显微超声技术在老年人上颌第一磨牙根管治疗中的应用
Combined Application of Microscopy and Ultrasound in the Treatment of the Maxillary First Molar Root Canal of Elderly
摘要
Abstract
Objective:To verify thorough preparation of the mesiobuccal root canal wall of the maxillary first molar of elderly by conventional preparation with Dental microscopy,and to complete the task by ultrasonic instruments. Method:100 elderly cases of maxillary first molar requiring root canal preparation due to endodontitis,periapical inflammation or dental defects were selected in the study. After preparation of root canal with K file,the root canal was examined by microscopy for unprepared root canal wall and residual pulp,which was treated by ultrasonic tips. Then the root canal was rinsed with ultrasound to finish the preparation. Result:After routine preparation of root canal, incompletely prepared root canal wall were observed in 36 of the 100 flat root canals by microscopy,and residual pulp in 20 root canals. Conclusion:Combined use of microscopy and ultrasound can effectively prepare narrow root canal and achieve satisfactory efficacy.关键词
