The purpose of this study was to compare the clinical and radiographic success of Biodentine™ and mineral trioxide aggregate (MTA) pulpotomy in primary molars.
Thirty-two four- to nine-year-olds were included in this study. The primary molars were randomly assigned to the Biodentine™ and MTA groups. After coronal pulp removal and hemostasis, the remaining pulp tissue was covered with Biodentine™ or MTA. All teeth were restored with stainless steel crowns. Clinical and radiographic successes and failures were recorded at six-, 12-, 18- and 24-month follow-ups. Data were statistically analyzed using Mann-Whitney U and Wilcoxon tests.
The 24-month follow-up evaluations revealed that the clinical success rates were 96.8 percent (30 out of 31) for both Biodentine™ and MTA. The radiographic success rates at 24 months were 93.6 percent (29 out of 31) for Biodentine™ and 87.1 percent (27 out of 31) for MTA. No significant differences were found among the groups at all follow-up appointments (P>0.05) Conclusion: Biodentine™ and mineral trioxide aggregate did not differ significantly in combined clinical and radiographic success after 24 months.
本研究旨在比较Biodentine™和三氧化矿物凝聚体（MTA）在乳磨牙活髓切断术中的临床和影像学成功率。
本研究纳入了32名4至9岁的儿童。将乳磨牙随机分为Biodentine™组和MTA组。在去除冠髓并止血后，用Biodentine™或MTA覆盖剩余的牙髓组织。所有牙齿均用不锈钢冠修复。在6个月、12个月、18个月和24个月的随访中记录临床和影像学的成功与失败情况。使用曼-惠特尼U检验和威尔科克森检验对数据进行统计学分析。
24个月的随访评估显示，Biodentine™组和MTA组的临床成功率均为96.8%（31颗牙中的30颗）。Biodentine™在24个月时的影像学成功率为93.6%（31颗牙中的29颗），MTA为87.1%（31颗牙中的27颗）。在所有随访时间点，两组之间均未发现显著差异（P>0.05）。结论：24个月后，Biodentine™和三氧化矿物凝聚体在临床和影像学综合成功率方面无显著差异。
