Abstract

We aimed to find out the association of total antioxidant capacity (TAC) and total oxidant status (TOS) with generalized pressure pain thresholds (PPT) of patients with myofacial pain dysfunction (MPD). PPT scores of patients with MPD (n 37) and healthy individuals (n 43) were measured on the hypothenar region of the hand using a mechanical algometer. Serum samples were collected and TAC and TOS were measured by novel methods. The TAC of patients was significantly lower than that of the control subjects. The difference between the TOS measurements of patients and control subjects was not significant. The PPT scores of the patients were significantly lower than that of control subjects. There may be an association between serum antioxidant capacity and MPD. Low serum TAC might also be related with pain perception. © 2009 Informa UK Ltd All rights reserved.
