Abstract

The present investigation utilized the Bolton Analysis to determine the incidence and magnitude of tooth-size discrepancy in a sample of 227 orthodontic patients. Sliding calipers were used to measure the mesiodistal width of the permanent dentition on pretreatment study models of 120 Caucasian, 51 Black, and 56 Hispanic patients. The overall and anterior ratios were analyzed and the frequency and magnitude of excess maxillary and mandibular tooth structure was determined. Each racial group demonstrated a significant incidence of tooth-size discrepancy in the maxillary and mandibular arches of a magnitude (> 0.5mm) which would require some form of correction. In addition, one-way analysis of variance revealed the mean overall ratio for Blacks was significantly different than the mean overall ratio for Caucasians and Hispanics.

Key words: Bolton Analysis, tooth-size discrepancy, tooth-size analysis, mesiodistal width, dental biometrics
