The objective of this double-blind, randomized controlled clinical study will be to evaluate the effect f PBM on pain after endodontic instrumentation in the single-session treatment of upper molars and premolars. The sample will consist of 58 participants treated endodontically in a single session and randomly allocated to the PBM Group with conventional treatment with photobiomodulation and the Control Group with conventional treatment with simulation of PBM. The primary variable of the study will be the evaluation of spontaneous pain immediately before treatment, and the participant will be reassessed for postoperative pain 24 hours after instrumentation using the visual analog scale (VAS). As secondary variables, pain prevalence, pain at 4h, 8h, and 12h after the procedure, palpation pain (vestibular and lingual), and percussion pain (vertical and horizontal) will be assessed 24 hours after the procedure, as well as the number of necessary analgesics (paracetamol) and the impact of oral health on quality of life evaluated by the OHIP 14 instrument.
