摘要

目的：本横断面研究分析和比较牙科学生进行不同修复手术（修复或置换）的治疗时间。材料和方法：本研究采用随机对照试验（ccia）患者的辅助数据。作业时间（以分钟为单位）由作业人员/助手监控，作业时间为2016年至2022年。作业人员在作业过程中的水平分为第3年、第4年和第5年。由于手术时间非正态分布，采用非参数检验：两组比较采用Mann-Whitney U（修复 × 置换），跨学生年级比较采用Kruskal-Wallis，当p < 0.05时采用bonferroni校正的两两Mann-Whitney检验；还计算了平均值的95%置信区间。结果：共分析117例手术：修复76例（平均110.2±29.4 min），置换41例（平均128.4±30.9 min）。磨牙修复平均109.2±32.0 min，磨牙置换平均130.9±34.4 min，差异有统计学意义（p = 0.015）。修复前磨牙平均112.2±23.8 min，替换前磨牙平均122.5±20.1 min，差异无统计学意义（p = 0.248）。第三、四、五组学生之间的比较表明，在修复（p = 0.001）和替换（p = 0.012）次数上存在显著差异，最后一年的学生完成手术的速度更快。结论：修复所需的时间明显少于替换，尤其是磨牙。此外，不同学术水平的学生所需时间的差异强调了技术技能和经验在减少程序持续时间方面的相关性。临床相关性：本研究强调了修复在牙科修复中优于替代的临床优势，特别是在时间效率方面。修复不仅需要比替换更少的时间，特别是磨牙，而且通过保留牙齿结构符合微创牙科的原则。

Comparison of treatment times for repair and replacement: A cross-sectional study

Objective

This cross-sectional study analyzed and compared the treatment time for dental students to perform different restorative procedures (repair or replacement).

Material and methods

This study used secondary data from patients treated in a randomized controlled trial (CaCIA). The time (in minutes) was monitored by the operators/assistants, performed between 2016 and 2022. The operator's level during the procedures was categorized into third, fourth, and fifth years. Since procedure times were not normally distributed, non-parametric tests were applied: Mann-Whitney U for two-group comparisons (repair × replacement) and Kruskal–Wallis for comparisons across student years, followed by Bonferroni-adjusted pairwise Mann-Whitney tests when p < 0.05; 95 % confidence intervals for means were also calculated.

Results

A total of 117 procedures were analyzed: 76 repairs (mean 110.2 ± 29.4 min) and 41 replacements (mean 128.4 ± 30.9 min). Repairs in molars averaged 109.2 ± 32.0 min, while replacements in molars averaged 130.9 ± 34.4 min, showing a significant difference (p = 0.015). Repairs averaged 112.2 ± 23.8 min for premolars, while replacements averaged 122.5 ± 20.1 min, with no significant difference observed (p = 0.248). Comparisons between third, fourth, and fifth student groups demonstrated significant differences in repair (p = 0.001) and replacement (p = 0.012) times, with final year students completing procedures faster.

Conclusion

Repairs require significantly less time than replacements, particularly for molars. Additionally, the variation in time required by students from different academic levels underscores the relevance of technical skills and experience in reducing procedural duration.

Clinical relevance

This study highlights the clinical advantages of repair over replacement in restorative dentistry, particularly regarding time efficiency. Repairs not only require less time than replacements, especially for molars, but also align with the principles of minimally invasive dentistry by preserving tooth structure.

期刊介绍： The Journal of Dentistry has an open access mirror journal The Journal of Dentistry: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review. The Journal of Dentistry is the leading international dental journal within the field of Restorative Dentistry. Placing an emphasis on publishing novel and high-quality research papers, the Journal aims to influence the practice of dentistry at clinician, research, industry and policy-maker level on an international basis. Topics covered include the management of dental disease, periodontology, endodontology, operative dentistry, fixed and removable prosthodontics, dental biomaterials science, long-term clinical trials including epidemiology and oral health, technology transfer of new scientific instrumentation or procedures, as well as clinically relevant oral biology and translational research. The Journal of Dentistry will publish original scientific research papers including short communications. It is also interested in publishing review articles and leaders in themed areas which will be linked to new scientific research. Conference proceedings are also welcome and expressions of interest should be communicated to the Editor.
