Description
Cleft lip, alveolus and/or palate (CLP) is the most frequent congenital craniofacial malformation. It is known that this malformation occurs in a ratio of about one to 500 birth in Japanese. Most of them have absence of teeth, supernumerary teeth, fused teeth, abnormalities of tooth eruption and/or enamel dysplasia. Because of these abnormalities, caries risk in CLP children is higher than that in the normal ones.<BR>The first purpose of this study is to survey the correlation between the types of cleft and malformation of tooth. Especially, we focus on the enamel dysplasia. The second purpose is to survey caries risk of CLP children. We examined the primary dentition of the CLP children who visited the clinic of pediatric dentistry in Kyushu University Hospital.<BR>The following results were obtained.<BR>1. Cleft alveolus children tend to have abnormalities of tooth on the cleft side of maxilla, but some have abnormalities of tooth on the opposite side of maxilla which has no cleft, as well as mandible.<BR>2. Cleft palate children without cleft alveorus do not have abnormalities of tooth in the right side of maxilla.<BR>3. Caries risk of cleft palate children is lower than that of normal ones.<BR>These results indicate that we have to perform three important steps for CLP children as follows. Firstly, to predict the abnormalities of primary teeth of CLP children. Secondly, to give oral hygiene instruction for the parents of CLP children. Thirdly, to perform a periodical examination to prevent new dental caries for CLP children.
