The purpose of this study was to compare the success of pulpotomies in primary molars using a new type of mineral trioxide aggregate (MTA; NeoMTA Plus) with a conventional MTA (ProRoot MTA) as a pulpotomy medicament in primary molars. Eighty primary teeth in 28 patients were divided randomly, with 40 teeth in a control group (ProRoot MTA) and 40 teeth in an experimental group (NeoMTA Plus). A standardized pulpotomy technique was performed for each tooth. Clinical and radiographic follow-up examinations were conducted at three, six, and 12 months. At 12 months, the clinical success for ProRoot MTA was 97.4 percent (38 out of 39) and the radiographic success was 94.9 percent (37 out of 39); for NeoMTA Plus, the clinical success was 100 percent (40 out of 40) and the radiographic success was 97.5 percent (39 out of 40). No significant differences were found between the two groups at all follow-up evaluations. NeoMTA Plus showed a high percent success, similar to that of ProRoot MTA. NeoMTA Plus is a potential pulpotomy medicament for primary teeth.
本研究的目的是比较在乳牙活髓切断术中使用新型三氧化矿物凝聚体（MTA；NeoMTA Plus）与传统MTA（ProRoot MTA）作为乳牙活髓切断术药物的成功率。28例患者的80颗乳牙被随机分组，对照组（ProRoot MTA）40颗牙，试验组（NeoMTA Plus）40颗牙。对每颗牙齿实施标准化的活髓切断术技术。在3个月、6个月和12个月时进行临床和影像学随访检查。12个月时，ProRoot MTA的临床成功率为97.4%（39颗中的38颗），影像学成功率为94.9%（39颗中的37颗）；NeoMTA Plus的临床成功率为100%（40颗中的40颗），影像学成功率为97.5%（40颗中的39颗）。在所有随访评估中，两组之间均未发现显著差异。NeoMTA Plus显示出与ProRoot MTA相似的高成功率。NeoMTA Plus是一种有潜力的乳牙活髓切断术药物。
