【摘要】：目的:比較機(jī)用ProTaperNext和WaveOne在彎曲樹脂模擬根管中的成形能力。方法:選取統(tǒng)一規(guī)格的透明樹脂模擬根管40個(gè),將其隨機(jī)分為2組,分別使用ProTaperNext和WaveOne銼以冠向下技術(shù)預(yù)備兩組樹脂模擬根管。使用ImagePro Plus軟件測(cè)量根管彎曲半徑和彎曲度的變化以及各測(cè)量點(diǎn)去除樹脂量,計(jì)算樹脂去除總量和兩組器械的中心定位力,同時(shí)記錄和分析根管工作長(zhǎng)度的變化和器械變形、分離等參數(shù)。結(jié)果:兩種器械預(yù)備根管時(shí),均能保持較好的工作長(zhǎng)度,不易發(fā)生器械分離,能夠較好的維持根管原始走形,但在根尖段,WaveOne預(yù)備后的根管較易發(fā)生偏移。結(jié)論:ProTaperNext與WaveOne相比,在預(yù)備重度彎曲根管時(shí)具有良好的根管成形能力。
[Abstract]:Objective: To compare the forming ability of ProTaperNext and WaveOne in bending resin to simulate the root canal. Methods: a unified specification of transparent resin was used to simulate 40 root canals. They were randomly divided into 2 groups. ProTaperNext and WaveOne files were used to prepare two groups of resin simulated root canals, respectively. ImagePro Plus software was used to measure the change of root radius and curvature, and the amount of resin removed at each measurement point. The total amount of resin removal and the central positioning force of two groups of instruments were calculated. Meanwhile, the parameters of root canal working length and the deformation and separation of instruments were recorded and analyzed. Results: two kinds of instruments in root canal preparation, can maintain good working length, easy occurrence of instrument separation, can maintain the original canal shape is good, but in the apical segment, WaveOne after root canal preparation is easy to shift. Conclusion: compared with WaveOne, ProTaperNext has good root canal forming ability in the preparation of severe curved root canal.

【正文快照】： 根管預(yù)備是根管治療的關(guān)鍵步驟,根管治療的成功與否很大程度上取決于根管預(yù)備的質(zhì)量。根管預(yù)備主要包括根管清理和根管成形。根管清理是通過(guò)機(jī)械和化學(xué)方法清除根管系統(tǒng)內(nèi)感染的牙髓組織、致病微生物及其代謝產(chǎn)物。根管成形是將根管預(yù)備成一定的形態(tài),以利于根管沖洗和充填。理
