The objective of this study was to collect preliminary data about tooth resorption (TR) from cats treated at the Odontology Service (September 2016-June 2018), part of a University Veterinary Hospital in Spain, with specific emphasis on TR distribution per tooth. Diagnosis was based on visual/tactile inspection and intraoral dental radiographs. This cross-sectional study was carried out on 59 adult cats (27 females, 32 males). TR occurred in 39/59 cats (66.1%; 95% CI: 54.0%-78.2%). The median number of lesioned teeth per TR-affected animal was 3. A highly significant but weak correlation was found for age and number of TR-affected teeth per individual (Spearman´s correlation ρ = 0.381, P = .003, power = 0.853; N = 59). No TR cases were detected in incisors (0/708, 0%) but TR occurred in canines (21/236, 8.9%; 95% CI: 5.4%-12.4%), premolars (78/590, 13.2%; 95% CI: 10.5%-15.9%), and molars (33/236, 14%; 95% CI: 9.7%-18.3%). A significant age influence on TR was found. The greatest TR occurrence corresponded to 307 (21/59; 35.6%; 95% CI: 23.4%-47.8%) followed by 409 (17/59; 28.8%; 95% CI: 17.2%-40.3%), 407 (16/59; 27.1%; 95% CI: 15.7%-38.4%), and 309 (16/59; 27.1%; 95% CI: 15.7%-38.4%). These teeth would be considered as TR-sentinels in the studied population. These findings are relevant for veterinarians working in dental clinics, where the TR prevalence may be high especially in older cats.
本研究的目的是收集西班牙一家大学兽医医院口腔科（2016年9月至2018年6月）治疗的猫牙齿吸收（TR）的初步数据，特别强调每颗牙齿的TR分布情况。诊断基于视觉/触觉检查和口腔内牙科X光片。这项横断面研究对59只成年猫（27只雌性，32只雄性）进行。59只猫中有39只出现TR（66.1%；95%置信区间：54.0%-78.2%）。每只受TR影响的动物患病变牙齿的中位数为3颗。发现年龄与个体受TR影响的牙齿数量之间存在高度显著但较弱的相关性（斯皮尔曼相关性ρ = 0.381，P = .003，检验效能 = 0.853；N = 59）。在门牙中未检测到TR病例（0/708，0%），但在犬齿（21/236，8.9%；95%置信区间：5.4%-12.4%）、前磨牙（78/590，13.2%；95%置信区间：10.5%-15.9%）和磨牙（33/236，14%；95%置信区间：9.7%-18.3%）中出现TR。发现年龄对TR有显著影响。TR发生率最高的是307号牙齿（21/59；35.6%；95%置信区间：23.4%-47.8%），其次是409号牙齿（17/59；28.8%；95%置信区间：17.2%-40.3%）、407号牙齿（16/59；27.1%；95%置信区间：15.7%-38.4%）和309号牙齿（16/59；27.1%；95%置信区间：15.7%-38.4%）。在研究群体中，这些牙齿将被视为TR的哨兵。这些发现对在牙科诊所工作的兽医具有重要意义，在这些诊所中TR的患病率可能很高，尤其是在老年猫中。
