MSCT在埋伏牙定位诊断中的应用
|
摘要
目的探讨多层螺旋CT(MSCT在埋伏牙定位诊断中的应用价值。方法回顾性分析2016年5月-2018年5月我院口腔科收治的76例埋伏牙患者的临床资料。所有患者经常规口腔全景断层摄影检查确诊和手术证实,因定位模糊行MSCT检查和三维重建处理,根据图像分析埋伏牙数量、位置、形态、牙根吸收情况以及与周围组织关系。结果 76例患者检出埋伏牙84颗,单颗埋伏牙患者占总数最高(90.79%);牙位分布以上颌尖牙(33.33%)、中切牙(22.62%)、侧切牙(17.86%)占比较高;唇腭侧分布以舌腭侧埋伏为主,占比72.62%;邻牙牙根无吸收占45.24%,轻度吸收占33.93%;MSCT对埋伏牙的定位诊断准确率为100%。结论MSCT检查和三维重建对埋伏牙有十分精准的定位和诊断,可清晰显示埋伏牙数目、唇腭侧分布、牙根吸收等情况,可作为临床矫治的重要影像学参考资料。
Objective To explore the application value of multi-slice spiral CT(MSCT)in the localization diagnosis of embedded teeth. Methods The clinical data of 76 patients with embedded teeth who were treated in department of stomatology of our hospital from May 2016 to May 2018 were analyzed retrospectively. All patients were confirmed by conventional oral panoramic tomography examination and verified by surgery, and they were given MSCT and three-dimensional reconstruction due to ambiguous localization.The quantity, sites and shape of embedded teeth and root resorption and their relationship with the surrounding tissues were analyzed according to the images. Results A total of 84 embedded teeth were found among 76 patients. The number of single embedded teeth was the highest proportion(90.79%) in the total sum. The distribution of teeth sites was of higher proportion in maxillary canine(33.33%), central incisor(22.62%) and lateral incisor(17.86%). Labiopalatine lateral distribution was mainly embedded lingual side, accounting for 72.62%. The non-absorption of adjacent teeth accounted for 45.24%, and the light absorption accounted for 33.93%. The accuracy of MSCT was 100 % in the diagnosis of embedded teeth. Conclusion MSCT and three-dimensional reconstruction have accurate localization and diagnosis of embedded teeth, and it can clearly show the embedded teeth quantity, labiopalatine lateral distribution and root resorption. And it can be used as an important imaging reference for clinical correction.
