Taurodontism in Down's syndrome

Abstract

Forty-three pantograms of the subjects with Down's syndrome were examined for the diagnosis of taurodontic teeth, grade of taurodontism, sex distribution and individual tooth involvement. Taurodontic teeth were found in 55.8% of the subjects, 32.6% females and 23.2% males. Second molars were most frequently affected (53.2%), followed by first molars (40%) and third molars (6.5%). The mesotaurodontic form was the most frequent form of the anomalia (72.5%). Hyypotaurodontic teeth were observed in 9.7% and pyramidal teeth in 17.7% of the cases. Hypertaurodontic teeth were not found.
