INTRODUCTION In recent years, significant developments have been taking place in caries removal and cavity preparation using laser in dentistry. As laser use is considered for cavity preparation, it is necessary to determine the quality of restoration margins. Glass ionomer cements have great applications for conservative restoration in the pediatric field. The purpose of this in vitro study wa...

BACKGROUND Hydroxyapatite (HA) is the main mineral component of the tooth structure, which exhibits considerable biological behavior and its incorporation might improve microhardness of dental materials. Microhardness of restorative materials, like glass-ionomer, is critical for the clinical longevity of restorations. The aim of this study was to evaluate the microhardness of two glass-ionomers...

INTRODUCTION Recent advances in dental materials have led to the production of smart materials. Recently, addition of bioactive materials to glass-ionomer cements has resulted in new capabilities beyond the beneficial effects of fluoride release. This in vitro study compared the flexural strengths (FS) of a resin-modified glass-ionomer containing bioactive glass (RMGIBAG) with that of a commonl...

Abstract Graphene is extensively used as a functional material due to its superb heat transfer and electrical conductivity properties. In this paper, sample graphene oxide /glass fiber/epoxy resin composites were prepared by ultrasonic decentralization. The stress distribution of the graphene-doped fiber-reinforced matrix simulated mathematical modelling. reliability numerical model illustrated...
