Efficacy and Safety of HA35 Gel for Mild Gingival Recession and Periodontal Inflammation (HA35-PERI)

7. maj 2026 opdateret af: Nakhia Impex LLC

A Prospective, Single-Arm, Open-Label Pilot Clinical Study to Evaluate Efficacy and Safety of Topical 10% 35 kDa Hyaluronan (HA35) Gel for Mild Gingival Recession and Chronic Periodontal Inflammation

This is a prospective, single-arm, open-label, pilot clinical study to evaluate the efficacy and safety of topical 10% high-concentration 35 kDa hyaluronan (HA35) gel in subjects with mild gingival recession and chronic periodontal inflammation. Eligible participants will apply the HA35 gel topically to the gingival and tooth surfaces twice daily for 42 consecutive days. The primary objectives are to assess changes in gingival recession, chronic gingival or radicular pain, gingival redness and swelling, and brushing-induced bleeding. Safety and local oral tolerability will be evaluated throughout the treatment period. This is a minimal-risk, non-pharmacological, non-invasive oral care intervention.

Detaljeret beskrivelse

This prospective, single-center, single-arm, open-label pilot clinical study investigates the efficacy and safety of topical 10% high-concentration 35 kDa hyaluronan (HA35) gel for improving mild gingival recession (Miller Class I/II) and chronic periodontal inflammatory symptoms including gingival pain, redness, swelling, and brushing-induced bleeding.

Eligible subjects will perform routine tooth brushing followed by gentle topical application of HA35 gel to the gingival margin, teeth, and affected gingival areas for approximately 3 minutes, twice daily (morning and evening) for 42 consecutive days.

Outcome assessments include measurement of exposed root surface length (gingival recession), chronic gingival/radicular pain (NRS 0-10), gingival itching/discomfort, redness and swelling scores, and incidence of brushing-induced bleeding at baseline, 30 seconds after first application, Day 2, Day 4, and Day 42.

Oral irritation, allergic reactions, and adverse events will be monitored continuously for safety assessment.

This is a non-invasive, non-pharmacological oral topical intervention with minimal risk to participants. All procedures will be conducted in accordance with the Declaration of Helsinki, and written informed consent will be obtained from all subjects prior to enrollment.

Baseline to Day 42
Change in Gingival Itching/Discomfort Intensity (0-10 NRS)
Tidsramme: Baseline to 30 seconds after first application
Change in gingival itching or discomfort intensity, assessed using a 0-10 Numeric Rating Scale (NRS), where 0 = no discomfort and 10 = maximum discomfort.
Baseline to 30 seconds after first application
Change in Gingival Redness and Swelling Severity (0-10 Scale)
Tidsramme: Baseline to Day 4
Change in gingival redness and swelling severity, assessed using a 0-10 ordinal scale, where 0 = normal gingiva and 10 = severe redness and swelling.
