After the endodontic treatment, PBM therapy will be performed using a 660 nm diode laser (SiroLaser Advance Plus, Dentsply Sirona Inc, Charlotte, NC, USA), with an 8mm tip diameter.The laser tip will be placed on the following external surfaces in a contact mode: mesiobuccal, distobuccal, mesiolingual and distolingual . The power output of the laser will be 50mW and will be verified by 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 .
For the PBM sham similar procedure as PBM therapy will be performed without activating the laser.
