Total oxidant status and total antioxidant capacity in the saliva of patients with chronic periodontitis
Tóm tắt
Background: Recently, methods of quantifying total oxidant status (TOS) and total antioxidant capacity (TAOC) were developed to investigate periodontitis. This study was performed to evaluate the salivary TOS and TAOC levels of patients with chronic periodontitis (CP) and investigating the association between periodontal clinical parameters and these oxidative stress biomarkers.
Material and methods: 40 participants (23-65 years old) were classified into two groups of 20 each, namely the CP group (participants with CP) and the control group (periodontally healthy controls). Clinical periodontal parameters were monitored, and TOS and TAOC levels were measured using laboratory assays.
Results: TOS level increased in the saliva of patients with CP and the salivary TAOC in patients with CP was significantly lower than that of the control group. The TOS had a positive moderate correlation with the plaque index and clinical attachment loss (r=0.32 and 0.37, respectively) while TAOC was negatively and moderately correlated with clinical attachment loss (r=-0.35).
Conclusion: Salivary TOS and TAOC were distinguished in healthy and chronic PD patients. Further studies are required to comprehensively evaluate the potential role of these biomarkers in diagnosis and treatment evaluation of CP.
