摘要再生性牙髓治疗是基于组织工程学的一种治疗手段，目标是实现牙髓-牙本质复合体再生，促使牙髓坏死年轻恒牙的牙根继续发育。方法上与其他组织工程学治疗技术一样依赖种子细胞、支架材料和生长因子这3个要素。该技术提出至今20年来，文献中名称多样，内涵各有异同。本文就再生性牙髓治疗的名称演变、生物学基础、临床考量以及未来科学研究方向进行梳理、分析和阐述，以明了尚未解决的科学问题，引导再生性牙髓治疗在临床上合理开展与规范操作。

abstractsRegenerative endodontic therapy is a tissue engineering based approach of treatment for endodontic disease. Its purpose is to achieve the regeneration of the pulp-dentin complex, thus to promote root development of the immature permanent tooth with necrotic pulp. Like other treatments based on tissue engineering techniques, the success of regenerative pulp therapy depends on such three elements as seed cells, scaffold materials and growth factors. Since its inception 20 years ago, there have been various terminologies in the literature, with similarities and differences in connotation. The present article summarizes and analyzes the term evolution, biological basis, clinical considerations and future scientific research directions of regenerative endodontics, in order to find out the unsolved scientific problems and to promote the development and standardization of this technique in clinical practice.
