Oral disorders can negatively influence the health and productive efficiency of livestock. This study was performed to evaluate the prevalence for soft tissue, jawbone and dental disorders of small ruminants in South of Iran and analyze the effect of risk factors including age, sex, species, breed, diet, herd size, herd management and diet on these disorders. Data were analyzed by 95% confidence interval for prevalence index of oral disorders. To evaluate the associations between suggested risk factors and oral disorders, univariate and multivariate logistic regression analyses were used. Based on our results, clinical disorders of tooth, jawbone and soft tissue were observed in 523 (39%), 123 (9.2%) and 81 (6%) subjects, respectively, of 1342 sheep and goats. Several factors including age, sex, herd management and diet were significantly associated with disorders of oral cavity in sheep and goats. The odds of oral diseases increased as the age of animals increased. Moreover, Pakistani goats were more likely than Saanen breed to develop oral disorders. In logistic regression analysis of dental disorder, females had 1.7 times higher risk than males. The odds of traditional herds and roughage diet were 3.5 and 2.5 times more than dairy herds and roughage-concentrate diets in tooth disorders, respectively. Therefore, it is important to inform the herders that choosing the proper breed and maintaining a young flock as well as good management and diet can decrease costs and improve economic efficiency.
