Which statement about taurodontism is NOT true?

Correct answer: C. The furcation is displaced occlusally

• A. ❌ True. Because the furcation is apically placed, the roots themselves are correspondingly short.
• B. ❌ True. The vertically enlarged pulp chamber is the defining feature and is what makes endodontic access and working length determination difficult.
• C. ✅ CORRECT — This is the FALSE statement. In taurodontism the furcation is displaced APICALLY, not occlusally. Failure of Hertwig epithelial root sheath to invaginate at the proper level moves the bifurcation toward the apex, producing the elongated 'bull tooth' body.
• D. ❌ True. Taurodontism occurs in isolation and in syndromes including Klinefelter, Down, amelogenesis imperfecta and tricho-dento-osseous syndrome.
