A Comparison of some Features of the Indonesian Occlusion with those of two other Ethnic Groups

Abstract

A sample of 184 randomly selected Indonesian children aged from 7 to 13 years from Surabaya, Java was examined for the prevalence of dental malocclusion. The examination was supported by cephalometric and photographic records and dental casts. Results showed a high prevalence of incisor crowding, bimaxillary prognathism, and a class I molar relationship. While crowding was very common, there appeared to be few antero-posterior, vertical or lateral discrepancies.
