Description
Summary:•To report the use of low power laser in oral lesions in dogs.•The reduction of inflammation and microbial load using conservative methods.•A non-invasive supporting treatment for damaged mucosal and gingival tissues.•The dependence on the patient's behavior avoids anesthetic procedure. Chronic gingivostomatitis in dogs is an inflammatory syndrome of the oral cavity, which treatment and control of concomitant periodontitis allow healing in most of the cases. In the presence of recurrent lesions, invasive methods are necessary to treat lesions and pain. As a conservative adjuvant method, photobiomodulation (PBM) with low power laser is able to promote reduction of tissue pain and tissue inflammation besides increasing vascularization and healing, restoring the normal function of the irradiated organ in a shorter time. In veterinary medicine, there is no standardization of technique for its use in oral tissue for treating gingivostomatitis in dogs. In the present case, a dog was submitted to aPDT (7.2J/point, 3min/point, 180J/cm2) and PBM (1.6J/point, 40s/point, 25J/cm2), using a semiconductor diode laser, with wavelength of 660nm, spot size of ​​0.04cm2 and output power of 40mW. The established protocol proved to be effective as coadjutant treatment for chronic gingivostomatitis, restoring the integrity of dog’s affected mucosa and gingiva.
