Objectives : The objectives of this study were to investigate the pattern of dental anomalies in orthodontic patients at the Aga Khan University Hospital and to find out the most frequently occurring dental anomaly. Methadology: This was a descriptive study conducted at the dental clinic, the Aga Khan University Hospital, Karachi. The data was collected using pretreatment panoramic radiographs of orthodontic patients who presented at the dental clinic and a total of 570 patients who fulfilled our selection criteria were included in this study. On the pretreatment panoramic radiographs, following dental anomalies were noted: agenesis, supernumerary teeth, dilacerations and taurodontism. Result: Out of a total of 570 patients, dental anomalies were seen in 74 (12.9%) patients. Hypodontia was the most common finding, occurring in 39 (6.8%) patients with the lower second premolar being the most commonly missing tooth (28.2% of all missing teeth). Dilaceration was observed in 25 (4.3%), supernumerary teeth in 6 (1%) and taurodontism in 4 (0.7%) patients. Conclusions: It was observed that about 13% of patients showed at least one dental anomaly. Hypodontia was the most common anomaly while taurodontism was the least frequently seen anomaly.
