Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Following baseline assessments, participants in the gingivitis and periodontitis groups will receive standard non-surgical periodontal therapy. Periodontal clinical measurements will be repeated at the 3-month follow-up visit in these groups. In accordance with the existing ethics committee approval and following further feasibility assessment, an additional blood sample will be collected at the 3-month follow-up visit exclusively from participants in the periodontitis group.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Gingivitis Patients

Participants with visible signs of gingival inflammation and bleeding on probing, but without clinical attachment loss or radiographic bone loss. These individuals will receive standard non-surgical periodontal therapy.

Non-surgical Periodontal Therapy

Intervention Type PROCEDURE

Standard full-mouth supra- and subgingival debridement performed in a single session, followed by oral hygiene instructions.

Stage III/IV Periodontitis Patients

Participants diagnosed with stage III or stage IV periodontitis, characterized by clinical attachment loss, probing depth ≥5 mm, and radiographic bone loss. These individuals will receive standard non-surgical periodontal therapy and will be re-evaluated at 3 months.

Non-surgical Periodontal Therapy

Intervention Type PROCEDURE

Standard full-mouth supra- and subgingival debridement performed in a single session, followed by oral hygiene instructions.

Periodontally Healthy Individuals

Participants with no clinical signs of gingival inflammation, probing depth ≤3 mm, no clinical attachment loss, and no radiographic bone loss. These individuals serve as the healthy control group.

Non-surgical Periodontal Therapy

Intervention Type PROCEDURE

Standard full-mouth supra- and subgingival debridement performed in a single session, followed by oral hygiene instructions.
