Paper Title:
Morphological and Dimensional Characteristics of Bone Mineral Crystals

In this work, Scanning Electron Microscopy (SEM) has been used to determine the size and morphology of bone mineral crystals obtained from hydrazine-deproteinated parietal bone and femur of Wistar rats aged 15 days, 1 month and 1 year. Apart from the Scanning Electron Microscopy study, crystal size was also determined by X-ray diffractometry, using the Debye- Scherrer equation. Analyzing the results obtained and those reported in the literature for isolated crystals, it is possible to evaluate the influence of age and type of bone on the nanostructure of bone mineral and also propose the existence of a fundamental morphological unit that repeats itself in bone mineral formation.
