The most frequently used and universally accepted technique for removing caries is mechanical ablation of decayed tissues by rotating drills. New minimally invasive strategies, such as the use of lasers to perform highly controlled tissue ablation, have been introduced in dental practice. The aim of this study was to assess and compare treatment with a 2940 nm erbium/yttrium-aluminum-garnet (Er:YAG) laser versus a conventional rotary treatment during cavity preparation in children with regard to restoration integrity. In a randomized, controlled, blinded trial using a split-mouth design, 40 (9-12-year-old) children with 80 carious primary molars were included. The cavity in one quadrant was randomized to be treated conventionally using a bur, while the cavity in the other quadrant was prepared using an Er:YAG laser. At the one-year follow-up, clinical examinations were conducted to assess the integrity of the restorations according to the Ryge criteria. The data were analyzed using SPSS version 22 (IBM Inc., Chicago, IL, USA). The average age of the participants was 9.4 ± 1.29 years. Males accounted for 51.4% of the participants. The Ryge criteria showed clinical success of restorations, and there was no discernible difference between the conventional and laser intervention techniques. Over one year, no statistically significant differences in the clinical integrity based on the Ryge criteria were found following class I cavity preparation in primary teeth with either procedure.
去除龋齿最常用且被普遍接受的技术是使用旋转牙钻对龋坏组织进行机械性磨除。牙科实践中已引入了新的微创策略，比如使用激光进行高度可控的组织磨除。本研究的目的是评估和比较在儿童龋洞预备过程中，使用2940纳米铒/钇铝石榴石（Er:YAG）激光治疗与传统旋转治疗在修复体完整性方面的差异。在一项采用半口设计的随机、对照、双盲试验中，纳入了40名（9至12岁）患有80颗龋坏乳磨牙的儿童。一个象限的龋洞随机采用牙钻进行传统治疗，而另一个象限的龋洞则使用Er:YAG激光进行预备。在一年的随访中，根据Ryge标准进行临床检查以评估修复体的完整性。使用SPSS 22版软件（美国伊利诺伊州芝加哥市IBM公司）对数据进行分析。参与者的平均年龄为9.4±1.29岁。男性占参与者的51.4%。Ryge标准显示修复体临床成功，传统治疗技术与激光干预技术之间没有明显差异。在一年时间里，对于乳牙I类洞预备，两种治疗方法在基于Ryge标准的临床完整性方面均未发现统计学上的显著差异。
