Laser photobiomodulation (LPBM), also called Low Level Laser Therapy (LLLT), has shown potential to reduce the pulpal inflammation and to preserve the dental pulp vitality, thereby improving healing. Lasers being minimally invasive, safe, and patient friendly prompt its application in pediatric dentistry.
The aim of this study was to evaluate and compare the clinical and radiographic success rates of LPBM and formocresol pulpotomy at 9 months post intervention in human primary molars.
A randomized controlled, split-mouth study design was followed involving children aged 4-7 years with at least two primary molars indicated for pulpotomy. Sixty-eight eligible primary molars were randomly allocated to two interventions - formocresol pulpotomy (Group I) and LPBM pulpotomy (Group II).
Chi-square test was used for statistical analysis fixing significance level at P ≤ 0.05.
There was no statistically significant difference in the clinical success rates between the formocresol group (97.05%) and the photobiomodulation group (94.1%) (χ = 0.34, P = 0.55); however, the radiographic success rate was significantly high in the laser group (94.1%) compared to the formocresol group (58.82%) (χ = 11.76, P = 0.001).
LPBM could be a viable nonpharmaceutical alternative for formocresol pulpotomy in human primary teeth.
激光光生物调节（LPBM），也称为低水平激光疗法（LLLT），已显示出减少牙髓炎症和保存牙髓活力的潜力，从而改善愈合。由于激光具有微创、安全和对患者友好的特点，因此它在儿科牙科中的应用得到了推广。
本研究旨在评估和比较 LPBM 和福尔可定牙髓切断术在干预后 9 个月对人乳磨牙的临床和放射成功率。
采用随机对照、分口设计，纳入年龄在 4-7 岁、至少有两颗乳磨牙需要牙髓切断术的儿童。68 颗符合条件的乳磨牙被随机分配到两种干预措施-福尔可定牙髓切断术（I 组）和 LPBM 牙髓切断术（II 组）。
采用卡方检验进行统计分析，置信水平设为 P≤0.05。
福尔可定组（97.05%）和光生物调节组（94.1%）的临床成功率无统计学差异（χ=0.34，P=0.55）；然而，激光组的放射成功率显著高于福尔可定组（58.82%）（χ=11.76，P=0.001）。
LPBM 可能是人类乳磨牙福尔可定牙髓切断术的一种可行的非药物替代方法。
