BACKGROUND Polymer infiltrated ceramics and nano-ceramic resins are the new restorative materials which have been developed in order to enhance the adverse properties of glass-matrix ceramics and resin composites. The aim of the present in vitro study was to evaluate the characteristics of various CAD/CAM materials through mechanical, microstructural, and SEM analysis. METHODS Five test group...

Background: Selection for fall dormancy (FD) in alfalfa (Medicago sativa) can impact other traits, including dry matter yield (DMY), winter survival rate (WSR) and nutrient compositions. The current study was aimed to screen varieties with greater yield, good quality strong ability thus are more suitable planting Heilongjiang, China may be similar upper-latitude semiarid environments the world....

Abstract Objective The effect of polymerization time and resin shade on the depth cure (DOC) two nano-hybrid composites (Filtek Z250 XT IPS Empress Direct) was evaluated compared. Materials Methods Sixty specimens were prepared from shades (A1 A3) composites. allocated into groups that further divided three subgroups depending (20, 40, 60 sec; n = 5). After that, DOC by calculating polymerized ...
