A small amount of mineral deposits were observed on a thin pellicle containing a few bacteria. High-resolution transmission electron microscopy (HRTEM) and selected-area electron diffraction (SAED) revealed that plate-like crystals were composed of whitlockite and amorphous deposits consisted of an aggregation of fine hydroxyapatite (OH-AP) crystallites. These findings indicate that the present observed deposits are on a free-floating condition without relation to the enamel surface, and that whitlockite and OH-AP can exist independently and stably in vivo. © 1996 Oxford University Press Letters nationallicence high-resolution image nationallicence electron diffraction nationallicence mineral deposit nationallicence whitlockite nationallicence hydroxyapatite nationallicence Microscopy Oxford University Press 45/6(1996-12), 501-504 0022-0744 45:6<501 1996 45 jmicro https://doi.org/10.1093/oxfordjournals.jmicro.a023475 text/html Onlinezugriff via DOI 1 article jats NATIONALLICENCE 856 40 https://doi.org/10.1093/oxfordjournals.jmicro.a023475 text/html Onlinezugriff via DOI NATIONALLICENCE 100 1- Hayashi Yoshihiko Department of Endodonitics and Operative Dentistry, Nagasaki University School of Dentistry, 1-7-1 Sakamoto, Nagasaki, 852 Japan NATIONALLICENCE 773 0- Microscopy Oxford University Press 45/6(1996-12), 501-504 0022-0744 45:6<501 1996 45 jmicro Metadata rights reserved CC BY-NC-4.0 http://creativecommons.org/licenses/by-nc/4.0 nationallicence BK010053 XK010053 XK010000 NATIONALLICENCE NATIONALLICENCE NL-oxford
