Cross sectional epidemiological study of the severity of buccal ulceration and sharp enamel points in ridden and unridden horses.

The research investigated the effect of human contact in the development of sharp enamel points and buccal ulcerations in horses, finding a higher incidence of these conditions among ridden horses vs unridden ones.

Overview of the Research

• The study commenced from the standpoint of considering the effects of the process of domestication on horses, highlighting changes in dietary compositions and physical activity which have potentially impacted their welfare.
• As part of this research, the scientists focussed on investigating the manifestations of two dental conditions – sharp enamel points (SEP) and buccal ulcerations (BU) in the study sample of horses.
• The key demographic separation made in the population of horses was whether they were ridden or unridden, as a proxy for the degree of human contact, and potentially, stress levels.

Methodology and Findings

• Using logistic regression models, the researchers were able to capture and compare the occurrences and impacts of SEP and BU in the ridden and unridden horse populations.
• The findings showed that both conditions were significantly prevalent among ridden horses (p < 0.001 for SEP and p < 0.01 for BU), suggesting that a degree of human contact could be a contributing factor towards deteriorative dental conditions.
• A further correlation confirmed that the presence of buccal ulceration and sharp enamel points had a positive correlation (ρ = 0.63, p < 0.001), indicating the likelihood that horses suffering from one condition are also disposed to suffering from the other.

Implications and Recommendations

• The findings led the researchers to propose that the level of human contact may indeed have a negative effect on horses’ welfare, particularly in relation to dental health.
• The paper called for further research to gain more insight into the nuances of this impact, beyond ridden and unridden demarcation.
• However, in the meantime, professionals involved in horse care can utilise horse dentistry to alleviate the horses’ discomfort and improve their welfare conditions.
• The writers stress that while dentistry may provide relief, an absolute solution would also involve giving horses regular access to grazed land, aligning closer with their natural instincts, to improve overall welfare conditions.
