Abstract:

The objective was to evaluate the change in color, hardness, and roughness produced by carbamide peroxide (CP) at two different concentrations on two resins. The 16% or 45% CP was applied to 66 resin discs with and without Bis-GMA. The color was measured with a spectrophotometer, and ΔEab and ΔE00 were calculated. Microhardness tester and SEM were used. In both composites, the a* and b* coordinates tended to be red and yellow, respectively, and were significant in the Bis-GMA group (p < 0.05). The ΔEab and ΔE00 were higher in the composite with Bis-GMA, regardless of the treatment received

Background: Residual monomers are non-polymerized monomers which can cause clinical harm, for example inflammation, to oral cavity tissue while the remaining monomers can potentially be carcinogenic.

ABSTRACT Composite resin materials are most widely used in dentistry today, to fill anterior and posterior teeth. The properties of composite resin are physical properties, mechanical properties, and chemical properties. The properties of composite resin can be affected by low pH (acid). The effect of acidic pH can cause matrix degradation and erosion of composite resin, thus affecting compressive strength, surface hardness, and wear rates. Various previous studies have proven the effect of acidic pH on the mechanical properties of composite resin. The purpose of writing this literature study

Abstract:

After long-term use of resin materials for dental repair, plaque is easy to accumulate on the surface to form biofilms, which can cause caries. Although antibacterial agents are applied to oral resins, the antibacterial ability, mechanical performance, and biocompatibility of the material have to be considered. In this study, the cationic polymer NPVP with different lengths of alkyl chain is adopted to modify the carbon–nanodiamond (CND), and hydroxyethyl methacrylate (HEMA) is introduced to reduce the cytotoxicity of the modified particles and improve the compatibility with the resin matrix.

Abstract:

We studied relaxation by hygroscopic expansion of the interfacial polymerization shear stress of bonded resin composites. In the experimental set-up, resin composite-cured-to-glass strips bent due to the polymerization shrinkage. The strips were stored wet or dry. The curvatures of the bent strips were recorded, by the scanning of the glass surfaces with a contact profilometer, periodically over a period of two months. From the measured deflections, we calculated the maximum tangential bending stress in the resins near the adhesive interface, which provided an estimation for the maximum shear

Abstract:

The preset shape and diameter of a prefabricated FRC post rarely follows the anatomy of the root canal. To solve this problem, a new hollow sleeve composite (HSC) system for post-core construction was developed and characterized. A woven fiber was impregnated with two types of resins: Bis-GMA or PMMA, and rolled into cylinders with outer diameter of 2 mm and two different inner diameters, namely 1.2 or 1.5 mm. The commercial i-TFC system was used as a control. Dual-cure resin composite was injected into these sleeves. Additionally, conventional solid fiber post was used as the inner part of th

Abstract:

Biocompatibility is one of the major prerequisites for safe clinical application of materials. Dental resin composites may release their components into oral environment, which can lead to adverse reactions. Several studies have identified that many organic components of composites resin, such as bisphenol-A-glycidyl-methacrylate (Bis-GMA), triethylene glycol dimethacrylate (TEGDMA), urethane dimethacrylate (UDMA) and 2-hydroxyethyl methacrylate (HEMA) show a cytotoxic profile. Cytotoxicity is mainly sustained by free monomers released after polymerization process. Direct restorations are poly

Abstract:

Background: One of the composite resin composition is inorganic filler. The production of inorganic filler materials was highly dependent on non-degradable, and nonrenewable fossil fuels. Therefore, natural fibers can be used as substitute for inorganic fillers. One that can be developed is sisal. Purpose: This study aimed to determine the effects of nanosisal filler volume on compressive strength of composite resin. Methods: In this study, composite resins with nano-sized sisal as filler were manufactured and labeled as nanosisal composites. This research processed sisal fibers into nano size

Abstract:

Staining and subsurface degradation of dental composites were studied in a clinical trial and associated laboratory experiments. The materials in the clinical trial were Clearfil Posterior, Occlusin, and P-30. A significantly higher proportion of Occlusin restorations exhibited marginal stain. An in vitro study indicated that the clinical practice of curing the unfilled bonding resin prior to placing the composite caused the formation of a resin interface with the potential to stain. Bonding resins containing hydrophilic monomers such as HEMA stained more than resins based on BIS-GMA/TEGDMA. I

Abstract:

Resin-based composites are common and widely used materials in dentistry in direct and indirect applications. Their mechanical properties depend on the composition and homogeneity of the resulting structure. This study aims to optimize the mixing process to obtain the most homogeneous mixture possible, which will allow for the better mechanical properties of the composite. A mixture of bis-GMA/UDMA/HEMA/TEGDMA monomers forming a polymer matrix was filled with silanized silica (45 wt%) using different mixing methods.

Abstract:

Composite resin materials for dental restorations are preferred to amalgams for aesthetic reasons, for instance when used in fillings visible on the front teeth. However, the roughness of the filling surfaces is of concern, both for aesthetic and health reasons: the rougher the surface, the greater the accumulation of plaque. The smoothest obtainable surface is produced by allowing the composite to set against a matrix band. However, most restorations require some finishing, and the response of these materials to various polishing techniques is of concern.This study compares surface roughness
