Both wild and laboratory strains of the musk shrew (Suncus murinus) have a high incidence of periodontitis. The authors completed necropsy examinations in 51 shrews to identify dental lesions including tooth loss, mobility and fractures. Dental lesions were identified in significantly more females than males, and older animals were more likely to have lesions present. Shrews with one or more dental lesions weighed significantly less than those without lesions present. Dietary supplementation with mealworms did not significantly affect the incidence of dental lesions or the body weight of male or female shrews. The authors recommend routine body weight measurement as a simple, noninvasive method of detecting shrews with an increased likelihood of having dental lesions.
无论是野生还是实验室饲养的麝鼩（Suncus murinus）都有很高的牙周炎发病率。作者对 51 只麝鼩进行了尸检检查，以确定包括牙齿缺失、松动和骨折在内的牙齿病变。患有牙齿病变的雌性麝鼩明显多于雄性，而老年动物更有可能出现病变。患有一个或多个牙齿病变的麝鼩体重明显低于没有病变的麝鼩。用黄粉虫进行饮食补充并没有显著影响雄性或雌性麝鼩牙齿病变的发生率或体重。作者建议常规测量体重，作为一种简单、非侵入性的方法，用于检测牙齿病变可能性增加的麝鼩。
