Abstract

BACKGROUND

Cleaning and debriding the canals and preserving the shape of the canal without deformation is the primary goals of pulpectomy. Transportation is a critical endodontic iatrogenic fault that could cause a catastrophe. This study evaluated the canal centering ability and canal transportation caused by Kedo-S pediatric and Mtwo instruments, using a cone-beam computed tomography (CBCT).

MATERIALS AND METHODS

This study was performed on distal roots of 50 primary mandibular first molars. The teeth were scanned using CBCT and randomly divided into two groups. The canals were then prepared using either Kedo-S or Mtwo files ( = 25). The instrumented canals were rescanned. The scanned volumes were sectioned at 2, 4, and 6 mm from cementoenamel junction (CEJ). Canal transportation (CT) and instrument centering ability were estimated and compared in both groups.

RESULTS

The mean values for two study groups were compared. -test was used to determine the value. The Levene's test was used to test the significance between two groups. The two groups showed similar results in terms of transportation and centering ability ( > 0.05).

CONCLUSION

Kedo-S pediatric and Mtwo instruments demonstrated similar canal centering ability and CTs.

摘要

背景

清理和清创根管并保持根管形态不变形是牙髓摘除术的主要目标。根管偏移是一种严重的医源性根管治疗失误，可能导致严重后果。本研究使用锥形束计算机断层扫描（CBCT）评估了Kedo-S儿童根管器械和Mtwo器械的根管就位能力及根管偏移情况。

材料与方法

本研究对50颗下颌第一乳磨牙的远中根进行。使用CBCT对牙齿进行扫描，并随机分为两组。然后分别使用Kedo-S或Mtwo锉（每组25颗）预备根管。对预备后的根管再次进行扫描。在距牙骨质釉质界（CEJ）2、4和6mm处对扫描体积进行切片。评估并比较两组的根管偏移（CT）和器械就位能力。

结果

比较了两个研究组的平均值。采用t检验确定数值。采用Levene检验来检验两组之间的显著性。两组在根管偏移和就位能力方面显示出相似的结果（P>0.05）。

结论

Kedo-S儿童根管器械和Mtwo器械显示出相似的根管就位能力和根管偏移情况。
