Pulpotomy is a crucial method to preserve primary teeth until natural exfoliation. This study aimed to evaluate the clinical and radiographic outcomes of pulpotomy with iRoot BP Plus in primary molars and to explore the association between hemostasis time and these outcomes.
Primary molars that underwent iRoot BP Plus pulpotomy and were followed for at least 12 months were selected for this study. Clinical and radiographic data were collected, and the success rate was analyzed in relation to factors such as hemostasis time, tooth type, and arch type. The tests of significance used were the chi-square test, Fisher's exact test, or Kruskal-Wallis test. Statistical significance was set at P < 0.05.
A total of 183 teeth in 106 patients were included in the analysis. The follow-up period fell into a range of 1-3 years, with a mean of 1.6 years. The clinical and radiographic success rates were 96.7% and 92.9%, respectively. The earliest time to observe the radiographic failures was half a year after the treatment, and the latest time was two years after the treatment. Among all the teeth, 130 were recorded with hemostasis time before the application of iRoot BP Plus. Compared to teeth with a hemostasis time of 5 min or less, teeth with a hemostasis time exceeding 5 min showed no significant differences in clinical and radiographic success (P = 1.000 and 0.879). Additionally, neither arch nor teeth type showed a relationship with the pulpotomy success rate (P > 0.05).
Pulpotomy using iRoot BP Plus in primary molars achieved favorable results. The hemostasis time may not significantly impact the outcomes of pulpotomy using iRoot BP Plus in primary molars.
牙髓切断术是保留乳恒牙至自然脱落的重要方法。本研究旨在评估 iRoot BP Plus 在乳磨牙牙髓切断术中的临床和放射学效果，并探讨止血时间与这些效果之间的关系。
选择接受 iRoot BP Plus 牙髓切断术且至少随访 12 个月的乳磨牙进行本研究。收集临床和放射学数据，并根据止血时间、牙齿类型和牙弓类型等因素分析成功率。使用卡方检验、Fisher 确切检验或 Kruskal-Wallis 检验进行显著性检验。统计学显著性水平设为 P < 0.05。
共纳入 106 例患者的 183 颗牙齿进行分析。随访期为 1 至 3 年，平均 1.6 年。临床和放射学成功率分别为 96.7%和 92.9%。最早观察到放射学失败的时间是治疗后半年，最晚时间是治疗后两年。所有牙齿中，有 130 颗记录了在应用 iRoot BP Plus 之前的止血时间。与止血时间在 5 分钟或更短的牙齿相比，止血时间超过 5 分钟的牙齿在临床和放射学成功方面没有显著差异（P=1.000 和 0.879）。此外，牙弓和牙齿类型与牙髓切断术成功率均无关系（P>0.05）。
iRoot BP Plus 在乳磨牙中进行牙髓切断术取得了良好的效果。止血时间可能不会显著影响 iRoot BP Plus 在乳磨牙牙髓切断术中的效果。
