چکیده
As a part of this study, mathematical model based on two-compartment pharmacokinetic system with general fractional derivatives was developed. Its aim to describe the release BisGMA and TEGDMA monomers from composite core resin over three time periods. For purpose, five Clearfil Photo Core samples were prepared elution measured using high performance liquid chromatography at 1, 7 28 days post-immersion in 75% ethanol. The findings confirmed good fit data related released monomer quantity.

Ultra-fast light-curing resin composite with increased conversion and reduced monomer elution.
OBJECTIVES To test the null hypotheses that photoactive resin composites containing a Type I photoinitiator would exhibit reduced DC or increased monomer elution at substantially short curing times compared with materials based on a Type 2 ketone/amine system. METHODS Two experimental resin composites were prepared, using either Lucirin-TPO or camphorquinone/DMAEMA. Specimens were light-cured...
متن کاملEffect of Food Stimulated Liquids and Thermocycling on the Monomer Elution from a Nanofilled Composite
The present study was aimed to evaluate the effects of food simulating liquids and thermocycling on the elution of monomers from a nanofilled resin composite in different immersion times. Five Specimen discs were made from a nano-hybrid composite (Supreme 3M) for each group (Total = 180) and immersed in distilled water (control), citric acid, lactic acid, and 75% aqueous ethanol solution. The d...
متن کاملDental repair material: a resin-modified glass-ionomer bioactive ionic resin-based composite.
This report documents treatment and repair of three carious teeth that were restored with a new dental repair material that features the characteristics of both resin-modified glass-ionomer restorative cement (RMGI) and resin-based composite (RBC). The restorative products presented are reported by the manufacturer to be the first bioactive dental materials with an ionic resin matrix, a shock-a...

relationship to the filler may be the solution to polymerization shrinkage and clinical challenges (i.e., shrinkage stress) that are associated with these methacrylate-based composite resin systems. Two recently developed composite-resin systems have replaced the weak linkthe matrix. A comparison of the new matrix chemistries of both systems can provide the attributes and capabilities for their...
متن کاملReview: Resin Composite Filling
The leading cause of oral pain and tooth loss is from caries and their treatment include restoration using amalgam, resin, porcelain and gold, endodontic therapy and extraction. Resin composite restorations have grown popular over the last half a century because it can take shades more similar to enamel. Here, we discuss the history and use of resin, comparison between amalgam and resin, clinic...
