Pulpotomy is the most frequent endodontic treatment performed on primary teeth. Different pulpotomy procedures and materials have been studied during the last years and recently interest has been focused on the use of Portland Cement (PC) as an alternative to these materials including Mineral Trioxide Aggregate (MTA), but still few clinical studies have been carried out. The aim of this study was to analyse the clinical and radiographic response to the use of Portland cement (PC) in primary molars pulpotomies through a clinical study in paediatric patients.
Eleven carious primary mandibular molars of children aged 3-9 years old were treated by a conventional pulpotomy technique using PC. The teeth were restored with stainless steel crown. Clinical and radiographic follow-up was performed 6 and 12 months after the treatment.
All the treated molars were clinically and radiographically successful at all the follow-up appointments as no pathological findings were observed in any molar. Reparative dentin formation was observed in 100% of the treated molars.
PC could be considered a reasonable alternative to the use of MTA in pulpotomy treatments in primary molars, although more long-term clinical studies are needed to confirm these results.
牙髓切断术是对乳牙进行的最常见的牙髓治疗。在过去的几年中，已经对不同的牙髓切断术程序和材料进行了研究，最近人们对将波特兰水泥（PC）用作这些材料（包括三氧化矿物聚合体（MTA））的替代物的兴趣越来越浓，但仍有很少的临床研究进行。本研究旨在通过对儿科患者的临床研究，分析使用波特兰水泥（PC）治疗乳磨牙牙髓切断术的临床和放射学反应。
对 3-9 岁儿童的 11 颗下颌乳磨牙进行常规牙髓切断术，使用 PC 进行治疗。牙齿用不锈钢冠修复。在治疗后 6 个月和 12 个月进行临床和放射学随访。
所有接受治疗的磨牙在所有随访中均在临床和放射学上成功，没有观察到任何磨牙出现病理性发现。在 100%的治疗磨牙中观察到修复性牙本质形成。
PC 可被视为在乳磨牙牙髓切断术中替代 MTA 的合理选择，尽管需要更多的长期临床研究来证实这些结果。
