First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a special gel (HA35) applied to the jaw at night to relieve pain and muscle tightness from temporomandibular joint disorder (TMD). About 30 adults with TMD will use the gel nightly for 8-12 hours. Researchers will check how well it reduces pain and tension after 60 seconds and 12 hours, and monitor for any skin reactions.
