Outcome Measures

Primary Outcomes (2)

  • Plaque accumulation

    This was assessed using O'Leary plaque index. The O'Leary Plaque Index records the presence or absence of dental plaque on four surfaces (mesial, distal, buccal, lingual) of each tooth. The score ranges from 0% (no plaque) to 100% (plaque on all surfaces), with lower percentages indicating better oral hygiene.

    up to 12 weeks

  • Gingival condition assessment

    The Gingival Index of Löe and Silness was used to assess the severity of gingival inflammation based on color, consistency, and bleeding on probing across four areas per tooth. Scores range from 0 (normal gingiva) to 3 (severe inflammation with spontaneous bleeding), with higher scores indicating worse gingival health.

    up to 12 weeks

Secondary Outcomes (2)

  • Probing depth

    up to 12 weeks

  • Clinical attachment loss

    up to 12 weeks

Other Outcomes (1)

  • Microbiological assessment of P. gingivalis

    6 weeks

Study Arms (2)

Scaling and root planing with sodium hypochlorite and hyaluronic acid

EXPERIMENTAL
Other: Scaling and root planing with sodium hypochlorite and hyaluronic acid

Scaling and root planing

ACTIVE COMPARATOR
Procedure: Scaling and root planing

Interventions

Sodium hypochlorite gel was applied first for 30 seconds, then followed by subgingival instrumentation of the site. Then, 1.8% hyaluronic acid (1.6% cross-linked, 0.2% natural hyaluronic acid ) was applied subgingivally into the periodontal pocket to seal the site.

Scaling and root planing with sodium hypochlorite and hyaluronic acid

Pockets were treated with sub-gingival scalling and root planning alone.
