Run by University of Minnesota · NCT07153107 · Data updated 2026-11-12

Is this trial a fit for you?

Likely a good fit

Adults 18+ with chronic TMD pain and myofascial/masticatory muscle involvement, meeting dental status and screening criteria, and able to provide informed consent.

Probably not a fit

Individuals who do not show a reduction in pain or fatigue with heat therapy or do not meet response criteria may not experience benefit.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

The trial investigates the effect of local heat therapy on jaw pain and fatigue in people with chronic TMD who perform a teeth clenching task. Participants will receive local heat treatment and outcomes will include changes in jaw pain and fatigue, with analyses comparing responders to non-responders to identify distinguishing clinical features. This is a pilot study led by the University of Minnesota to characterize which clinical factors predict a favorable response. The study envisions recruiting adults aged 18 and older with definite myofascial TMD pain and relevant dental status per protocol. No results are provided in the description yet.

Why it matters

Potential benefit: If successful, participants who respond to heat therapy may experience reduced jaw pain and fatigue during clenching.

How similar studies have gone: Prior work in related pain conditions suggests heat therapy can provide short-term relief, but this specific approach for chronic TMD phenotyping is exploratory.
