To compare clinical and radiographic outcomes of pulpotomy treatment using calcium-enriched mixture (CEM) cement and mineral trioxide aggregate (MTA) in carious-exposed vital immature permanent first molars.
Fifty-one immature molars with clinical carious exposure with symptomatic/asymptomatic pulpitis met the inclusion criteria and randomly assigned to one of the treatment groups (CEM [26 teeth; 59 roots], MTA [25 teeth; 59 roots]). After performing pulpotomy and covering the radicular pulps with the biomaterials, all teeth were permanently restored. Blinded clinical and radiographic evaluations were performed at 6 and 12 months after operation for signs of success or failure. Radiographs were evaluated for complete/partial apical closure. The data were analysed using chi-square test and generalized estimating equation (GEE) model.
There was no significant difference at the baseline between the two experimental groups. All available cases (49 teeth) showed pulp survival and signs of continuous root development after 12 months. Overall, complete apical closure (apexogenesis) occurred in 76.8% and 73.8% of radiographically interpreted roots in CEM cement and MTA groups, respectively. There was no statistical difference in terms of radiographic outcomes between two groups.
Calcium-enriched mixture cement and MTA showed similar performance in pulpotomy of immature caries-exposed permanent molars.
比较使用富钙混合（CEM）水泥和三氧化矿物聚合体（MTA）进行活髓切断术治疗龋暴露的有症状/无症状牙髓炎恒磨牙的临床和影像学结果。
符合纳入标准的 51 颗临床有龋暴露、有症状/无症状牙髓炎的未成熟磨牙随机分配到治疗组之一（CEM[26 颗牙；59 个根]，MTA[25 颗牙；59 个根]）。在进行活髓切断术并用生物材料覆盖根髓后，所有牙齿均行永久性修复。术后 6 个月和 12 个月进行盲法临床和影像学评估，以判断成功或失败的迹象。用 X 线片评估完全/部分根尖闭合。使用卡方检验和广义估计方程（GEE）模型分析数据。
两组在基线时无显著差异。所有可随访病例（49 颗牙）在 12 个月后均显示牙髓存活和持续根尖发育的迹象。总体而言，76.8%和 73.8%的 CEM 水泥和 MTA 组的 X 线片解释根出现完全根尖闭合（根尖形成）。两组的影像学结果无统计学差异。
在龋暴露的未成熟恒牙活髓切断术中，富钙混合水泥和 MTA 表现出相似的效果。
