本研究旨在探讨咀嚼运动中咀嚼效能与下颌运动的相关性，并对不同咀嚼类型的受试者的咀嚼效能和下颌运动进行评价。选择78名健康受试者，分为两组：双侧和单侧咀嚼。这种分类是通过在咀嚼人造材料期间使用运动描记法来设定的。单侧咀嚼被定义为大多数周期发生在特定的一侧。同样的描记用于定义咀嚼类型被用来评估下颌运动的参数。咀嚼性能分析通过粉碎的人工材料和筛分方法。采用斯皮尔曼相关法以及Mann-Whitney和Student t检验（适当时）在5%显著性水平下进行统计学分析。咀嚼运动中下颌运动参数与咀嚼效能无相关性。双侧咀嚼者表现明显更好（p
The aims of this study were to correlate masticatory performance with mandibular movements during mastication, and to evaluate masticatory performance and mandibular movements of subjects with different types of mastication. Seventy-eight healthy dentate subjects were selected and divided into 2 groups: bilateral and unilateral chewers. This classification was set by using kinesiography during mastication of an artificial material. Unilateral mastication was defined as the majority of the cycles took place at one specific side. The same tracings used to define type of mastication were used to evaluate mandibular movements by means of its parameters. Masticatory performance was analyzed by comminution of the artificial material and a sieving method. Statistical analysis was performed by Spearman's correlation method, and Mann-Whitney and Student's t-test, when appropriate, at 5% significance level. No correlation was found between masticatory performance and parameters of mandibular movement during mastication. Bilateral chewers presented significantly better (p
