Abstract：
OBJECTIVE: In a tooth with deep dentinal caries; judicious removal of infected dentin and isolating affected dentin from oral fluids with suitable biocompatible material is called indirect pulp therapy (IPT). This randomized clinical trial was done to evaluate and compare the efficacy of Biodentine, Theracal LC and. Dycal as an indirect pulp capping agent in young permanent teeth.
METHODS: IPT was performed in 60 young permanent molars with caries approaching pulp in 55 healthy children using Biodentine, Theracal and Dycal. A 2-3mm layer of GIC was placed over the intervening material followed by restoration of cavity with composite. Clinical and radiographic examinations were conducted at 3 weeks, 3 months, 6 months,12 months, 18 months and 24 months. The data was compared using chi-square test at a significance level of 0.05.
RESULTS: By end of 24 months ,54 teeth presented for follow up with overall success rate of 100% in Theracal, 94.44% in Biodentine, and 77.78% in Dycal. Overall success of Theracal was statistically significant in comparison to Biodentine and Dycal at 24 months follow up (p= 0.03) Conclusions: Radiographic and clinical outcomes of Theracal and Biodentine suggest their use as an alternative material for IPT in young permanent molars with higher success.

摘要：
目的：在有深牙龋的牙齿中，明智地去除受感染的牙本质并使用合适的生物相容性材料从口腔液中分离受影响的牙本质被称为间接牙髓疗法（IPT）。这项随机临床试验是为了评估和比较生物喷丁的疗效，热LC和。Dycal作为年轻恒牙的间接盖髓剂。
方法：使用Biodentine对55名健康儿童的60个龋齿接近牙髓的年轻恒磨牙进行IPT，Theracal和Dycal。将2-3mm的GIC层放置在中间材料上,然后用复合材料修复空腔。在3周进行临床和影像学检查，3个月,6个月,12个月,18个月和24个月。使用卡方检验在0.05的显著性水平下比较数据。
结果：到24个月结束时，54颗牙齿进行随访，Theracal的总体成功率为100％，94.44%的生物牙本质,在Dycal中占77.78%。在24个月的随访中，与Biodentine和Dycal相比，Theracal的总体成功率具有统计学意义（p=0.03）。结论：Theracal和Biodentine的影像学和临床结果表明，Theracal和Biodentine可作为IPT的替代材料用于年轻的永久性磨牙中，成功率更高。
