This trial was designed to evaluate the clinical and radiographic success rates of calcium-enriched mixture (CEM) cement with and without low level laser therapy (LLLT) and compare them to that of formocresol (FC) and ferric sulfate (FS) in primary molar pulpotomies.
This randomized clinical trial was conducted on a total of 160 teeth selected from 40 patients aged 3-9 years. Patients with at least four primary molars needing pulpotomy, were included in order to have each tooth assigned randomly in one of the four following groups; FC, FS, CEM, and LLLT/CEM. Six- and twelve-month follow-up periods were conducted in order to enable a clinical and radiographic evaluation of the treated teeth. Collected data were analyzed using Cochran Q Tests.
The 12-month clinical success rate for each technique was: FC=100%, FS=95%, CEM=97.5% and LLLT/CEM=100% with no significant differences (>0.05). Furthermore, 12-month radiographic success rate for each technique was: FC=100%, FS=92.5%, CEM=95% and LLLT/CEM=100% with no significant differences (>0.05).
Favorable outcomes of four treatment techniques in pulpotomy of primary molar teeth were comparable. CEM with/without LLLT may be considered as a safe and successful pulpotomy treatment modality compared to current conventional methods.
本试验旨在评估在乳牙牙髓切断术中，使用和不使用低强度激光治疗（LLLT）的富钙混合物（CEM）水门汀的临床和影像学成功率，并将其与甲酚甲醛（FC）和硫酸铁（FS）的成功率进行比较。
本随机临床试验共纳入了40名3至9岁患者的160颗牙齿。纳入至少有四颗需要进行牙髓切断术的乳牙的患者，以便将每颗牙齿随机分配到以下四组之一：FC组、FS组、CEM组和LLLT/CEM组。进行了6个月和12个月的随访，以便对治疗后的牙齿进行临床和影像学评估。使用 Cochr an Q检验对收集的数据进行分析。
每种技术的12个月临床成功率分别为：FC组=100%，FS组=95%，CEM组=97.5%，LLLT/CEM组=100%，差异无统计学意义（>0.05）。此外，每种技术的12个月影像学成功率分别为：FC组=100%，FS组=92.5%，CEM组=95%，LLLT/CEM组=100%，差异无统计学意义（>0.05）。
乳牙牙髓切断术中四种治疗技术的良好效果相当。与目前的传统方法相比，使用或不使用LLLT的CEM可被视为一种安全且成功的牙髓切断术治疗方式。
