On ultrathin sections of developing dentine and other hard tissues we have observed primary apatitic chains (strands) composed of nanometer-sized islands (dots). By energy-filtering selected area electron diffraction patterns (SAED) in the ZeissEM902

A locally enhanced element concentration influences the result of an X-ray microanalysis at a neighbouring position. This influence was investigated for the first time systematically in organic (biological) material using sections of epoxy resin (thi

The biogenetic formation of mineral crystals, one aspect of biomineralization, is a multistep process of apatite formation throughout the growth of dentin tissue. An important step is the transformation of the non-mineralized predentin matrix to mine

Morphological and structural analysis of the earliest stage of crystal formation in enamel of rat incisors, by use of energy filtering transmission electron microscopy (EFTEM), has shown needlelike crystallites with a dotlike substructure. We conclud

Collagen is the dominant fibrous protein not only in connective tissues but also in hard tissues, bone, dentin, cementum, and even the mineralizing cartilage of the epiphyseal growth plate. It comprises about 80-90% (by weight) of the organic substan

The primary crystallites of the different developing hard tissues have an apatite structure. However, they have crystal lattice distortions representing an intermediate state between amorphous and fully crystalline. We have applied energy-filtering t

We have found, at high EM magnification, on ultrathin sections of shock-frozen, freeze-dried, embedded pieces of the developing hard tissues, that the primary crystallites consist of strands composed of nanometer-sized apatitic islands, which rapidly

Primary crystal formations in all hard tissues are, according to our investigations, Ca-phosphate chains composed of nanometer sized particles (dots) which develop along the matrix macromolecules. In circumpulpal dentine the centre-to-centre distance

The purpose of this study was to compare the biomineralization of circumpulpal dentine with that of mantle dentine by ultrastructural and element-analytical techniques. Forty upper second molar germs of 10-day-old albino rats were cryofixed in liquid
