Abstract

Objective: We evaluated the effect of brushing motion on microcrack formation in round distal canals after using multi-file rotary(MFR), single-file rotary(SFR), and single-file reciprocation(SFRc) systems via micro-computed tomography(micro-CT).

Materials and methods: Thirty-six mandibular molars were used. Samples were allocated according to files and preparation patterns (n = 12); pecking (P) and brushing (B): Group-MFR-P, Group-MFR-B, Group-SFRc-P, Group-SFRc-B, Group-SFR-P, Group-SFR-B. MFR was ProTaper Next, SFR was TruNatomy, and SFRc was WaveOne Gold. Mesial and distal were prepared using pecking motion, and additional brushing motion. Brushing motions were performed after the pecking motions with 6 strokes. Pre-and-post-instrumentation scans were obtained. Wilcoxon, Krukal-Wallis, and Mann-Whitney-U were performed.

Results: No differences were between pre-and-post-instrumentation scans (p > 0.05). Post-instrumentation microcracks were not different in Group MFR-P and Group MFR-B, Group SFRc-P and Group SFRc-B, Group SFR-P and Group SFR-B (p > 0.05).

Conclusion: The brushing motion followed by the pecking motion did not cause microcracks. None of the file systems examined in the study induced microcracks.

一项微型计算机断层扫描研究表明，刷牙运动不会引起微裂纹。

目的：通过显微计算机断层扫描（micro-CT）评估刷牙运动对使用多锉旋转（MFR）、单锉旋转（SFR）和单锉往复（SFRc）系统后圆形远端根管微裂纹形成的影响。材料与方法：使用下颌磨牙36颗。按文件和制备模式分配样本（n = 12）；啄(P)和刷(B): Group-MFR-P、Group-MFR-B、Group-SFR-P、Group-SFR-B、Group-SFR-P、Group-SFR-B。MFR为ProTaper Next， SFR为TruNatomy， SFRc为WaveOne Gold。近端和远端预备采用啄动和额外的刷动。在6次啄击动作后进行刷毛动作。获得了仪器前和仪器后的扫描。行Wilcoxon、Krukal-Wallis、Mann-Whitney-U检查。结果：置入前后扫描无差异（p < 0.05）。MFR-P组与MFR-B组、SFR-P组与SFR-B组、SFR-P组与SFR-B组置入后微裂纹无显著性差异（p < 0.05）。结论：先刷牙后啄牙不会引起微裂纹。在研究中检查的文件系统都没有引起微裂纹。

期刊介绍： The journal Clinical Oral Investigations is a multidisciplinary, international forum for publication of research from all fields of oral medicine. The journal publishes original scientific articles and invited reviews which provide up-to-date results of basic and clinical studies in oral and maxillofacial science and medicine. The aim is to clarify the relevance of new results to modern practice, for an international readership. Coverage includes maxillofacial and oral surgery, prosthetics and restorative dentistry, operative dentistry, endodontics, periodontology, orthodontics, dental materials science, clinical trials, epidemiology, pedodontics, oral implant, preventive dentistiry, oral pathology, oral basic sciences and more.
