BACKGROUND/PURPOSE: Diode laser is widely used in dentistry, especially on treating soft tissues. Currently neither the effect of diode laser pulpotomy nor its comparison with formocresol (FC) pulpotomy has been fully investigated. Therefore the purpose of this study was to investigate the clinical and radiographic outcomes of diode laser pulpotomy and formocresol pulpotomy on human primary molars.
Healthy two-to eight-year-olds were treated with pulpotomies on primary molars as part of their regular dental treatment. The pulpotomy teeth were randomly assigned into one of two groups. The experimental group was treated with diode laser; the control group was treated with 1:5 dilution FC.
Forty-five teeth with diode laser and 45 teeth with FC in 70 healthy children were studied. In 12 months follow-up, the clinical success rates were 92.9%, and 90.9% for laser and FC respectively, and the radiographic success rates were 78.6%, and 72.7% for laser and FC respectively. Conclusion: There is no significant difference of clinical and radiographic success rate between diode laser and FC pulpotomy in human primary molars followed for 12 months.
背景/目的：二极管激光在牙科领域应用广泛，尤其用于软组织治疗。目前，二极管激光牙髓切断术的效果及其与甲醛甲酚（FC）牙髓切断术的比较均未得到充分研究。因此，本研究旨在探讨二极管激光牙髓切断术和甲醛甲酚牙髓切断术治疗人类乳磨牙的临床及影像学效果。
健康的2至8岁儿童在其常规牙科治疗中接受乳磨牙牙髓切断术。将接受牙髓切断术的牙齿随机分为两组。实验组采用二极管激光治疗；对照组采用1:5稀释的FC治疗。
对70名健康儿童的45颗接受二极管激光治疗的牙齿和45颗接受FC治疗的牙齿进行了研究。在12个月的随访中，激光治疗组和FC治疗组的临床成功率分别为92.9%和90.9%，影像学成功率分别为78.6%和72.7%。结论：在对人类乳磨牙进行12个月的随访中，二极管激光牙髓切断术和FC牙髓切断术的临床及影像学成功率无显著差异。
