内容記述 |
For the purpose of searching the origin of crystals in the dentinal tubules, firstly, the coronal sclerosed dentin of upper right incisor, obtained from a 75-year-old male, was observed by a scanning electron microscope and an electron probe microanalyser with energy dispersive x-ray spectroscopy. Results were as follows: 1. The attrition surface was covered by a layer of smooth homogeneous deposits in about 8μ thick. 2. The intratubular structures were able to divided into crystals and fibers. 3. The crystals began to appear in the dentinal tubules from 30μ underneath the worn surface. No defferences of number and form of crystals were observed among the regions of dentinal tubules from underneath to near irritation dentin. 4. The intratubular crystals were classified into the following 10 types: rhombohedral, complex type, pyramid faces, step-like, plate-like, cuboidal, roundish edge, prismatic, minute granular and rod-shaped crystal. 5. The fibers within the dentinal tubules were collagen and odontoblast processes, and were both involved in calcium deposition. The former was mostly observed in the region between 0.75 and 1.60 mm from the attrition surface. 6. The surface layer of homogeneous deposits on the worn dentin contained the elements of Al, Si, P, S and Ca, while the subsurface of them only the ones of Mg, P and Ca. 7. The amount of Mg was highest in the intratubular deposits, middle in the peritubular matrix and lowest in the intertubular matrix. |
