Clinical factors affecting the outcome of arthocentesis

Objectives This study aimed to evaluate the effect of clinical factors on the outcome of arthrocentesis in the treatment of temporomandibular joint (TMJ) internal derangement. Materials and Methods Fifty patients with TMJ internal derangement underwent arthrocentesis using ringer's lactate. The present study evaluated the contribution of the clinical variables of age, time since onset, visual analogue scale (VAS) pain level, and range of motion (ROM) on the outcomes of TMJ arthrocentesis: age (≤25 years, >25 and ≤40 years, >40 and ≤60 years), VAS pain level (≤5, >5 and ≤7, >7 and ≤10), and ROM (7 (OR, 11.25; P=0.039), and a maximum vertical opening of
