Brief summary

This is a prospective, single-arm, open-label, pilot clinical study to evaluate the efficacy and safety of nighttime occlusive application of 10% high-concentration 35 kDa hyaluronan (HA35) gel in subjects with temporomandibular joint disorder (TMD). Eligible participants will apply HA35 gel to the TMJ area nightly under occlusive conditions for 8-12 hours. The primary objectives are to assess rapid pain relief and muscle over-tension reduction at 60 seconds and 12 hours after application. Safety and local tolerability will be evaluated throughout the study period. This is a minimal-risk, non-pharmacological, non-invasive intervention.

Detailed description

This prospective, single-center, single-arm, open-label pilot clinical study investigates the efficacy and safety of nighttime occlusive topical 10% high-concentration 35 kDa hyaluronan (HA35) gel for relieving pain and muscle over-tension associated with temporomandibular joint disorder (TMD). Eligible subjects will apply ≥6.5 mL of HA35 gel to the TMJ region before sleep, covered with an occlusive film for 8-12 hours overnight. Pain intensity and muscle over-tension will be assessed using a 0-10 Numeric Rating Scale (NRS) at baseline, 60 seconds after application, and 12 hours after application. Local skin reactions, adverse events, and overall tolerability will be monitored continuously. This is a non-invasive, non-pharmacological intervention with minimal risk to participants. All procedures will be conducted in accordance with the Declaration of Helsinki, and written informed consent will be obtained from all subjects prior to enrollment.

Design outcomes

Primary

MeasureTime frameDescription
Change in TMJ Pain NRS Score (0-10)Baseline to 60 seconds and 12 hours after applicationChange in TMD-related TMJ pain intensity measured by 0-10 NRS, 0 = no pain, 10 = worst imaginable pain.

Secondary

MeasureTime frameDescription
Change in Jaw Muscle Over-Tension Intensity (0-10 NRS Score)Baseline to 60 seconds and 12 hours after applicationChange in jaw muscle over-tension intensity, assessed using a 0-10 Numeric Rating Scale (NRS), where 0 = no muscle tension and 10 = maximum, painful muscle over-tension.
Incidence and Severity of Local Skin Adverse EventsFrom study enrollment (baseline) to the end of the 12-hour observation periodNumber and severity of treatment-related local skin adverse events (e.g., redness, irritation, allergic reaction) reported during the study. Severity is graded using the Common Terminology Criteria for Adverse Events (CTCAE).
