Micromechanical Property recovery of human carious dentin achieved with colloidal nano β tricalcium phosphate
Journal of Dental Research, 2008Co-Authors: Yo Shibata, Li Hong He, Yu Kataoka, Takashi Miyazaki, M V SwainAbstract:Reconstitution of carious dentin has been recognized as difficult, because it progresses by loss of collagen polymerization and by demineralization under acidic conditions. Recently, colloidal alkaline nano-calcium phosphate, prepared by electrical discharge in a buffered physiological saline solution, has been shown to be effective in the formulation of a bone-like biocomposite by simply being mixed with acidic collagen solution. It was hypothesized that colloidal calcium phosphate was suitable for the reconstitution of carious dentin. Natural caries lesions in dentin from permanent teeth were exposed to colloidal hydroxyapatite and β-tricalcium phosphate for 10 days. The Micromechanical properties of these tissues were evaluated by nano-indentation. The elastic modulus of human carious dentin improved after samples were immersed in colloidal β-tricalcium phosphate. The mineral density of carious dentin exposed to β-tricalcium phosphate increased more than that immersed in hydroxyapatite. However, since ...

A Micromechanical elastic Property study of trabecular bone in the human mandible
Journal of Materials Science: Materials in Medicine, 2007Co-Authors: Tsutomu Nomura, J. Lawrence Katz, Michael P. Powers, Chikara SaitoAbstract:Micromechanical properties of human mandibular trabecular bone, with particular interest to any site differences were investigated. A mandible was harvested from a 66 year-old female cadaver free from bone disease. It was embedded in PMMA, cut into 2mm sections and polished. Micromechanical Property measurements were obtained using the UH3 Scanning Acoustic Microscope (SAM) (Olympus Co., Tokyo, Japan) at 400MHz in the burst mode. 6 vertical slices from the right and 6 horizontal slices from the left were chosen. In each of the 12 samples, 3 points were measured; first in the center, the other 2 from the margins. Data were analyzed statistically by SPSS (SPSS, Inc.) using Student’s t-test. The average value of reflection coefficient r is 0.58±0.079 with the range from 0.46 to 0.64; E =25.0±5.64 GPa. There is no significant difference in properties in the osteonal direction of related cortical bone and those found between the marginal area and center areas. The average value of r from the right side, 0.60±0.07, is statistically higher than the average value of from the left side, 0.56±0.07. Micromechanical properties of both mandibular trabecular and cortical bone have almost the same values.
