Wound Healing Clinical Trial
Official title:
A New Drug Delivery System - Silk Fibroin Film Loaded or Not With Insulin on Palatal Mucosa Wound Healing: in Vitro Study and a Randomized Clinical Trial.
The aim of the present study is to evaluate using clinical, patient-centered, immunological, microbiological, and histological parameters, the effect of silk fibroin films loaded or not with insulin in the repair of palatal mucosa open wounds.
There are several types of periodontal and peri-implant soft tissue defects that require surgical treatment to reestablishment function and aesthetics. Therefore, surgical procedures for the reconstruction of the gingival and peri-implant tissues are routinely performed. However, these procedures do not always have predictable outcomes, and problems with the wound healing process can occur, which can impair the outcomes. To overcome this problem, new materials, drugs, and devices have been used to improve the results of surgical procedures. The present study is a controlled clinical trial that will include seventy-five patients with an indication of anterior maxillary tooth extraction for ridge preservation. The ridge preservation will be performed and a free gingival graft harvest from the palatal mucosa will be used to seal the socket entrance. Thereafter, the palatal wound will be randomly assigned into 3 groups: Control Group (C; n=25): open wound on palatal mucosa that will receive no treatment. Blank Film Group (BF; n=25): open wound on palatal mucosa that will receive silk fibroin film as dressing. Insulin-loaded film (IF; n=25): open wound on palatal mucosa that will receive an insulin-loaded silk fibroin film as a delivery system. Clinical, immunological, histological, and microbiome parameters will be analyzed. ;
