The junction between human primary dentine and regular and irregular secondary dentine was examined with a number of different light and electron microscopic techniques. In decalcified material, a narrow band along the innermost surface of the primar

Tubular structures interpreted as being odontoblast processes can be observed with the scanning electron microscope (SEM) on fractured dentin surfaces which have been demineralized and treated with collagenase. To confirm the nature of these structur

Unaltered mature enamel and partially demineralized mature enamel from the cervical third of human permanent teeth were examined by means of transmission electron microscopy, microradiography, phase contrast and Nomarski differential interference mic

To determine the prism sheath configurations in human cuspal enamel 80 teeth were initially ground to produce flat surfaces through the following planes: a horizontal series at successively greater distances from the dentinoenamel junction and longit

Thin ground sections (4–10 μ) of rat incisor enamel were prepared in appropriate planes using a modified hand grinding technique. Phase microscopic observations of these sections confirmed the previously defined rod arrangement in the inner layer

Previous investigators have reported a number of methods which will differentially stain peritubular matrix in undecalcified ground sections of human dentin. The methods, however, were all carried out at pH values which were potentially high enough t

Microradiograms of thin ground sections of transversely cut dentinal tubules were compared to the light microscopic images of the ground sections. The bright rings seen around tubules viewed by ordinary transmitted light with the objective focused on

SUMMARY We have developed a method utilizing relatively thick ground sections of plastic embedded tissue which affords the resolution obtained with 0·5 μm cut sections. The sections, which are permanently affixed to plastic microscope slides, are m

Both mature and developing human enamel were studied by correlative light and electron microscopic techniques. Ordinary light microscopic observations of routinely prepared ground sections produced a totally inaccurate impression of enamel prism dire
