Somatosensory assessment within the orofacial region may be performed using highly standardised quantitative sensory testing (QST). However, the function of the C tactile (CT) afferent, a nerve fibre linked to the perception of pleasant touch, is usually not evaluated. Furthermore, the perception of unpleasantness is also rarely assessed; a dimension not only limited to a painful experience. Therefore, the primary aim was to apply standardised QST stimuli as well as standardised pleasant stimuli and evaluate their potential capacity for evocation of perceived pain, pleasant and unpleasant sensations in the facial region.
