In the present case, the patient had a previous clinical diagnosis of decompensated type 2 DM, corroborating with Ko et al, 4 in which he found that chronic hyperglycemia worsens odontogenic infections, alters oral vascularization, and increases the time for wound healing.The diagnosis of odontogenic infections with characteristics of NF is essential. Immediate treatments include surgical debridement and broad-spectrum antibiotic therapy, with hyperbaric oxygen therapy and the graft technique, associated with PBM, as an adjuvant therapy to improve surgical results. 5 In this report, grafting was not used because the patient did not want to be operated on due to the risk of loss of the grafted tissue due to her systemic conditions.A review of the literature on PBM in wound healing in DM revealed that the most satisfactory results were observed when an energy density of 3 to 5 J/cm 2 and a wavelength of 632.8 nm was used. 6 Photobiomodulation is a safe technique as long as it is used within the appropriate parameters. It contributes to reducing the healing time, patient discomfort, and improving histological tissue organization. 3,6
