Summary
# Editorial Summary: Dental Disease in Miniature Horses Miniature horses present a distinct clinical population whose oral health characteristics remain poorly understood compared to standard equine breeds, prompting Tracy and colleagues to conduct comprehensive oral and radiographic examinations of 100 miniature horses and correlate their findings with age, morphometric variables, body condition and sex. Crown elongation, oral mucosal ulceration, diastemata, class 1 malocclusion and hypodontia emerged as the predominant conditions, with age representing a significant risk factor—older individuals showing substantially higher prevalence of dental disease, diastemata and crown elongations. Body condition score and cranial morphology also influenced disease presentation; overweight miniatures demonstrated increased susceptibility to class 1 malocclusion, whilst those with wider heads showed elevated prevalence of both dental disease generally and class 1 malocclusions specifically. These findings underscore the need for early and frequent oral assessment protocols tailored to miniature horse practice, enabling practitioners to intervene during earlier disease stages and potentially attenuate progression of conditions that significantly impact welfare and quality of life. For farriers, veterinarians and other equine professionals managing miniatures, this research supports implementing preventive dental screening from a young age as a cornerstone of health maintenance rather than addressing advanced pathology reactively.

Practical Takeaways
- •Implement early and frequent oral examinations in miniature horses as preventive care, starting when young, to identify and manage dental disease before progression
- •Monitor body condition score and head conformation in miniature horses, as higher BCS and wider head structure correlate with increased malocclusion risk
- •Recognize that age is a significant risk factor for dental disease in miniatures—older horses require more frequent dental examinations and interventions
Key Findings
- •Crown elongation, oral mucosal ulceration, diastemata, class 1 malocclusion and hypodontia were the most common dental diseases in miniature horses
- •Older miniature horses had significantly higher prevalence of dental disease, diastemata and crown elongations
- •Horses with high body condition scores had increased likelihood of class 1 malocclusion
- •Miniature horses with wider heads showed higher prevalence of dental disease and class 1 malocclusions
