Introduction: Resection of the root end during periradicular surgery results in an exposed apical dentin surface bounded by cementum with a root canal at its center. After ultrasonic root-end preparation, a root- end filling material is usually placed to seal the root-end cavity preparation. In order to enhance the complete regeneration of hard tissues after periradicular surgery. A new mix of MTA and Hyaluronan was introduced to fasten the periapical bone formation. Material and Methods: Sealing ability evaluation was done using the fluid filtration method at four evaluation testing periods (24hours, 1week, 1month and 3months) comparing MTA and MTA/Hyaluronic acid mix (MHM) when used as a retrograde filling material. Data was analyzed statistically. Results: No statistical significant difference was found between MTA and MTA/Hyaluronic acid mix regarding sealing ability at the four evaluation testing periods. Conclusion: MTA/Hyaluronic acid mix satisfied the sealing ability requirments to be used as a retrograde filling material in comparison with the golden standard of MTA as a comparative group.
