Comparative Study
Comparison of chin and jaw movements during gum chewing.
Knowledge 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. ⋯ Chin and jaw movements were correlated during chewing; however, only chewing rate was highly predictable from chin movement data.
