This study aimed to compare the clinical and radiographic effectiveness of Low Level Laser Therapy in vital pulp of human primary teeth.
Sixty mandibular primary molars of children aged between 5-9 years were assigned into four groups: Diluted Formocresol (FC), Calcium Hydroxide (CH), Low Level Laser Therapy (LLLT) and Calcium Hydroxide preceded by Low Level Laser Therapy (LLLT + CH). The clinical and radiographic evaluations were performed at 6, 12 and 18 post-operative months.
All the groups studied were successful in the clinical evaluation over the follow-up period. At 6 months, the radiographic success rate for FC group was 100%, 60% for CH group, 80% for LLLT group and 85.7% for LLLT + CH group. After 12 months, the radiographic success rate was 100% for FC group, 50% for CH group, 80% for LLLT group and 78.6% for LLLT + CH group. At the 18 months follow-up, 100% of the FC group, 66.7% of CH group, 73.3% of the LLLT group and 75% of the LLLT + CH group.
These findings suggest that Low Level Laser Therapy may be considered as an adjuvant alternative for vital pulp therapy on human primary teeth. Low Level Laser Therapy preceding the use of calcium hydroxide showed satisfactory results.
本研究旨在比较低强度激光疗法对人类乳牙髓的临床和影像学疗效。
将60颗5至9岁儿童的下颌乳磨牙分为四组：稀释甲醛甲酚（FC）、氢氧化钙（CH）、低强度激光疗法（LLLT）以及先进行低强度激光疗法再使用氢氧化钙（LLLT + CH）。在术后6、12和18个月进行临床和影像学评估。
在随访期间，所有研究组在临床评估中均取得成功。6个月时，FC组的影像学成功率为100%，CH组为60%，LLLT组为80%，LLLT + CH组为85.7%。12个月后，FC组的影像学成功率为100%，CH组为50%，LLLT组为80%，LLLT + CH组为78.6%。在18个月的随访中，FC组为100%，CH组为66.7%，LLLT组为73.3%，LLLT + CH组为75%。
这些发现表明，低强度激光疗法可被视为人类乳牙髓活力治疗的辅助替代方法。在使用氢氧化钙之前进行低强度激光疗法显示出令人满意的结果。
