Abstract

Background/purpose

The success of root canal treatments is influenced by the shape of the access opening and the outcomes of root canal enlargement. The aim of this study was to evaluate the impact of various rotary instruments on the maintenance of the root canal's central alignment post shaping, considering a range of access cavity designs.

Materials and methods

Using digital tooth simulation, 4 sets of 12 teeth underwent traditional (TradAC) or conservative (ConsAC) access cavity preparations. Root canals were enlarged with TruNatomy or ProTaper Ultimate rotary instruments. Canal transportation and centering ratio were separately measured. Statistical analysis was performed using JMP trial 17 software.

Results

The analysis revealed no significant difference in buccal and lingual canal transportation among different rotary instruments or canal enlargement designs (P > 0.05). TradAC yielded higher centering ratios in MB and ML canals, while ConsAC excelled in the distal canal for the TruNatomy group. Conversely, in the ProTaper Ultimate group, ConsAC demonstrated higher ML canal ratios (P < 0.05).

Conclusion

TruNatomy maintained superior canal centering with ConsAC, while ProTaper performed better with TradAC.

不同根管开口形状对旋转根管扩大术使用的影响

背景/目的根管治疗的成功与否受通路开口形状和根管扩大结果的影响。本研究的目的是评估各种旋转器械在根管成型后对保持根管中心对齐的影响，同时考虑到一系列的通路洞设计。材料和方法使用数字牙齿模拟，对 4 组 12 颗牙齿进行传统（TradAC）或保守（ConsAC）通路洞预备。使用 TruNatomy 或 ProTaper Ultimate 旋转器械扩大根管。分别测量了根管运输和居中率。结果分析表明，不同的旋转器械或根管扩大设计在颊舌管运输方面没有显著差异（P > 0.05）。在 TruNatomy 组中，TradAC 在 MB 和 ML 管中的居中率较高，而 ConsAC 在远端管中的居中率较高。相反，在 ProTaper Ultimate 组中，ConsAC 显示出更高的 ML 管比率（P < 0.05）。

期刊介绍： he Journal of Dental Sciences (JDS), published quarterly, is the official and open access publication of the Association for Dental Sciences of the Republic of China (ADS-ROC). The precedent journal of the JDS is the Chinese Dental Journal (CDJ) which had already been covered by MEDLINE in 1988. As the CDJ continued to prove its importance in the region, the ADS-ROC decided to move to the international community by publishing an English journal. Hence, the birth of the JDS in 2006. The JDS is indexed in the SCI Expanded since 2008. It is also indexed in Scopus, and EMCare, ScienceDirect, SIIC Data Bases. The topics covered by the JDS include all fields of basic and clinical dentistry. Some manuscripts focusing on the study of certain endemic diseases such as dental caries and periodontal diseases in particular regions of any country as well as oral pre-cancers, oral cancers, and oral submucous fibrosis related to betel nut chewing habit are also considered for publication. Besides, the JDS also publishes articles about the efficacy of a new treatment modality on oral verrucous hyperplasia or early oral squamous cell carcinoma.
