Taurodontia is characterized by which feature?

• A. Elongated pulp chamber with short roots
• B. Short pulp chamber with elongated roots
• C. Normal pulp chamber
• D. Increased root dentin thickness

Answer: (A)

Taurodontia is a dental anomaly where the tooth’s body is enlarged and the pulp chamber becomes elongated, with the roots being relatively short. On X‑rays the pulp chamber appears tall and the pulpal floor is displaced toward the apex, with the furcation located more apically than normal. This combination—an elongated pulp chamber with short roots—describes taurodontia precisely, making it the best fit for the option that states this pattern. The other descriptions do not match this characteristic arrangement: a short pulp chamber with elongated roots reverses the hallmark, a normal pulp chamber lacks the change, and increased root dentin thickness is not the defining feature of taurodontia.
