Overview
Brief Summary
The aim of the present study was to compare the efficacy of three different treatment methods in the management of myofascial pain: masseteric nerve block (MN), trigger point injection(TrP) with local anesthetic (LA) and dry needling (DN).Study Design: 45 subjects aged 18-54 years were randomly assigned to the MN group (n= 15), LA group (n=15) and DN group (n=15).
Detailed Description
The study sample consisted 45 patients with masseter muscle originated myofascial pain, were selected in accordance with the following criteria: Patients were grouped according to the treatment they received: dry-needling (DN), TrP injections with local anesthetic (LA) and masseteric nerve block (MNB). Localization of the masseteric trigger points (MTPs) was based on clinician's sense and patients' expressions of pain. Local twitch response was not observable in all case. This procedure was completed by using digital palpation (1.5 Kg), and the clinical examiner's palpation was calibrated using a pressure algometer.

Exclusion Criteria
- •Generalized muscle disorders.
- •Hypersensitivity to local anesthetics.
Outcomes
Primary Outcomes
The Rate of Pain on Function (PoF) assessed by Numerical pain Scale (NRS)
Time Frame: At 12th week (t3)
Patients rated their pain on function (pain during chewing or speaking etc.) on a Numeric Rating Scale (NRS) (0-10 where 0 is no pain and 10 is the worst pain imaginable)
Secondary Outcomes
- The measurement of pain-free maximum mouth opening (MMO) in millimeters(At 12th week (t3))
- The Rate of Pain Intensity on Palpation (PoP)(At 12th week (t3))
