摘要

目的:比较不同热处理镍钛旋转系统在管内温度下的抗循环疲劳性能。方法:共90个OneCurve (Micro-Mega, besanon, France), VDW。旋转(VDW Dental,慕尼黑,德国),Typhoon (Clinician’s Choice, New Milford, CT,美国),HyFlex EDM (Coltene/Whaledent AG, Altstatten,瑞士),EndoArt Gold and Blue (Inci Dental, Istanbul,土耳其)(n = 15)旋转锉(#25/0.06)在内径1.5 mm,曲率角60°,曲率半径2mm的不锈钢人工管中使用动态模型在管内温度(35.5℃)下进行测试。测试一直持续到压裂,此时设备自动停止,旋转次数以秒为单位计算。使用数字卡尺测量断裂部位的长度。组间比较采用单因素方差分析和Tukey检验。通过扫描电镜分析确定了断裂类型。结果:EndoArt Blue组的平均骨折时间明显高于其他各组,其次是HyFlex EDM、VDW。旋转,一曲线,黄金和台风。此外,HyFlex的EDM和VDW。ROTATE组之间无显著差异,且明显优于其他组。OneCurve组、EndoArt Gold组和Typhoon组间差异无统计学意义(p>0.05)。结论:这是文献中首次对EndoArt NiTi锉进行研究,第二次对VDW进行研究。旋转,评估循环疲劳抗力。新型EndoArt Blue锉比其他NiTi锉具有更强的抗循环疲劳性能。本文来源:Güneç HG, Keskin NB, Haznedaroğlu F.不同和新型热处理镍钛旋转锉在管内温度下的循环疲劳性能比较。国际医学杂志,2011;11(3):158-64。https://doi.org/10.5577/intdentres.2021.vol11.no3.4语言修改:本手稿中的英语已由至少两名专业编辑检查,他们都是英语母语者。

Comparison of cyclic fatigue resistance of different and novel heat-treated nickel-titanium rotary file systems at the intracanal temperature
Aim: The aim of this study was to compare the cyclic fatigue resistance of different heat-treated nickel-titanium rotary systems at intracanal temperature.  Methodology: A total of 90 OneCurve (Micro-Mega, Besançon, France), VDW.ROTATE (VDW Dental, Munich, Germany), Typhoon (Clinician’s Choice, New Milford, CT, USA), HyFlex EDM (Coltene/Whaledent AG, Altstatten, Switzerland), and EndoArt Gold and Blue (Inci Dental, Istanbul, Turkey) (n = 15) rotary files (#25/0.06) were tested at intracanal temperature (35.5 ℃) using a dynamic model in a stainless-steel artificial canal with an inner diameter of 1.5 mm, 60° angle of curvature, and 2 mm radius of curvature. Testing was conducted until fracturing, at which time the device stopped automatically, and the number of rotations was calculated as seconds. Lengths of fractured parts were measured using a digital caliper. One-way ANOVA test followed by Tukey’s test was used to compare the groups. Scanning electron microscopic evaluation was performed to confirm the types of fracture. Results: EndoArt Blue group had a significantly higher mean time to fracture in all groups, followed by the HyFlex EDM, VDW.ROTATE, OneCurve, EndoArt Gold, and Typhoon. In addition, the HyFlex EDM and VDW.ROTATE groups had no significant differences between each other and were significantly better than the others. No significant differences were found between the OneCurve, EndoArt Gold, and Typhoon groups (p>0.05). Conclusion: This is the first study in the literature for EndoArt NiTi files and the second study for VDW.ROTATE that evaluated cyclic fatigue resistance. Novel EndoArt Blue files exhibited significantly greater cyclic fatigue resistance than the other NiTi files.   How to cite this article: Güneç HG, Keskin NB, Haznedaroğlu F.
