Dental disease is a troublesome health concern in alpacas. Specifically, the occurrence of tooth root abscesses has been described in veterinary literature. Nevertheless, no objective prevalence data are available for dental disorders in alpacas.
HYPOTHESIS/OBJECTIVES: To determine the prevalence of dental disorders in alpaca herds in Belgium and the Netherlands. To study the associations between the different dental disorders encountered in alpacas.
A total of 228 alpacas (Vicugna pacos) originating from 25 farms.
This is a cross-sectional study. Dental disorders were diagnosed by dental examination of sedated animals using a dental mirror or a portable rigid oroscope.
At the animal level, 82% (n = 187) had dental disorders of which 74.6, 41.7, and 3.9% were cheek teeth, incisor disorders, and canine disorders, respectively. At the level of the cheek teeth, diastemata (43.1%) were most common, followed by wear abnormalities (WA; 39.6%) and periodontal disease (PD; 33.3%). A significant association was detected between the presence of diastemata and PD (odds ratio [OR], 13.1; 95% confidence interval [CI], 6.6-27.7; P < .001). Pulp exposure was significantly associated with the presence of diastemata (OR, 11.8; 95% CI, 3.8-51.5; P < .001), PD (OR, 8.2; 95% CI, 3.1-25.3; P < .001) and WA (OR, 2.9; 95% CI, 1.2-7.4; P = .002).
Dental disorders are highly prevalent in alpacas in Belgium and the Netherlands. Several dental disorders in alpacas had significant associations. To prevent the development of advanced stages of dental disease, routine dental examinations are advised to allow early detection and prompt treatment.
牙齿疾病是羊驼的一个令人困扰的健康问题。具体来说，兽医文献中已经描述了牙根脓肿的发生。然而，羊驼牙齿疾病的客观流行数据尚不可用。
假设/目的：确定比利时和荷兰羊驼群中牙齿疾病的流行情况。研究在羊驼中遇到的不同牙齿疾病之间的关联。
共 228 只羊驼（Vicugna pacos），来自 25 个农场。
这是一项横断面研究。通过对镇静动物进行牙科检查，使用牙科镜或便携式刚性窥镜来诊断牙齿疾病。
在动物水平上，82%（n = 187）有牙齿疾病，其中 74.6%、41.7%和 3.9%分别为颊齿、切齿疾病和犬齿疾病。在颊齿水平上，牙间隙（43.1%）最为常见，其次是磨损异常（WA；39.6%）和牙周病（PD；33.3%）。牙间隙的存在与 PD 之间存在显著相关性（比值比 [OR]，13.1；95%置信区间 [CI]，6.6-27.7；P < .001）。牙髓暴露与牙间隙的存在显著相关（OR，11.8；95% CI，3.8-51.5；P < .001）、PD（OR，8.2；95% CI，3.1-25.3；P < .001）和 WA（OR，2.9；95% CI，1.2-7.4；P =.002）。
在比利时和荷兰，羊驼的牙齿疾病非常普遍。几种羊驼的牙齿疾病之间存在显著关联。为了防止牙齿疾病发展到晚期，建议进行常规的牙科检查，以便早期发现和及时治疗。
