An Epidemiological Study on Orodental Disorders in 3,791 Working Donkeys in Egypt: Prevalence and Risk Factors

Orodental disorders are common in equidae and can lead to serious clinical complications. This study determines the prevalence rate (PR) of orodental disorders in working donkeys in Egypt and their potential risk factors. During 4 years, 3,791 donkeys were examined in six Egyptian governorates. Full case history and thorough clinical and oral examinations were performed. Radiography and oroendoscopy were undertaken whenever possible. All data were statistically analyzed using Poisson generalized linear models to compare PR among governorates, sex, years, body condition score, and age groups and to determine the potential risk factors. Of 3,791 examined donkeys, 954 donkeys (25.17%) had orodental disorders. The PRs of acquired disorders were 9.81% sharp enamel points, 5.86% buccal ulcers, 4.88% hook, 4.70% overgrown teeth, 4.19% periodontal disease, 3.11% ramp, 2.60% dental caries, 2.37% dental calculus, 2.30% diastema, 2.06% step mouth, 2.00% soft tissue injuries other than buccal ulcers, 1.77% worn tooth, 1.37% loose tooth, 1.29% exaggerated transverse ridge, 1.24% fractured teeth, 0.82% missing teeth, 0.69% wave mouth, 0.50% molar table angle change, and 0.45% wolf tooth overgrowth. The PRs of the congenital disorders were 1.90% displaced teeth, 1.37% deviated teeth, 0.58% retained teeth, 0.16% overbite, 0.16% underbite, 0.11% supernumerary teeth, and 0.11% premolar cap. The risk factors significantly associated (P < .05) with the orodental disorders were age and sex of the animal, geographic location, and year of examination. This study provides a database for future studies on orodental disorders and for designing effective preventive and therapeutic strategies for these disorders in donkeys.
