Read the first 7 Periodontics and Gum Health flashcards as text

  1. Which systemic condition is MOST strongly associated with necrotizing periodontal disease in a young adult?

    Answer: HIV/AIDS

    HIV/AIDS causes profound immunosuppression that predisposes patients to necrotizing ulcerative gingivitis and periodontitis.

  2. The biologic width consists of which two components?

    Answer: Junctional epithelium and connective tissue attachment

    Biologic width (~2 mm) comprises the junctional epithelium (~1 mm) and supracrestal connective tissue attachment (~1 mm) above the alveolar crest.

  3. A furcation involvement where a probe penetrates into the furcation but does not pass through to the other side is classified as:

    Answer: Class II

    Hamp's Class II furcation involvement means the horizontal loss of attachment exceeds 3 mm but does not pass through the furcation.

  4. Which antibiotic regimen is most appropriate as an adjunct to scaling and root planing for aggressive periodontitis caused by Aa?

    Answer: Amoxicillin 500 mg + Metronidazole 250 mg TID for 7 days

    The amoxicillin-metronidazole combination targets Aa effectively and is the evidence-based adjunct for aggressive periodontitis.

  5. During periodontal flap surgery, the term 'osseous recontouring' refers to:

    Answer: Reshaping alveolar bone to eliminate osseous defects and craters

    Osseous recontouring (osteoplasty/ostectomy) reshapes the alveolar bone to create positive architecture and eliminate infrabony defects.

  6. Which local drug delivery agent releases chlorhexidine and is placed directly into periodontal pockets as an adjunct therapy?

    Answer: PerioChip (chlorhexidine gluconate chip)

    PerioChip is a biodegradable chip containing 2.5 mg chlorhexidine gluconate placed into pockets ≥5 mm as adjunctive therapy.

  7. The 'red complex' bacteria in periodontal disease includes Porphyromonas gingivalis, Treponema denticola, and which third organism?

    Answer: Tannerella forsythia

    Socransky's red complex consists of P. gingivalis, T. denticola, and Tannerella forsythia, strongly associated with severe periodontitis.
