This clinical study aimed to assess the impact of utilizing loupes and dental operating microscopes (DOM) with varying magnifications on the success of class II direct composite restorations.
A total of 130 class II, moderately deep caries teeth from 85 patients were randomly assigned to four groups: naked eye, ×3 loupe, ×5 loupe, and ×8.5 DOM. Cavities were restored with or without magnification. The restorations were evaluated according to World Dental Federation criteria at 1, 6, and 12-month intervals by previously calibrated evaluators. Cochran's Q test was used to compare paired scores across three or more time points within groups, while the Friedman test was employed to compare scores at three or more time points. Multiple comparisons were adjusted using the Bonferroni correction. The significance level was set at p < 0.05.
Statistical analysis revealed no significant differences among the groups at the 1-, 6-, and 12-month follow-up periods (p > 0.05). Although not statistically significant, the magnified groups exhibited higher scores in aesthetic anatomical form, proximal form, postoperative sensitivity, periodontal response, and adjacent mucosalcriteria compared to the naked eye group.
Although no statistically significant difference was observed at the 12-month follow-up between restorations performed with and without magnification, the groups using magnification showed higher scores.
本临床研究旨在评估使用不同放大倍数的放大镜和牙科手术显微镜（DOM）对Ⅱ类直接复合树脂修复成功率的影响。
将来自85名患者的130颗Ⅱ类中度深龋牙齿随机分为四组：肉眼组、×3放大镜组、×5放大镜组和×8.5 DOM组。在有或没有放大设备的情况下进行窝洞修复。由预先校准的评估人员按照世界牙科联盟标准在1个月、6个月和12个月时对修复体进行评估。采用 Cochr an's Q检验比较组内三个或更多时间点的配对分数，同时采用Friedman检验比较三个或更多时间点的分数。使用Bonferroni校正进行多重比较。显著性水平设定为p < 0.05。
统计分析显示，在1个月、6个月和12个月的随访期内，各组之间无显著差异（p > 0.05）。尽管无统计学意义，但与肉眼组相比，放大组在美学解剖形态、邻面形态、术后敏感性、牙周反应和相邻黏膜标准方面的得分更高。
尽管在12个月随访时，有放大设备和无放大设备的修复体之间未观察到统计学上的显著差异，但使用放大设备的组得分更高。
