简要总结
This study evaluates the impact of autologous 'leucocyte and platelet rich fibrin' (L-PRF) on the periapical bone healing and further root development of infected immature permanent teeth. In the test group regenerative endodontic procedure (REP) is performed with L-PRF as scaffold, in the control group REP without L-PRF is performed .
详细描述
Regenerative endodontic procedures are biologically based procedures designed to restore function of a damaged and nonfunctioning pulp by stimulation of existing stem and progenitor cells present in the root canal and/or the introduction and stimulation of new stem and dental pulp progenitor cells into the root canal under conditions that are favorable to their differentiation and reestablishment of function. L-PRF has the potential advantage of creating a bioactive construct that stimulates the local environment for differentiation and proliferation of these stem and progenitor cells. We have designed this confirmatory study to test the hypothesis that the use of L-PRF in REP of infected permanent immature teeth will accelerate periapical bone healing and stimulate the root maturation.
