DENT3060 Lecture Notes - Lecture 12: Periodontal Abscess, Pericoronitis, Dental Plaque
Document Summary
Dental-plaque induced gingival diseases: associated with dental plaque only (with/out local contributing factors, modified by systemic factors (endocrine, blood dyscrasias, modified by medications (drug-influenced, modified by malnutrition (ascorbic acid-deficiency) Localised: circumpubertal onset, 1st molar/incisor presentation with interproximal attachment loss on >2 other teeth robust serum antibody response to infecting agents. <30yo: poor serum antibody response to infecting agents, pronounced episodic nature of destruction of attachment & alveolar bone, generalised interproximal attachment loss >3 other teeth than 1st molar/incisors. Common features: pt otherwise healthy, microbial deposits inconsistent with severity, phagocyte abnormalities, hyperresponsive rapid attachment loss & bone destruction familial aggregation macrophage, attachment/bone loss progression self arresting. Localised tooth-related factors that modify/predispose to plaque-induced gingival diseases/periodontitis tooth anatomic factors: dental restorations/appliances, cergical root resorption & cemental tears root fractures. Mucogingival deformities & conditions around teeth: gingival/soft tissue recession (facial/lingual surfaces, interproximal) lack of keratinised gingiva, decreased vestibular depth, aberrant frenum/muscle position, gingival excess (pseudopocket, inconsistent margin, excessive display, enlargement, abnormal colour.
