Eight volunteers participated in an experiment designed to measure gingival and digital vascular responses to suggestions of heat or cold during hypnotic trance. Although verbal and overt motor responses generally agreed with suggestions of heat or cold, vasomotor responses did not. [ABSTRACT FROM AUTHOR]

Longitudinal studies were performed on patients with recurrent attacks of acute necrotizing ulcerative gingivitis (ANUG) during remission. Their psychophysiologic responses to standardized stress procedures (cold-pressor stimulation, breath holding, and immersion of the fifth digit in ice water) were tabulated. The data suggested that a peripheral vasomotor defect in ANUG may be reflected in elevated digital temperatures and general hypotonicity of the digital vasomotor system. [ABSTRACT FROM AUTHOR]
