Which of the following statements about taurodontism is true?

Taurodontism is characterized by the anatomical alteration of teeth, specifically involving significant elongation of the pulp chamber and the presence of a wider apical region, which resembles a bull's shape, hence the name derived from "tauro," meaning bull. In taurodont teeth, the pulp chamber becomes enlarged and extends vertically into the root, creating a unique morphology that distinguishes these teeth from normal ones.

The condition is primarily noted in molars and can be observed in various populations, sometimes linked to genetic factors or associated syndromes. The defining feature of taurodontism is indeed the "bull-like extensions" of the pulp chamber, making this statement accurate.

Other aspects of taurodontism, such as the shapes of the roots or how the teeth relate to each other, do not align with the defining characteristics of taurodontism. The anatomical modifications do not frequently lead to transposition (incorrect positioning of teeth), nor is it directly related to congenital tooth absence, which refers to cases where teeth do not develop at all. Thus, the focus on the unique pulp chamber formation in option C accurately reflects the essence of taurodontism.
