Pulp capping should always be considered as the primary treatment of choice for teeth without irreversible pulpitis in lesions approaching dental pulp. The predictability of vital pulp therapy has improved with the introduction of newer bioceramic materials.
The purpose of this randomized controlled trial was to compare the outcomes of mineral trioxide aggregate (MTA) (Angelus, Londrina, Brazil) and a pozzolan-based cement (ENDOCEM-Zr [Maruchi, Wonju, Korea]) as an indirect pulp capping (IPC) material.
IPC was performed in forty patients who were randomly divided into ENDOCEM-Zr and MTA groups. The outcome was assessed using clinical and radiographic tests at different time intervals. The prognostic factors on the outcome of IPC were also evaluated.
The success rate of ENDOCEM-Zr and MTA groups was 94.7% and 89.4%, respectively. The results were not statistically significant. Binary logical regression showed that the age of the patient and the status of the pulp before treatment were deciding variables for the outcome of the study. Therefore, it was concluded from the study that the evaluated pozzolan-based cement could be used as an alternative to MTA because of its faster setting time and lower discoloration potential. In addition, pulp capping should be performed with caution in individuals above 40 years and in teeth with reversible pulpitis.
对于牙髓未发生不可逆性炎症且病变接近牙髓的牙齿，牙髓盖髓术应始终被视为首选的主要治疗方法。随着新型生物陶瓷材料的引入，活髓治疗的可预测性有所提高。
本随机对照试验的目的是比较矿物三氧化物凝聚体（MTA）（巴西隆德里纳的安热卢斯公司）和一种火山灰基水门汀（ENDOCEM-Zr [韩国原州的马鲁奇公司]）作为间接盖髓术（IPC）材料的治疗效果。
对40例患者进行IPC治疗，这些患者被随机分为ENDOCEM-Zr组和MTA组。在不同时间间隔使用临床和影像学检查评估治疗效果。还评估了影响IPC治疗效果的预后因素。
ENDOCEM-Zr组和MTA组的成功率分别为94.7%和89.4%。结果无统计学差异。二元逻辑回归显示，患者年龄和治疗前牙髓状况是决定本研究结果的变量。因此，研究得出结论，所评估的火山灰基水门汀因其凝固时间更快和变色可能性更低，可作为MTA的替代品使用。此外，对于40岁以上个体和患有可逆性牙髓炎的牙齿，应谨慎进行盖髓术。
