A Correlation Study of Selected Teeth by Circumferential Measurement

A correlation was established among the circumferences of teeth in a given set. This is the first step in constructing a band numbering system so that the fitting of one band (the predictor tooth) would give you the band sizes for the remaining teeth in the set. This would make possible improved efficiency for the orthodontist during band selection. Individual sets of teeth from impressions of patients starting orthodontic treatment were measured by the use of the dentometer. The upper second bicuspid was chosen as the predictor tooth after the correlation matrices were computed. It was concluded that 48% of the sample for males and 42.5% of the sample for females could be predicted to within one band size
