Oral and facial pain (orofacial pain) is a common reason for a patient to visit the dentist or physician. Mostly, the diagnostic process will be relatively easy. When pain becomes chronic, diagnostics become obscured due to changes in the nervous system and psychosocial factors, which start to play a more important role.
Irrespective of the complexity of pain, it essentially originates from actual or former tissue damage. This will act as a stimulus, which is processed in the nervous system and will eventually lead to reactions, experiences and behaviour (consequences).So in the pain process, three components are involved: the stimulus, processing and consequences. We therefore introduce the stimulus-processing-consequences (SPC) model as a basis for the assessment of orofacial pain.
In this, diagnostics using pharmacological agents play a major role. These aim predominantly at the stimulus and the processing. Injection of local anesthesia in the temporomandibular joint in patients perceiving pain in the temporomandibular joint area, has a pain relieving effect when compared to placebo injection. Also, a pharmacological test, in which several pharmacological agents are subsequently infused intravenously, seems to be able to differentiate between patients with different pain mechanisms.
The consequences may be judged with the quality of life, which seems to decrease when pain persists. An indiviudal assessment of the quality of life may quickly provide a starting point for further (psychosocial) diagnostic assessment.
By involving different SPC levels simultaneously, a synergystic effect on the efficasy of diagnostics and eventual management of chronic orofacial pain may be accomplished.

The lockdown in March 2020 was difficult for everyone in the Netherlands, but especially so for newcomers: they had 50% less contact than previously. As a consequence, they felt lonelier and their integration into society has almost come to a...
Eén op de vijf medewerkers in een verpleeghuis kampt met depressieve klachten (19%) of burn-out klachten (22%). Met name de medewerkers die voor bewoners met Covid-19 moesten zorgen ervaren vaak depressieve klachten. Dit blijkt uit een onderzoek...
