Title For a Patient with Closed Lock and Bruxism, Arthrocentesis Plus a Stabilization Appliance is More Effective Than Arthrocentesis Alone in Increasing Range of Motion
Clinical Question For a middle-aged patient with a closed lock and bruxism, would arthrocentesis in conjunction with a stabilization appliance compared to arthrocentesis alone, be more effective in reducing TMD pain and dysfunction 1 year after treatment?
Clinical Bottom Line In patients with closed lock and bruxism, arthrocentesis in conjunction with a stabilization appliance is more effective in reducing TMD pain and dysfunction 1 year after treatment in comparison to arthrocentesis treatment alone.

Key resultsThere was a significant (P<0.001) increase in the maximal mouth opening, contra-lateral movement, and protrusive movement in long-term follow up for patients who received a stabilization appliance following arthrocentesis. There was a significant decrease (P<0.019) in these measurements in patients who underwent arthrocentesis only. Both pain and dysfunction values significantly decreased (P<0.001) following treatments.

Comments on
The Evidence
It was assumed this was a randomized controlled trial, that had groups similar at the start, the groups were treated similarly, and had over 80% completion rate. There was adequate follow up and compliance. The study was not double-blind, there were no competing interests reported, and recall bias is unlikely.
Applicability Patients with bruxism should be treated with arthrocentesis in conjunction with a stabilization appliance because it is the most effective way to reduce TMD pain and dysfunction.
