Because of published reports describing phosvitin's affinity for calcium and potential antibiotic activity, this study was undertaken in order to evaluate phosvitin for both antibiotic activity against common microorganisms and the ability to protect hydroxyapatite surfaces from acid damage. To more clearly define its antibiotic action, the effects of phosvitin on <i>Micrococcus luteus</i>, <i>P. mirabilis</i>, <i>B. cereus</i>, <i>E. coli</i>, and <i>S. epidermidis</i> were evaluated. In both Kirby-Bauer tests and liquid culture growth inhibition assays, phosvitin inhibited <i>M. luteus</i>, a microorganism that thrives in the human mouth, but not the other bacteria tested. The MIC of phosvitin was determined to be 31.3 <i>μ</i>g/mL when delivered in 1 mM CaCl₂ but was 0.5 mg/mL in the absence of added calcium. Expanding on the potential impacts of phosvitin on the mouth, its action was evaluated in a model of tooth decay represented by acid-damaged hydroxyapatite discs.

To compare the conventional method used in decalcification with the microwave method using different decalcification solutions.
