Abstract

Aim

The current study aimed to compare the clinical and radiographic success of potassium nitrate in polycarboxylate cement (KNO₃/PCA) compared to mineral trioxide aggregate (MTA) in direct pulp capping (DPC) of carious, immature permanent molars over an 18-month follow-up.

Materials and methods

A two-armed parallel randomised trial included one hundred children with 104 M have been included and assigned equally. The success rate was evaluated clinically and radiographically. Chi-square and Fisher's exact tests were used to compare the clinical and radiographic success rates. The percentage change in radiographic parameters was tested using an independent sample t-test. The effect of time on the mean values of radiographic parameters was tested using the general linear model (GLM). A significant level was set at 5%.

Results

The overall success rates after 18 months of follow-up for KNO₃/PCA and MTA were 90.4% and 92.3%, respectively (p > 0.05). Similarly, root maturation indicators showed no significant difference between the two groups over the follow-up (p > 0.05).

Conclusion

With comparable clinical and radiographic results to MTA, KNO₃/PCA is an effective treatment option in the DPC of carious, immature permanent teeth.

聚羧酸水泥中硝酸钾直接髓盖龋齿，未成熟恒磨牙：一个18个月的随机对照试验

目的：本研究旨在比较硝酸钾聚羧酸盐水泥（KNO3/PCA）与三氧化二矿骨料（MTA）在龋齿、未成熟恒磨牙直接髓盖（DPC）中的临床和影像学成功。材料和方法一项双臂平行随机试验纳入了100名患有104例M的儿童，并被平等分配。通过临床和影像学检查评估成功率。卡方检验和Fisher精确检验用于比较临床和放射学的成功率。采用独立样本t检验检验放射学参数的百分比变化。采用一般线性模型（GLM）检验了时间对射线照相参数平均值的影响。显著水平设为5%。结果随访18个月后，KNO3/PCA和MTA的总成功率分别为90.4%和92.3% (p >；0.05)。同样，在随访期间，两组间的根系成熟指标也没有显著差异(p >；0.05)。结论KNO3/PCA是治疗龋齿、未成熟恒牙DPC的有效方法，临床和影像学结果与MTA相当。
