Effect of different tetra pack juices on microhardness of direct tooth colored-restorative materials.

Purpose: To examine the effect of apple and orange juices on the surface hardness of direct tooth-colored restorative materials.

Materials And Methods: The materials included resin-modified glass ionomer cement (Vitremer 3M™ ESPE™ Core buildup restorative) and composite resin (Filtek™ 3M™ ESPE™ Z350). A total of 45 disks of each restorative material were prepared.

Effectiveness of commonly available surface protecting agents in maintaining microhardness of two cements.

Objective: To estimate the microhardness of glass ionomer cement (vitrofil) and resin modified glass ionomer cement (vitremere) in the presence and absence of different surface protections.

Study Design: An in-vitro experimental study.

Place And Duration Of Study: The Department of Operative Dentistry, Dr.
