摘要

背景：引导根管治疗有各种各样的应用，其中之一是用于钙化管的协商。最近，制造了一种新的单齿模板，以克服笨重的导轨难以与橡胶坝隔离使用的缺点。目的：本研究旨在通过比较切根管入路（IEA）和单牙模板引导的根管入道（SGEA）之间的物质损失和时间，评估新型单牙模板在三维（3D）打印树脂切牙中治疗牙髓管钙化（PCC）的疗效。方法：选用42颗根尖三分之一有未闭管的树脂切牙（N=21/组）。根据操作员的经验，他们被分为高级牙髓病学家（SE）、研究生（PG）和本科生（UG）（n=7/操作员）。运河是按照国际能源署的惯例进行谈判的，并使用SGEA的单齿模板。根据锥束计算机断层扫描术前和术后的体积差异计算物质损失。所花费的时间也被记录下来。使用的统计分析：使用不配对t检验和单向方差分析检验进行统计分析。结果：SGEA组和IEA组分别有100%和95%的牙齿成功地通过了Canals。SGEA的总体物质损失和所用时间在所有操作员中都显著减少（P<0.001）。在IEA组中，SE和UG之间的物质损失（P<0.05）以及SE-UG和PG-UG之间的所用时间（P<0.05）具有统计学意义。SGEA的两个参数在操作员之间没有显著差异。结论：SGEA显著减少了模拟PCC的3D打印树脂切牙的物质损失和根管协商所需的时间。这与操作员的经验水平无关。

Context background: Guided endodontics has various applications, one of which is for calcified canal negotiation. Recently, a new single-tooth template has been fabricated to overcome the drawbacks of bulky guides, which are difficult to use with rubber dam isolation.

Aim: This study aimed to assess the efficacy of the novel single-tooth template for negotiation of pulp canal calcification (PCC) in three-dimensional (3D)-printed resin incisors by comparing substance loss and time taken between incisal endodontic access (IEA) and single-tooth template-guided endodontic access (SGEA).

Methods: Forty-two resin incisor teeth having patent canal in the apical third were used (N = 21/group). They were subcategorized based on operator's experience into senior endodontist (SE), postgraduate (PG), and undergraduate (UG) (n = 7/operator). Canals were negotiated conventionally for IEA and using the single-tooth template for SGEA. Substance loss was calculated from the volume difference between pre- and postoperative cone-beam computed tomography scans. The time taken was also recorded.

Statistical analysis used: Statistical analysis was performed using unpaired t-test and one-way analysis of variance test.

Results: Canals were successfully negotiated in 100% and 95% of teeth in the SGEA and IEA groups, respectively. Overall substance loss and time taken were significantly lesser for SGEA for all operators (P < 0.001). In the IEA group, post hoc test showed statistical significance between SE and UG for substance loss (P < 0.05) and SE-UG and PG-UG for time taken (P < 0.05). No significant difference among operators was noted for both parameters in SGEA.

Conclusions: SGEA resulted in significantly lesser substance loss and time taken for canal negotiation in 3D-printed resin incisors with simulated PCC. This was independent of the experience levels of the operator.
