In this cross-sectional study, the gingivitis and the calculus indices of the teeth of N = 41 cats were used to model oral health as a dependent variable using a Poisson regression. The independent variables used were "quadrant", "teeth type", "age", and "diet". Teeth type (p < 0.001) and diet (p < 0.001) were found to be significant, however, age was not (p > 0.05). Interactions were all significant: age x teeth (p < 0.01), age × diet (p < 0.01), teeth × diet (p < 0.001), and teeth × age × diet (p < 0.001). The probability of poor oral health is lower in the incisors of young or adult cats, fed a dry diet in comparison to the cheek teeth of older cats fed a wet diet. Diet has a higher contribution to poor oral health than age. It is argued that cats' oral health may be promoted with an early age hygiene of the cheek teeth and with provision of abrasive dry food.
在这项横断面研究中，以N = 41只猫的牙齿的牙龈炎和牙石指数作为因变量，采用泊松回归模型来模拟口腔健康状况。所使用的自变量为“象限”“牙齿类型”“年龄”和“饮食”。结果发现，牙齿类型（p < 0.001）和饮食（p < 0.001）具有显著性，然而年龄不具有显著性（p > 0.05）。所有交互作用均具有显著性：年龄×牙齿（p < 0.01）、年龄×饮食（p < 0.01）、牙齿×饮食（p < 0.001）以及牙齿×年龄×饮食（p < 0.001）。与喂食湿性食物的老年猫的颊齿相比，喂食干性食物的幼年或成年猫的门齿出现口腔健康不佳的概率较低。饮食对口腔健康不佳的影响比年龄更大。有人认为，通过早期对颊齿进行口腔卫生护理以及提供粗磨的干性食物，可以促进猫的口腔健康。
