Using modified USPHS criteria, we evaluated annually for ten years 91 cases restored with visible light cured posterior composite resin LFP (Base resin: UDMA; filler: micro crushed type, alumino-silicate, barium glass and silica, 85 wt%, 74 vol%). The 91 cases restored with LFP decreased to 68 in ten years. Of the 23 cases that were lost, one resulted from a pulpal reaction immediately followin...

AIM To investigate the pulp chamber penetration of bleaching agent in intact teeth and teeth following restorative procedure. METHODOLOGY Sixty extracted human incisors were selected and divided into 6 Groups. Four Groups were restored with hybrid composite resin and resin modified glass ionomer cement respectively, while 2 Groups were left intact. The Groups were then immersed in the treatme...

PURPOSE To identify how different treatments of the root dentin surface affect the microscopic appearance of the resin composite/glass-ionomer cement-to-dentin interface. METHODS The root canals of 70 extracted human single-rooted teeth were enlarged to reduce dentin wall thicknesses to 0.5 mm. The roots were randomly divided into seven test groups (n=10) according to the canal irrigant used:...

Objective(s): The aim of this study was to synthesis new dental nanocomposites reinforced with fabricated glass nanoparticles and compare two methods for fabrication and investigate the effect of this filler on mechanical properties. Materials and Methods: The glass nanoparticles were produced by wet milling process. The particle size and shape was achieved using PSA and SEM. Glass nanoparticle...

In this study, we aimed to demonstrate changes in the surface roughness and microhardness of three different restorative materials routinely used pediatric dentistry (composite, compomer resin-modified glass ionomer cement (RMCIS)) response continuous daily exposure gastric acid. Twelve samples each type material were prepared. Eleven specimens included acid cycle. The ten measured before after...

UNLABELLED The purpose of this systematic review was to quantitatively find out whether resin-modified glass-ionomers (RM-GIC), in comparison to fluoride-containing composite resin and composite resin without fluoride, are associated with a more effective reduction of demineralization in hard tooth tissues under caries challenge. Five databases were systematically searched on clinical trials up...
