Phase equilibrium in Ag-Pd-Cu dental alloys -

A dental alloy consisting of Ag-Pd-Cu-Au has been annealed at various temperatures and subsequently quenched to produce a solid solution before a hardening heat treatment. The phases present were studied by means of X-ray diffraction measurements.

The influence of various admixes on the physical properties of a polycarboxylate cement. -

Aluminum oxide, aluminum hydroxide, aluminum fluoride-trihydrate, and titanium dioxide hydrate were added to a commercial polycarboxylate cement. The first substance increased the setting time and certain physical properties. The others decreased the same properties to varying degrees

Identification of methacrylates and acrylates in dental materials by mass spectrometry -

The electron-impact and methane chemical-ionization mass spectra of selected methacrylate and acrylate monomers commonly used in dental materials are reported and discussed.
