RESULTS : Totally170 patients(25.11%) had 165 dental anomalies. Among them Missing of wisdom teeth was the most prevalent anomaly (6.35%) followed by impaction of teeth (2.95%) ,missing of mandibular second premolars (2.36 %) missing of maxillary lateral incisors (2.06%) and taurodontism (1.03%). Family history of dental anomalies was positive in 35.8% of the cases.
