Radiotherapy is one of the treatments for cancer, which leads to many oral side effects that affect the quality of life of the patient; among them, trismus is considered.Considering the various therapies to treat this collateral effect of radiotherapy, photobiomodulation (PBM) with low-level laser is a contemporary alternative.In this article, an all-clinical case report is presented in which the patient was given trismus after radiotherapy and PBM with low-level laser. The measurement of the buccal opening was evaluated in each treatment session with a digital caliper, and the pain was evaluated through the visual analog scale (VAS).The efficacy of the PBM protocol on the trismus after radiotherapy was evidenced by the decrease of pain and increase of the buccal opening.The use of PBM with low-level laser is an option for the treatment of trimus after radiotherapy.
