BACKGROUND/PURPOSE: Pulpotomy is the amputation of coronally infected pulp tissue to maintain the vitality and function of the radicular pulp. This study was designed to assess the clinical and radiographic success rates of primary molars treated by pulpotomy using diode laser, sodium hypochlorite, or no medication after a follow-up period of 24 months.
A retrospective study was conducted by evaluating the success rates of primary molars treated by pulpotomy with diode laser, sodium hypochlorite, or no medication according to the clinical symptoms and signs and radiographic features.
There were 145 primary molars included in the study. No significant differences in clinical and radiographic success rates were found among primary molars treated by pulpotomy using diode laser, sodium hypochlorite, or no medication, when the teeth were treated by experienced pedodontists and restored with stainless steel crowns. The 2-year clinical success rates for primary molars treated by pulpotomy using diode laser, sodium hypochlorite, or no medication were all 100%. The 2-year radiographic success rates were 90.9%, 100%, and 87.5% for primary molars treated by pulpotomy using diode laser, sodium hypochlorite, or no medication, respectively. However, when the pulpotomy for primary molars was performed by less-experienced residents, a reduced overall success rate from 94% for attending doctors to 58% for residents was found.
Operators and final restorations are confounding factors for determining the success rate of primary molars treated by pulpotomy. Pulpotomy with diode laser, sodium hypochlorite, or no medication are all acceptable treatments of choice for coronally infected primary molars.
背景/目的：牙髓切断术是切除冠部感染牙髓组织，以维持根髓活力和功能的方法。本研究旨在评估使用二极管激光、次氯酸钠或无药物治疗后，经过 24 个月的随访，牙髓切断术治疗乳磨牙的临床和放射学成功率。
通过评估使用二极管激光、次氯酸钠或无药物治疗的牙髓切断术治疗乳磨牙的成功率，根据临床症状和体征以及放射学特征，进行回顾性研究。
本研究共纳入 145 颗乳磨牙。当由经验丰富的儿童牙医治疗并用不锈钢冠修复时，使用二极管激光、次氯酸钠或无药物治疗的牙髓切断术治疗的乳磨牙在临床和放射学成功率方面无显著差异。使用二极管激光、次氯酸钠或无药物治疗的牙髓切断术治疗的乳磨牙 2 年临床成功率均为 100%。使用二极管激光、次氯酸钠或无药物治疗的牙髓切断术治疗的乳磨牙 2 年放射学成功率分别为 90.9%、100%和 87.5%。然而，当由经验较少的住院医师进行乳磨牙牙髓切断术时，发现总成功率从主治医生的 94%降至住院医师的 58%。
操作人员和最终修复是决定牙髓切断术治疗乳磨牙成功率的混杂因素。使用二极管激光、次氯酸钠或无药物治疗的牙髓切断术都是治疗冠部感染乳磨牙的可接受治疗选择。
