Abstract
Dental dressing assemblies are formed from hydrophilic polymer sponge structures, such as a densified chitosan biomaterial. The invention also contemplates systems and methods that can be used in conjunction with stents and periodontal dressings to promote hemostasis and secondary healing in free gingival graft palatal donor sites and all other oral and maxillofacial surgical sites.
