摘要
目的评价口腔内窥镜联合超声技术寻找隐匿性根管的效果。方法选取根管治疗时开髓后裸眼下未能顺利找到根管的疑难病例87例,应用口腔内窥镜联合超声技术重新寻找根管口并疏通根管,计算成功率。结果疑难病例87例共发现121个隐匿性根管,其中钙化根管64个,细小根管弯曲根管39个,变异根管18个,成功疏通94个,总成功率为77.68%。对钙化、细小弯曲、变异根管各类型隐匿性根管应用口腔内窥镜联合超声技术寻找及疏通成功率的差异无统计学意义(χ~2=5.477,P>0.05)。结论口腔内窥镜联合超声技术有助于寻找隐匿性根管。
Objective To investigate the efficiency of combined application of dental endoscope and ultrasonictechnique in treating concealed root canals. Methods 87 complicated and difficult cases which were not found root ca-nals during endodontic treatment by naked eyes were selected. The canal orifices were probed and negotiated with theaid of dental endoscope and ultrasonic instruments. And the success rate was recorded. Results 121 concealed root ca-nals which from 87 complicated and difficult cases were classified into 64 calcified canals, 39 narrow curved canals and18 canals with anatomic variation. Among them, 94 canals were found and then negotiated, and the total success ratewas 77.68%. There was no significant difference between the success rates in treating calcified root canals, narrowcurved canals and canals with anatomic variation（c2=5.477, P 0.05）. Conclusion The combined application ofdental endoscope and ultrasonic instruments can effectively improve the success rate of finding and negotiating con-cealed canals.
