Haplotypes of the RANK and OPG genes are associated with chronic arthralgia in individuals with and without temporomandibular disorders

The aim of this study was to evaluate the association between genetic polymorphisms and the comorbid presence of chronic systemic arthralgia in patients with articular temporomandibular disorders (TMD). Subjects were evaluated for the presence of TMD and asked about the presence of chronic joint pain. Four groups were included in the study: articular TMD and systemic arthralgia (n=85), no articular TMD and systemic arthralgia (n=82), articular TMD and no systemic arthralgia (n=21), no articular TMD and no systemic arthralgia (control, n=72).
