Hypodontia in the permanent dentition: a study of its prevalence in Malaysian children.
An investigation of the prevalence and distribution of hypodontia was carried out in Malaysian children between the ages of five to fifteen years. Hypodontia occurred in 2.8 per cent of these children. A greater number of females were found to have hypodontia, the ratio of affected females to males is 1.6:1. The teeth most frequently missing were the maxillary lateral incisors followed by the mandibular lateral incisors, then the mandibular second premolars. The aetiology of the condition is discussed. It is noteworthy that studies showing the lower second premolars to be most commonly missing have younger subjects. This suggests delayed development of these teeth in some individuals.
