This trial tests whether using a larger, expandable balloon during cryoablation for paroxysmal atrial fibrillation better affects the heart's autonomic (automatic) control compared to a standard-size balloon. About 40% of patients show signs of beneficial parasympathetic denervat…

This trial tests whether injections of platelet-rich fibrin (iPRF), made from a patient's own blood, can reduce pain and improve jaw function in people with mild to moderate temporomandibular joint (TMJ) degeneration. Forty-two adults with TMJ arthritis or osteoarthritis will rec…

This study is testing whether a drink containing CBD and CBN can reduce facial pain and headaches caused by muscle tension. 42 adults with pain lasting over 3 months will be randomly assigned to receive either the CBD/CBN drink or a placebo. Researchers will measure pain and musc…

This observational study compares eating behaviors—such as picky eating, food neophobia, and texture preferences—between children with drug-resistant epilepsy who follow a ketogenic diet and healthy children. Researchers also measure body composition and resting metabolic rate in…

This study looks at tiny particles called exosomes, taken from a patient's own platelet-rich plasma, to see if they might help repair jaw joints. Researchers will compare these exosomes with other blood products in lab tests on cells. The goal is to understand their content and p…

This study looks at adults with temporomandibular disorders (TMD) — problems with the jaw joint and muscles — to measure how chronic pain, anxiety, depression, and perceived stress relate to each other. Researchers will use standard questionnaires to assess pain severity, depress…

This study looks at 50 adults with sleep bruxism (teeth grinding during sleep) to understand how it affects sleep, pain, anxiety, and overall health. Researchers will use sleep tests, blood samples, and questionnaires to find links between bruxism and other conditions. The goal i…

This study looks at whether dopamine levels and certain genes affect the risk and severity of sleep breathing disorders like sleep apnea. Researchers will monitor 100 adults overnight and take blood samples to measure dopamine and check for genetic variations. The goal is to bett…

This study examines the links between sleep bruxism (teeth grinding during sleep) and sleep quality, heart health, thyroid function, and mood. Researchers will give some participants opipramol, a drug that may reduce grinding activity, and monitor them with sleep tests. The goal …

This study explores whether the levels of certain receptors (CB1, CB2, TRPV-1) in the blood are linked to chronic orofacial pain from jaw muscles. Researchers will compare 102 adults with and without this pain, using blood tests and clinical exams. The goal is to understand how t…

This study looks at how chronic jaw muscle pain relates to genetics, blood chemicals, and emotional state. Researchers will compare 102 adults with and without jaw pain to find connections. No treatment is given; the goal is to better understand the condition.
