摘要
简介:本研究旨在比较两种单锉整形系统在消毒和清洁长椭圆形根管方面的能力。材料与方法:制备粪肠球菌污染的单根牙50颗，分为两组。获得两次采样;化学机械制备前为S1，制备后为S2。根据组的不同，使用XP-endo Shaper (XPS)和Wave One Gold (WOG)进行化学机械制备。每组5颗牙在1000倍扫描电镜下观察距离根尖3、6、9 mm的根管清洁度。所有概率(p值)均为双尾，统计学显著性设为0.05，采用SPSS统计软件进行分析。结果:在两个测试组中，观察到从S1到S2的集落形成单位显著减少。在S2时，XPS组的菌落形成单位明显低于对照组(p)。结论:在体外实验的基础上，XPS系统对长卵形管的消毒和清洁更有效。
Comparison of Two Reciprocating and Anatomical Single File Techniques in Cleaning Oval Anatomies.
Introduction: The present study aimed to compare the capability of two single-file shaping systems in disinfecting and cleaning long oval root canals.
Materials and methods: Fifty single-rooted teeth were prepared, contaminated with Enterococcus faecalis and divided into two groups. Two samplings were obtained; S1 before chemo-mechanical preparation and S2 after the preparation. Depending on the group, chemo-mechanical preparation was performed with XP-endo Shaper (XPS) and Wave One Gold (WOG). Five teeth from each group were observed under scanning electron microscopy (1000×) to evaluate the cleanliness of root canals at 3, 6 and 9 mm from the apex. All probability (P-values) were two-tailed, statistical significance was set at 0.05 and analyses were conducted using SPSS statistical software.
Results: A significant reduction in the colony forming units was observed from S1 to S2 in both tested groups. In S2, XPS group obtained significantly lower colony forming units (P<0.001). In the cleanliness study, XPS group resulted in significantly cleaner canals compared to WOG.
Conclusions: Based on this in vitro study XPS system was more effective in disinfecting and cleaning long oval canals.
期刊介绍：
The Iranian Endodontic Journal (IEJ) is an international peer-reviewed biomedical publication, the aim of which is to provide a scientific medium of communication for researchers throughout the globe. IEJ aims to publish the highest quality articles, both clinical and scientific, on all aspects of Endodontics. The journal is an official Journal of the Iranian Center for Endodontic Research (ICER) and the Iranian Association of Endodontists (IAE). The Journal welcomes articles related to the scientific or applied aspects of endodontics e.g. original researches, systematic reviews, meta-analyses, review articles, clinical trials, case series/reports, hypotheses, letters to the editor, etc. From the beginning (i.e. since 2006), the IEJ was the first open access endodontic journal in the world, which gave readers free and instant access to published articles and enabling them faster discovery of the latest endodontic research.
