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.
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。
