The primary fibromyalgia syndrome (Weichteilrheumatismus) shows a circadian rhythm of the symptoms and, moreover, a seasonality of pain severeness. Although the pathophysiologic mechanisms are unknown, the circadian variations are well documented in the literature; the seasonality of pain is sometimes clinically reported. In a study on "healthy" workers, the seasonality of this disease is reported.
A sample of 6718 healthy persons were asked, during an examination in connection with getting a job, whether they had noticed sounds emanating from their temporomandibular joints. A total of 20.1% of the job applicants reported hearing joint sounds. Crepitation or clicking was found in more than 12.2% of the sample on palpation. Auscultatory examination revealed sounds in almost 72.5% of the individuals. When examined with a phonocardiograph, 84% of a randomly selected subgroup demonstrated joint sounds. Considering the frequency with which this symptom occurred in healthy individuals, caution must be exercised in interpreting joint sounds as definite proof of arthropathy.

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 sensibility). By contrast, the reparative processes in the elderly are dominated by delayed reaction type patterns, while in younger persons early reaction type patterns are prevailing.

Cold and changing (warm/cold) footbaths in a curative dosage, used in physiotherapy, at first have the effect of constantly elevating the temperature of the oral and oropharyngeal mucosa. With longer duration and overdosage of the cold irrigation, a steep decrease of the mucosa temperature ensues. The extent of this reaction is determined by circadian variations. The importance of the elevation of the temperature of the mucosa is discussed with reference to resistance against infections from the common cold.

The course of swelling after maxillo-facial surgery was investigated by measuring the distance from the tragus to the pogonium. The post-surgical swelling does not diminish continuously, but decreases in a circaseptan periodic mode. The reactive periodicity is preferentially induced not by the injury, but by the surgical treatment. Identical surgical treatment induces a lower level of swelling under local anaesthesia. In contrast to 'biological' remedies, 'chemical' antiphlogistic agents, derived from antirheumatic drugs, reduce the extension of swelling, but they also flatten out the increase of swelling around day 7 after surgery.
