Objective: To investigate the prevalence of anterior maxillary dental anomalies in patients with complete unilateral cleft lip and palate. Methods: The cone beam computed tomography( CBCT) images and medical charts of 112 patients with complete unilateral cleft lip and palate were examined. The prevalence of five categories of dental anomalies was assessed and compared between cleft side and non-cleft side. The position of upper anterior teeth on the cleft and non-cleft side was also compared. Results: Overall,97. 3% of the patients were found to have at least one dental anomaly. The lateral incisor was the most often absent tooth( 80. 0%). The congenital absence of tooth,tooth deformity,and the rotation of the central incisor had a higher prevalence on the cleft side,showing a statistically significant difference. The most common position of anterior teeth on the cleft side is that the lateral incisor was located at the palatal side of canine( 35. 6%). Conclusion:The various dental anomalies of patients with complete unilateral cleft lip and palate can be effectively assessed by CBCT. The lateral incisor could been important while making the treatment plan.
