A novel SPH method for investigating the role of saliva in swallowing using 4D CT images
TL;DR: The experiments suggest that saliva does not provide a significant lubricative effect on the bolus transit times, but it may serve to reduce residue and therefore improve overall swallowing efficacy and corroborate with existing clinical research that finds groups with hyposalivation do not have significantly different transit times with control groups, but that residue may be increased.
