Surfactant Protein D Levels in GCF Before and After MINST in Periodontitis
Recruiting now · Not applicable
Conditions studied: Periodontitis, Periodontitis Stage II, Periodontitis Stage III
In brief
This study will evaluate changes in Surfactant Protein D (SP-D) levels in gingival crevicular fluid (GCF) of patients with periodontitis before and after minimally invasive non-surgical periodontal therapy (MINST). Participants diagnosed with stage II or III periodontitis will receive minimally invasive non-surgical periodontal treatment. GCF samples will be collected at baseline and 6 months after treatment, and SP-D levels will be measured using enzyme-linked immunosorbent assay (ELISA). The study will also assess clinical periodontal outcomes, including full-mouth plaque score, full-mouth bleeding score, probing pocket depth, clinical attachment level, gingival recession, and patient satisfaction. Each participant will serve as their own control by comparing baseline values with 6-month post-treatment values.
