About this trial

This observational clinical study aims to investigate the relationship between the HALP score (Hemoglobin × Albumin × Lymphocyte / Platelet), several blood-based inflammatory indices (including NLR, PLR, LMR, and SII), and salivary MMP-8 levels in individuals with periodontal health, gingivitis, and stage III/IV periodontitis. The study also evaluates how these biomarkers relate to healing following non-surgical periodontal therapy.

A total of 180 participants aged 18-65 years will be included: 50 healthy individuals, 50 patients with gingivitis, and 80 patients with stage III/IV periodontitis. All participants will undergo periodontal clinical examination and provide blood and saliva samples at baseline. Individuals in the gingivitis and periodontitis groups will receive standard non-surgical periodontal treatment (full-mouth debridement) and will return for a 3-month follow-up visit, where periodontal measurements will be repeated. In the periodontitis group, an additional blood sample will be collected at the 3-month follow-up visit.

The primary objective is to determine whether baseline HALP score, systemic inflammatory indices, and salivary MMP-8 levels differ between participants who show good versus poor healing after treatment. Secondary objective include comparing biomarker levels across periodontal status groups. The findings may contribute to early prediction of treatment response and personalized periodontal care.

Eligibility criteria

This trial accepts healthy volunteers

Qualifiers

Adults aged 18-65 years

Ability to provide informed consent

No systemic diseases or conditions affecting periodontal status

For Healthy Group: Probing depth ≤3 mm, no attachment loss, no radiographic bone loss

Disqualifiers

Systemic diseases influencing periodontal inflammation (e.g., diabetes, autoimmune disorders)

Trial population

Adult individuals aged 18-65 years presenting to the periodontology clinic for routine examination or periodontal treatment. Participants will be assigned to healthy, gingivitis, or stage III/IV periodontitis groups based on periodontal diagnosis.
