Boron Levels, Oxidative Stress, and Inflammation in Periodontitis

RecruitingN/A

Sponsor: Marmara University

Conditions: Periodontitis

Interventions: Biochemical Assessment of Saliva and Gingival Tissue

Countries: Turkey (Türkiye)

This cross-sectional observational study aims to evaluate the relationship between boron levels and oxidative stress, antioxidant defense, and inflammatory markers in individuals with periodontitis. The study will include systemically healthy, non-smoking individuals divided into two groups: periodontally healthy controls and patients with Stage III-IV periodontitis. Boron levels and selected oxidative stress, antioxidant, and inflammatory biomarkers will be evaluated in saliva and gingival tissue samples. The findings will be compared between the groups to investigate the potential relationship between boron levels and periodontal inflammation and oxidative stress.
