Outcome Measures
Primary Outcomes (1)
The Efficacy in the Treatment of TMJ and Muscle Pain
The efficacy in the treatment of TMJ and muscle pain is measured by a visual analogue scale (VAS). The VAS consists of a 100 mm line, anchored with the extremes of pain intensity represented as "no pain" ( 0 mm) and " worst pain possible" ( 100 mm).

Eligibility Criteria
You may qualify if:
- Self report of facial ache or pain in the muscles of mastication, the TMJ, or the region in front of ear or inside the ear
- Positive clinical diagnosis of TMDs. The TMD diagnosis is classified using axis I of the research diagnostic criteria ( RDC) for TMDs. The RDC diagnosis consists of joint pain at rest ( spontaneous pain) and evoked pain (hyperalgesia) on palpation of the TMJ, TMJ reduction consists of reciprocal clicking or joint noise with mandibular movement examination.
- For joint pain complaint, subjects will be required to have a self-report of at least 1 month of daily or nearly-daily pain.
You may not qualify if:
- Subjects with infectious arthritis, crystal induced arthropathies, musculoskeletal disorders, subjects with a primary diagnosis of myofascial pain based on the RDC;
- Subjects with pain attributable to confirmed migraine or head pain condition other than tension headache;
- Subjects with acute infection or other significant disease of teeth, ears, eyes, nose or throats; subjects with untreated depressive disorder or not on stable antidepressant medication for more than 6 months;
- Subjects with dental diseases that required ongoing treatment, which would confound the evaluation of orofacial pain;
- Subjects who are not competent in giving consents.
- Pregnant or lactating women
- Subjects with sensitivity to the ingredient of Ping On Ointment will be excluded.
