Introduction: The prevalence of Temporomandibular Disorders (TMD) tends to be higher among women. The severity of their symptoms is related to the age of the patients, in the case of women with a peak between 20-40 years. Objective: The objective of this study is to carry out a literature review regarding the role of estrogens in joint musculoskeletal disorders. Method: The online search engine PubMed was used with the terms MeSH "Temporomandibular Joint Disorders" and "Estrogens" together with the Boolean term "AND". Results: We observed a positive relationship between the levels of estrogen and the presence of muscular and articular disorders, with higher prevalence among women. Conclusions The role of estrogen in muscle and joint disorders is based mostly on correlations between one and the other, but the mechanism by which they would be associated is not entirely clear.
