Abstract: A drug delivery system is described comprising a detachable support and a plurality of drug-loaded transdermal microneedles, for delivering drugs into gingival tissue for the treatment of periodontal disease.

Abstract: The present invention relates to biomimetic membrane compositions and methods for making and using them.

Abstract: A dental hydrogel composition comprising: (a) polysaccharide; (b) polydopamine conjugated to the polysaccharide, wherein between 5 and 35 percent of polysaccharide sugar moieties are conjugated to polydopamine; (c) RGD peptide coupled to the polysaccharide-poly-dopamine conjugate; and (d) moieties that are crosslinkable upon exposure to light coupled to the polysaccharide; wherein components (a)-(d) are disposed in the composition such that the hydrogel composition: exhibits an adhesive strength of at least 10 kPa upon cross linking of crosslinkable moieties; and exhibits an elasticity between 5 kPa and 100 kPa upon cross linking of crosslinkable moieties.

Abstract: Conventional dental cements lack certain properties such as the facilitation of optimal re-mineralization. The novel bioactive glass-ionomer dental and bone cement formulations disclosed herein induces mineralization at the in vivo interface and exhibits superior handling properties (shorter setting time) and mechanical properties (improved bond strength to dentin and flexural strength). The present invention presents the first bioactive glass-ionomer dental cement with mineralization power, exhibiting improved bond strength to tooth structure, sharp setting time and superior mechanical strength. Materials of this invention can be used as bone cement, as a dental filling (restorative material), as a liner for deep cavity preparations (to avoid root canal therapies and tooth sensitivity), or as a luting cement to cement dental crowns. Moreover, it can be utilized in a flowable resin for use as a coating to prevent dental caries in their initial steps (white spots).
