Arthrocentesis with different irrigation volumes in patients with disc displacement without reduction: One-year follow-up

ABSTRACT

Objective: This study evaluated the clinical efficacy of arthrocentesis when varying the irrigation volume in patients with disc displacement without reduction (DDWOR).

Methods: Thirty DDWOR patients were equally divided into two groups: G1 (50 mL) and G2 (200 mL). Information was compared for pain, the maximum interincisal distance (MID), protrusion, and right and left laterality.

Results: Arthrocentesis was able to reduce the pain and increase the MID, protrusion, and both laterality values significantly one year after the procedure (p < 0.001) in both groups. However, comparisons between the groups revealed no significant difference (p > 0.05). Furthermore, changes in volume did not affect the arthrocentesis results (p = 0.626, odds ratio = 1.625; 95% confidence interval = 0.230–11.461).

Conclusion: Arthrocentesis techniques using 50- and 200-mL irrigation volumes were both effective, with no significant differences between techniques observed after one year of follow-up.
