In 136 healthy men, circadian variations in pain threshold have been observed in healthy front teeth, the pain being elicited by a cold stimulus, alterations in threshold then being inferred from changes in the minimum cold application time. The pain threshold is maximal in the early afternoon and at a minimum in the early morning. In previous experiments(More)
The phantom phenomena affecting the extremities also seem to appear after dental extractions. Non-painful perceptions are more frequently observed than painful ones, and young people are more often affected that the elderly. The theories that postulate a central genesis would appear to be more likely than the explanation involving peripheral stimulation.
The sensibility of the epicritic (= tactile) and protopathic (= nociceptive) functions of the teeth decreases with advancing age. This has been demonstrated by simultaneously evaluating the minimum threshold shock duration after low-temperature stimuli (thermal threshold of pain) and the number of errors in wire thickness comparison tests (tactile(More)
The frequencies of 5706 demands for analgetic drugs after dental operations have been recorded. The highest consumption of analgetics is observed around postoperative day 7. On days 2 and 3, the circadian course of the frequencies peaks in the early morning (around 06.00). On days 6 and 7 the frequencies of analgetic administrations increase during the(More)
In accordance with clinical experience, the duration of the action of a local anaesthetic agent used in dental surgery changes depending on the time of day. A statistically significant circadian rhythm in the duration of a local anaesthesia produced by mepivacaine, was found in teeth. The longest duration was ascertained at approximately 15.00 (3 p.m.), the(More)

A maximum of the pain sensibility of the teeth is found during the night. Simultaneous observations of epicritic and nociceptive functions reveal an opposite circadian cycle. During the day-time an analgesic agent effects in the teeth a quicker and longer elevation of the pain threshold than in the night-hours. During the day a placebo results in a greater(More)
Placebo doses can influence the pain threshold of healthy teeth according to the label. Systematic longitudinal researches over the day with measuring the utilization time of cold stimulus on healthy front teeth demonstrate that the placebo effect is subject to significant circadian variations. During daytime a pseudo-analgesic causes a stronger and steeper(More)
At different times of the day, the effect of an analgesic was systematically tested on healthy teeth by using a cold stimulus. The measure of the analgetic effect was the alteration of pain threshold measured by means of the minimum cold application time. In addition to the already known spontaneous variations in pain tolerance at the various times of the(More)
