Periodontal probing depth is measured from the:
Answer: Gingival margin to the base of the pocket
Probing depth is the distance from the free gingival margin to the base of the periodontal pocket or sulcus.
Which bacteria is most strongly associated with adult chronic periodontitis?
Answer: Porphyromonas gingivalis
Porphyromonas gingivalis is a keystone pathogen in chronic periodontitis, producing virulence factors including gingipains that disrupt the host immune response.
The biologic width refers to the combined measurement of:
Answer: Junctional epithelium and connective tissue attachment above the alveolar crest
The biologic width (~2.04 mm) consists of the junctional epithelium (~0.97 mm) and supracrestal connective tissue attachment (~1.07 mm) above the alveolar bone crest.
Which furcation classification indicates that the furcation can be completely probed through from one side to the other?
Answer: Class III
Class III (through-and-through) furcation involvement means the probe passes completely through the furcation from the buccal to lingual/palatal surface.
Aggressive periodontitis in young patients is most commonly associated with which organism?
Answer: Aggregatibacter actinomycetemcomitans
Aggregatibacter actinomycetemcomitans (Aa) is strongly associated with localized aggressive periodontitis, particularly in adolescents and young adults.
Which systemic condition is most strongly associated with an increased risk of periodontitis?
Answer: Type 2 diabetes mellitus
Type 2 diabetes mellitus significantly increases the risk and severity of periodontitis through impaired neutrophil function, advanced glycation end-products, and altered wound healing.
