Localized reduction of gingival inflammation using site-specific therapy with a topical gingival patch

Area of Science:

• Periodontology
• Oral Inflammation
• Biomaterials

Background:

• Chronic periodontitis is characterized by gingival inflammation.
• Current treatments like scaling and root planing are effective but invasive.
• Novel topical treatments are needed to manage gingival inflammation.

Purpose of the Study:

• To evaluate the efficacy of a novel topical gingival patch in reducing gingival inflammation.
• To assess the impact of the patch on neutrophilic activity and clinical signs of inflammation.

Main Methods:

• A pilot study involving 26 patients with moderate-to-severe chronic periodontitis.
• Gingival inflammation sites were treated with a topical patch or left as untreated controls for 24 hours.
• Inflammation was measured by gingival crevicular fluid (GCF) beta-glucuronidase (b-glu) levels and the gingival index (GI).

Main Results:

• Patch placement significantly reduced GCF b-glu levels compared to controls (p = 0.002), with a 29.7% reduction from baseline.
• Untreated control sites showed an increase in mean b-glu levels and percent change from baseline.
• The gingival index (GI) response rate was also better in the patch-treated group (p = 0.053).
• No adverse events were reported.

Conclusions:

• The topical gingival patch demonstrated a reduction in gingival inflammation.
• This novel treatment warrants further clinical investigation for managing gingival inflammation.
