埋伏多生牙囊变的临床与病理研究

The Clinical and Pathologic Study of Embeded Supernumerary Teeth

目的 通过 10 0例埋伏多生牙的临床与病理分析 ,寻找埋伏多生牙囊变的规律及与错牙合畸形的关系 ,提出相应的治疗方法。方法 通过临床资料的分析、X线检查、术中所见及病理细胞学变化的对照 ,为诊断埋伏多生牙囊变提供依据。结果 10 0例埋伏多生牙中 ,经X线检查发现 6 6 %的病例多生牙冠部有不同程度的圆形透光阴影 ,而病理证实有囊变的仅为 35 %。结论 本组埋伏多生牙有囊变的占相当大比例。因此对确定为埋伏多生牙的患者 ,如有手术适应证 。

Objective To analyse the clinic and pathologic features of 100 embeded supernumerary teeth, to find out the rule of cystic change of supernumerary teeth and its relationship to malocclusion, and to present the methods of therapy. Methods Analysis of clinical data ,X ray manifestation, comparison of the findings on operation and pathological changes demonstrated the correct diagnosis of supernumerary teeth. Results On statistics and analysis,66% of the crowns of the supernumerary teeth were showed different sizes of circular photic shades,but only 35% were proved to be cystic change by biopsies. Conclusion This study showed that 35% had cystic change among 100 cases,so if the diagnosis can be made in these cases with indication of operation, the extraction of the supernumerary teeth must be done as soon as possible.
