is aggravated.

toxic systemic complications such as fever, leukocytosis and malaise


Complications

Localized pericoronal abscess or cyst formation

may spread posteriorly into the oropharyngeal area and medially into the base of the tongue, making it difficult for the patient to swallow Peritonsillar abscess formation, cellulitis and Ludwig’s angina are the potential complications Treatment The treatment of pericoronitis depends on:

• Severity of the inflammation.

• The systemic complications, and

• The advisability of retaining the involved tooth


First Visit

warm water flush + topical anesthetic agent

flap is reflected with a scaler and the underlying debris is also removed

hourly rinses instructions

copious fluid intake

systemic antibiotics

If the gingival flap is swollen and fluctuant an antero-posterior incision to establish drainage is made with a No. 15 bard parker blade

followed by insertion of 1/4th inch gauze wick

In the next visit, determination is made as to whether the tooth is to be retained or extracted
