Description
Summary:Significant heterogeneity has previously been reported but with no consensus on the prevalence of dental anomalies in subjects with a cleft lip and palate (CLP), thus, the purpose of this study was to investigate the frequency of various dental anomalies in the upper dental arch in different cleft groups. Diagnostic records, i.e., panoramic, occlusal and periapical films, dental casts, and intra-oral photographs, of 122 subjects (mean age: 14 ± 5 years; 67 males and 55 females) were grouped as either unilateral left cleft lip and palate (ULCLP), unilateral right cleft lip and palate (URCLP), bilateral cleft lip and palate (BCLP), or cleft palate (CP). Prevalence rates of 15 different dental anomalies were calculated for each group. Wilcoxon's test was used to determine if there was a statistically significant difference in the number of missing teeth between the right and left sides, in each cleft group. Overall, 96.7 per cent of patients were found to have at least one dental anomaly. The most prevalent was agenesis in the anterior region on the cleft side (70.8–97.1 per cent). There was a statistically significant difference in the prevalence of agenesis by cleft and non-cleft sides but only in the ULCLP group (P < 0.001). Significantly higher rates of impaction were observed in the anterior and premolar regions in the CLP groups (2.9–29.2 per cent), with the highest rates in the anterior region on the cleft sides. A very high proportion of subjects were found to have at least one dental anomaly. Thus, the management of dental anomalies should be central to the treatment planning process of individuals with a cleft.
