Calcium hydroxide is the most commonly used material in indirect pulp treatment (IPT). However, its drawbacks required its replacement by other materials.
This study aims to estimate clinically and radiographically the success of indirect pulp treatment of young permanent molars with either photo-activated oral disinfection (PAD) or calcium hydroxide.
This Randomized Controlled Pilot Trial included 32 vital first permanent molars with deep caries that were treated by indirect pulp treatment with either PAD (group 1) or calcium hydroxide (group 2). Clinical and radiographic success in addition to newly-formed dentin thickness were evaluated regularly at 2, 6, 9, and 12 months.
The success for both groups was 100% clinically and radiographically at all follow-up periods. Regarding the mean thickness of newly-formed dentin for both groups at different follow-up periods, there was no statistically significant difference between both groups at 2, 6, 9, and 12 months, with values = 0.825, 0.146, 0.280, and 0.400, respectively.
The clinical and radiographic success for indirect pulp treatment of young permanent molars with both PAD and calcium hydroxide were comparable.
氢氧化钙是间接盖髓术（IPT）中最常用的材料。然而，其缺点使其需要被其他材料所替代。
本研究旨在通过临床和影像学评估光活化口腔消毒（PAD）或氢氧化钙用于年轻恒牙间接盖髓术的成功率。
这项随机对照试验纳入了32颗患有深龋的活髓第一恒磨牙，采用间接盖髓术分别用PAD（第1组）或氢氧化钙（第2组）进行治疗。在2、6、9和12个月定期评估临床和影像学成功率以及新形成牙本质的厚度。
在所有随访期，两组的临床和影像学成功率均为100%。关于两组在不同随访期新形成牙本质的平均厚度，在2、6、9和12个月时两组之间均无统计学显著差异，P值分别为0.825、0.146、0.280和0.400。
PAD和氢氧化钙用于年轻恒牙间接盖髓术的临床和影像学成功率相当。
