Peculiarities of chronophysiological rhythms of temperature, electrical and mechanical pain thresholds and two–point discriminative tactile thresholds of oral mucosa were evaluated. Comparative analysis showed a similarity between chronophysiological rhythms of pain perception and tactile sensation from 8 a.m. to 8 p.m. It was established that the extremes of pain and two–point discriminative tactile perception develop from 12 a.m. to 2 p.m., and minimum perception is at 8 a.m. and from 6 p.m. to 8 p.m. Correlations between temperature, electrical and mechanical pain thresholds were revealed, as well as correlations between these types of pain sensations and tactile perception of oral mucosa. These results allow a prediction of individual level of pain sensation during dental treatment.
