Surfactant Protein D Levels in GCF Before and After MINST in Periodontitis

NCT07599657 · Status: RECRUITING · Phase: NA · Type: INTERVENTIONAL · Enrollment: 18

Summary

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.

Conditions

  • Periodontitis
  • Periodontitis Stage II
  • Periodontitis Stage III

Interventions

PROCEDURE

Minimally Invasive Non-Surgical Periodontal Therapy

Minimally invasive non-surgical periodontal therapy will include oral hygiene instructions, supragingival plaque control, and subgingival instrumentation using fine periodontal instruments, miniature Gracey curettes, thin ultrasonic tips, magnification when available, and local anesthesia when needed. Debridement will be performed for periodontal pockets while minimizing trauma to the soft tissues.
