Mechanical manipulation of silicate cements [PDF]
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.

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.

The durability of silicate cements may be related to the porous nature of the spatulated mix. Vacuum mixing eliminates porosity, but the effect of the elimination of this porous nature on other properties of silicate cements has not been determined.

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).

Silicate cement in a cell culture system
European Journal of Oral Sciences, 1973abstract— Human epithelial cells (NCTG 2544) were grown as monolayer cultures in the presence of silicate cement disks (Bio‐trey 9®). A cytotoxic effect was found on the surface of the disks after 24 h, whereas a corresponding effect was obvious around the disks after incubation for 3 d.

Nanostructure of Calcium Silicate Hydrates in Cements
Physical Review Letters, 2010Calcium silicate hydrate (CSH) is the major volume phase in the matrix of Portland cement concrete. Total x-ray scattering measurements with synchrotron x rays on synthetic CSH(I) shows nanocrystalline ordering with a particle diameter of 3.5(5) nm, similar to a size-broadened 1.1 nm tobermorite crystal structure.

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.

The in vivo dissolution of tricalcium silicate bone cement
Journal of Biomedical Materials Research Part A, 2021AbstractThis study aimed to investigate the in vivo dissolution of tricalcium silicate (Ca3SiO5, C3S) bone cement in the rabbit femoral defect. Results indicated that C3S paste directly integrated with the bone tissue without the protection of the bone‐like apatite.
