單側唇裂患者之先天性缺牙發生率
A Research Report-Congenitally Missing Teeth in Unilateral Cleft Lip and Alveolus Children
摘要
目的：針對南台灣單側唇裂兒童齒列，以回溯性之研究方式藉此了解其恆齒先天缺牙率。病人：高雄長庚醫院齒顎矯正科自西元1983年7月至2008年6月期間，年齡介於10歲至12歲之間的680位單側唇裂患者。方法：以臨床牙科記錄，搭配牙齒模型、環口X光片、前牙區根尖片、以及上顎咬合片等加以檢視。結果：上顎側門牙在患側（齒槽裂縫）之先天缺牙率是79.12 %，在非患側之先天缺牙率是3.82%；上顎正中門牙在患側（齒槽裂縫）之先天缺牙率是4.85%，在非患側之先天缺牙率是0.29%；上顎第二小臼齒在患側（齒槽裂縫）之先天缺牙率是2.79 %，在非患側之先天缺牙率是2.06 %；患側及非患側同時先天缺少上顎側門牙的比率是3.82%，同時先天缺少上顎正中門齒的比率是0.29%，同時缺少上顎第二小臼齒的比率是0.88 %。結論：單側唇裂患者之先天缺牙發生率由高而低依序分別為：裂縫側的上顎側門牙、裂縫側的上顎正中門牙、非裂縫側的上顎側門牙。

Objective: To retrospectively study the dentition of southern Taiwan children with unilateral complete cleft lip and alveolus for the prevalence of hypodontia.Patients: 680 Taiwan children with unilateral complete cleft lip and alveolus aged between 10 and 12 years from July 1983 to June, 2008 in Department of Orthodontics, Kaohsiung Chang Cung Memorial Hospital.Material and methods: Dental records were studied as were the panoramic radiograph, periapical films of anterior teeth, upper occlusal films and dental model from which the dentition was examined.Results: The prevalence of congenitally missing maxillary lateral incisor was 79.12% of cleft side and 3.82% on non-cleft side. The prevalence of congenitally missing maxillary central incisor was 4.85% of cleft side and 0.29% on non-cleft side. The prevalence of congenitally missing maxillary second premolar was 2.79% of cleft side and 2.06% on the non-cleft side. The prevalence of bilateral congenitally missing maxillary lateral incisor, central incisor and second premolar was 3.82%, 0.29% and 0.88% respectively.Conclusion: This group of Taiwan children with unilateral complete cleft lip and alveolus demonstrated the highest prevalence of congenitally missing maxillary lateral incisor on the cleft side followed by maxillary central incisor on the cleft side and the n maxillary lateral incisor on the non-cleft side.
