Fabrications of zinc-releasing biocement combining zinc calcium phosphate to calcium phosphate cement

Journal of the Mechanical Behavior of Biomedical Materials, 2014
Recently, zinc-releasing bioceramics have been the focus of much attention owing to their bone-forming ability. Thus, some types of zinc-containing calcium phosphate (e.g., zinc-doped tricalcium phosphate and zinc-substituted hydroxyapatite) are examined and their osteoblastic cell responses determined.

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.

Comparison between a zinc phosphate cement and a glass ionomer cement for cementation of orthodontic bands

The European Journal of Orthodontics, 1983
The relative merits of zinc phosphate cement and glass ionomer cement for cementation of orthodontic bands are investigated in a controlled clinial trial. The good manipulative characteristics, relatively high compressive strength, convenient setting time and easy removal of excess cement, make zinc phosphate cement preferable for routine cementation ...

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

Effects of Zinc and Strontium Doping on In Vitro Osteogenesis and Angiogenesis of Calcium Silicate/Calcium Phosphate Cement.

ACS Biomaterials Science & Engineering, 2023
Based on multiple biological functions (mainly osteogenesis and angiogenesis) of bioactive ions, Zn/Sr-doped calcium silicate/calcium phosphate cements (Zn/Sr-CS/CPCs, including 10Zn-CS/CPC, 20Sr-CS/CPC, and 10Zn/20Sr-CS/CPC) were prepared by the ...
