Bond strength between dentine and a novel fast-setting calcium silicate cement with fluoride.
European Journal of Oral Sciences, 2019The aim of this study was to evaluate the dentine bond strength of a novel fast-setting calcium silicate cement (Protooth) versus a calcium hydroxide-based cement (Dycal), a calcium silicate cement (ProRoot MTA), and a glass ionomer cement (Ketac-Molar).

Dissolution rates of silicate cements
Biomaterials, 1982The literature relating to the dissolution of the silicate cements is reviewed, including the methodology, intrinsic factors relating to composition and method of mixing, curing etc. and extrinsic factors, i.e. the medium, pH, ionic strength etc. to which the sample of cement is exposed.

Formation of Dental Silicate Cement
Nature, 1970THE setting of dental silicate cement, a material widely used as an anterior tooth filling1, is generally attributed to the formation of silica gel2. Its potentially high strength (< 3,000 kg/cm2) compared with known silica gel cements3 (150–270 kg/cm2) is, however, at variance with this view.

Solubility of a Silicate Cement
Journal of Dental Research, 1970Samples of a silicate cement were soaked in different environments for varying lengths of time. The resulting solutions were analyzed for Na, Zn, Ca, Al, and Si by atomic absorption spectrophotometry. All of the elements showed a decreasing rate of solution with increasing time.

Mechanical manipulation of silicate cements
The Journal of the American Dental Association, 1955adapts 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, 1979Abstract – 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, 1968The 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.
