Perioral somesthetic sensibility: Do the skin of the lower face and the midface exhibit comparable sensitivity?

Novel methods of applying direct chemical and mechanical stimulation to the oral mucosa for traditional behavioral pain assays in conscious rats

“…The baseline mechanical pain threshold observed in the oral mucosa was considerably lower compared with the facial skin, which is consistent with previous reports in humans (Jacobs et al, 2002;Rath and Essick, 1990). This difference in pain threshold is most likely caused by differences in tissue toughness and/or mechanical sensor expression.…”

Age Differences in Orofacial Sensory Thresholds

“…These improvements over previous work point to a more global sensory-perceptual difference between older and younger individuals than was possible with single-modality studies. The observed greater sensitivity of the upper lip compared with the chin site is consistent with previous reports (Rath and Essick, 1990;Jacobs et al, 2002) and offers a measure of task validity. The observed elevation in thresholds of both the somatosensory and gustatory stimuli with increasing age is consistent with reported findings, for taste (Grzegorcyk et al, 1979;Schiffman, 1979;Cowart, 1981;Weiffenbach et al, 1982), smell (Schiffman, 1979;Murphy, 1983;Cain and Stevens, 1989), mechanoreception (Kenshalo, 1979(Kenshalo, , 1986Lautenbacher et al, 2005), and pain (Harkins et al, 1984).…”

Effect of mental arithmetic stress on periodontal sensation in the upper molar and tactile sensation in the cheek

“…The absolute threshold for tactile detection in the upper lip and nasal region ranged from 5 to 9 mg 47 . In this study, the detection threshold of the cheek skin was approximately 11 mg.…”

“…The absolute threshold for tactile detection in the upper lip and nasal region ranged from 5 to 9 mg. 47 In this study, the detection threshold of the cheek skin was approximately 11 mg. When measuring the tactile sensation in the cheek skin using the method of limits, the participants may not respond to the minimum stimulus (manufactured No.…”
