摘要:
目的 通过树脂模拟根管比较HyFlex、S3、K3XF以及ProTaper的成形能力。方法 40个单弯树脂模拟根管随机分为4组,分别使用HyFlex、S3、K3XF以及ProTaper预备根管,数码相机采集预备前后根管的形态,采用图片处理软件Photoshop CS5将其重叠,通过分析软件AutoCAD 2010计算10个观测点的根管树脂去除量并计算中心定位能力,采用SPSS 17.0对数据进行单因素方差分析。结果 HyFlex无器械分离,其他3种器械各发生1例。在距根尖2、3 mm处HyFlex的中心定位能力最好(P<0.05),在4~6 mm处则是K3XF最好(P<0.05)。结论 4种器械预备后的树脂根管都保持着较好的根管形态,没有明显的偏移、台阶出现。HyFlex在根尖段的成形能力最好,K3XF则在根管中段更有优势。
