Myofascial Pain Dysfunction (MPD) is a regional muscular pain characterized by the presence of trigger points (TrPs), which are painful points cause referred pain when stimulated. There are many treatment modalities for MPD. However, no treatment has proved its superiority over the others yet.
To figure out what is the most effective treatment in relieving pain in patients with myofascial pain dysfunction (MPD) among local anesthesia, botox and trigger point dry needling.
We conducted the review according to the Cochrane methods. We searched the Cochrane Oral Health Group Trial register, Cochrane Central Register of Controlled Trials, MEDLINE, the WHO International Clinical Trial Registry Platform for ongoing studies (30 June 2018) and hand searched citation lists of relevant publications. Two review authors assessed trials for inclusion, risk of bias, extracted data, and checked for accuracy. We have expressed results as risk ratio or mean differences (MD), together with their 95% confidence intervals (CI).
We included 2 trials of 3 reports (65 participants). One trial reported pain relief immediately after injection of local anesthesia and dry needling (MD -7.00, 95% CI -32.02 to 18.02). No meta-analysis was conducted because of lack of data.
There is insufficient evidence to support the superiority of one intervention over the others or no difference among them in the treatment of MPD of muscles of mastication.
