Brief Summary

Periodontitis is a chronic immunoinflammatory disease that has been increasingly associated with systemic conditions, particularly type 2 diabetes mellitus (T2DM). Trace elements such as chromium (Cr), magnesium (Mg), and nickel (Ni) play important roles in metabolic regulation, insulin signaling, inflammatory responses, and tissue integrity. Alterations in the serum levels of these elements have been reported in T2DM; however, their relationship with periodontal status remains poorly understood. This cross-sectional observational study aims to evaluate serum Cr, Mg, and Ni levels in individuals with T2DM and chronic periodontitis and to investigate their potential associations with periodontal clinical parameters.

Outcome Measures

Primary Outcomes (1)

  • Serum levels of chromium, magnesium, and nickel

    The primary outcome is the assessment of fasting serum chromium, magnesium, and nickel concentrations measured using atomic absorption spectrometry in individuals with type 2 diabetes mellitus with and without chronic periodontitis, and systemically healthy controls.

    Single time point (cross-sectional assessment)

Secondary Outcomes (3)

  • Periodontal clinical parameters

    Single time point

  • Association between serum trace element levels and periodontal parameters

    Single time point

  • Effect of glycemic control on serum trace element levels

    Single time point

Study Arms (4)

Control group

Systemically and periodontally healthy individuals.

Other: No intervention (Observational study)

Periodontitis group

Systemically healthy individuals with Stage II, Grade B periodontitis.

Other: No intervention (Observational study)

Controlled T2DM with periodontitis group

Individuals with HbA1c \< 7.0 and Stage II, Grade B periodontitis.

Other: No intervention (Observational study)

Uncontrolled T2DM with periodontitis group

Individuals with HbA1c ≥ 7.0 and Stage II, Grade C periodontitis.

Other: No intervention (Observational study)

Interventions

Participants were not assigned to any therapeutic or preventive intervention. The study involved periodontal examination and blood sample collection for serum trace element analysis only.

Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

The study population consists of adult individuals aged 18 years and older who were systemically evaluated at the Department of Endocrinology and Metabolism and subsequently referred for periodontal examination. Participants include systemically and periodontally healthy individuals as well as patients diagnosed with chronic periodontitis, with or without type 2 diabetes mellitus. Eligible participants were allocated into study groups based on periodontal status and glycemic control.

You may qualify if:

  • Adults aged ≥18 years
  • Having at least 20 natural teeth, excluding third molars
  • Diagnosed with type 2 diabetes mellitus or systemically healthy, according to group allocation
  • Willingness to participate in the study and provision of written informed consent

You may not qualify if:

  • Presence of systemic diseases other than type 2 diabetes mellitus (e.g., renal or hepatic failure, cardiovascular disease, organ transplantation, or current or previous cancer treatment)
  • Use of antibiotics, non-steroidal anti-inflammatory drugs, corticosteroids, immunosuppressive drugs, calcium channel blockers, beta blockers, oral contraceptives, or anticoagulants within the last 3 months
  • History of non-surgical periodontal treatment within the last 6 months or periodontal surgery within the last 12 months
  • Pregnancy or lactation
  • Body mass index (BMI) ≥ 30 kg/m²
  • Current smoking or alcohol consumption
  • Use of vitamin, mineral, or antioxidant supplements within the last 3 months
