Periodontics · single question

Among potential sites for periodontal regenerative procedures, which is generally considered the most favorable?

  1. A mesial defect on a canine
  2. A furcation defect on a molar
  3. A defect on a tooth with minimal remaining attachment
  4. Any posterior tooth defect regardless of anatomy
Show answer and explanation

Correct answer: A. A mesial defect on a canine

A mesial defect on a canine is generally considered a favorable site for periodontal regeneration, given the canine's relatively simple, single, broad root anatomy with good vascularity and the absence of furcation involvement concerns — in contrast to molar furcation defects, which present more anatomically complex challenges for regenerative success.
