TMJ, temporomandibular joint; VAS, visual analogue scale (0–10) for pain; v, visit in which intervention took place.

^*The oral intervention consisted of a 0.5-mL injection of 0.5% procaine into the submucosa at the described points.

^**The intervention of other non-oral points consisted of 1.0-mL injection of 0.5% procaine at the myofascial level of the described points.
