[Comparison of different types of cleft lip and palate in regards to dental anomalies and sexual incidence].

Abstract

The present study addresses two questions. Does the incidence of dental anomalies differ among the four following types of cleft lip and palate: the isolated cleft palate, the unilateral cleft lip and palate, (right or left), and the bilateral cleft lip and palate. Furthermore is the sexual incidence comparable among the four above mentioned types? Radiographic records and complete family history of clefting of 156 patients with a complete cleft lip and palate were obtained from the Cleft Lip and Palate Teams of Ste-Justine Hospital. Patients in which the cleft was part of a syndrome were excluded from the study. According to the analysis of the data, the incidence of dental anomalies was relatively high, specifically as high as 92% for the bilateral cleft lip and palate. The sexual incidence differed among the four types.
