The mean reduction in pH was 1.1 for the samples stored at room temperature for 3 months and 0.8 for the refrigerated samples. Conclusion: This in vitro study showed that the expected concentration of sodium hypochlorite solution made of household bleach for endodontic purposes is different from ...
This solution was prepared by dissolving 56 mg of crystalline H3PO4 per 1 L of deionized water. Since this would make an unnaturally acidic solution, the pH was raised back to 7.0 through addition of a few drops of 6 N sodium hydroxide (NaOH) solution. The final pH-balanced solution ...
Thus, in agreement with traditional perspectives [31,95], it is clear that the pH of the diagenetic environment constitutes an overarching control on bone fossilization—not only at the ultrastructural level, but also the molecular level. Despite constant immersion under oxic conditions, the femur ...
