What this Trial Is About
Researchers are studying how chronic temporomandibular disorder (TMD) pain affects drinking patterns in heavy drinkers. This study compares individuals with and without chronic TMD pain to understand how pain influences alcohol use, both in a laboratory setting and during daily life. It aims to fill gaps in knowledge about risk factors related to pain and alcohol consumption. Participants are assigned to one of four groups based on TMD diagnosis and the type of drink given: ethanol (alcohol) or sparkling water as a control. The groups include people with TMD who receive ethanol, people with TMD who receive sparkling water, people without TMD or chronic pain who receive ethanol, and people without TMD or chronic pain who receive sparkling water. This randomized study evaluates drinking behaviors and pain responses during the interventions. During the study, participants will be observed for alcohol use patterns and heat pain intensity over 30 minutes. They will complete questionnaires and laboratory procedures, and researchers will monitor drinking topography and pain levels. The study runs from May 2025 to September 2029, involving adults aged 21 to 65 who regularly consume alcohol. Safety and adherence are monitored, and assessments occur in both controlled and daily environments to capture real-world drinking behavior.
