Abstract
Persistent pain at the site of injection is the most common complication of local
anesthesia in the oral cavity. The complication of trismus after local anesthetic
injection is rare and may be prevented by the use of short needles for maxillary posterior
injections, and by the avoidance of multiple injections in a short period of time.
Once trismus develops, its progression to chronic hypomobility and fibrous ankylosis
may be prevented by the early institution of treatment consisting of heat, analgesics,
muscle relaxants, and exercises.
