Cluster analysis of tooth size in subjects with normal occlusion.
INTRODUCTION Tooth-size studies are important in orthodontics. Our aim in this study was to establish normative data on tooth size with a clustering method. METHODS Dental casts of 307 subjects with normal occlusion were examined. In these subjects, the tooth-size data sets in the maxilla and the mandible were clustered for men and women by using multivariate normal mixture models. This analy...
متن کاملIntermaxillary tooth size discrepancies among different malocclusion groups.
The aims of this study were to identify possible gender-related differences in tooth size ratios, to determine whether there is a prevalence for intermaxillary tooth size discrepancies in any malocclusion group, and to detect the percentage of tooth size discrepancies outside 1 or 2 standard deviations (SDs) from Bolton's mean. The material comprised the models of 500 subjects (284 females and ...
