摘要
目的:探讨家族遗传性多生牙的潜在病因及治疗手段。方法:对我院收治的1例有家族遗传史的多发性多生牙患者进行诊治,结合影像学对多生牙行术前定位,术中避免损伤邻近组织并彻底清除牙囊,术后随访观察拔牙创愈合及患者主观情况。结果:术后患者创口愈合良好,颌面部外形及咀嚼功能正常,无不适。结论:多生牙是一种牙齿数目多于人体生理牙数的牙齿发育异常,家族遗传性多生牙多见于伴全身综合征的病例,非综合征型临床上少见。通过影像学的辅助可准确诊断多生牙的数目及位置,利于手术进路及牙拔除方向的确定。
Objective: To discuss the potential pathogeny and corresponding therapy of supernumerary teeth accompanying with family heredity.Methods: A patient suffering from supernumerary teeth accompanying with family history was treated in Sun Yat-Sen Memorial Hospital.Iconography was used in the predetermined design of supernumerary teeth.A operation was performed to avoid injuring the proximal tissue and completely clean the dental crypt.Postoperatively,the patient was regularly checked and observed the concrescence of the tooth extraction wound and the patient's healthy conditions.Result: According to the postoperative follow-up,the wound's concrescence was in good circumstances.The patient's outer appearance of maxillofacial region and mastication function returned to normal conditions.Conclusion: Supernumerary teeth belongs to a kind of abnormity of tooth growth,which the patient's tooth number is more than normal one.Family heredity often appears in the cases of syndrome all over the body but little non-syndrome ones.Through the assistance of iconography,the number and location of supernumerary teeth can be determined accurately,which is important to the design of operative approach and direction of tooth extraction.
