The purpose of this study was to evaluate the clinical and radiographic success rates of mineral trioxide aggregate partial pulpotomy (PP) compared to formocresol pulpotomy (FP) in human primary molars.
In this randomized, controlled, split-mouth, clinical trial, 25 healthy five- to eight-year-olds, with 50 carious primary mandibular second molars lacking clinical and radiographic evidence of pulp pathology, were selected. The selected teeth were randomly assigned into two groups, PP and FP, for vital pulp therapy. Stainless steel crowns were placed as final restorations for both groups. Clinical and radiographic evaluation at six, 12, and 24 months used the following criteria for failure: pain; swelling; sinus tract; mobility; internal or external root resorption; furcation or periapical radiolucency; and widening of periodontal ligament space. The data were analyzed using a binary logistic generalized estimating equation model.
At the 12-month and 24-month follow-ups, one child and three children, respectively, were lost to follow-up. At the 24-month follow-up, the clinical, radiographic, and overall success rates of PP were 90.9 percent, 90.5 percent, and 81.8 percent versus FP success of 100 percent, 95.2 percent, and 95.2 percent, respectively.
There were no significant differences between clinical, radiographic, and overall success rate of mineral trioxide aggregate partial pulpotomy and formocresol pulpotomy overall 24 months.
本研究旨在评估在人类乳磨牙中，与甲醛甲酚牙髓切断术（FP）相比，三氧化矿物凝聚体部分牙髓切断术（PP）的临床和影像学成功率。
在这项随机、对照、双侧对照的临床试验中，选取了25名5至8岁的健康儿童，他们共有50颗患有龋齿的下颌第二乳磨牙，且无牙髓病变的临床和影像学证据。将所选牙齿随机分为两组，即PP组和FP组，进行活髓治疗。两组均采用不锈钢冠作为最终修复体。在6个月、12个月和24个月时进行临床和影像学评估，失败标准如下：疼痛；肿胀；窦道；松动；牙根内吸收或外吸收；根分叉或根尖周透射影；以及牙周膜间隙增宽。使用二元逻辑广义估计方程模型对数据进行分析。
在12个月和24个月的随访中，分别有1名儿童和3名儿童失访。在24个月的随访中，PP组的临床、影像学和总体成功率分别为90.9%、90.5%和81.8%，而FP组的成功率分别为100%、95.2%和95.2%。
在24个月的总体观察中，三氧化矿物凝聚体部分牙髓切断术与甲醛甲酚牙髓切断术在临床、影像学和总体成功率方面无显著差异。
