研究目的:

本研究的主要研究目的是与传统的根尖诱导成形术相比,探究再生性牙髓治疗是否能提高年轻恒牙全脱位再植后牙根外吸收的治疗成功率,次要研究目的包括临床症状改善时间,牙根外吸收程度,牙根继续发育比例以及存活率。  

Objectives of Study:

The main research objective of this study is to investigate whether regenerative pulp therapy can improve the success rate of root resorption after complete dislocation and replantation of young permanent teeth compared to traditional root tip induction and shaping surgery. Secondary research objectives include the time for clinical symptom improvement, degree of root resorption, proportion of root development, and survival rate.
