Abstract
REASONS FOR PERFORMING STUDY: Infundibular changes are frequently encountered computed tomographic studies of the equine maxillary cheek teeth but the possible importance of this finding is not known. Infundibular caries is a possible cause for pulpitis and apical infection in some horses. OBJECTIVES: To study the relationship between the 2 pathologies and the frequency of changes. METHODS: The maxillary cheek teeth 108-208, 109-209 and 110-210 of 25 horses were evaluated using computed tomography and both the prevalence of infundibular and apical infection changes as the possible link with apical infection evaluated statistically. RESULTS: The prevalence of infundibular changes was high in both normal and diseased teeth. Both apical infection and the occurrence of infundibular changes were more prevalent in 109-209 and 110-210. In spite of this, the 2 processes could not be linked to one another. No differences were noted between the left and right sides. CONCLUSIONS: A direct relationship between the 2 processes was not established statistically and other underlying causes for the high occurrence of both apical infection and infundibular changes in diseased and normal 108-208, 109-209 and 110-210 are considered.
