BACKGROUND AND OBJECTIVES Acrylic resin ruled the dental profession for 60 years, and this success is attributed to its aesthetics, handling properties, physical and biological compatibility, its stability in oral environment and its cost effectiveness. The objective of this study is to evaluate and compare the bond strength of acrylic resin teeth treated with various conditioning materials lik...

An orthopaedic surgeon developed dermatitis from acrylic materials. The acrylic monomer was found to penetrate surgical rubber gloves readily. Cases of "rubber glove dermatitis" with negative patch tests may have a similar explanation. Laboratory tests suggest that monomer does not damage rubber sufficiently to allow bacteria to penetrate gloves, but it remains possible that this would happen u...

Doubly curved nanofiber-reinforced optically transparent composites with low thermal expansion of 15 ppm/k are prepared by hot pressing vacuum-filtered Pickering emulsions of hydrophobic acrylic resin monomer, hydrophilic chitin nanofibers and water. The coalescence of acrylic monomer droplets in the emulsion is prevented by the chitin nanofibers network. This transparent composite has 3D shape...

AA and its esters are unlikely to persist in the environment. Acrylates have medium to high mobility for adsorption and desorption to soils. They are not expected to bind to soil or sediment. If released to air, they will undergo photo-degradation within days. AA and all of the esters are readily biodegradable except t-BA, which is inherently biodegradable. In contact with water, abiotic hydrol...

Background: After polymerization process, heat cured acrylic resin denture base actually still contains residual monomers that can become potential irritants later in oral cavity. Polymerization process is essential to obtain acrylic resin which can meet the requirements of the biocompatible and good physical properties. To meet the requirements, there are several methods of polymerization proc...

Objectives: This In-vitro study was designed to compare the Impact strength and Residual monomer content of conventional and high impact types of denture base resins polymerized by Compression and Injection molding technique with short curing cycle. Materials and Methods: Forty samples were made (twenty from each technique)in the dimension of 60 × 10 × 3 with 2 mm notch on the thickness side. T...

PURPOSE The aim of this study was to clarify the effect of addition of glass fibers and titanium dioxide nanoparticles to the conventional acrylic resin. The tested parameters were monomer release, deflection at fracture, flexural strength, flexural modulus, and toughness. The modified acrylic resin groups were compared to the conventional unmodified and high impact types. The correlation betwe...
