background: peritoneal dialysis is one of the most prevalent types of dialysis prescribed to the patients suffering from renal failure. studies on the factors affecting the survival of these patients have mainly used log-rank test and cox analysis. the present study aimed to investigate the risk factors affecting short- and long term survival of patients on continuous ambulatory peritoneal dial...

the incorporation of boehmite nano-particles and its effects on the mechanical properties and bond strength of an experimental dental adhesive were studied.an adhesive solution containing ethanol, bis-gma, tmptma, hema and photo-initiator system (camphorquinone and dmaema) was prepared. silanized boehmite nano-particles were incorporated into the adhesive in different concentrations of 0, 0.2, ...

Erosion is one of serious oral health problems among Japanese children. Some dentists argue that brushing just after food/drink intake induces enamel abrasion. Objectives of this study were to evaluate amount of calcium elution from bovine enamel due to single and short immersion into carbonated soft drink, to calculate depth of the eroded lesion, and to determine when to brush teeth after carb...

UNLABELLED Background and aims. Today light cured composites are widely used. Physical and mechanical properties of composites are related to the degree of conversion. Light curing unit (LCU) is an important factor for composite polymerization. Aim of this study is evaluation of composite resins hardness using halogen and LED light curing units. Materials and methods. In this study, 30 samples ...
