Comparison of tooth size discrepancy of three main ethnics in Malaysia with Bolton ratio (Perbandingan diskrepansi saiz gigi di antara tiga etnik majoriti di Malaysia dengan Nisbah Bolton)

The objective of this study was to investigate the applicability of Bolton’s ratios in orthodontic population of Malaysian main ethnics; Malay, Chinese and Indians. Ninety convenient samples consisting of 30 pre-orthodontic study casts from each ethnic that fits the inclusion criteria were selected....
