Complete pulpotomy is the removal of the coronal portion of a vital pulp and is a means of preserving the vitality of the remaining root portion. The objective of this study was to evaluate the 12-months success rate of complete pulpotomy with Biodentine on mature permanent molars with signs and symptoms of symptomatic irreversible pulpitis.
A total of 68 molars diagnosed with symptomatic irreversible pulpitis in 68 patients aged 20 years and older were included in this study. The exclusion criteria were intraoperative clinical signs of pulp necrosis on the molar to be treated such as no bleeding, or uncontrollable pulp hemorrhage (more than 5 minutes of hemostasis) on at least 1 canal. A complete pulpotomy with Biodentine was performed on molars with symptomatic irreversible pulpitis by the same operator and with the same protocol. A 12-months postoperative follow-up was conducted to evaluate clinical and radiologic success.
A total of 66 patients received complete pulpotomy; 52 could be examined 12 months postoperatively. Clinical and radiologic analysis at 12 months postoperatively revealed a success rate of 87% (45 of 52 molars) and a failure rate of 13% (7 of 52 molars). There was a relationship between age, tooth type, and preoperative periapical condition and treatment success with P < .05.
Compliance with the indications and protocol for complete pulpotomy with Biodentine on mature permanent molars with symptomatic irreversible pulpitis gives positive results at the 12-month follow-up.
完全活髓切除术是切除有活力牙髓的冠部，是保留剩余根部活力的一种方法。本研究的目的是评估 Biodentine 用于有症状不可复性牙髓炎的成熟恒磨牙的完全活髓切除术的 12 个月成功率。
本研究共纳入 68 名年龄在 20 岁及以上的患者的 68 颗诊断为有症状不可复性牙髓炎的磨牙。排除标准为术中磨牙治疗牙有牙髓坏死的临床迹象，如无出血或至少 1 个根管的不可控性牙髓出血（止血时间超过 5 分钟）。对有症状不可复性牙髓炎的磨牙采用同一术者和相同方案行完全活髓切除术，并用 Biodentine 覆盖。术后 12 个月进行随访，评估临床和放射学疗效。
共有 66 名患者接受了完全活髓切除术，其中 52 名患者可在术后 12 个月进行检查。术后 12 个月的临床和放射学分析显示成功率为 87%（52 颗磨牙中的 45 颗），失败率为 13%（52 颗磨牙中的 7 颗）。年龄、牙位、术前根尖状况与治疗成功率之间存在关系，P<.05。
对于有症状不可复性牙髓炎的成熟恒磨牙，在符合 Biodentine 完全活髓切除术的适应证和方案的情况下，12 个月的随访结果为阳性。
