INTRODUCTION
The preservation of the integrity and health of primary teeth and their supporting tissues is of great importance in maintaining arch length space, mastication, speech, and esthetics. A pulpotomy is a common therapy performed on a primary tooth presenting reversible pulpitis or a traumatic pulp exposure, allowing its conservation on the arch until its loss.
AIM
The study aims to clinically and radiographically evaluate the rates of success and efficacy of Biodentine™ as pulpotomy medicament exclusively on deciduous molars with complete roots formation (stage 2).
MATERIALS AND METHODS
A total number of 75 primary molars in stage 2 of formation were selected to undergo pulpotomy treatment. All teeth were restored with a stainless-steel crown.The clinical success was evaluated at 1, 3, 6 and 12-month intervals. The radiographic follow-up evaluations were at 6 and 12 months. The resulting data were tabulated and statistically analyzed.
RESULTS
Among the 75 teeth treated with Biodentine™, one tooth revealed abnormal mobility and tenderness to percussion at the end of the 1st month. PLS widening and the bone lesion was not seen in any of the 74 remaining cases. Forty teeth (54.1%) showed pulp canal obliteration (PCO), and none of the cases developed a draining sinus or had increased mobility. At the end of the 1-year follow-up, the clinical and radiographic success rates were 98.7% and 100%, respectively.
CONCLUSION
Pulpotomies performed with Biodentine™ on stage 2 primary molars were generally very satisfactory and fulfilled all requirements, covering all needs. This innovative bioactive medicament seems to be a "heroic" material. The excellent outcomes of the present study are indicative that Biodentine™ is a promising biomaterial to promote pulp repair after pulpotomy in clinical practice.

引言
乳牙及其支持组织的完整性和健康对于维持牙弓长度、咀嚼、言语和美观非常重要。牙髓切断术是对出现可逆性牙髓炎或外伤性牙髓暴露的乳牙进行的一种常见治疗方法，可使其在牙弓上保留至脱落。
目的
本研究旨在通过临床和影像学评估Biodentine™作为牙髓切断术药物专门用于牙根完全形成（第2阶段）的乳牙磨牙的成功率和疗效。
材料与方法
选择75颗处于形成第2阶段的乳牙磨牙进行牙髓切断术治疗。所有牙齿均用不锈钢冠修复。在1、3、6和12个月的间隔时间进行临床成功评估。影像学随访评估在6个月和12个月时进行。将所得数据制成表格并进行统计分析。
结果
在75颗用Biodentine™治疗的牙齿中，1颗牙齿在第1个月末显示出异常松动和叩诊疼痛。其余74例中均未发现牙周膜增宽和骨病变。40颗牙齿（54.1%）显示牙髓腔闭塞（PCO），且无一例出现引流窦或松动增加。在1年随访结束时，临床和影像学成功率分别为98.7%和100%。
结论
用Biodentine™对第2阶段乳牙磨牙进行的牙髓切断术总体上非常令人满意，满足所有要求，涵盖所有需求。这种创新的生物活性药物似乎是一种“神奇”的材料。本研究的优异结果表明，Biodentine™是临床实践中牙髓切断术后促进牙髓修复的一种有前途的生物材料。
