Sixteen toy breed dogs completed a parallel, 70-day two-period, cross-over design clinical study to determine the effect of a vegetable dental chew on gingivitis, halitosis, plaque, and calculus accumulations. The dogs were randomly assigned into two groups. During one study period the dogs were fed a non-dental dry diet only and during the second study period were fed the same dry diet supplemented by the daily addition of a vegetable dental chew. Daily administration of the dental chew was shown to reduce halitosis, as well as, significantly reduce gingivitis, plaque and calculus accumulation and therefore may play a significant role in the improvement of canine oral health over the long-term.
16只玩具犬完成了一项平行、为期70天的两阶段交叉设计临床研究，以确定一种蔬菜咀嚼型洁齿产品对牙龈炎、口臭、牙菌斑和牙结石积聚的影响。这些犬被随机分为两组。在一个研究阶段，犬只仅喂食非洁齿干狗粮，在第二个研究阶段，犬只喂食相同的干狗粮，并每天添加一种蔬菜咀嚼型洁齿产品。结果显示，每日使用该咀嚼型洁齿产品可减轻口臭，同时显著减少牙龈炎、牙菌斑和牙结石的积聚，因此长期来看可能对改善犬类口腔健康起到重要作用。
