Boron Levels, Oxidative Stress, and Inflammation in Periodontitis

16 août 2026 mis à jour par: Marmara University

Evaluation of the Relationship Between Boron Levels and Oxidative Stress, Antioxidant Defense, and Inflammatory Markers in Individuals With Periodontitis

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.

Description détaillée

Periodontitis is a chronic inflammatory disease characterized by the destruction of the tooth-supporting tissues and is associated with an imbalance between oxidative stress and antioxidant defense mechanisms. Boron is a trace element that has been suggested to have potential roles in antioxidant and inflammatory processes; however, its relationship with periodontal disease remains unclear.

This cross-sectional observational study will include 60 systemically healthy, non-smoking participants: 30 periodontally healthy individuals and 30 patients diagnosed with Stage III-IV periodontitis. Periodontal clinical parameters will be recorded for all participants.

Unstimulated saliva samples will be collected before periodontal surgical procedures. Gingival tissue samples will be obtained during clinically indicated periodontal surgical procedures, including crown-lengthening procedures in periodontally healthy participants and periodontal surgery in participants with periodontitis.

Boron levels will be determined in saliva and gingival tissue samples. Oxidative stress and antioxidant defense will be evaluated using selected biomarkers, including reactive oxygen species, total oxidant status, malondialdehyde, total antioxidant status, glutathione, superoxide dismutase, and catalase. Interleukin-1 beta will be evaluated as an inflammatory marker.

Boron levels and biochemical parameters will be compared between periodontally healthy individuals and participants with periodontitis, and their relationships with periodontal clinical parameters, oxidative stress, antioxidant defense, and inflammation will be investigated.

Population étudiée

The study population will consist of 60 systemically healthy individuals aged 18-65 years attending the Department of Periodontology, Faculty of Dentistry, Marmara University. Participants will be divided into two groups: 30 individuals with Stage III-IV periodontitis with an indication for periodontal flap surgery and 30 periodontally healthy individuals with an indication for crown-lengthening surgery.

Cohortes et interventions

Groupe / Cohorte
Intervention / Traitement
Periodontitis Group
Systemically healthy, non-smoking individuals diagnosed with Stage III-IV periodontitis who are scheduled for clinically indicated periodontal surgical treatment.
Unstimulated saliva and gingival tissue samples will be collected from participants. Gingival tissue samples will be obtained during clinically indicated periodontal surgical procedures. The samples will be biochemically analyzed to determine boron levels and markers of oxidative stress, antioxidant defense, and inflammation. No experimental treatment or therapeutic intervention will be administered as part of the study.
Periodontally Healthy Group
Systemically healthy, non-smoking individuals with periodontal health who are scheduled for clinically indicated crown-lengthening surgery.
Unstimulated saliva and gingival tissue samples will be collected from participants. Gingival tissue samples will be obtained during clinically indicated periodontal surgical procedures. The samples will be biochemically analyzed to determine boron levels and markers of oxidative stress, antioxidant defense, and inflammation. No experimental treatment or therapeutic intervention will be administered as part of the study.

Que mesure l'étude ?

Principaux critères de jugement

Mesure des résultats
Description de la mesure
Délai
Boron Levels in Saliva and Gingival Tissue
Délai: At the time of the clinically indicated periodontal surgical procedure
Boron levels will be measured in unstimulated saliva and gingival tissue samples obtained from participants in the periodontitis and periodontally healthy groups. Salivary boron levels will be expressed as µg/mL and gingival tissue boron levels as µg/g.
At the time of the clinically indicated periodontal surgical procedure

Mesures de résultats secondaires

Mesure des résultats
Description de la mesure
Délai
Oxidative Stress Markers
Délai: At the time of the clinically indicated periodontal surgical procedure
Oxidative stress will be assessed by measuring reactive oxygen species (ROS), total oxidant status (TOS), and malondialdehyde (MDA) levels in samples obtained from the periodontitis and periodontally healthy groups.
At the time of the clinically indicated periodontal surgical procedure
Antioxidant Defense Markers
Délai: At the time of the clinically indicated periodontal surgical procedure
Antioxidant defense will be assessed by measuring total antioxidant status (TAS), glutathione (GSH), superoxide dismutase (SOD), and catalase (CAT) levels in samples obtained from the periodontitis and periodontally healthy groups.
At the time of the clinically indicated periodontal surgical procedure
Inflammatory Marker
Délai: At the time of the clinically indicated periodontal surgical procedure
Inflammation will be assessed by measuring interleukin-1 beta (IL-1β) levels in samples obtained from the periodontitis and periodontally healthy groups.
At the time of the clinically indicated periodontal surgical procedure
