The extractions were realized under local anesthesia, with piezotome and pliers. The patients were divided in two groups, the first group of 120 patients which benefited the application of PRF in the post-extraction alveoli, and the second group of 120 patients represented the control group (without application of PRF). A questionnaire was realized after a VAS analog scale and was used to quantify the post-intervention pain intensity in the postoperative four days. The assessment of the post-extraction sites healing period was performed clinically. According to the obtained results, the healing period of the post-extraction sites was shorter in the patients of first group (PRF), compared to the sites of control group patients. No postextractional healing complications occurred in the patients of first group/PRF. The study demonstrated the benefits of PRF insertion in post-intervention healing.
