Pulpotomy is a procedure in which part of an exposed vital pulp is removed, usually as a means of preserving the vitality and function of the remaining part.
The aim is to compare the effectiveness of Dycal (CH), EndoSequence, and Titanium-prepared platelet-rich fibrin with EndoSequence (T-PRF) as pulpotomy agents in mature permanent molars with irreversible pulpitis.
Sixty permanent mandibular molars with carious exposure and symptoms of irreversible pulpitis were randomly allocated to three groups.
Full pulpotomy was performed using Dycal, EndoSequence, and T-PRF with EndoSequence as pulpotomy agents. Pain intensity was analyzed using a Numeric Rating Scale score at baseline 24 h, 7 days, 6 months, and 1 year. The clinical and radiographic evaluations were done at 6 months and 1 year.
Nonparametric tests (Kruskal-Wallis, Chi-square) were applied to analyze the data as the normality test does not follow a normal distribution.
T-PRF and EndoSequence showed effective results when compared clinically, and there was no significant difference between radiographic success rates among the three groups at ( = 0.325 at 6 months, 0.466 at 12 months) follow-up.
T-PRF and EndoSequence showed higher success rates among Dycal, EndoSequence as pulpotomy agents in teeth with irreversible pulpitis.
活髓切断术是一种切除部分暴露的牙髓的手术,通常作为保留剩余牙髓活力和功能的一种手段。
比较Dycal(氢氧化钙)、EndoSequence以及含钛富血小板纤维蛋白联合EndoSequence(T-PRF)作为活髓切断术药物用于治疗患有不可逆性牙髓炎的成熟恒牙的有效性。
将60颗患有龋洞暴露且有不可逆性牙髓炎症状的下颌恒牙随机分为三组。
分别使用Dycal、EndoSequence以及T-PRF联合EndoSequence作为活髓切断术药物进行全髓切断术。使用数字评分量表在基线、24小时、7天、6个月和1年时分析疼痛强度。在6个月和1年时进行临床和影像学评估。
由于正态性检验不服从正态分布,因此应用非参数检验(Kruskal-Wallis检验、卡方检验)来分析数据。
在临床比较中,T-PRF和EndoSequence显示出有效的结果,在随访6个月(χ² = 0.325)和12个月(χ² = 0.466)时,三组之间的影像学成功率没有显著差异。
在患有不可逆性牙髓炎的牙齿中,T-PRF和EndoSequence作为活髓切断术药物在Dycal、EndoSequence中显示出更高的成功率。
