对于牙髓感染或坏死且根尖孔未闭合的年轻恒牙,采用再生性牙髓治疗,不仅能使根尖孔闭合,还能使牙根延长,根管壁增厚,从而减少患牙远期根折的风险。动物实验和临床研究都表明,再生性牙髓治疗后形成了新组织。本文就再生性牙髓治疗后新组织形成的研究进展做一综述。 For pulp infection or necrosis of the apical foramen and did not close the young permanent teeth, the use of regenerative endodontic treatment, not only can make the apical foramen closed, but also make the root extension, root canal wall thickening, thereby reducing the long-term teeth Root fold risk. Both animal experiments and clinical studies have shown that new tissue is formed after regenerative pulp therapy. This article reviews the research progress of new tissue formation after regenerative pulp therapy.
