Materials and Methods: A retrospective study was conducted to evaluate the panoramic radiographs. Dental anomalies and other abnormalities were recorded.

Patients were between 13 and 30 years of age (mean 19.2 ± 3.39 years), 39.5 % of patients had at least one dental anomaly. Dilaceration was the most common (29.16 %), followed by missing tooth (13.17 %), microdontia (7.21 %), taurodontism (3.29 %), supernumerary tooth (2.66 %), transposition (1.56 %), and the other anomalies (0.155 % – 0.47 %). Conclusion: At least one dental anomaly was found in a sample of Thai orthodontic patients. Dilaceration was the most common anomaly. The prevalence and distribution of dental anomalies are different between the parts of Thai orthodontic patients and between the races.
