A Study of Dental Anomalies in Patients with Cleft Lip and/or Palate in Few Dental Clinics of Shiraz in 1383

Statement of Problem: The most prevalent congenital disorder related to palate and lip is clefting. In these patients, the prevalence of dental and skeletal anomalies is more than normal individuals affecting both permanent and milk teeth and is different in different populations due to racial differences. This study was performed to determine the prevalence of dental abnormalities in patients with cleft lip and/or palate. In this cross sectional study, dental casts, lateral cephalograms, panoramic (O.P.G) and periapical (P.A) radiographs and photographs of 51 patients with cleft lip and/or palate were obtained to determine the prevalence of dental anomalies. The collected data were analyzed by SPSS software and the normal and cleft side were compared using Binominal and t-tests. The cleft occurrence was more frequent in males (56.9%) than females (45.1%) while unilateral cleft was more on the left side (47.1%) than the right side (33.4%). The most dental anomaly was tooth missing (70.6%). The upper lateral incisor in the cleft side was more susceptible to dental missing abnormalities. The incidence of dental abnormalities was greater in the cleft side than the noncleft side. Comparing the results of this study to other similar studies, it seems that cleft lip and/or palate patients show similar pattern on the prevalence of the various dental anomalies excluding racial differences.
