Research Diagnostic Criteria Axis II in screening and as a part of biopsychosocial subtyping of Finnish patients with temporomandibular disorder pain.

AIMS: To assess Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) Axis II variables in an initial psychosocial screening and as a part of biopsychosocial subtyping of Finnish referral patients with TMD pain for adjunct multidisciplinary assessment. METHODS: Consecutive Finnish referral patients with TMD pain (n = 135) participated in this questionnaire-based survey. Psychosocial screening was based on Graded Chronic Pain Scale (GCPS) and culturally adjusted Symptom Checklist 90-revised (SCL-90R) depression scale scores and subtyping on GCPS pain-related interference in accordance with previous treatment tailoring studies. Biopsychosocial subtyping variables included symptoms of depression and somatization, general health, pain-related worry, sleep dysfunction, and coping ability. Subtype comparisons were analyzed with Bonferroni adjusted P values and multivariable logistic regression (SAS 9.3). RESULTS: Based on psychosocial screening, 44% of the patients were psychosocially uncompromised (TMD subtype 1), 33% moderately, and 23% severely compromised (TMD subtypes 2 and 3). Compared to TMD subtype 1, TMD subtype 2 patients reported intermediate scores, and the most vulnerable TMD subtype 3 had the poorest general health, most elevated depression, somatization, worry and sleep dysfunction, and poor coping ability (P < .05). According to multivariable logistic regression, depression and worry levels were significantly higher in TMD subtype 3 compared to TMD subtype 1, whilst patients in TMD subtypes 1 and 2 reported significantly better coping ability compared to TMD subtype 3 (P < .05). CONCLUSION: The Finnish RDC/TMD Axis II was found reliable in initial TMD pain patient screening and with further biopsychosocial assessment identified three main TMD subtypes, two with compromised psychosocial profiles for adjunct multidisciplinary assessment.

Assessment of Pain Drawings and Self-Reported Comorbid Pains as Part of the Biopsychosocial Profiling of Temporomandibular Disorder Pain Patients.

AIMS: To assess drawings of pain sites and self-reported comorbid pains as a part of the biopsychosocial profiling of tertiary care referral patients with temporomandibular disorder (TMD) pain. METHODS: A total of 135 consecutive patients referred to tertiary care for TMD pain participated. Patients drew all the sites where they had pain on whole-body pain drawings. Other assessments included self-reported comorbid pains in the head and body regions, the Finnish Research Diagnostic Criteria for TMD (RDC/TMD_FIN Axis II), and additional biopsychosocial and treatment-related variables. Patients were grouped into pain drawing profiles (localized, regional, and widespread) and the associations between these profiles and the biopsychosocial variables were statistically evaluated using Bonferroni adjusted P values and with logistic regression using SAS 9.3. RESULTS: A total of 21% of the patients reported localized TMD pain, 20% reported regional pain (headaches and neckaches), and the majority, 59%, reported widespread pain (local/regional and multiple bodily pain sites). Patients with widespread pain profiles formed a heterogenous group in which 28.2% reported severe and 30.8% reported moderate pain-related disability. The widespread pain patients reported significantly higher levels of depression and somatization, lower levels of general health, more sleep dysfunction, decreased ability to control pain, and greater health care needs compared to patients with localized pain (P < .05). Patients with regional pain profiles reported moderate scores on psychosocial functioning compared to the patients with localized or widespread pain. CONCLUSION: The majority of tertiary care referral patients with TMD pain reported comorbid pains. Pain drawings were found a useful adjunctive tool for screening and as a part of comprehensive biopsychosocial assessment and treatment planning for patients with TMD pain.

Review of aetiological concepts of temporomandibular pain disorders: towards a biopsychosocial model for integration of physical disorder factors with psychological and psychosocial illness impact factors.

Several studies have reported that musculoskeletal disorders of the stomatognathic system, commonly known as temporomandibular disorders (TMD) resemble musculoskeletal disorders and chronic pain disorders in general. There is also general consensus that combined biomedical and biopsychosocial methods best support the assessment and management of the cardinal features of TMD, i.e., pain and dysfunction or physical (peripheral) and psychosocial (central) factors. This overview of the aetiology of TMD will outline conceptualizations of past models and present the current view that patients with TMD should be assessed according to both the physical disorder and the psychosocial illness impact factors. The conceptual theories outlined in this review include biomedical models related to temporomandibular joints, muscles of mastication and occlusal factors, psychological models and the biopsychosocial models. An integrated and multidimensional approach concerning physical and psychosocial factors in temporomandibular pain and dysfunction is presented as an example of how the biopsychosocial model and information processing theory may apply in the conceptualization and management of TMD for various health care professionals.

An 8-year follow-up study of temporomandibular disorder and psychosomatic symptoms from adolescence to young adulthood.

AIMS: To assess the prevalence of subjective symptoms of pain and/or temporomandibular disorder (TMD) dysfunction and their association with psychosomatic (PS) symptoms in a longitudinal follow-up study of Finnish young adults over an 8-year period. METHODS: One hundred twenty-eight Finnish young adults (60 men and 68 women) were assessed longitudinally at the ages of 15, 18, and 23 years using routine stomatognathic methods and a standardized questionnaire. RESULTS: The prevalence of reported TMD symptoms ranged from 6% to 12% for pain symptoms, from 12% to 28% for dysfunctional symptoms, and from 4% to 7% for a combination of these 2 types of symptoms. The prevalence of PS symptoms, which were constantly present in many of the patients who reported them, ranged from 7% to 11%. A significant correlation (P < .05) was found between TMD pain and PS symptoms at the ages of 15 and 18 years. PS symptoms were not significantly correlated to TMD dysfunction symptoms or to experiencing no symptoms at any age. The majority of subjects in all age groups with both TMD and PS symptoms were female, in a ratio of approximately 2 to 1. CONCLUSION: The prevalence of TMD and PS symptoms was low in adolescence and young adulthood, and there was a significant association, although relatively weak, between PS symptoms and reports of either TMD pain or a combination of TMD pain and dysfunction symptoms.

Symptoms, signs, and clinical diagnoses according to the research diagnostic criteria for temporomandibular disorders among Finnish multiprofessional media personnel.

AIMS: To apply the Finnish version of the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) Axis I to assess the occurrence of symptoms, signs, and specific subgroups of TMD, and to study the associations between the most common diagnoses and categoric demographic characteristics (gender, age group, marital status, type of work). METHODS: All 30- to 55-year-old employees of the Finnish Broadcasting Company with at least 5 years at their current employment received postal questionnaires (n = 1784). Of the 1339 respondents (75%), a randomly selected one fifth were clinically examined according to the RDC/TMD Axis I (n = 241, males 48%). RESULTS: Pain symptoms in the face or jaw regions were perceived by 14.9% and pain with 1 or more jaw movements by 9.1%. Diagnoses by the RDC/TMD criteria were: Group I: myofascial pain in 12.9%, myofascial pain with limited opening in 0.4%; Group II: disc displacement with reduction in the right temporomandibular joint (TMJ) in 9.1% and in the left TMJ in 10.8%; Group III: arthralgia in 0.4% and 0.8%, osteoarthritis in 0% and 0.4%, and osteoarthrosis in 1.2% and 1.2%, respectively, in the right and left TMJs. The most common diagnoses were found more often among women than among men. No TMD diagnosis based on the RDC/TMD was obtained in 73% of the subjects. CONCLUSION: The RDC/TMD appear to be of benefit in diagnosing TMD among these multiprofessional media personnel and thus may be suggested for use among nonpatient populations.

Chronic myofascial pain, disk displacement with reduction and psychosocial factors in Finnish non-patients.

This study aimed to determine chronic groups of myofascial pain and chronic disk displacement with reduction over a 1-year period, and to study the relationship between psychological status and these chronic subgroups of temporomandibular disorders (TMD) in non-patients. A total of 211 subjects (males 47%, mean age 46 years; standard deviation 6) attended examinations in 1999 and 2000 performed according to the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD). Chronic myofascial pain was found in 7% and chronic disk displacement with reduction in 11% of subjects; new diagnoses were made in only 4% and 1% of the subjects, respectively. An increase in the level of somatization by 1 step increased the probability of having chronic myofascial pain by over 3 times (P = 0.006). Myofascial pain and disk displacement with reduction seem to be relatively common and fluctuating in nature in non-patients. As somatization associated significantly with myofascial pain, this should be borne in mind in the management of TMD. The results strengthen the rationale of the biopsychosocial orientation in health care.

Temporomandibular joint related painless symptoms, orofacial pain, neck pain, headache, and psychosocial factors among non-patients.

The aims of this study were to assess the prevalence of temporomandibular joint related (TMJ) painless symptoms, orofacial pain, neck pain, and headache in a Finnish working population and to evaluate the association of the symptoms with psychosocial factors. A self-administered postal questionnaire concerning items on demographic background, employment details, perceived general state of health, medication, psychosocial status, and use of health-care services, was mailed to all employees with at least 5 years at their current job. The questionnaire was completed by 1339 subjects (75%). Frequent (often or continual) TMJ-related painless symptoms were found in 10%, orofacial pain in 7%, neck pain in 39%, and headache in 15% of subjects. Females reported all pain symptoms significantly more often than men (P < 0.001). Frequent pain and TMJ-related symptoms were significantly associated with self-reported stress, depression, and somatization (P < 0.001). Perceived poor general state of health (P < 0.001), health care visits (P < 0.001), overload at work (P < 0.001), life satisfaction (P < 0.05), and work satisfaction (P < 0.05) were also significantly associated with pain symptoms, but the work duty was not (P > 0.05). Our findings are in accordance with earlier studies and confirm the strong relationship between neck pain, headache, orofacial pain. TMJ-related painless symptoms, and psychosocial factors. Furthermore, TMJ-related symptoms and painful conditions seem to be more associated with work-related psychosocial factors than with type of work itself.
