Adjournment in Community HIV Prevention: Exploring Transitions in Community-Academic Partnerships.

Barbershop-based interventions have been increasingly implemented as a means to support culturally relevant and community-accessible health promotion and disease prevention efforts. Specifically, in neighborhoods of Brooklyn, New York, with high HIV seroprevalence rates, barbers have volunteered to support an initiative to help reduce sexual risk behavior. After implementing the Barbershop Talk With Brothers program for 5 years, we explored how program participation has affected barbers' HIV prevention and counseling skills to promote their clients' health, and assessed their views of next stages of the community-academic partnership, once the specific project ended. Through employing rigorous qualitative research methods with personnel at participating barbershops, key results include that although barbers self-identify as community leaders and even as health educators, they want ongoing support in educating customers about other topics like nutrition and physical activity, including upstream social determinants of health, such as housing and employment. They are also concerned regarding how best to support continuity of efforts and maintenance of partnerships between projects. These findings provide insight toward adjourning community-based participatory research projects, which can inform other academic researchers, organizations, and businesses that partner with community members.

UNITED STATES DENTAL PROFESSIONALS' PERCEPTIONS OF DENTAL ANXIETY AND NEED FOR SEDATION IN PATIENTS WITH MENTAL ILLNESS.

Dental fear is a barrier to receiving dental care, particularly for those patients who also suffer from mental illnesses. The current study examined United States dental professionals' perceptions of dental fear experienced by patients with mental illness, and frequency of sedation of patients with and without mental illness. Dentists and dental staff members (n = 187) completed a survey about their experiences in treating patients with mental illness. More participants agreed (79.8%) than disagreed (20.2%) that patients with mental illness have more anxiety regarding dental treatment (p < .001) than dental patients without mental illness. Further, significantly more participants reported mentally ill patients' anxiety is "possibly" or "definitely" a barrier to both receiving (96.8%; p < .001) and providing (76.9%; p < .01) dental treatment. Despite reporting more fear in these patients, there were no significant differences in frequency of sedation procedures between those with and without mental illness, regardless of type of sedation (p's > .05). This lack of difference in sedation for mentally ill patients suggests hesitancy on the part of dental providers to sedate patients with mental illness and highlights a lack of clinical guidelines for this population in the US. Suggestions are given for the assessment and clinical management of patients with mental illness.

Narrow band (light) imaging of oral mucosa in routine dental patients. Part I: Assessment of value in detection of mucosal changes.

The purpose of this investigation was to determine the value of adding narrow band (light) imaging (NBI) to the standard oral soft tissue examination process used to detect mucosal change. A total of 620 dental patients who came to the clinic for regular dental evaluation or for treatment of acute dental problems were given a standard oral soft tissue examination by dental students under faculty supervision. The results of the white light examination were recorded after the tissues were examined with NBI, at which point areas with a loss of fluorescence (LOF) were recorded. The nature of the tissue change was classified clinically as normal variation, inflammatory, traumatic, dysplastic, or other, and patients were categorized depending on their clinical findings: normal, need follow-up visit, or immediate biopsy. Risk factors related to oral dysplasia also were recorded. The addition of NBI added between one and two minutes to the examination process. Of the 620 examinations, an area with an LOF suggestive of pathology was detected in 69 subjects (11.1%). After a second immediate evaluation, 28 of the 69 subjects were scheduled for follow-up or biopsy. None of the lesions discovered in these 28 subjects had been detected using standard (white light) examination. Adding NBI to the routine clinical examination resulted in detection of changes not seen with white light examination in 11.1% of patients; of these, a small but important number were found to have otherwise undetected persistent changes representing inflammatory lesions or potentially dangerous oral dysplasia. Adding NBI as an adjunctive diagnostic procedure improved the quality and outcome of the examination process.

Neonatal quinpirole treatment enhances locomotor activation and dopamine release in the nucleus accumbens core in response to amphetamine treatment in adulthood.

Neonatal quinpirole treatment to rats produces long-term increases in D(2) receptor sensitivity that persists throughout the animal's lifetime, a phenomenon referred to as D(2) priming. Male and female Sprague-dawley rats were administered quinpirole (1 mg kg(-1)) or saline from postnatal days (P)1-11. At P60, all animals were given an injection of quinpirole (100 microg kg(-1)), and results showed that rats neonatally treated with quinpirole demonstrated enhanced yawning in response to quinprole, verifying D(2) receptor priming because yawning is a D(2) receptor mediated event. Beginning 1-3 days later, locomotor sensitization was tested through administration of d-amphetamine (1 mg kg(-1)) or saline every other day over 14 days, and horizontal activity and turning behavior were analyzed. Findings indicated that D(2)-priming enhanced horizontal activity in response to amphetamine in females compared to males at Days 1 and 4 of locomotor sensitization testing, and D(2)-priming enhanced turning in response to amphetamine. Seven to ten days after sensitization was complete, microdialysis of the NAcc core was performed using a cumulative dosing regimen of amphetamine (0.1-3.0 mg kg(-1)). D(2)-primed rats administered amphetamine demonstrated a 500% increase in accumbal DA overflow compared to control rats administered amphetamine. Additionally, amphetamine produced a significant increase in NE overflow compared to controls, but this was unaffected by D(2) priming. These results indicate that D(2) receptor priming as is produced by neonatal quinpirole treatment robustly enhances behavioral activation and accumbal DA overflow in response to amphetamine, which may underlie increases in psychostimulant use and abuse within the psychotic population where increased D(2) receptor sensitivity is a hallmark.

The Research Diagnostic Criteria For Temporomandibular Disorders. II: reliability of Axis I diagnoses and selected clinical measures.

AIMS: The primary aim was to determine new estimates for the measurement reliability of the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) Axis I diagnostic algorithms. A second aim was to present data on the reliability of key clinical measures of the diagnostic algorithms. METHODS: Kappa (k), computed by generalized estimate equation procedures, was selected as the primary estimate of interexaminer reliability. Intersite reliability of six examiners from three study sites was assessed annually over the 5-year period of the RDC/TMD Validation Project. Intrasite reliability was monitored throughout the validation study by comparing RDC/TMD data collections performed on the same day by the test examiner and a criterion examiner. RESULTS: Intersite calibrations included a total of 180 subjects. Intersite reliability of RDC/TMD diagnoses was excellent (k > 0.75) when myofascial pain diagnoses (Ia or Ib) were grouped. Good reliability was observed for discrete myofascial pain diagnoses Ia (k = 0.62) and Ib (k = 0.58), for disc displacement with reduction (k = 0.63), disc displacement without reduction with limited opening (k = 0.62), arthralgia (k = 0.55), and when joint pain (IIIa or IIIb) was grouped (k = 0.59). Reliability of less frequently observed diagnoses such as disc displacements without reduction without limited opening, and osteoarthrosis (IIIb, IIIc), was poor to marginally fair (k = 0.31-0.43). Intrasite monitoring results (n = 705) approximated intersite reliability estimates. The greatest difference in paired estimates was 0.18 (IIc). CONCLUSION: Reliability of the RDC/TMD protocol was good to excellent for myofascial pain, arthralgia, disc displacement with reduction, and disc displacement without reduction with limited opening. Reliability was poor to marginally fair for disc displacement without reduction without limited opening and osteoarthrosis.

The Research Diagnostic Criteria for Temporomandibular Disorders. III: validity of Axis I diagnoses.

AIMS: To estimate the criterion validity of the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) Axis I TMD diagnoses. METHODS: A combined total of 614 TMD community and clinic cases and 91 controls were examined at three study sites. RDC/TMD Axis I diagnoses were algorithmically derived from an examination performed by calibrated dental hygienists. Reference standards ("gold standards") were established by means of consensus diagnoses rendered by two TMD experts using all available clinical data, including imaging findings. Validity of the RDC/TMD Axis I TMD diagnoses was estimated relative to the reference-standard diagnoses (gold standard diagnoses). Target sensitivity and specificity were set a priori at greater than or equal to 0.70 and greater than or equal to 0.95, respectively. RESULTS: Target sensitivity and specificity were not observed for any of the eight RDC/TMD diagnoses. The highest validity was achieved for Group Ia myofascial pain (sensitivity 0.65, specificity 0.92) and Group Ib myofascial pain with limited opening (sensitivity 0.79, specificity 0.92). Target sensitivity and specificity were observed only when both Group I diagnoses were combined (0.87 and 0.98, respectively). For Group II (disc displacements) and Group III (arthralgia, arthritis, arthrosis) diagnoses, all estimates for sensitivity were below target (0.03 to 0.53), and specificity ranged from below to on target (0.86 to 0.99). CONCLUSION: The RDC/TMD Axis I TMD diagnoses did not reach the targets set at sensitivity of > or = 0.70 and specificity of > or = 0.95. Target validity was obtained only for myofascial pain without differentiation between normal and limited opening. Revision of the current Axis I TMD diagnostic algorithms is warranted to improve their validity.

Generalized joint hypermobility (GJH) may be a risk factor for temporomandibular disorders (TMD).

PURPOSE/QUESTION: The objective of this study was to determine whether generalized joint hypermobility is a risk factor for temporomandibular disorders as defined by the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD). SOURCE OF FUNDING: This study was supported by the Public Health Research Association, Saxony, Germany. TYPE OF STUDY/DESIGN: Population-based cross-sectional cohort study LEVEL OF EVIDENCE: Level 2: Limited-quality, patent-oriented evidence. STRENGTH OF RECOMMENDATION GRADE: Not applicable.

Daily pain coping among patients with chronic temporomandibular disorder pain: an electronic diary study.

AIMS: To describe patients' daily coping with the pain of chronic temporomandibular disorders (TMD), the conservative treatment received, and the self-care strategies used, and to examine the relationships between these strategies and daily pain intensity, activity interference, and jaw use limitations. METHODS: TMD clinic patients (n = 137, 88% women) completed electronic diary measures of pain, interference, jaw use limitations, and use of 20 strategies 3 times daily for 2 weeks. RESULTS: Reliability and validity were demonstrated for 4 scales of related coping items: cognitive coping, relaxation, activity reduction, and emotional support. Average scores were higher on the relaxation and activity reduction scales than on the cognitive coping and emotional support scales. Among the coping items not included in the scales, "did something to try to reduce pain" (direct action) was endorsed most frequently (reported in a median of 74% of interviews). Heat, cold, and seeking spiritual support were used least (< or = 5%). At times of increased pain, patients were more likely to use almost all types of strategies. Pain intensity was associated strongly with concurrent activity interference and jaw use limitations. When the design controlled for pain intensity, activity reduction and seeking emotional support were associated positively within-subjects with interference and jaw use limitations. CONCLUSION: TMD clinic patients use a variety of treatment, self-care, and coping strategies to contend with daily pain. Inquiring about a broad range of strategies might help clinicians better understand how individual patients approach pain management. Research is needed to examine whether decreasing activity reduction and emotional support coping results in improved outcomes.

The efficacy of traditional, low-cost and nonsplint therapies for temporomandibular disorder: a randomized controlled trial.

BACKGROUND: Treatment recommendations for patients with painful temporomandibular disorders (TMDs) range from conservative treatments such as physiotherapy to aggressive and irreversible treatments such as restorative reconstruction and joint surgery. METHODS: The authors randomized 200 subjects diagnosed with TMD into three groups: usual conservative, dentist-prescribed self-care treatment without any intraoral splint appliance (UT); UT plus a conventional flat-plane hard acrylic splint (HS); and UT plus a soft vinyl (a low-cost athletic mouth guard) splint (SS). Subjects completed questionnaires and clinical examinations at three, six and 12 months. RESULTS: The authors observed no significant differences among the groups in TMD-related pain levels or other common signs and symptoms of TMD at baseline (BL) or at any follow-up. The changes from BL were comparable for all three groups. The authors did not note any significant differences at any follow-up for compliance with study protocols or for occurrences of adverse effects from either splint type. For HS versus SS, there were significant differences in rates of splint use, but these differences were not accompanied by differences in either self-reported symptoms or in clinical findings. CONCLUSIONS: All patients improved over time, and traditional splint therapy offered no benefit over the SS splint therapy. Neither splint therapy provided a greater benefit than did self-care treatment without splint therapy. CLINICAL IMPLICATIONS: These findings suggest that clinicians who treat patients with TMD should consider prescribing low-cost nonsplint self-care therapy for most patients.

Switch from excitatory to inhibitory actions of ethanol on dopamine levels after chronic exposure: Role of kappa opioid receptors.

Acute ethanol exposure is known to stimulate the dopamine system; however, chronic exposure has been shown to downregulate the dopamine system. In rodents, chronic intermittent exposure (CIE) to ethanol also increases negative affect during withdrawal, such as, increases in anxiety- and depressive-like behavior. Moreover, CIE exposure results in increased ethanol drinking and preference during withdrawal. Previous literature documents reductions in CIE-induced anxiety-, depressive-like behaviors and ethanol intake in response to kappa opioid receptor (KOR) blockade. KORs are located on presynaptic dopamine terminals in the nucleus accumbens (NAc) and inhibit release, an effect which has been linked to negative affective behaviors. Previous reports show an upregulation in KOR function following extended CIE exposure; however it is not clear whether there is a direct link between KOR upregulation and dopamine downregulation during withdrawal from CIE. This study aimed to examine the effects of KOR modulation on dopamine responses to ethanol of behaving mice exposed to air or ethanol vapor in a repeated intermittent pattern. First, we showed that KORs have a greater response to an agonist after moderate CIE compared to air exposed mice using ex vivo fast scan cyclic voltammetry. Second, using in vivo microdialysis, we showed that, in contrast to the expected increase in extracellular levels of dopamine following an acute ethanol challenge in air exposed mice, CIE exposed mice exhibited a robust decrease in dopamine levels. Third, we showed that blockade of KORs reversed the aberrant inhibitory dopamine response to ethanol in CIE exposed mice while not affecting the air exposed mice demonstrating that inhibition of KORs "rescued" dopamine responses in CIE exposed mice. Taken together, these findings indicate that augmentation of dynorphin/KOR system activity drives the reduction in stimulated (electrical and ethanol) dopamine release in the NAc. Thus, blockade of KORs is a promising avenue for developing pharmacotherapies for alcoholism.

Cyclic effects on experimental pain response in women with temporomandibular disorders.

AIMS: Since cyclic effects on experimental pain response in women with temporomandibular disorders (TMD) have not been adequately studied, the aim of this study was to assess variations in experimental pain response at 4 phases of the menstrual cycle. METHODS: Eighteen normally cycling women with TMD, 25 women with TMD and taking oral contraceptives (OC), 25 normally cycling pain-free controls, and 26 pain-free controls taking OC underwent 3 experimental pain procedures at 4 phases during each of 3 menstrual cycles. These procedures included algometer palpations at fixed amounts of pressure and pressure pain thresholds at several body sites, and an ischemic arm pain task. Repeated measures analysis of variance was used to compare cycle phase, TMD group, and OC status differences in experimental pain response. RESULTS: Significant phase-related differences were seen for palpation intensity measures (P values < .05). Normally cycling women with TMD showed higher palpation pain intensity at menses and midluteal phases, while women with TMD taking OC showed stable palpation pain intensity ratings at menses, ovulatory, and midluteal phases, with increased intensity at the late luteal phase. TMD subjects had greater palpation pain and ischemic pain intensity and lower pressure pain thresholds compared to controls. CONCLUSION: Phase-related differences in experimental pain response were not strong and were more often found for experimental stimuli with greater clinical relevance (ie, palpation pain) compared with an ischemic pain task.

Catastrophizing is associated with clinical examination findings, activity interference, and health care use among patients with temporomandibular disorders.

AIMS: To examine whether catastrophizing is associated with clinical examination findings, pain-related activity interference, and health care use among patients with pain related to temporomandibular disorders (TMD). METHODS: Patients with TMD (n = 338; 87% female; mean age, 37 years) completed measures of pain, pain-related activity interference, health care use, and depression, and received a Research Diagnostic Criteria/ Temporomandibular Disorders (RDC/TMD) clinical examination from an oral medicine specialist. RESULTS: Catastrophizing was not significantly associated with the more objective clinical examination measures of maximum assisted jaw opening and jaw-joint sounds, but it was associated with the more subjective examination measures (unassisted opening without pain, extraoral muscle site palpation pain severity, joint site palpation pain severity) and with increased TMD-related activity interference and number of health care visits (P values for all < .01). Even after controlling for demographic variables, pain duration, and depression severity, catastrophizing remained significantly associated with extraoral muscle and joint site palpation pain severity and with activity interference and number of health care visits. CONCLUSION: TMD patients who catastrophize have higher scores on clinical examination measures reflecting more widely dispersed and severe pain upon palpation of TMD-related facial muscle and joint sites, as well as greater TMD-related activity interference and health care use. Clinicians should consider screening patients with moderate or greater TMD pain and activity interference for catastrophizing. Cognitive-behavioral interventions may help reduce pain, disability, and health care use of patients who catastrophize.

Musculoskeletal orofacial pain and other signs and symptoms of temporomandibular disorders during pregnancy: a prospective study.

AIMS: To describe the course of reported musculoskeletal pain in the temporomandibular region and other signs and symptoms of temporomandibular disorders (TMD) as well as psychological distress over the course of pregnancy and 1 year postpartum. METHODS: Women with musculoskeletal orofacial pain (n = 19) and pain-free comparison subjects (n = 16) in the first trimester of pregnancy were selected through records review from the population of a large health maintenance organization. Subjects completed a self-administered questionnaire assessing pain, depression, and somatic symptoms; provided a sample of whole unstimulated saliva; and underwent a standardized clinical examination during the third, sixth, and ninth months of pregnancy and 1 year postpartum. RESULTS: At baseline (third month of pregnancy), 16 of the 19 patients with musculoskeletal orofacial pain met criteria for an RDC/TMD diagnosis. Reported musculoskeletal orofacial pain diminished significantly during the second or third trimester of pregnancy and increased again postpartum. Measures of mandibular opening increased over pregnancy in both cases and comparison subjects and remained high postpartum. Depression and somatic symptoms changed little over the course of pregnancy but were substantially lowered at 1 year postpartum for both groups. As expected, subjects with pain had higher levels of palpation pain, diminished mandibular range of motion, and higher levels of psychological distress compared to subjects without orofacial pain. CONCLUSION: Musculoskeletal orofacial pain and related symptoms appear to improve over the course of pregnancy. This improvement occurs in the presence of increased joint laxity and is not paralleled by improvements in psychological distress. Thus, it was concluded that the improvement in pain is most likely associated with the dramatic hormonal changes occurring during pregnancy.

Use of the Research Diagnostic Criteria for Temporomandibular Disorders for multinational research: translation efforts and reliability assessments in The Netherlands.

AIMS: To outline the steps taken to conduct and to culturally adapt Dutch translations of the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) history questionnaire, clinical examination form, and verbal instructions to the patients, and to assess the reliability of the clinical examination. METHODS: For the linguistic translation from English into Dutch, the forward and back-translation approach was followed. For cultural adaptation, an expert panel reviewed the translation, and a pretest was performed on a small clinical sample. Examiner training and calibration were carried out, and the clinical reliability of a "gold standard examiner" and 3 clinicians was assessed on 18 symptomatic TMD patients and 6 asymptomatic controls. The order of the examinations was based on a quasi-random Latin square design. Intraclass correlation coefficients (ICCs) were calculated to assess the overall interexaminer reliability of the clinical examination. RESULTS: A linguistically valid and culturally equivalent translation of the RDC/TMD into Dutch resulted from the above-outlined procedure. As for the clinical reliability, the ICC values obtained could mostly be considered "excellent" or, less frequently, as "fair to good." Poor reliability was found only for some of the palpation tests. For uncommon diagnoses (disc displacement without reduction and without limited mouth opening; osteoarthritis), no reliable ICC value could be calculated. CONCLUSION: The mode described by the authors for preparing clinical sites for RDC/TMD-based research is a feasible one.

Chronic intermittent ethanol exposure reduces presynaptic dopamine neurotransmission in the mouse nucleus accumbens.

BACKGROUND: Increasing evidence suggests that chronic ethanol exposure decreases dopamine (DA) neurotransmission in the nucleus accumbens (NAc), contributing to a hypodopaminergic state during withdrawal. However, few studies have investigated adaptations in presynaptic DA terminals after chronic intermittent ethanol (CIE) exposure. In monkeys and rats, chronic ethanol exposure paradigms have been shown to increase DA uptake and D2 autoreceptor sensitivity. METHODS: The current study examined the effects of ethanol on DA terminals in CIE exposed mice during two time-points after the cessation of CIE exposure. DA release and uptake were measured using fast scan cyclic voltammetry in NAc core slices from C57BL/6J mice, 0h and 72h following three weekly cycles (4 days of 16h ethanol vapor/8h room air/day+3 days withdrawal) of CIE vapor exposure. RESULTS: Current results showed that DA release was reduced, uptake rates were increased, and inhibitory D2-type autoreceptor activity was augmented following CIE exposure in mice. CONCLUSIONS: Overall, these CIE-induced adaptations in the accumbal DA system reduce DA signaling and therefore reveal several potential mechanisms contributing to a functional hypodopaminergic state during alcohol withdrawal.

Brief group cognitive-behavioral intervention for temporomandibular disorders.

Temporomandibular disorders (TMD) are currently viewed as an interrelated set of clinical conditions presenting with signs and symptoms in masticatory and related muscles of the head and neck, and the soft tissue and bony components of the temporomandibular joint. Epidemiologic and clinical studies of TMD confirm its status as a chronic pain problem. In this report we present results from a randomized clinical trial which compared, at 3- and 12-month follow-ups, the effects of usual TMD treatment on TMD pain and related physical and psychological variables with the effects of a cognitive-behavioral (CB) intervention delivered to small groups of patients before usual TMD treatment began. The purpose of this study was to determine whether a minimal CB intervention followed by dental TMD treatment enhanced the effects of usual clinical dental treatment. A second purpose of the study was to determine whether patients classified as high in somatization and psychosocial dysfunction would respond less favorably to this minimal intervention than would those low in somatization and dysfunction. Patients who participated in the CB intervention followed by usual treatment showed greater long-term decreases in reported pain level and pain interference in daily activities than did patients who received only usual treatment. The benefits of CB intervention were not seen when the CB and UT groups were compared at 3-month follow-up. During the 3-12-month follow-up interval, however, the UT group maintained essentially the same level of improvement in characteristic pain while the CB group continued to improve, as hypothesized. During this same follow-up interval, the CB group also showed a strong trend toward continued improvement in pain interference. Such effects were not observed for depression, somatization, or clinical measures of jaw range of motion. Additionally, as hypothesized, dysfunctional chronic pain patients did not appear to benefit from the brief CB intervention. Intent to treat analyses were also performed to assess generalizability of the results.

The relationship of somatization and depression to experimental pain response in women with temporomandibular disorders.

OBJECTIVE: Patients with temporomandibular pain disorders (TMD) have greater experimental pain perception when compared with pain-free controls. Common psychological features of TMD include somatization and depression. The impact of depression on experimental pain perception has received considerable attention. However, the role of somatization on experimental pain in a chronic pain population has not been explored. METHODS: Fifty-six women with TMD and 59 pain-free controls underwent three experimental pain procedures, including palpation at fixed amounts of pressure, pressure pain thresholds, and an ischemic pain task. Levels of depression and somatization were assessed using the Research Diagnostic Criteria for TMD. Multiple regression analyses were performed to determine the extent to which depression and somatization were associated with experimental pain response. RESULTS: After controlling for characteristic pain intensity and depression, somatization explained a significant proportion of variance in numbers of masticatory sites rated as painful (R2 change = 6.7%, p = .046) with the full model explaining 16.4% of the variance (p = .024). This did not meet an adjusted level of statistical significance (p = .008). After controlling for characteristic pain, only depression added significantly to the model predicting ischemic pain threshold and tolerance. The full models including characteristic pain and depression explained 49% and 20% of the variance in ischemic pain threshold and tolerance, respectively. CONCLUSIONS: These findings suggest that depression and somatization are associated with different measures of experimental pain. Somatization may be related to more attentional and perceptual measures of clinically relevant pain while depression may be related to more behavioral measures of pain.

Short-term clinical outcomes and patient compliance with temporomandibular disorder treatment recommendations.

AIMS: To evaluate short-term patient compliance with 5 conservative temporomandibular disorder (TMD) treatments (jaw relaxation, jaw stretching, heat application, cold application, and occlusal splint use) and the association of compliance with changes in pain intensity, pain-related activity interference, and jaw use limitations. METHODS: Eighty-one TMD patients were given 1 to 5 treatment recommendations as part of usual care in a TMD specialty clinic. Compliance with each recommendation and pain, pain-related activity interference, and jaw use limitation measures were calculated from electronic interviews conducted 3 times daily for 2 weeks. RESULTS: Median compliance with individual treatment modalities ranged from 7.7% for heat application to 92.7% for jaw relaxation; median overall compliance was 54.8%. Participants with higher initial pain intensity and jaw use limitations were significantly more compliant with their recommended treatment regimen (P < .05). The authors controlled for age, gender, education, and initial jaw use limitations. Overall compliance was associated significantly and positively with 2-week jaw use limitations (P = .03). A trend toward a statistically significant positive association was found between compliance and 2-week pain intensity (P = .09). CONCLUSION: Compliance varied widely across patients and therapies. Patients with higher initial pain and jaw use limitation levels were more compliant with treatment recommendations. Although compliance was associated with slight increases in pain and jaw use limitations in this preliminary study, further research is needed to evaluate the longer-term effects of compliance with recommended therapies.

A randomized clinical trial of a tailored comprehensive care treatment program for temporomandibular disorders.

AIMS: To test the usefulness of tailoring cognitive-behavioral therapy (CBT) for patients with temporomandibular disorders (TMD) who demonstrated poor psychosocial adaptation to their TMD condition, independent of physical diagnosis. METHODS: A randomized clinical trial compared a 6-session CBT intervention delivered in conjunction with the usual TMD treatment to the usual conservative treatment by TMD specialist dentists. For study inclusion, Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD), Axis II criteria, were used to target patients with elevated levels of TMD pain-related interference with daily activities, independent of physical diagnosis (i.e., Axis I). RESULTS: At the post-treatment assessment, about 4 months after the baseline evaluations, the comprehensive care group, when compared to the usual treatment group, showed significantly lower levels of characteristic pain intensity, significantly higher self-reported ability to control their TMD pain, and a strong trend (P = .07) toward lower pain-related interference in daily activities. From post-intervention to 1-year follow-up, all subjects showed improvement. At the 1-year follow-up, the comprehensive care group, while not losing any of its early gains, was not significantly different from the usual care group with regard to reported levels of pain, ability to control pain, and levels of interference in activities. For many of these psychosocially disabled TMD patients, pain and interference 1 year after treatment remained at the same or higher levels than those observed at baseline among a group of patients selected for a separate randomized clinical trial on the basis of better psychosocial adaptation. CONCLUSION: The 6-session CBT intervention for patients with heightened psychologic and psychosocial disability was effective in improving pain-related variables over the course of the CBT in conjunction with usual treatment, but was too brief an intervention to result in further improvement after the sessions ended. Patient ratings of treatment satisfaction and helfulness were high for both groups, but they were significantly higher for the comprehensive care group.

A randomized clinical trial using research diagnostic criteria for temporomandibular disorders-axis II to target clinic cases for a tailored self-care TMD treatment program.

AIMS: To carry out a randomized clinical trial (RCT) contrasting usual conservative treatment of TMD by clinical TMD specialists with a structured self-care intervention, targeted to clinic cases independent of TMD physical diagnosis, who were reporting minimal levels of psychosocial dysfunction; the intervention was delivered by dental hygienists in lieu of usual treatment. METHODS: The Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) was used to target subjects who exhibited minimal TMD-related psychosocial interference. Criteria for study inclusion were: (1) self-report of facial and/or masticatory muscle pain discomfort for which usual care was prescribed by the clinic TMD specialist; (2) RDC/TMD Axis II graded scale of chronic pain (GCP) score of 0, I, or II-Low. (3) Age 18 to 70 years. RESULTS: On 1-year follow-up, while both groups showed improvement in all clinical and self-report categories measured, patients in the tailored self-care treatment program compared to usual TMD treatment showed significantly; (a) decreased TMD pain, (b) decreased pain-related interference in activity; (c) reduced number of masticatory muscles painful; (d) fewer additional visits for TMD treatment. Groups were comparable with regard to measures of vertical range of motion. The self-care program was associated with consistent, but non-statistically significant, trends towards lower levels of depression and somatization. Ability to cope with TMD, knowledge concerning TMD and patient satisfaction was significantly enhanced for the self-care group. No participating patients experienced physical or personal adverse effects during the 1-year post-treatment follow-up period. CONCLUSION: Use of RDC/TMD psychosocial assessment criteria can contribute to successful clinical decision-making for the management of TMD.
