Outcomes of therapeutic TMD interventions on oral health related quality of life: A qualitative systematic review

Objectives: This systematic review aims to determine the impact of temporomandibular disorder (TMD) therapeutic interventions on patients' oral health related quality of life (OHRQoL) and to recommend approaches that improve QoL. Data Sources: A systematic search of the literature was performed between January 2007 and October 2017 to identify articles on TMD interventions and OHRQoL. Randomized controlled trials, and retrospective and prospective cohort studies that mentioned dedicated tools for measurement of OHRQoL changes in TMD patients after therapeutic interventions were included. Abstracts of studies that did not mention any form of measurement of OHRQoL in their treatment outcome were excluded. The initial screening yielded 171 articles. After evaluation of abstracts and full text articles, five articles fulfilled all selection criteria and were included. Most TMD treatment interventions seem to improve QoL to some extent, but no single treatment modality can be advocated as the sole approach to managing TMD. Conclusion: Psychotherapy, occlusal appliance therapy, arthrocentesis, and orthodontics/orthognathic surgery (in subjects with severe malocclusion) appear to improve OHRQoL of TMD patients. Recommendation on the best TMD intervention for improving QoL could not be made due to the diverse TMD subtypes and non-disease specific OHRQoL instruments employed. More studies incorporating TMD-specific OHRQoL measures and targeting explicit TMD subtypes based on internationally accepted diagnostic criteria are warranted in this area of research.
