Abstract

Background: Locating calcified canals in teeth with pulp canal obliteration remains particularly challenging. The absence of data from randomized controlled trials conducted in vivo has been a critical gap. The objective of this study was to comprehensively assess the accuracy of static-guided endodontics in addressing the challenges of pulp canal obliteration through a randomized controlled clinical trial, as well as pain during treatment and clinical outcomes.

Methods: Eighty patients with pulp canal obliteration were selected from July 2020 to March 2022 and randomly divided into two groups. In the freehand group, patients underwent contemporary freehand access cavity preparation. Patients in the static-guided group underwent innovative access cavity preparation using three-dimensional-printed endodontic guides for precise root canal localization. The quantitative accuracy was subsequently evaluated through meticulous assessment of indirect impression scans obtained from the access cavities. Moreover, pain during treatment and clinical outcome were investigated.

Results: All participants were randomly assigned to treatment groups. The static-guided group showed high accuracy, with average deviations of 0.14 ± 0.08 mm at the coronal entry point, 0.35 ± 0.16 mm at the apical point, and an angular deviation of 1.75 ± 0.30 °. These deviations were significantly lower than those in the freehand group (P < 0.0001). No significant difference were found between the groups regarding pain during treatment and clinical outcomes after one year (P > 0.05).

Conclusion: This study demonstrates, within its limitations, the static endodontics guides represent an accurate method in locating root canals for pulp canal obliteration through a randomized controlled clinical trial.

静态引导牙髓治疗牙髓管闭塞预备通道腔的准确性：一项随机对照临床试验。

背景：牙髓管闭塞术中钙化牙管的定位仍然具有挑战性。缺乏在体内进行的随机对照试验的数据是一个关键的空白。本研究的目的是通过一项随机对照临床试验，全面评估静态引导牙髓学在解决髓管闭塞挑战方面的准确性，以及治疗过程中的疼痛和临床结果。方法：选择2020年7月~ 2022年3月行髓管闭塞术的患者80例，随机分为两组。在徒手组，患者进行当代徒手通道腔准备。静态引导组采用三维打印根管导具进行创新的根管预备，实现根管的精确定位。定量准确性随后通过细致的评估间接印象扫描从通道腔获得评估。此外，还对治疗过程中的疼痛和临床结果进行了调查。结果：所有参与者随机分为治疗组。静态导引组具有较高的准确度，冠状入口点的平均偏差为0.14±0.08 mm，根尖点的平均偏差为0.35±0.16 mm，角偏差为1.75±0.30°。这些偏差均显著低于徒手组（p0.05）。结论：本研究通过一项随机对照临床试验，在其局限性下，静态牙髓学导具是一种定位根管进行髓管闭塞的准确方法。试验注册：中国临床试验注册中心，NO。ChiCTR2000037260（27/08/2020，回顾性注册）。
