Which cytokine is primarily responsible for bone resorption in periodontal disease?
Answer: Interleukin-1β
IL-1β is a key pro-inflammatory cytokine that stimulates osteoclast activity and drives alveolar bone resorption in periodontal disease.
A patient presents with 5–6 mm pockets and horizontal bone loss. Which classification stage best describes this presentation?
Answer: Stage II
Stage II periodontitis features probing depths of 5–6 mm with horizontal bone loss up to one-third of root length.
The junctional epithelium attaches to the tooth surface via which structure?
Answer: Hemidesmosomes and basal lamina
Junctional epithelium attaches to enamel and cementum through hemidesmosomes combined with an internal basal lamina.
Which organism is most associated with aggressive (Grade C) periodontitis in young patients?
Answer: Aggregatibacter actinomycetemcomitans
Aggregatibacter actinomycetemcomitans (Aa) produces leukotoxin and is the primary pathogen associated with Grade C periodontitis in adolescents.
Which type of gingival fiber group runs from the cementum coronally to the free gingiva?
Answer: Dentogingival
Dentogingival fibers extend from the cervical cementum outward and coronally into the free and attached gingiva.
Gingival recession classified as Cairo RT2 indicates:
Answer: Loss of interproximal attachment less than buccal attachment loss
Cairo RT2 recession has interproximal CAL loss that is less than the buccal CAL loss, distinguishing it from RT3.
Which mucogingival procedure uses a palatal connective tissue graft placed under a split-thickness flap to increase keratinized tissue width?
Answer: Subepithelial connective tissue graft
The subepithelial connective tissue graft (Langer technique) places harvested palatal CT under a partial-thickness recipient flap for root coverage and tissue augmentation.
