Jaw-Tinnitus link under the scanner: new study hopes to uncover clues
NCT ID NCT07460193
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study investigates the connection between temporomandibular joint (TMJ) disorders and tinnitus (ringing in the ears). Researchers will use 3D jaw imaging and hearing tests in 50 adults to see if jaw bone shape and arthritis are linked to tinnitus. The goal is to better understand this relationship and improve how doctors diagnose and treat related symptoms.
