This study was undertaken in order to observe the prevalence of congenital dental
anomalies especially that of oligodontia and supernumerary teeth in 1024 children at age
from 4 to 14 years, through history taking, oral examinations, roentgenographic
observations of subjects, and statistic analysis was made.
The following results were obtained :
1. The prevalence of oligodontia in 1024 children was 6.45¡¾.8 percent with a total of
122 teeth absent in sixty-six subjects, excluding 3rd molars, and most of children
(86.4%) who have congenitally missing teeth showed abscence of one or two teeth
individually.
2. The teeth most frequently absent were the mandibular second premolar, maxillary
second premolar, maxillary lateral incisor, mandibular central incisor, and mandibular
lateral incisor in order.
3. There was no statistically significant difference found in tooth abscence in the
following comparisons;
.Male vs Female
.Bilateral vs Unilateral
.Maxilla vs Mandible
.Right vs Left
4. The prevalence of supernumerary teeth in 1024 children was 4.79¡¾.67 percent with a
total of 59 supernumerary teeth in forty-nine subjects, all of children who have
supernumerary teeth showed one or two supernumerary teeth individually.
5. Statistically significant difference was found in supernumerary teeth in the
comparison of male vs female, and they were more frequent in male.
