本研究旨在探讨乳牙期儿童咀嚼运动的特点，并与成人进行比较。咀嚼周期的传统参数的均值和方差，即，对23名儿童和25名成年女性的下颌切牙、磨牙和髁突的移动时间、移动范围和三维移动距离进行了分析和比较。儿童的开放时间明显短于成人。儿童和成人之间的显着差异，观察到的横向和垂直偏移的切牙，横向偏移的磨牙，垂直偏移的髁。许多这些测量有较大的主题之间和周期之间的差异，在儿童比成人，这表明儿童的咀嚼运动尚未成熟。本研究结果表明，儿童咀嚼运动不同于成人。
This study was undertaken to characterize jaw motion during mastication in children with primary dentition and to compare jaw motion with that in adults. The means and the variances of the traditional parameters for the chewing cycle, i.e., duration, excursive ranges and 3-D distances of travel at the lower incisor, molars and condyles were analyzed and compared in 23 children and 25 female adults. The duration of opening in children was significantly shorter than that of adults. Significant differences between children and adults were observed in lateral and vertical excursion of the incisor, lateral excursion at the molars, and vertical excursion at the condyles. Many of these measurements had larger between-subject and between-cycle variances in children than adults, suggesting that chewing motion in children has not yet matured. The results of this study indicate that chewing motion in children is different from that of adults.
