Ozone Therapy in the Prevention of Dental Plaque Formation in Dogs.

This study aims to assess ozonized mineral oil ointment application as an antiplaque therapy for dogs. Domestic healthy dogs received dental scaling and polishing under general anesthesia. Under standard feeding and homecare during 7 days, 20 dogs were randomly placed into 2 different groups for dental treatment. The control group (CG) was given a single placebo application and the ozone group (O3G) received daily ozonized ointment application. The average age (CG = 4.4; O3G = 5.7 years old), body weight (CG = 15.7; O3G = 15.3 kg) and the gingivitis index obtained on the first day (D0) allowed initial homogeneity between the groups. The dental plaque index, including clinical and computerized analysis on the seventh day, was obtained from the buccal aspect of specific dental locations. Both analyses revealed significant statistical association between daily application of ozone and antiplaque effect. There was no evidence of toxicity during the study. These results suggest that ozone therapy may be an efficient adjuvant to conventional periodontal treatment in decreasing initial dental plaque formation.

Antimicrobial photodynamic therapy (aPDT) and photobiomodulation (PBM - 660nm) in a dog with chronic gingivostomatitis.

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.
