Eighty nine [59.3%] patients had dental anomalies of various types. Forty-two patients [28%] were found with missing teeth. Third molar was most common missing tooth. Third molar impaction carried the highest percentage [10.3%] followed by maxillary canine [4.1%]. Six cases had supernumerary teeth [4.1%] while three have odontomes [2%]
