Effect of Photobiomodulation on Pain and Healing of the Vertical Releasing Incision After Endodontic Microsurgery
Sponsor: The University of Texas Health Science Center, Houston
Summary
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

Conditions
Interventions
PBM treatment
Immediately after the apical microsurgery, PBM therapy will be performed using a 660 nm diode laser (SiroLaser Advance Plus, Dentsply Sirona Inc, Charlotte, North Carolina, USA), with an 8 mm tip diameter . The laser tip will be placed following the outline of the incision flap in a contact mode . The power output of the laser will be 50 milliwatt (mW) and verified by a Power Meter (PM600 Power/Energy meter, Molectron Detector Inc, Portland, OR, USA). Each site will be irradiated for 25 s with an energy density of 10 J/cm2
PBM sham treatment
Immediately after the apical microsurgery, sham therapy will be performed without activating the laser.
EMS
Patients will be anesthetized. All surgeries will be performed using a surgical microscope. After reflection of a mucoperiosteal flap, osteotomies will be performed to access the root apices and apical lesions. Root apices will be resected at 3 mm, and the pathological tissue curetted out. Next, root-end preparations will be made with ultrasonic tips and filled with calcium silicate-based materials. Methylene blue dye will be used for inspection after root-end resection before the root-end preparation and filling. After cleaning the osseous crypt, the wound margins will be reapproximated with 5-0 single interrupted sutures. A gauze will be placed for 30 minutes for wound compression. Sutures will be removed seven days postoperatively
