Data confidence 70 medium

How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

Objective: This study aims to compare the short-, medium-, and long-term efficacy of trigger point local anesthetic injection and stabilization splint use for myofascial orofacial pain.Materials and Methods: Group 1 comprised 15 patients who received trigger point local anesthetic injections (LAI), while Group 2 comprised 15 patients who were treated with a stabilization splint (SS). Retrospective analysis of pain-free maximum mouth opening (MMO) measurements, jaw disability checklists (JDC), short-form McGill pain questionnaires (SF-MPQ), and Visual analog scales (VAS) were used for comparison between the groups.Results: The LAI group showed a significantly greater increase in pain-free MMO in all terms (p<0.001) and had significantly lower values on the JDC in both the medium (p=0.026) and long term (p=0.006). The SF-MPQ was significantly lower in the medium term (p=0.001) in LAI group; the VAS showed a significantly greater decrease in the short (p=0.016) and medium terms (p<0.001) in LAI group.Conclusion: The results indicate that a treatment choice can be made between TN lidocaine injection and occlusal splint based on patient tolerance.
