Nanoparticles Induced Biomimetic Remineralization of Acid-Etched Dentin.

Statement Of The Problem: Dentin bonding with etch-and-rinse adhesives involves demineralizing the 5-8µm of the surface dentin to create micro space for resin infiltration. The presence of continuous fluid movement in dentin tubules and positive pulpal pressure prevents complete water replacement by resin monomers. This results in areas of demineralized dentin, which contain collagen fibers without resin infiltration.

CBCT as a Novel Tool for Gender Determination using Radio Morphometric Analysis of Maxillary Sinus-A Prospective Study.
