영문 초록

The aim of this study was to investigate the prevalence of congenital missing, supernumerary teeth, and size, shape and rotation of the maxillary anterior teeth in patients with cleft lip and alveolus. Thirty- four individuals (male 13, female 21) with cleft lip and alveolus was selected. After look up the medical history, panorama X-ray and intraoral photos were investigated. The congenital missing teeth ratio was 26.5% (9/34) and all the missing tooth was maxillary lateral incisor. The ratio of supernumerary tooth was 17.6% (6/34) and 2 supernumerary tooth was mesial to the cleft and 4 was distal to the cleft. The ratio of small tooth was 67.6% (23/34) and 8 (34.8%) was located mesial to the cleft, 15 (65.2%) was distal to the cleft. Rotated tooth was 64.7% (22/34) and all the tooth was maxillary central incisor of cleft side. The result suggested that maxillary process influenced more than median nasal process in formation of lateral incisor. This result suggested that it is necessary to study the embryologic relationship between cleft lip and alveolus and dental abnormalities.
