Objectives: Temporomandibular dysfunction (TMD) is a group of disorders in the facial region and temporomandibular joint (TMJ). Biomarkers are assumed to play a role in pain and early detection of destruction. The aim of this study was to compare the saliva and serum antioxidant levels in patients with TMD and healthy subjects. Materials and Methods: This case-control study was conducted on 28 TMD patients with- out pain, 28 TMD patients with pain and 28 healthy controls. The total antioxidant capacity of saliva and serum of patients was measured. Data were analyzed using ANOVA and Tam-hane’s test. Results: The mean (±SD) total antioxidant capacity of serum (plasma TAC) was 0.8900 (±0.11627) mmol/L in TMD patients with pain, 1.2717 (±0.18711) mmol/L in TMD patients without pain and 1.7500(±0.18711) mmol/L in the control group.  Based on ANOVA, the difference in this regard among the 3 groups was statistically significant (P=0.000). The mean  salivary TAC  was  1.34  (±0.06721) mmol/L in  TMD  patients  with  pain,  1.42 (±0.16677) mmol/L in TMD patients without pain and 1.35 (±0.11627) mmol/L in the con- trol group. The difference in this respect among the 3 groups was not significant (P>0.05). Conclusion: The mean plasma TAC in TMD patients with/without pain was significantly lower than that in the control group but no significant difference was detected in salivary TAC among the three groups.
