Prevalence of dental anomalies in cleft lip and palate patients

Abstract

The study was performed to investigate the prevalence of dental anomalies in Moroccan patients with cleft lip and palate. Ninety-six cleft patients referring to the dental care center of Casablanca (CCTD) and the Operation Smile Morocco center were included in this cross-sectional study. Ethical clearance for the study was obtained from Institutional Review Committee. Demographic data were collected and radiographs were evaluated for possible dental anomalies. We managed to compare dental anomaly traits based on gender. Data were analyzed using SPSS version 16.0. The differences in dental anomalies were compared using the Chi-square test. The most frequent cleft type was left unilateral cleft lip and palate (42,7%) and male predominance (55,2%) was observed. The most common anomaly was dental agenesis especially of the maxillary lateral incisor (24.7%). Regarding other types of dental anomalies, the microdontia and the amelogenesis imperfecta were the most frequent anomalies with significant differences between the two sexes (P <0.05). Hypodontia, microdontia and amelogenesis imperfecta were the most prevalent dental anomalies among Moroccan patients with cleft lip and palate. However, the frequency of dental anomalies in cleft patients suggests that careful planning and implementation of specialist services should be performed to provide early and adequate detection and treatment.
