상세 설명
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.

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.

Boron Levels in Saliva and Gingival Tissue
기간: 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.

Oxidative Stress Markers
기간: 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
기간: 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.

Inflammatory Marker
기간: 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.
