The purpose of this study was to compare pediatric dental residents' comfort levels and cavity preparation time using an Er, Cr:YSGG laser versus a conventional high-speed handpiece.
This cross-sectional study was conducted on residents with no past restorative dental laser experience. A mixed-effects model was used to evaluate the difference in total time and comfort level between the laser and high-speed handpiece groups.
A total of 131 teeth (high-speed handpiece group equals 79; laser group equals 52) were completed. The adjusted result showed that the estimated average difference in preparation time among the laser group was 1.92 minutes longer per tooth compared to the high-speed handpiece group. Similarly, when using a laser, residents had a 0.74 times lower rate of comfort compared to the high-speed handpiece group.
The total preparation time required for restorative treatment with a laser was significantly higher than the total time with a high-speed handpiece. Additionally, the comfort level was also lower using a laser compared to a high-speed preparation.
本研究旨在比较儿科牙科住院医师使用铒铬：钇铝石榴石激光（Er, Cr:YSGG激光）和传统高速手机时的舒适度及窝洞预备时间。
本横断面研究针对既往无牙科修复激光经验的住院医师开展。采用混合效应模型评估激光组和高速手机组在总时间和舒适度上的差异。
共完成131颗牙齿的治疗（高速手机组79颗；激光组52颗）。校正结果显示，与高速手机组相比，激光组每颗牙齿的预备时间估计平均差异长1.92分钟。同样，使用激光时，住院医师的舒适度比高速手机组低0.74倍。
激光修复治疗所需的总预备时间显著高于高速手机的总时间。此外，与高速预备相比，使用激光时的舒适度也较低。
