Adhesion of Hydroxyapatite Nanoparticles to Dental Materials under Oral Conditions

TEM micrograph at 30,000-fold magnification revealing the presence of the 30 min pellicle on enamel sample rinsed with HAP II solution. The pellicle manifests itself as continuous electron-dense layer. The enamel was dissolved due to demineralization of the specimens and thus is no more visible in the TEM figure.
