【 摘 要 】

The purpose of this retrospective study was to evaluate the relationship between occlusal and clinical parameters and the need for incisor shortening in horses. It was based on the retrospective analysis of the dental charts of 75 confined horses. Body condition score, shape of incisors, presence of dysmastication, excursion to molar contact (EMC) distance before and after cheek teeth occlusal adjustment were evaluated. History of difficult to riding, dysmastication and digestive problems was also considered. The initial measurement of lateral excursion to molar contact (EMC) revealed incisor occlusal surface abnormalities in 45 (60%) horses and long incisors (EMC>15mm) in five (6.6%) horses. Considering clinical examination and history data the need for reduction of incisor length was significant when EMC exceeded 15mm (P<0.0001) and when based on dental shape, clinical history of dysmastication and/or digestive problems or body condition score was also significant (P<0.05). In confined horses, the decision to shorten and align the incisor teeth should be based on observation and history of dysmastication and digestive problems, body condition score, incisors shape and EMC distance. The need for incisor reduction should be determined before dental intervention and reassessed following cheek teeth oclusal adjustment
