<unk>  is defined as the enlargement of pulp chambers with the furcation area being displaced toward the apex of the root. It cannot be diagnosed clinically and requires radiographic visualization since the crown of a taurodontic tooth appears normal and its distinguishing features are present below the alveolar margin.<unk>  can present in deciduous or permanent dentition, unilaterally or bilaterally, but is most common in the permanent molar teeth of humans. The underlying mechanism of<unk>  is the failure or late invagination of Hertwig's epithelial root sheath, which leads an apical shift of the root furcation.
