This study evaluated the effectiveness of a newly developed dental hygiene chew for dogs, with and without a natural antimicrobial additive, compared with a reference diet. Efficacy was determined by measuring the severity of gingivitis and the accumulation of dental plaque and calculus in dogs after 4-weeks of being fed the different dietary regimens. Dogs fed a single daily dental chew had significantly less gingivitis (P = 0. 02), plaque (P = 0. 0004), and calculus (P = 0.0001) compared with dogs in the control group that were fed an identical diet but received no chews. The inclusion of the antimicrobial agent did not improve the efficacy of the product. The dental hygiene chews tested in this study have potential to help reduce the incidence of periodontal disease in dogs.
本研究评估了一种新开发的犬用口腔卫生咀嚼物的有效性，该咀嚼物添加或未添加天然抗菌添加剂，并与参考饮食进行比较。通过测量在不同饮食方案喂养4周后犬只的牙龈炎严重程度、牙菌斑和牙结石的堆积情况来确定疗效。与喂食相同饮食但未给予咀嚼物的对照组犬只相比，每天喂食一片口腔咀嚼物的犬只牙龈炎（P = 0.02）、牙菌斑（P = 0.0004）和牙结石（P = 0.0001）明显更少。添加抗菌剂并未提高该产品的疗效。本研究中测试的口腔卫生咀嚼物有潜力帮助降低犬只牙周病的发病率。
