Associations between pain-related temporomandibular disorders and dental anxiety at 46 years of age in the Northern Finland Birth Cohort 1966
Acta Odontologica Scandinavica(2023)
摘要
Objectives The aims were (1) to study the association between dental anxiety (DA) and temporomandibular disorders (TMDs) and whether subgroups formed differ in psychological symptoms and pain sensitivity in the Northern Finland Birth Cohort 1966 and (2) to confirm the factor structure of the Hopkins Symptom Checklist-25 assessing psychological symptoms.Materials and methods Data were acquired using questionnaires and clinical examinations at age 46 years (n = 1889). Dental anxiety was assessed with Modified Dental Anxiety Scale (MDAS). Pain-related TMD (myalgia, arthralgia) were assessed according to modified diagnostic criteria for temporomandibular disorders. Pressure pain threshold and tolerance were measured with an algometer. Explanatory factor analysis revealed three factors, named ‘depression’, ‘anxiety’ and ‘distress’.Results Those with high DA and myalgia and/or arthralgia reported higher depression (mean = 1.52), anxiety (mean = 1.61) and distress (mean = 2.06) scores, and lower pressure pain threshold (mean = 496 kPa) and tolerance (mean = 741 kPa) values than those with only DA (1.22; 1.56; 1.84; 613; 875), TMD (1.21; 1.39; 1.83; 600; 908) or neither (1.12; 1.29; 1.58; 707; 1006), respectively.Conclusions Patients with DA and/or myalgia/arthralgia have similar profiles regarding pain sensitivity and psychological symptoms, the burden being highest among those with DA and a TMD diagnosis.
