Pulp necrosis in immature teeth subsequent to caries has a major impact on long-term tooth retention. The aim of vital pulp therapy is to maintain pulp viability by eliminating bacteria from the dentin-pulp complex and to establish an environment in which apexogenesis can occur. A complicating factor in treating immature teeth is the difficulty predicting the degree of pulpal damage. The ability of the clinician to manage the health of the remaining pulpal tissue during the procedure is paramount. Currently, the best method appears to be the ability to control pulpal hemorrhage by using sodium hypochlorite. Mineral trioxide aggregate (MTA) currently is the optimum material for use in vital pulp therapy. Compared with the traditional material of calcium hydroxide, it has superior long-term sealing ability and stimulates a higher quality and greater amount of reparative dentin. In the medium-term clinical assessment, it has demonstrated a high success rate. Thus, MTA is a good substitute for calcium hydroxide in vital pulp procedures.
龋病导致的年轻恒牙牙髓坏死对牙齿的长期保留有重大影响。活髓治疗的目的是通过消除牙本质 - 牙髓复合体中的细菌来维持牙髓活力，并建立一个能发生牙根继续发育的环境。治疗年轻恒牙的一个复杂因素是难以预测牙髓损伤的程度。在治疗过程中，临床医生管理剩余牙髓组织健康的能力至关重要。目前，最好的方法似乎是使用次氯酸钠控制牙髓出血的能力。矿物三氧化物凝聚体（MTA）目前是活髓治疗中使用的最佳材料。与传统的氢氧化钙材料相比，它具有卓越的长期密封能力，能刺激形成更高质量和更多量的修复性牙本质。在中期临床评估中，它已显示出高成功率。因此，在活髓治疗程序中，MTA是氢氧化钙的良好替代品。
