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

상세 설명
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.

|
Change in Gingival Recession Depth (mm)
기간: Baseline to Day 42
|
Change in gingival recession depth, measured in millimeters (mm) using a calibrated periodontal probe.
Baseline measurement is the distance from the cementoenamel junction (CEJ) to the gingival margin.

Change in Chronic Gingival/Radicular Pain Intensity (0-10 NRS)
기간: Baseline to Day 42
|
Change in chronic gingival or radicular pain intensity, assessed using a 0-10 Numeric Rating Scale (NRS), where 0 = no pain and 10 = worst imaginable pain.
|
Baseline to Day 42
|
|
Change in Gingival Itching/Discomfort Intensity (0-10 NRS)
기간: 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)
기간: 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.
|
Baseline to Day 4
|
|
Resolution Rate of Brushing-Induced Gingival Bleeding
기간: Baseline to Day 2
|
Proportion of participants with complete resolution of brushing-induced gingival bleeding, defined as no bleeding observed during gentle tooth brushing.
|
Baseline to Day 2
|
|
Incidence and Severity of Oral Adverse Events
기간: Throughout the 42-day treatment period
|
Number and severity of treatment-related oral adverse events, including irritation, ulceration, or allergic reactions, assessed by clinical observation and participant report.
Severity graded using the Common Terminology Criteria for Adverse Events (CTCAE).
