The objective of this study was to investigate the effect of routine dental occlusal equilibration treatment on dressage horse performance. Sixteen horses (11 treated; 5 untreated) ridden by a single rider performed a standardized dressage test twice and were scored by two experienced dressage judges according to recognized movements and rider cues. All horses were sedated and a full-mouth speculum was used to facilitate a complete oral examination. Treated horses had dental equilibration performed using a motorized dental instrument. The horses performed a second test 48-hours after dental equilibration, exactly as the baseline test, with the judges and rider blinded as to treatment group. The total test score as well as the individual movement scores were evaluated for equality of variance and statistical tests were applied to determine the influence of treatment. There was no significant improvement in the test score of horses that had received occlusal equilibration.
本研究的目的是调查常规牙齿咬合平衡治疗对盛装舞步马表现的影响。由一名骑手骑乘的16匹马（11匹接受治疗；5匹未治疗）进行了两次标准化盛装舞步测试，并由两名经验丰富的盛装舞步裁判根据公认的动作和骑手提示进行评分。所有马匹均使用镇静剂，并使用全口开口器以方便进行全面口腔检查。对接受治疗的马匹使用电动牙科器械进行牙齿平衡处理。马匹在牙齿平衡处理48小时后进行第二次测试，与基线测试完全相同，裁判和骑手均对治疗组不知情。评估总测试分数以及各个动作分数的方差齐性，并应用统计测试来确定治疗的影响。接受咬合平衡处理的马匹的测试分数没有显著提高。
