Retention of cast posts cemented with zinc phosphate cement using different cementing techniques

Journal of Prosthodontics, 2001
Purpose This study compares the effect of different cementation techniques on the retention of cast posts and cores.Materials and Methods Twenty‐four extracted single rooted human teeth were used in this study. After routine preparation of the root canals, the canal space was enlarged with reamers.

In vitro toxicity tests of zinc phosphate cement

Journal of Oral Rehabilitation, 1978
SummaryBHK‐21 (C‐13) cells were exposed to freshly mixed zinc phosphate cement for 0·5, 1 and 2 h in a simulated cavity apparatus. The effect on the cells was evaluated by quantitative measurement of acid phosphatase and succinic dehydrogenase reaction product in order to determine organelle membrane permeability. After 0·5 h cellmaterial contact there

Elements in minor or trace quantities in zinc phosphate cements

European Journal of Oral Sciences, 1979
Abstract – Eight powders and two liquids of zinc phosphate cements have been analyzed by optical emission spectrography for the purpose of characterizing elements in minor or trace quantities. The following elements were measured: bismuth, boron, cadmium, chromium, copper, iron, lead, silver and titanium.

[Fatigue of dental zinc phosphate cement].

Shika zairyo, kikai = Journal of the Japanese Society for Dental Materials and Devices, 1992
The fatigue characteristics of a zinc phosphate cement were examined. Using a split mould made of stainless steel, 12 mm x phi 6 mm column shape specimens were prepared. Fatigue tests were done by loading partially repeated pulsating diametrical tensile stress of 1-20 Hz, minimum stress was 0.2 MPa (2.0 kgf/cm2) and maximum stress was 3.5-5.4 MPa (36 ...
