Endodontics · single question

All of the following characterize taurodontism EXCEPT:

  1. Short roots with normal crown morphology
  2. Occlusally displaced furcation
  3. Enlarged, rectangular pulp chamber
  4. Apically displaced furcation
Show answer and explanation

Correct answer: B. Occlusally displaced furcation

  • A. True — the roots are correspondingly short, and the external crown looks clinically normal (diagnosis is radiographic).
  • B. Correct. Taurodontism is defined by an APICALLY displaced furcation — the opposite of this option. The crown-to-furcation distance is increased, not decreased.
  • C. True — the pulp chamber is vertically enlarged and rectangular, extending well below the CEJ.
  • D. True — the furcation is shifted apically, producing the elongated 'bull-tooth' body.
