Pathophysiology of acquired dental diseases of the horse

Periodontitis, infundibular necrosis, and periapical infection are dental diseases commonly affecting adult horses. Routine dental examinations and care may help to prevent these diseases. Further investigation of the treatment of horses with these diseases using local antimicrobial therapy, restorative dentistry, and endodontic therapy is needed. An understanding of the pathogenesis of these diseases aids in diagnosis and treatment. Gingival hyperplasia and odontogenic tumors are uncommon but should remain in a list of differential diagnoses when examining a horse with pertinent clinical signs. Recognition of odontogenic tumors as early as possible may facilitate surgery. Examination of the oral cavity of foals beyond the neonatal period should allow identification of brachygnathia and timely treatment when indicated.
