BACKGROUND
Calcium silicate-based materials have become widely used in recent years due to their positive effect on pulp cells, which stimulate tertiary dentin formation.
AIM
The aim of the present study was to evaluate and compare clinically and radiographically the performance of MTA and Biodentine as pulp-dressing materials following pulpotomy in primary molars at 24-month follow-up.
DESIGN
Molars from patients aged 4-9 years scheduled for pulpotomy were treated with either MTA or Biodentine followed by a stainless-steel crown. These molars were clinically and radiographically followed up at 6, 12, 18, and 24 months. Statistical analysis was performed to detect differences between the two groups.
RESULTS
A total of 84 pulpotomies were performed obtaining a total success rate of 99.4 and 97.2% for Biodentine and MTA, respectively, at 24 months, showing no statistically significant differences between the two groups.
CONCLUSION
24-month follow-up showed that Biodentine and MTA have similar effectiveness.
背景
近年来，硅酸钙基材料因其对牙髓细胞有积极作用，能刺激第三期牙本质形成而被广泛应用。
目的
本研究的目的是在24个月的随访期内，对乳牙活髓切断术后使用MTA和生物陶瓷作为牙髓盖髓材料的临床和影像学表现进行评估和比较。
设计
对4至9岁计划进行活髓切断术的患者的磨牙，分别用MTA或生物陶瓷治疗，然后戴上不锈钢冠。这些磨牙在6、12、18和24个月时进行临床和影像学随访。进行统计分析以检测两组之间的差异。
结果
共进行了84次活髓切断术，24个月时生物陶瓷和MTA的总成功率分别为99.4%和97.2%，两组之间无统计学显著差异。
结论
24个月的随访表明，生物陶瓷和MTA具有相似的有效性。
