To compare and evaluate canal preparation using hand stainless steel files, hand ProTaper files, and rotary ProTaper files for change in root canal geometry in terms of surface area and volume changes assessed by computed tomography.
The present study was conducted in Nair Hospital and Dental College, Department of Pediatric and Preventive Dentistry in collaboration with insight CBCT, imaging technologies. A total of 36 extracted human primary mandibular second molars were collected from the Department of Pediatric and Preventive Dentistry. All the teeth were scanned using cone-beam CT (i-CAT CT Scanner Next Generation, Imaging Sciences International) preoperatively and postoperatively to assess the mean absolute change in surface area and mean change in the volume of all the canals at different levels with the use of hand stainless steel files, hand ProTaper and rotary ProTaper files.
ProTaper instruments, both hand ProTaper and rotary ProTaper caused significant changes in the surface area in the coronal thirds and middle thirds of the canal when compared to hand stainless steel files. No difference was found in surface area and volume changes between hand ProTaper and rotary ProTaper instrumentation.
Use of ProTaper instruments for preparation of deciduous teeth can render benefit of an improved canal preparation to facilitate better obturation and successful root canal therapy.

使用计算机断层扫描评估表面积和体积变化,比较和评价使用手动不锈钢锉、手动ProTaper锉和旋转ProTaper锉进行根管预备时根管形态的变化。
本研究在奈尔医院和牙科学院的儿童与预防牙科系与insight CBCT影像技术公司合作开展。从儿童与预防牙科系收集了36颗拔除的人类下颌乳第二磨牙。所有牙齿在术前和术后均使用锥形束CT(i-CAT CT Scanner Next Generation,Imaging Sciences International)进行扫描,以评估使用手动不锈钢锉、手动ProTaper锉和旋转ProTaper锉时不同水平所有根管的表面积平均绝对变化和体积平均变化。
与手动不锈钢锉相比,ProTaper器械,包括手动ProTaper锉和旋转ProTaper锉,在根管的冠三分之一和中三分之一处引起了显著的表面积变化。手动ProTaper锉和旋转ProTaper锉器械在表面积和体积变化方面未发现差异。
使用ProTaper器械预备乳牙可改善根管预备,有利于更好地进行根管充填和成功的根管治疗。
