Clinical and Radiographic Outcomes of PRF, Chitosan, and Blood Clot in Regenerative Endodontics of Molars

During the initial visit, the teeth were anesthetized using inferior alveolar block anesthesia. The endodontic access cavity was then opened. Each canal was irrigated with 2.5% NaOCl and saline. The canals were dried with paper points. Ca(OH)2 was placed in the canals with the objective of achieving an antimicrobial effect. After the application of root canal disinfectant, the opened cavity was sealed with a temporary filling material.The patient has been scheduled for a follow-up appointment within one to four weeks. During the second appointment, local anesthesia was performed using an anesthetic agent that did not contain a vasoconstrictor. The canals were irrigated with 17% EDTA and dried with paper points. Bleeding was induced by instrumentation with a K-type file, at 2 mm past the apical foramen, thus creating a blood clot within the canal. MTA was applied on the scaffold as capping material.

The prepared PRF was placed in the canal space. MTA was applied on the scaffold as capping material.
