Influence of Age on the Therapeutic Effects of Photobiomodulation following Canine Dental Prophylaxis

Photobiomodulation has been shown to reduce pain and expedite wound healing in animals. To determine the influence the canine's age has on the therapeutic effect of photobiomodulation after dental prophylaxis a low energy GaAlInP laser with a continuous 650 nm wavelength and 100 mW power output was used. Owners had the option to enroll their canine (n = 24) in the study if they were receiving an anesthetized dental treatment. During the post-operative recovery, each patient received irradiation (10 J/cm2) as a member of one of three randomly assigned treatment groups. One group (n = 7) received four treatment points of irradiation on the gingiva of the right upper and lower dental arcade, one group (n = 8) received four treatment points of irradiation on the gingiva of the left upper and lower dental arcade, and one group (n = 9) received a mock gingiva treatment without irradiation. Inflammation and erythema along the gingival treatment area of each canine was scored 24 hours after treatment by a blinded veterinary evaluator in person or via photograph. The data from this study indicates a trend of higher evaluation scores with increasing age of the canine patient. The data also illustrates lower evaluation scores for the canine patients who received photobiomodulation therapy following dental prophylaxis.
