Mechanical manipulation of silicate cements

The Journal of the American Dental Association, 1955
adapts to dentistry a suction or vacuum principle first used in industry. It pro­ vides a means of cleansing the operating field with copious isothermal irrigation. The debris is then removed by a power­ ful but nevertheless a gentle vacuum air stream. Human tissues are maintained in their natural wet state.

Toxic elements in silicate cements

European Journal of Oral Sciences, 1979
Abstract – Six brands of silicate cements have been characterized by means of optical emission spectrography with respect to the contents of elements in minor or trace quantities in a search for presence of possible toxic elements. Beryllium was observed in two powders at levels of 1.3 and 1.6%. Cadmium was found in two powders at levels of 0.02 and 0.

Dental Silicate Cements: V. Electrical Conductivity

Journal of Dental Research, 1968
The variation of the electrical conductivity of dental silicate cements with age is described, and the effects of varying temperature, powder-liquid ratio, and constitution of the liquid are discussed. A correlation with specification solubility is shown for a number of commercial brands.

Dental Silicate Cements: VI. Infrared Studies

Journal of Dental Research, 1968
Infrared studies have shown that silica gel and H2PO4-1 ions are formed in fresh cement paste. Subsequently, during setting and hardening, H 2PO4-1 ions further react to form covalent phosphates and are removed from the system. In an uncertified cement, H2PO 4-1 ions were found in substantial amounts even in the set cement, which accounted for poor ...

Dental Silicate Cements: VII. Alternative Liquid Cement Formers

Journal of Dental Research, 1968
A number of alternative liquids to orthophosphoric acid have been examined as possible cement formers. Significant rules have been established for the chemical composition of cement-forming liquids. Cementation could only be achieved with aqueous solutions of certain complexing acids: polycarboxylic, ketonic, and fluoboric acid and derivatives of ...
