Tooth size and morphology in hemifacial microsomia

Abstract

To determine whether tooth size and morphology are affected in HFM. The mesiodistal diameter of each tooth of 40 patients with varying severity of HFM was measured with a vernier gauge calibrated to 0.1 mm. Data obtained from teeth on the affected side were compared with data from corresponding teeth on the contralateral side. Center for Craniofacial Anomalies, School of Dentistry, University of California, San Francisco, USA. Subjects with HFM have smaller teeth on the affected side than on the contralateral side. The more severely affected subjects have the highest degree of tooth size asymmetry. Tooth morphology is also affected in individuals with HFM.
