Impact of the use of plasma rich in growth factors (PRGF) on the quality of life of patients treated with endodontic surgery when a perforation of sinus membrane occurred: A comparative study

Introduction: The aim of this retrospective investigation was to evaluate the postoperative quality of life after endodontic surgery in maxillary molars when a sinus membrane perforation occurred and platelet concentrates were used. Materials and methods: Included patients were treated by microsurgical endodontic treatment in molar and premolar maxillary regions between 2007 and 2010. Patients who fulfilled the inclusion criteria were screened. Data from the quality of life questionnaire were analyzed. The use of plasma rich in growth factors (PRGF) (test group) was compared with a control group when a Schneiderian membrane perforation occurred during endodontic surgery performed with a modern technique in maxillary molars and premolars. Results: A total of 20 patients (12 in the control group and eight in the test group) fulfilled the inclusion criteria. No differences were evaluated at baseline for clinical parameters. Significantly improved patients' quality of life was observed in the test group considering symptoms as swelling, bad breath or taste, and pain. Functional activities were less impaired in the test group and swelling was significantly higher in the control group. In the test group, pain was significantly lower than the control group during the first 6 days after surgery and also, the consumption of painkillers was lower for patients belonging to the test group even if it was not statistically significant. Discussion: In general, a small sinus membrane perforation (less than 6 mm) during endodontic surgery did not cause severe complications. The use of platelet concentrates could be effective in reducing the impact on patients' quality of life, decreasing pain and surgery side effects as well as swelling.
