The purpose of this study was to assess and compare the clinical and radiographic success rates of low-level laser therapy (LLLT) and formocresol (FC) for pulpotomy in primary teeth. Utilizing a split-mouth technique, 106 primary molars of 36 five- to eight-year-olds were included. The teeth were selected according to specific clinical and radiographic inclusion criteria and randomly assigned to the LLLT group and FC group. A pulpotomy was performed on each molar; 53 teeth were treated with LLLT, and 53 teeth were treated using FC. Children were followed at six and 12 months for clinical and radiographic evaluation. At six months, the clinical success rate was 98 percent for each group. Radiographic success was 100 percent for the LLLT group and 98 percent for the FC group. At 12 months, both groups showed a clinical success of 96.1 percent. Radiographic success at 12 months was 100 percent and 98 percent for LLLT and FC, respectively. Both low-level laser therapy and formocresol pulpotomy techniques showed favorable clinical and radiographic outcomes in human primary molar teeth over 12 months. Further longitudinal studies with longer follow-up periods and larger sample sizes are encouraged.
本研究的目的是评估和比较低强度激光治疗（LLLT）和甲醛甲酚（FC）用于乳牙牙髓切断术的临床成功率和影像学成功率。采用双侧对照技术，纳入了36名5至8岁儿童的106颗乳磨牙。根据特定的临床和影像学纳入标准选择牙齿，并随机分为LLLT组和FC组。对每颗磨牙进行牙髓切断术；53颗牙齿接受LLLT治疗，53颗牙齿接受FC治疗。在6个月和12个月时对儿童进行临床和影像学评估。6个月时，每组的临床成功率均为98%。LLLT组的影像学成功率为100%，FC组为98%。12个月时，两组的临床成功率均为96.1%。12个月时，LLLT和FC的影像学成功率分别为100%和98%。在12个月的时间里，低强度激光治疗和甲醛甲酚牙髓切断术技术在人类乳磨牙中均显示出良好的临床和影像学效果。鼓励进行更长随访期和更大样本量的进一步纵向研究。
