“…30 32 34 35 37 It is possible that the use of a single classification standard would improve the comparison between them, however, in general, it was observed that the extent and location of tooth loss, despite being heterogeneous, do not seem to have influenced the final result, as most of them did not show a relationship between tooth loss and TMD. Most of these studies investigated loss of posterior teeth, perhaps this pattern of loss has been the most investigated, as there are records suggesting that the lack of teeth in the posterior region could generate overload and alterations in the TMJ, 45 46 although other studies have not found this relationship. 47 48 It is important to emphasize that there were no samples of completely edentulous patients in the studies included in this review.…”

Updating The General Practitioner on The Association Between Teeth Loss and Temporomandibular Disorders: A Systematic Review

2022

The belief about a possible association between the absence of one or more teeth and the presence of temporomandibular disorders (TMD), although old, is still present among the dental class. Although evidence points to a lack of association between loss of posterior support and the presence of TMD, we do not have critical studies on the extent, quantity, or location of these losses. In this sense, this systematic review aims to investigate the association between tooth loss and the presence of TMD signs or diagnostic subgroups. Search strategies using a combination of keywords tooth loss and TMDs were performed in six databases (PubMed, Embase, Web of Science, Livivo, Lilacs, and Scopus) and gray literature from August to September 2020. Observational studies that investigated the association between tooth loss in TMD were considered. The risk of bias was assessed using the Joanna Briggs Institute (JBI) Critical Assessment Checklist for cross-sectional analytical studies, case–control, and cohort studies. Finally, the level of certainty measured by the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) was assessed. Six articles were included in the review according to the eligibility criteria. Of these, five had a high risk of bias and one had a moderate risk. Only one study showed an association between the loss of posterior teeth and the presence of joint sounds and joint pain, the others found no significant association with sign or TMD subgroups diagnostic.There is no scientific evidence to support the association between one or more tooth loss and the presence of TMD signs and symptoms or diagnostic subgroups.
