[Discussion on the common issue about regenerative endodontic treatment, apexification or apical barrier].

Regenerative endodontic treatment, apexification or apical barrier can all eliminate the signs and symptoms induced by pulp necrosis with or without apical periodontitis of young permanent teeth, and promote the healing of bone lesions. Although regenerative endodontic treatment may promote the continued development of the root in affected teeth, it is difficult to predict the prognosis as influenced by various factors. And calcification is common after regenerative endodontic treatment. Moreover, the views that apexification may increase the risk of root fracture and that apexification or apical barrier cannot promote the further development of the roots are biased. For some cases, apexification or apical barrier are still good choices. In clinic, when the treatment plan is made, the factors such as the medical condition of the patients, the degree of root development of the affected teeth, the cause and the course of diseases, the amount of residual dental tissues should be fully considered to obtain the best prognosis for the affected teeth.根尖诱导成形术、根尖屏障术及再生性牙髓治疗（RET）均可消除伴或不伴根尖周感染牙髓坏死年轻恒牙的症状、体征，促进骨组织病损愈合。尽管RET可促进患牙牙根继续发育，但影响因素众多，结果难以预期，且术后常出现根管钙化。而根尖诱导成形术可增加根折风险、根尖诱导成形术和根尖屏障术不能促进牙根继续发育的观点存在一定偏颇，对某些病例而言，以上术式仍然是很好的选择。临床制订治疗方案时，应充分考虑患者的全身状况、患牙牙根发育程度、病因、病程、患牙剩余牙体组织量等因素，选择合适的治疗方案，以获得理想的预后。.
