Korean Medicine Clinical Practice Guideline Update for Temporomandibular Disorders: An Evidence-Based Approach

Abstract

Many updated clinical research results have been published since the Korean Medicine Clinical Practice Guidelines (KMCPGs) for temporomandibular disorders (TMDs) were published in 2018. Therefore, it is necessary to update the existing clinical practice guidelines (CPGs). This study presents updated recommendations for TMD treatment based on current research data published up to February 2020. The draft version of the level of evidence and grade of recommendation was determined through an assessment of the risk of bias and a meta-analysis of selected literature based on the Grading of Recommendations Assessment, Development, and Evaluation (GRADE). The final guidelines were derived using the Delphi method. Eighteen recommendations were derived for eight items of Korean medicine treatment for TMDs. Compared with previous Korean medicine CPGs for TMDs, the grades of seven recommendations, including acupuncture, pharmacopuncture, and Chuna manual therapy, were increased. The grades of the two recommendations have been changed. Six new recommendations were added to fully reflect clinical reality. Acupuncture, pharmacopuncture, and Chuna manual therapy are recommended for TMD patients in clinical practice. Concurrent conventional conservative therapy with Korean medicine or a combination of Korean medicines should be considered in clinical practice in patients with temporomandibular disorders.
