Study summary

This is a prospective, single- center, randomized (1:1) clinical trial comparing the effectiveness of magnesium sulphate injections in treatment of myofascial trigger points in the masseter muscle versus the saline injection.

Read the detailed description

The proposal presents the magnesium sulphate (MgSO4) as a possible injection treatment for TrPs. The MgSO4 prevents the release of pre-synaptic acetylcholine from neuromuscular and sympathetic junctions that could explain the ability of the MgSO4 to relax the muscle and reduce pain Specific aim: evaluate the effectiveness of magnesium sulphate injections in treatment of myofascial trigger points in the masseter muscle versus the saline injection.

Hypothesis: the injection of masseter muscle trigger points with magnesium sulphate is more effective than saline injection in pain relief.

What researchers measure

Primary outcomes

  1. pain score

    pain score measured on a 10-point visual analogue scale (VAS), the 0 indicating no pain and 10 indicating the worst pain ever.

    Time frame: 6 months postoperative

Secondary outcomes

  1. quality-of-life in an Oral Health Impact Profile questionnaire (OHIP-14)

    OHIP-14 is used to measure patients' self-reported discomfort, disability, and functional limitation due to oral conditions with scores ranging from 0 to 56 (with 56 representing a subject answering ''very often'' to all 14 items)

    Time frame: six months postoperative
