RESUMO
The expected contribution of this study is to have a complete view of the available products used in the prevention of periodontal disease in dogs. The related studies in databases including Web of Science, Science Direct, and Scopus, from 1992 to 2021, were retrieved, and 36 studies were used in the systematic review. Among the continents researched, North America proved to have the most developed research relating to the subject. The active ingredients researched, isolated, or compared to each other, were polyphosphates > phytogenics > chlorhexidine > enzymes > vitamin C > xylitol = adelmidrol = and probiotics. The form of use of active products was chewable > solution via water = via food > biscuits > paste and gels > mucoadhesive. Gingivitis index was the most studied parameter used to assess oral health. According to the evidence recovered in the systematic review was possible to conclude that products with different active agents and forms of use demonstrated positive effects in the prevention of periodontal diseases. The results of this study summarize the most frequently used active ingredients and application forms for cleaning dogs' teeth and provide a roadmap for future research on the maintenance of oral health in dogs.
