Cognitive-behavioral profiles among different categories of orofacial pain patients: diagnostic and treatment implications.
Psychological homogeneity in temporomandibular disorders (TMD) is not conclusive. The multidimensional pain inventory (MPI) has previously identified 3 cognitive-behavioral profiles in TMD and chronic pain patients. Our aims were to replicate these findings in another cultural setting and relate the profiles to the diagnosis and to the treatment demand and outcome. The MPI was administered to 112 referrals comprising 6 categories of patients diagnosed with TMD or intractable orofacial pain. Dysfunctional profiles (high in pain and distress) were most common in patients with orofacial pain of obscure origin and more common in myofascial pain patients than in patients with other TMD diagnoses. Interpersonally-distressed profiles were found in all categories. Among patients with disk displacement, the 3rd profile (adaptive copers with low pain and distress and high control and activity) was most common in earlier successfully diskectomized patients and least common in those about to undergo invasive interventions. A dysfunctional profile was associated with treatment failure, conservative or surgical, and with the demand for radical therapy. Some support for a cyclical causality between pain and psychological factors was found. It is concluded that the robustness of the MPI as a relevant assessment instrument was further strengthened.
