Intra-pocket Injection of a Freshly Manufactured 35 kDa Hyaluronan Fragment HA35 Reduces the Gingival Discomfort as Well as Gingival Redness and Bleeding of Patients With Periodontitis: A Clinical Study
Intra-pocket Injection of a Freshly Manufactured 35 kDa Hyaluronan Fragment HA35 Reduces the Gingival Discomfort as Well as Gingival Redness and Bleeding of Patients With Periodontitis: A Clinical Study
The main objective of this study is to research the treatment of 35 kDa hyaluronan fragment HA35 for Mild periodontitis and associated with gingival discomfort or itchiness.
In this study, 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.
In this study, 20 patients, 8 males, and 12 females, with a mean age of 47±15 years, were selected from the outpatient clinic of the Department of Dentistry. All had mild periodontitis and were associated with gingival discomfort or itchiness. Injection treatment was performed using freshly manufactured 35 kDa hyaluronan fragment HA35. The study was an open-label clinical trial in which no information was withheld from the participating investigators. A pre- and post-treatment controlled study approach was used, whereby the investigator injected 35kDa hyaluronan fragment HA35 into the periodontal pocket in a single dose of 100 mg. The distribution of injection amount was determined by the location of gingival inflammation. The clinical effects of gingival discomfort or itching, redness and swelling, and bleeding from the probing were observed and recorded in patients before and after 7 days of treatment.
