Clinical Trial Summary

Preliminary clinical studies have confirmed that injection of freshly prepared HA35 can reduce symptoms and signs of gingivitis or periodontitis. This clinical study is a prospective repeated experiments. The purpose of this study was to verify the effectiveness of HA35 injection therapy.

Description:

The previous studies showed that toothpastes containing the cosmetic grade raw material of the 35 kDa low molecular hyaluronan fragment HA35 significantly reduced symptoms and signs of gingivitis or periodontitis. In this study, patients with mild to moderate periodontitis suffering from symptoms and signs, including discomfort and swelling and bleeding of periodontal tissue, were treated by intrapocket injection of freshly manufactured hyaluronan fragment HA35. This study is an repeat clinical study comparing pre- and posttreatment effects similar to others.

Intervention

Drug:
• Freshly manufactured 35 kDa hyaluronan fragment
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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	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
Primary	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
Primary	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
