Read the first 7 Periodontics and Gum Health flashcards as text

  1. Which parameter is used in the 2017 AAP/EFP staging and grading system to indicate rate of periodontitis progression?

    Answer: Grade (A–C)

    Grade (A = slow, B = moderate, C = rapid) reflects the rate of periodontitis progression based on direct and indirect evidence.

  2. Enamel projections and enamel pearls are significant in periodontal disease because they:

    Answer: Preclude connective tissue attachment, facilitating furcation involvement

    Enamel projections extending toward furcations prevent normal periodontal fiber attachment, making those areas susceptible to furcation disease.

  3. A patient with well-controlled Type 1 diabetes and Stage III periodontitis is classified as Grade:

    Answer: Grade B

    Well-controlled diabetes is a grade modifier that upgrades the patient to at least Grade B due to the systemic risk factor.

  4. Which radiographic bone pattern is MOST favorable for periodontal regeneration?

    Answer: Three-wall infrabony defect

    Three-wall infrabony defects provide three bony walls to support regenerative materials and act as a scaffold, yielding the best regenerative outcomes.

  5. Gingival hyperplasia is a known side effect of all of the following medications EXCEPT:

    Answer: Metformin

    Metformin (an antidiabetic drug) does not cause gingival enlargement; phenytoin, cyclosporine, and calcium channel blockers like nifedipine are the classic culprits.

  6. The modified Widman flap differs from an open flap debridement primarily because it:

    Answer: Includes a reverse bevel incision and removes the inner epithelium and granulation tissue

    The modified Widman flap uses a reverse bevel (internal bevel) incision to excise the pocket epithelium and inflamed connective tissue while preserving the outer gingival tissue.

  7. Which measurement defines the width of attached gingiva?

    Answer: Distance from mucogingival junction to bottom of pocket subtracted from total gingival width

    Attached gingiva width = total keratinized tissue width (free gingival margin to MGJ) minus the probing depth.
