Equine dental disease part 1: a long-term study of 400 cases: disorders of incisor, canine and first premolar teeth.

This study analyzed dental disorders in 400 horses. The results showed 44 cases with primary disorders in their incisor teeth, 11 with disorders in their canine or 1st premolar teeth, and the rest with disorders in their cheek teeth. Various disorders were identified, such as traumatic damage, retained deciduous, and abnormalities of wear. Different treatment methods were applied and their effectiveness gauged.

Detailed Analysis of the Research

• The research conducted a comprehensive review of dental disorders in horses. In total, the study covered 400 horses that were referred due to various dental issues. This vast sample size adds credibility to the findings of the study and offers a large data pool for conclusions to be drawn from.
• Out of 400 reviewed horses, it was found that 44 cases suffered from primary disorders in their incisor teeth, while 11 cases had disorders in their canine or 1st premolar teeth. The majority of the cases, approximately 345, had primary disorders of the cheek teeth. This gives a broad overview of the most common dental issues horses face, which can be valuable for vets and horse owners alike.
• The study categorized different types of dental disorders including traumatic damage to the teeth and the bones supporting them, retained deciduous, displaced and supernumerary incisors, and abnormalities in wear. Brachygnathia and many of the wear abnormalities were secondary to the primary disorders of the cheek teeth. Only three cases were recognized with apical infection of incisors.
• In terms of treatment, the study found varying levels of success depending on the specific disorder. For example, most cases of fractured incisors responded well to conservative therapy, while retained deciduous incisors typically required extraction. Most cases with supernumerary and displaced incisors, or brachygnathia, were also treated conservatively, suggesting a more cautious approach can often yield positive results.
• In the relatively small subset of cases involving issues with the canine and 1st premolar teeth, the research found most disorders to be developmental displacements that caused bitting problems (abnormalities of head movement associated with the bit). These cases responded well to extraction of the displaced teeth.
