Summary The aim of this study was to compare the salivary cortisol level, pain intensity and psychological factors between patients with chronic and acute oro‐facial pain ( OP ) and pain‐free subjects. Twenty‐seven females with chronic OP (a diagnosis of myofascial pain according to the Research Diagnostic Criteria for Temporomandibular Disorders with at least 6 months duration), 24 females with acute OP (<10 days duration) and 27 pain‐free females participated. Morning saliva was collected from all participants for analyses of the cortisol level. The pain intensity was assessed on a 0–10 numeric rating scale. The participants were evaluated by the Symptom Checklist 90‐revised for levels of depression and somatisation, and the Perceived Stress Scale. The cortisol levels among the three patient groups were similar with no significant group differences. The median (interquartile range) current pain level did not differ between chronic and acute OP and was, respectively, 5 (4) and 5 (3). Patients with chronic OP showed significantly higher scores for depression, somatisation and perceived stress compared with patients with acute OP (Ps < 0·001), but there were no significant differences between acute OP and controls. To conclude, there were no differences in cortisol level between groups, despite significant higher levels of depression, somatisation and perceived stress in patients with chronic OP . This shows that psychological distress has a more important role in chronic than in acute OP . However, the relation between pain, adreno‐cortical activity and psychological distress is complex and warrants further investigation.
