Abstract: The present invention relates to a compound having antibacterial properties suitable for use as an antibacterial monomer, a photopolymerizable composition which includes said compound, and use thereof in a dental procedure.

Abstract: The present invention concerns the preparation of chemically modified derivatives of chitosan with acrylic groups and their use in the field of enamel-dentin adhesives. Chitosan derivatives have physical-chemical features (hydrophilicity, presence of electrical charges on the chain) which allow them to interact with the organic part of the demineralized tooth. At the same time, the acrylic groups incorporated in the polymer chain allow the formation of a covalent bond with the restorative material used in the dental field that is typically composed of acrylic resins. By combining the adhesion to the tooth surface and the bond with the restorative material, the chemically modified chitosan described herein is able to increase the lifespan of the dental restoration and can thus find use in the field of adhesives, in particular enamel-dentin adhesives.

Abstract: Disclosed are compositions and methods of using such compositions for inhibiting matrix metalloproteinase activity in dental tissue. The compositions, methods and uses may prevent degradation of the bonding between restorative materials and dental tissues, thereby increasing durability and longevity of the restorative material-dental tissue bonds. For example, the compositions, methods, and uses of the present invention may be used for treating carious dental tissue such as by the creation of dental fillings, crowns, bridges, among other techniques, as well as the creation of esthetic laminate restorations.
