Cleft genes produce disturbances in many body tissues and therefore also affect the dental lamina leading to Dental anomalies, a complication for the treatment planning of cleft patients which has been proposed to occur more frequently than in healthy patients..A high incidence of dental anomalies in the anterior maxillary region has been noted by various investigators, mainly at the level of lateral incisor both in deciduous and the permanent dentition. The purpose of this study was to evaluate the incidence of incisal abnormalities in cleft lip and palate patients. This study was carried out on 113 untreated unilateral cleft lip and palate patients of which 62 were males and 51 females. The included samples consisted of 113 dental casts of unilateral cleft lip and palate subjects ranging in age from 7 to 12 years. The examination of the diagnostic casts showed incisal abnormalities in the maxillary arch like Missing lateral incisors (12 & 22),Rotated lateral incisors (12 & 22),Rotated central incisors (11 & 21) and Combination of the above.The result of this study revealed higher percentage of absence of left lateral incisors (48.7%) ,rotated right lateral inciosrs(22.1%), missing right lateral incisors (21.2%) and rotated right central incisors (18.6%).Hence The study group consisting children with unilateral cleft lip and palate showed predominance of clefts on left side with laterals incisors being the tooth most affected.
