RESUMO
INTRODUCTION: Periodontitis is a common problem affecting a significant population of the world. For the assessment of oxidative stress of an individual, total oxidation status (TOS) and total antioxidant capacity (TAOC) are the significant biomarkers. Hence, we planned the present study to assess malondialde-hyde (MDA), TOS, TAOC levels, and oxidative stress index (OSI) in generalized aggressive periodontitis (GP) and chronic periodontitis (CP) patients. MATERIALS AND METHODS: The present study included assessment of 40 CP patients, 40 GP patients, and 40 healthy controls. Clinical assessment of all the subjects was done by measuring the probing depth (PD), clinical attachment (CL), gingival index (GI), gingival bleeding index (GBI), and plaque index (PI). Salivary and serum samples were taken and assessed by standard procedures as described previously in the literature. All the values were assessed and compared. RESULTS: Significant results were obtained while comparing all the periodontal parameters in between various study groups. Mean serum MDA levels in the CP, GP, and control group were found to be 0.68, 0.65, and 0.61 µM respectively. Statistically nonsignificant results were obtained while comparing the serum MDA levels in between the three study groups. Significant results were obtained while comparing the mean serum and salivary TOS values, TAOC values, and OSI in between various study groups. CONCLUSION: In periodontitis patients, oxidative stress was significantly higher in comparison with healthy subjects. CLINICAL SIGNIFICANCE: Oxidative parameters do play a significant role in the pathologic profile of periodontitis.
