Effectiveness of Toothpaste Containing REFIX Technology against Dentin Hypersensitivity: A Randomized Clinical Study.

Aim: This clinical study aimed to evaluate the efficacy of a toothpaste containing a proprietary REFIX technology (Regenerador + Sensitive DentalClean, Rabbit Corp) against dentin hypersensitivity.

Materials And Methods: Fifty-three volunteers who fulfilled the inclusion criteria and signed the consent form were included. They were examined for dentin hypersensitivity.

Effect of two processing techniques used to manufacture lithium disilicate ceramics on the degree of conversion and microshear bond strength of resin cement.

The aim of the current study was to compare the effect of two lithium disilicate ceramic processing techniques (pressing and CAD/CAM) on the degree of conversion of resin cement when it is photoactivated and the microshear bond strength of resin cement to ceramics. Two ceramic discs were manufactured: one by the Press technique and another by CAD/CAM technique. Five Variolink Veneer resin cement samples were photoactivated through each ceramic disc and subjected to attenuated total reflectance Fourier transform infrared spectroscopy to evaluate their degree of conversion.
