Table 1_Interplay between dietary antioxidants and oxidative/nitrosative stress in stage I

A preliminary quasi-experimental study from 2026 investigates the interplay between diet and oxidative stress in 24 Mexican adults (11 with periodontitis, 13 healthy controls). The dataset, authored by Miguel A. Robledo-Valdez, includes clinical parameters, dietary assessments, and salivary/plasma biomarker measurements. It examines the effects of Non-Surgical Periodontal Therapy on oxidative/nitrosative status.

Use Cases

• Analyze correlations between nutrient intake and oxidative biomarkers based on the 30 significant nutrient-biomarker correlations reported in diseased patients.
• Model the impact of Non-Surgical Periodontal Therapy on clinical and biochemical outcomes based on pre- and post-treatment measurements.
• Investigate dietary patterns as a risk factor for periodontitis based on comparisons of energy and polyunsaturated fatty acid intake between groups.
• Study the persistence of oxidative imbalance post-treatment based on salivary MDA+4-HDA levels remaining above the healthy threshold.

Strengths

• Includes data from a calibrated clinical examination by a periodontist.
• Biomarker panel covers multiple oxidative/nitrosative pathways: Total Antioxidant Capacity, protein carbonyls, lipid peroxidation, and nitrate/nitrite.
• Dietary assessment uses a validated Semi-Quantitative Food Frequency Questionnaire (SFFQ).

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The sample size is small (24 participants), as described in the preliminary study.
