RESUMO
INTRODUCTION: Assessment of host response to inflammation will throw light on the critical role of antioxidants (AOs) and free radicle damage in the etiology of periodontal disease. The purpose of the study was to assess the level of plasma oxidative stress in those having aggressive periodontal disease before and after full-mouth disinfection. Objectives were to find the influence of full-mouth disinfection analyzing the level of thiobarbituric acid reactive substances (TBARSs), thereby quantifying the lipid peroxidation (LPO) and also the activities of reduced glutathione (GSH), glutathione peroxidase (GPX), and catalase (CAT), valuing the AO defense systems in health and disease. MATERIALS AND METHODS: The valuation composed of 30 subjects with aggressive periodontal disease and 30 healthy controls. Clinical assessment included following periodontal parameters: plaque index (PI), papillary bleeding index (PBI), probing pocket depth (PPD), and clinical attachment level (CAL). Levels of bone loss were assessed by taking full-mouth periapical radiographs. Initial periodontal therapy comprises of full-mouth disinfection which includes subgingival scaling and root planing within 24 hours combined with adjunctive chlorhexidine chemotherapy for aggressive periodontitis subject's at sites indicated. The parameters (clinical) were evaluated at the baseline and 8 weeks after initial periodontal therapy at six sites of teeth indicated. Plasma samples were taken and evaluated by standard procedures as defined in the literature. All the values were weighed and related. RESULTS: Strong positive associations were detected among periodontal parameters and TBARS, enzymatic/nonenzymatic AO levels (p < 0.05), and pre- and postperiodontal management. The plasma levels of patients with aggressive periodontitis had high levels of TBARS and displayed a substantial escalation in the activities of GSH and GPX levels in the plasma matched to the healthy individuals (p < 0.05). CONCLUSION: This paper evaluated ROS activity and AO defense before and after treatment to stimulate added periodontal investigation in this part which will give an insight into the therapeutic options with foreseeable results.
