Outcome Measures

Primary Outcomes (3)

  • Measurement of gum discomfort

    Each patient rated their gingival discomfort or itching on a scale of 0 to 10. 0 means "no", and 10 means "the most".

    7 days

  • Measurement of gum redness and swelling

    The physician used the numbers 0-10 to rate the intensity of gingival redness and swelling in the subject. 0 means "no"; 10 means "highest".

    7 days

  • Measurement of probe gingival bleeding

    The physician used the numbers 0-10 to rate the extent to which the subject's probe gums were bleeding. A score of 0 indicated "no" and 10 indicated "the most"

    7 days

Study Arms (1)

HA35 local injection of Periodontal Pocket group

EXPERIMENTAL

The tissue-permeable 35 kDa low molecular hyaluronan fragment HA35 was freshly manufactured using pharmaceutical grade hyaluronidase PH20 injection (State Drug Administration H31022111) and joint cavity HA injection (State Drug Administration H20174089) mixed at room temperature for 20 min.

Drug: Freshly manufactured 35 kDa hyaluronan fragment

Interventions

The study was an open-label clinical trial. A pre- and posttreatment controlled study approach was used, whereby the investigator injected 35 kDa hyaluronan fragment HA35 into the periodontal pocket in a single dose of 100 mg. The distribution of the injection amount was determined by the location of gingival inflammation.
