问题陈述咀嚼的知识是基于在非常规环境下使用下颌跟踪设备的研究。动物行为学家认为，这些数据可能并不能反映日常的咀嚼功能。如果下颌运动可以无创跟踪，那么下颌跟踪设备和非常规设置改变咀嚼的假设可以被调查。目的本研究定量评估嚼口香糖任务中下巴和下颌运动之间的关系。材料与方法对50名受试者在x、y和z轴上的咀嚼下巴和下颌运动进行了15秒的跟踪，结果得出每个受试者大约有15个咀嚼周期。对于每个咀嚼周期，计算每个轴上的位移、速度和加速度极值的大小和时间，以获取颌骨和下巴的运动数据。每15秒试验计算极值平均值。分别用线性回归和相关分析比较代表下巴和下巴运动的均值。结果两组平均极值均显著相关（r范围0.30 ~ 0.99;P < 0.05）。加速度极值的幅度相关性大于时间相关性。相反，位移极值的幅度相关性小于时间相关性。咀嚼速度的相关性最高。结论咀嚼过程中颏部运动与颏部运动相关；然而，只有咀嚼速度可以从下巴运动数据中高度预测。[J] .中华口腔医学杂志，1999;31(1):1 - 7。
Statement of problemKnowledge of mastication is based on studies that use jaw tracking equipment in nonroutine settings. Ethologists would argue that such data probably does not reflect routine masticatory function. If jaw movements could be tracked noninvasively, then the hypothesis that jaw tracking equipment and nonroutine settings alter mastication could be investigated.PurposeThis study quantitatively evaluated the relationship between chin and jaw movements during a gum-chewing task.Material and methodsMasticatory chin and jaw movements of 50 subjects were tracked in the x-, y-, and z-axes for 15 seconds, which resulted in approximately 15 chewing cycles obtained per subject. For each chewing cycle, magnitude and timing of displacement, velocity, and acceleration extrema in each axis were computed for both jaw and chin movement data. Extrema means were calculated for each 15-second trial. The respective means representing chin versus jaw movements were compared with linear regression and correlation analyses.ResultsAll mean extrema were significantly correlated (r range 0.30-0.99; P <.05). Magnitude correlations were larger than timing correlations for acceleration extrema. In contrast, magnitude correlations were smaller than timing correlations for displacement extrema. The highest correlation occurred for chewing rate.ConclusionsChin and jaw movements were correlated during chewing; however, only chewing rate was highly predictable from chin movement data.
