The purpose of this study was % find out the prevalence of dental anomalies in 600
normal persons(male:363, female:237) at age 14 to 39 years, through history taking, oral
examination, and radiographic observations of subjects.
The obtained results were as follows :
1. The prevalences of individual dental anomalies were as follows; Congenitally
missing teeth 7%; supernumerary teeth 1.33%; ectopic eruption; 8.50%,
transposition;0.33% rotation; 23.67%, microdontia ;11.16%(peg lateralis; 5.33%, third
molar;5.83%), prolonged retention of deciduous teeth;1.33%, crowding 49.83%, and
spacing:15.17%.
2. Alterations in numbers of teeth : The most frequently missing teeth were
mandibular lateral incisors, followed by mandibular second premolars and maxillary
second Premolars. In numbers of congenitally missing teeth per person, 52.38% had one
missing tooth and 30.95% had two missing teeth. In supernumerary teeth, there was
higher rate in male than in female. Most supernumerary teeth were mesiodens of
median area in maxilla and the eruption pattern of that teeth generally was unerupted
state.
3. In transposition, exchange of position of teeth involved the canine and first
premolar.
4. Congenital missing rate of permanent successors in prolonged retention of deciduous
teeth was 69.23%.
5. Crowing and spacing had respectively higher rate in mandible and in maxilla.
