Comparison of a Vegetable-Based Dental Chew to 2 Other Chews for Oral Health Prevention.

Giving dental chews to dogs is part of the passive homecare that helps prevent the formation of plaque and tartar. The objectives of these studies were to assess the effectiveness of a vegetable-based dental chew (VF) to maintain oral health, and to compare it to 2 different reference chews (RC) with a proven effectiveness. The first study was conducted on 45 small dogs (<10 kg) and the second on 60 larger dogs (15-30 kg) who were randomly assigned to 3 different groups. During 30 days, one group received no chew (control) while the second and third group received either one RC (RC1 or RC2) or one VF per day. All dogs had their teeth scaled on Day 0. On Day 30, scores were given for plaque and calculus. Gingival parameters were also assessed. Statistical analysis (analysis of variance and Tukey tests ± Bonferroni's adjustment) were performed to compare groups with α set at .05 for significance.The 3 types of chews were found to be efficacious to reduce plaque and calculus formation and the gingival bleeding compared to control (P < .05). There was no significant difference between RCs and VF in both trials except for the gingival bleeding parameters which showed a greater improvement with VF. Therefore, daily administration of the VF is effective to reduce plaque and calculus formation and gingival bleeding and has a better efficacy on gingival bleeding than the other reference products tested. It can therefore be used with confidence at home for preventative dental care.
