Scanning electron microscopy of rat buccal epithelium on deparaffinized or epon-etched sections provided observations of intracellular structures especially of keratohyaline granules. Cell-walls and nuclei were easily observable and the two types of keratohyaline granules already seen in transmission electron microscopy were identified namely(More)
Scanning electron microscopy was used to examine pulp stones which are small calcified formations found in the coronal and/or radicular part of the dental pulp. Pulp stones range considerably in size and shape. Most are round or oval but others can be irregular and may correspond to a reduced duplicate of the pulp chamber anatomy. Both free and attached(More)
Calcium plays an important role in phenomena relating to permeability and regulation of the extracellular compartments. The diffusion anomalies of sulphur previously observed in the oral epithelium of the hypocalcemic rat could possibly be attributed to a reduction in diffusion of sulphur related to disturbances in cellular renewal. The injection of H3(More)
