The purpose of this study was to investigate the characteristics of premaxillary supernumerary teeth among children in Taiwan. The study population consisted of 112 children, ranging in age from four years to fourteen years. The characteristics of supernumerary teeth were obtained from radiographs and clinical examination, and were confirmed by surgical intervention. The results showed that males were affected approximately three times as frequently as female. About 36 percent of the patients had more than one supernumerary tooth and more than 96 percent of supernumerary teeth occurred in the central incisor region. About 46 percent of the supernumerary teeth were in the vertical position, 34 percent of the supernumerary teeth were erupted; and the eruption rate of conical shaped and tuberculate shaped supernumerary teeth were similar.
