Abstract

This study compared the preparation of long oval-shaped root canals using WaveOne Gold and XP-endo Shaper systems, both supplemented or not with manual instrumentation. Twenty-four long oval-shaped canals of mandibular incisors were distributed into two groups according to the instrumentation: WaveOne Gold Primary or XP-endo Shaper systems. All root canals were manually instrumented with a size 25 K-file after automated preparation. The specimens were scanned by using a micro-CT device (17.42 µm) before and after automated preparation and manual instrumentation. The increased surface of the root canal and the percentage of untouched areas were assessed. Both WaveOne Gold and XP-endo Shaper systems increased the root canal surface and had similar untouched areas (p>0.05). Supplementary instrumentation increased the surface of the root canal and decreased the untouched walls (p<0.05). WaveOne Gold and XP-endo Shaper systems provided a similar preparation of long oval-shaped canals and manual instrumentation improved their preparation.

辅助器械自动制备长椭圆形根管的优化研究。

本研究比较了使用WaveOne Gold和XP-endo Shaper系统制备长椭圆形根管的情况，两者都辅以或不辅以人工器械。24根长椭圆形的下切牙根管根据器械的不同分为WaveOne Gold Primary和XP-endo Shaper两组。所有的根管在自动准备后都手工用25k大小的锉进行根管预备。在自动制备和人工检测前后，采用微ct(17.42µm)扫描。评估了增加的根管表面和未触及区域的百分比。WaveOne Gold和XP-endo Shaper系统均增加了根管表面，且未触及面积相似(p>0.05)。辅助器械增加了根管表面，减少了未触及的管壁(p
