Quantitative determination of type A and type B carbonate in human deciduous and permanent enamel by means of Fourier transform infrared spectrometry. -

The difference in carbonate content between deciduous and permanent enamel may be one of several factors contributing to faster caries progression in deciduous teeth.

The swelling phenomenon of acrylic resin polymer teeth at the interface with denture base polymers. -

Results suggest that by increasing the polymerization temperature, the monomers of the denture base polymers diffused more effectively into acrylic resin polymer teeth. This increases the bond strength between the polymer teeth and the denture base polymer.

How different curing methods affect mechanical properties of composites for inlays when tested in dry and wet conditions. -

This investigation was to evaluate the differences in the mechanical properties of 3 composite materials in relationship to the intraoral and extraoral curing techniques of direct and indirect (inlay) restorations, and how the mechanical properties are affected by water sorption

Swelling of poly(methyl methacrylate) resin at the repair joint -

The study suggests that methyl methacrylate diffuses more easily into an autopolymerized poly(methyl methacrylate) than into heat-activated poly(methyl methacrylate) during the repair of denture base polymer.

The effects of polymerization temperature on the acrylic resin denture base-tooth bond -

The effect of different polymerization temperatures on the bond strength and the type of bond failure between denture base polymers and polymer teeth were investigated using two autopolymerized and one heat-polymerized denture base material.

Evidence for induction of cardiorespiratory and vascular complications by methylmethacrylate monomer in hip replacement surgery. Laboratory and animal investigations -

In vitro and in vivo studies have shown that MMA in different ways contribute to activation of coagulation. In addition, MMA per se is cytotoxic and may in clinically relevant concentrations cause disintegration of vascular and blood cells with potential release of proteolytic enzymes and exposure of subendothelial constituents.
