Ch 9

sudden onset and rapid course of progression frequently accompanied with pain, localized or generalized, may be systemic

acute conditions

T or F: acute periodontal conditions are related to the presence of pre-existing gingivitis and or periodontitis

false

acute infection involving a localized collection of pus within the gingival wall of the periodontal pocket, circumscribed, containing pus

periodontal abscess

• acute or chronic (chronic usually no pain involved)

• difficulty masticating

• bad taste in mouth

• circumscribed localized edema

• possible tooth mobility

charcateristics of periodontal abscess

The associated tooth with the abscess is usually a vital pulp, therefore

not an endodontic abscess

What can cause abscesses in the periodontium

• blockage of the opening of an existing periodontal pocket

• forcing an object like a toothpick into the tissue

• incomplete calculus removal

What happens when we do not completely removal the calculus in the pocket

bacterial toxins are trapped and leads to an abscess

Treatment of pericoronal abscess

• local anesthesia

• drain pus

• irrigate

• antibiotics

• warm saline rinses

  • evaluate for 3rd molar extraction

acute infections of the periodontal tissues that involve necrosis

necrotizing periodontal diseases

Characteristics of NPD

necrosis, ulceration, pseudomembrane, punched out papillae

acute infection with necrosis and ulceration of the periodontium but only limited to gingival tissues

NUG

Another name for NUG

trench mouth

Examples of impaired host response associated with NUG

poor nutrition, fatigue, stress, systemic disease, alcohol abuse, drug abuse, immunosuppressive diseases

What bacteria associated with NUG?

gram-negative

Characteristics of NUG

• pain

• punched out papillae

• sloughing of pseudomembrane

• bleeding

• halitosis

Treatment of patient with NUG 1ST APPT

• gentle removal of pseudomembrane

• limited suprag instrumentation

• soft toothbrushing

• chlorahexidine rinses 2x daily

Treatment of patient with NUG 2ND APPT

• 2 days after initial

• subgingival instrumentation

• smoking cessation

• stress reduction

Treatment of patient with NUG 3RD APPT

• 5 days after initial

• complete subgingival instrumentation

  • antibiotics may be necessary

similar to NUG but affects the bone, can be accompanied by the formation of sequestrum (fragments of necrotic bone)

NUP

NUP requires

immediate referral to periodontist

rare condition, more severe, associated with immunocompromised patients, bone denudation in alveolar mucosa

necrotizing stomatitis

Necrotizing stomatitis requires

immediate consultation and referral to oral pathologist, oral maxillofacial surgeon, and physician

painful oral condition that results from the infection with herpes simplex virus HSV

primary herpetic gingivostomatitis

primary herpetic gingivostomatitis usually occurs in

infants or children less than 6yrs old

Primary herpetic gingivostomatitis is usually caused by initial infection with

HSV I

When are HSV conditions contagious

during vesicular stage through direct contact
