STATEMENT OF PROBLEM The degree of conversion depends on the material composition, light source properties, distance from light source, light intensity, curing time, and other factors such as shade and translucency. OBJECTIVES In the present study, we evaluated the effects of different light-curing modes and shades of methacrylate and silorane-based resin composites on the degree of conversio...

Rapid hardening sulphoaluminate cement has been widely studied and applied under low temperature, normal temperature high conditions, but the research negative conditions just started. Through three curing methods: constant curing, changing positive pre-curing, influence of different methods on compressive strength rapid mortar at -10 °C is discussed. The results show that pre-curing measures c...

Dental caries is one of the chronic disease oral cavity with a prevalence 45,3% in indonesia. Fluoride substance that could help preventing carries and secondary carries. can also be found restorative materials used dentistry release fluoride ions inside cavity. The aim this study to determine differences different curing time on giomer’s release.The method experimental laboratory design using ...

OBJECTIVES The aim of this in vitro study was to evaluate the influence of different light curing units and modes on microleakage of flowable composite resins. METHODS Eighty Class V cavities were prepared in buccal and lingual surfaces of 40 extracted human premolars with cervical wall located in dentin and the occlusal wall in enamel. These teeth were randomly assigned into two groups (n=20...

BACKGROUND Although using light-cured composites for bonding orthodontic brackets has become increasingly popular, curing light cannot penetrate the metallic bulk of brackets and polymerization of composites is limited to the edges. Limited access and poor direct sight may be a problem in the posterior teeth. Meanwhile, effectiveness of the trans-illumination technique is questionable due to in...

OBJECTIVE The aim of this study was to compare the polimerization ability of three different light-curing units (quartz tungsten halogen, light-emitting diodes and plasma arc) and their exposure modes (high-intensity and soft-start) by determination of microhardness, water sorption and solubility, and diametral tensile strength of 5 dual-curing resin cements. MATERIAL AND METHODS A total of 7...

Automotive topcoat curing is critical to the quality of the final coating. In production, topcoat curing quality is commonly judged through the evaluation of sample panel temperature-time series data from the finished product directly against the cure window that is specified for the polymeric coating material used. This inspection-based post-process quality control (QC) is not only methodologi...
