Overview
The goal of this clinical trial is to evaluate the efficacy of topical 2.5% hydrocortisone in TMJ arthralgia. The main questions it aims to answer are:
- How does pain reduction compare?
- How does improvement in jaw function limitation compare?
- How do side effects compare? Participants will
- On day 1 be examined and report their pain level and jaw function limitation
- On days 1-21, apply their cream four times a day
- On day 21, report their pain level, jaw function limitation, compliance with instructions, and side effects.
Researchers will compare topical 2.5% hydrocortisone and topical 1% diclofenac to see if efficacy and side effects differ.
Description
- Person 2 will label creams, patient packets (pre-stamped envelope, questionnaire,
consent form), and give packets to Person 1 in the order in which they are to be
dispensed.
- Person 1 will recruit all eligible patients in the order in which they are seen, enrolling all that consent. Packets and gel will be given to patient, and written and verbal instructions, including that email will be sent saying "Keep it up!" to remind them to continue applying get, as well as "Please send us your questionnaire".

- Person 1 will send complete anonymized Excel data file (containing all patients) to Person 3
- Person 2 will determine, using random number generator, which group will be referred to as "Group A" during the statistical analysis, and which will be referred to as "Group B"
