What is a key precaution before administering intra-articular corticosteroid injections into the TMJ?

• A. Intra-articular corticosteroid injections should be avoided if there is an active infection in the TMJ or systemic infection
• B. They are always safe regardless of infection
• C. They should be given before any conservative therapy
• D. They have no contraindications

Answer: (C)

A key precaution is to rule out an active infection in the TMJ or a systemic infection before giving an intra-articular corticosteroid injection. Corticosteroids suppress the immune response, so injecting into a joint that is infected can allow the infection to worsen or spread and can lead to septic complications. If infection is present or suspected, treat and clear it first, then reassess for injection. In practice, conservative therapies are usually tried first for TMD, and injections are considered after those approaches have been tried or for specific, indicated cases. The emphasis here is safety and appropriate sequencing, not performing the injection before exhausting noninvasive options. Additional safety checks include confirming correct intra-articular placement, and considering other contraindications such as bleeding risk or uncontrolled systemic conditions.
