Abstract:
OBJECTIVE: The purpose of this study was to investigate the prevalence of dental anomalies in outpatient clinics. METHODS: The subjects of this study were 3,133 patients who visited the clinic between January 2009 and June 2011. The dental records and panoramic films of the patients and detection of supernumerary, missing, and impacted teeth, transposition, and peg lateralis were reviewed. The results were analyzed according to gender and types and locations of dental anomalies. RESULTS: Among the patients, 362 had dental anomalies, with a prevalence rate of 11.55%. Congenital missing teeth (5.71%) ranked first in the categories, and impacted teeth (3.09%) ranked second. The percentage of patients having supernumerary teeth, peg lateralis, and dislocated teeth were 1.79%, 1.66%, and 0.45%, respectively. CONCLUSIONS: Congenital missing teeth and impacted teeth are, respectively, the first and second most common dental anomalies in Korean dental patients.
