The purpose of this study is to evaluate the effect of Photobiomodulation (PBM) in postoperative pain after endodontic microsurgery (EMS) in patients from the University of Texas Health Science Center at Houston, School of Dentistry Graduate Endodontic Clinic and to assess the soft tissue healing of the vertical releasing incision (VRI) after PBM
The purpose of the study is to evaluate peri-radicular healing after root-end surgery using Leukocyte and Platelet Rich Fibrin. The study population includes patients diagnosed with persistent periapical pathology and scheduled for Endodontic Microsurgery at the University of Pennsylvania School of Dental Medicine, Department of Endodontics. Patients undergoing routine endodontic microsurgery and who meet the inclusion criteria will be given the opportunity to opt in to receive L-PRF in the osteotomy site to promote bone formation. Healing will be assessed radiographically and clinically at six, twelve, eighteen, and twenty-four months.
The objective of this study is to evaluate the Symani System's safety and effectiveness for microsurgical anastomosis during free tissue transfer surgery and lymphovenous anastomosis surgery. The primary endpoints are: * Effectiveness- Rate of intraoperative anastomosis patency at first attempt. * Safety- Freedom from device-related adverse events. Participants will receive treatment as standard of care and be asked to: * Allow the researchers to access and use their information. * If participants are undergoing a lymphedema procedure, they will be asked to undergo a questionnaire as part of the study. * Participants will be asked to comply with the follow-up visits and complete all study procedures/questionnaires as outlined in the protocol.
