Abstract

Data derived from odontometric studies are useful in many areas. Especially crown diameter of primary teeth is important in not only anthropology but also clinical dentistry. The purposes of this study were to compare diameters of primary molars of Korean children with those of preformed stainless steel crown, and examine racial characteristics of primary molars of Korean children. The mesiodistal and buccolingual diameters of primary molars were measured on dental casts taken from 235 children(male 105, female 131), with digital calipers. And the data were compared with those of preformed stainless steel crowns. The results were as follows; 1. No significant difference was observed between the right and left members of antimeric teeth and all primary molars of male were larger than those of female. 2. The diameters of primary molars of Korean are smaller than those of Austrailian aborigines and there was significant difference between diameters of primary molars of Korean and those of other populations. 3. There were size differences between diameters of maxillary, mandibular first molar and preformed stainless steel crown than other primary molars, relatively.
