Summary

Oral hygiene quality is a key determinant of outcomes in both non-surgical and surgical periodontal therapy. Previous studies have demonstrated the negative impact of site-specific plaque accumulation on periodontal parameters. However, to the best of our knowledge, no studies have specifically investigated the correlation between plaque index and the percentage reduction in periodontal pocket depth, nor its association with other periodontal clinical parameters. The aim of this study is to evaluate the relationship between plaque index and the percentage reduction in periodontal pockets, as well as its association with key periodontal parameters. Following baseline data collection, patients will undergo non-surgical periodontal therapy in accordance with current guidelines. Clinical outcomes will be reassessed at 3, 6, 9, and 12 months post-treatment.

Conditions

• Periodontitis

Interventions

Type	Name	Description
PROCEDURE	Non-surgical periodontal therapy (NSPT)	Patients will receive non-surgical periodontal therapy, including professional supragingival (Step 1) and subgingival scaling and root planing (Step 2), according to current guidelines (Herrera et al., 2023). Oral hygiene instructions will be provided at baseline and reinforced at each follow-up visit. Clinical outcomes, including percentage of pocket depth reduction and plaque index (FMPS), will be recorded at 3, 6, 9, and 12 months post-treatment.
