Dental problems cause not only esthetic but dental problems such as functional disorder, dental caries, pulp disease and malocclusions, and in particular, masticatory problem falls on infants or children, which has effect on articulation disorder and emotional development as well as their physical growth. Therefore, it's important to detect dental problems early and to provide comparable indications. The purose of this study was to find out the prevalence and pattern of dental developmental anomalies. The clinical and radiographic examination was undertaken for 1,032 at age from 1 to 10 years and statistical analysis was done. The result were as follows. Among the examined patients, 333 patients( 32.3%) showed dental developmental anomalies. The prevalences of individual dental anomalies were as follows ; congenital missing teeth 11.6%, supernumerary teeth 6.2%, taurodontism teeth 3.9%, fusion teeth 3.8%, microdontia teeth 3.2%, dens evaginatus teeth 2.3%, dens invaginatus teeth 0.6%, talon cusp teeth 0.2%, macrodontia teeth 0.1%, Dilaceration teeth 0.1%, transposition teeth 0.1%, inverted teeth 0.1%, amelogenesis imperfecta 0.1%.. The anomalies of number(53.6%), the anomalies of shape(37.7%,) the anomalies of size(8.3%), the anomalies of position(0.3%) and the anomalies of structure(0.2%.) were examined. Most supernumerary teeth located on middle. area showed inverted position and unerupted state. The most frequently missing teeth was the mandibular primary lateral incisor(65.6%) and the mandibular 2nd. premolar. In the case of deciduous congenital missing teeth, the prevalence of successive permanent congenital missing teeth (65.6%) was highest in mandibular lateral incisors.. The higher prevalence of microdontia teeth was maxilla lateral incisor, dens evaginatus teeth was mandibular 2nd. premolar, dens invaginatus teeth was maxilla lateral incisor, and taurodontism was mandibular 1st. molar. Teeth play an important role for mastication, articulation, and aesthetic of adults as well as of children. The health of oral cavity could be kept by controling dental problems of children in the basis of the epidermiologic research of oral pathologic field.
