7 Clinical Trials for Various Conditions
Temporomandibular disorders (TMDs) involve a range of conditions with varied causes, affecting a large portion of the U.S. population and posing challenges for diagnosis and management, especially in chronic cases. Despite advances in understanding TMD pathophysiology, the role of central sensitization, particularly deficient endogenous pain inhibition, remains unclear. The conditioned pain modulation (CPM) test, used to assess pain inhibition in chronic TMD pain, has produced inconsistent results due to varying testing parameters. The proposed cross-sectional study will investigate the efficiency of endogenous pain inhibition in individuals with chronic TMD pain compared to controls by applying noxious and non-noxious stimuli to facial and non-facial sites. The findings aim to clarify the impact of weaker pain inhibition over the face, how the conditioning stimulus' painfulness affects inhibition and the relationship between pain inhibition and fluctuations in TMD pain intensity.
The goal of this clinical trial is to learn whether a 2-week gratitude journaling activity is feasible and acceptable for individuals with Temporomandibular Disorder (TMD) and chronic overlapping pain. The study will also look at whether this activity is helpful in reducing pain and how much it interferes with daily life. The primary aims of this study are to: * Assess whether individuals with TMD and chronic overlapping pain are able to complete the 2-week gratitude journaling activity as planned (feasibility). * Evaluate how acceptable participants find the gratitude journaling activity (acceptability). The secondary aim of this study is to: • Explore whether the gratitude journaling activity reduces pain and its impact on daily life, compared to a general wellness journaling activity. Participants will: * Attend two in-person visits to complete questionnaires and take part in tests that measure how sensitive they are to pressure and heat. * Complete a 2-week journaling activity at home, writing in their journal on three days of their choice per week.
Individuals with chronic temporomandibular disorder (TMD) pain are at increased risk for alcohol-related consequences compared to those without pain, and growing evidence suggests pain is a potent motivator for alcohol use in many individuals. However, few systematic examinations of modifiable and non-modifiable risk factors, including orofacial pain status, have been conducted. This project addresses this gap in knowledge by determining the effect of pain on drinking topography in heavy drinkers with and without chronic TMD pain in both the laboratory and daily life.
This project examines, in chronic pain, the mechanisms of immersive virtual reality compared to the mechanisms of placebo hypoalgesia. The potential of developing new non-pharmacological premises for low-risk interventions for pain management is high.

Temporomandibular/orofacial pain disorders (TMD) are a group of painful conditions with multiple determinants.This proposal has two main goals: 1) to test a highly individualized, adaptive treatment for TMD that has potential to be more effective than other psychosocial treatments; and 2) to discover the mechanisms by which psychosocial treatments work in chronic pain. TMD patients (N=160) will be randomized to receive standard care (STD) + an individualized assessment and treatment program (IATP) or to standard care + conventional cognitive-behavioral treatment (STD+CBT). It is expected that the STD+IATP treatment will yield lower pain, depression and interference scores over time than STD+CBT, and that changes in coping ability will mediate the treatment effects on outcomes.
This study will examine the effectiveness of injected hylan (Synvisc) for treating pain associated with osteoarthritis of the temporomandibular joint (jaw joint) and improving function of the joint. Hylan is a synthetic product very similar to a component of normal healthy joint fluid (synovial fluid), which is present in much lower quantities and is abnormal in osteoarthritis. Hylan injections have been beneficial in treating osteoarthritis of the knee. Patients with temporomandibular (TMJ) joint pain of at least 3 months duration who have mouth opening limitation and moderate to severe joint pain made worse by joint movement may be eligible for this study. Patients must not have any TMJ growth disturbances and must not have had any TMJ surgery for 6 months before entering the study. Candidates are screened with questionnaires, a medical history, and a physical examination of the TMJs, including x-rays and magnetic resonance imaging. Participants are randomly assigned to receive three injections, each a week apart, of either Synvisc or placebo (a salt-water solution) into the affected joint. Before the first injection, a sample of synovial fluid is collected from the joint by needle aspiration for laboratory analysis. Patients return for follow-up visits 3, 6, and 12 months after the last treatment for a clinical examination of the jaw joint and review of jaw joint symptoms. A second aspiration is requested at the 3-month visit, but is not mandatory. All injections and aspirations are done after anesthetizing the overlying skin and joint capsule to minimize pain or discomfort. Participants record their daily use of pain relief medication throughout the study.
