The microstructure and surface morphology of radiopaque tricalcium silicate cement exposed to different curing conditions

Nov 28, 2017 by in Dental Materials Comments Off on The microstructure and surface morphology of radiopaque tricalcium silicate cement exposed to different curing conditions

Abstract Objective Tricalcium silicate is the major constituent phase in mineral trioxide aggregate (MTA). It is thus postulated that pure tricalcium silicate can replace the Portland cement component of MTA….

Nondestructive monitoring of the repair of enamel artificial lesions by an acidic remineralization model using polarization-sensitive optical coherence tomography

Nov 28, 2017 by in Dental Materials Comments Off on Nondestructive monitoring of the repair of enamel artificial lesions by an acidic remineralization model using polarization-sensitive optical coherence tomography

Abstract Objectives It is difficult to completely remineralize carious lesions because diffusion into the interior of the lesion is inhibited as new mineral is deposited in the outermost layers. In…
