Invitro evaluation of new treatment for dentin hypersensitivity using BioMin F and BioMin C

Journal of Non-Crystalline Solids, 2023
The present paper aimed at testing BioMin C and BioMin F for treating dentin hypersensitivity (DH). Dentin flat surfaces were treated with EDTA (C10H16N2O8). BioMin C and BioMin F pastes were applied on all specimens followed by exposure of the specimen to an acid challenge. The percentages of coverage by the bioactive materials for the dentin surfaces

Metal resistance or tolerance? Acidophiles confront high metal loads via both abiotic and biotic mechanisms

Frontiers in Microbiology, 2014
All metals are toxic at high concentrations and consequently their intracellular concentrations must be regulated. Acidophilic microorganisms have an optimum growth pH < 3 and proliferate in natural and anthropogenic low pH environments. Some acidophiles
