Periodontics · single question

Gingival biotypes (phenotypes) are conventionally classified as:

  1. Thin, thick, and average
  2. Type I and Type II only
  3. Acute and chronic
  4. Keratinized and non-keratinized
Show answer and explanation

Correct answer: A. Thin, thick, and average

  • A. Correct. Gingival biotype is described as thin (scalloped, delicate), thick (flat, fibrotic), or average, which guides esthetic and surgical risk assessment.
  • B. Incorrect. 'Type I/II' is not the standard biotype terminology.
  • C. Incorrect. Acute/chronic describes inflammation timing, not biotype.
  • D. Incorrect. Keratinized vs non-keratinized describes tissue type, not the thin/thick biotype scheme.
