The distribution of magnesium in developing rat incisor dentin.
Previous studies have shown that rat incisor dentin contains a considerable amount of magnesium that is distributed heterogeneously. The cementum-related dentin, especially its incisal portion, is richest in magnesium. It was the purpose of the present study to investigate the changes that occur in the magnesium content during dentin maturation. Cross-sections were prepared from rat incisors at...
متن کاملDistribution and organization of odontoblast processes in human dentin.
The distribution and organization of odontoblast processes in young human dentin was examined with a scanning electron microscope. By applying the HCl-collagenase method, the extracellular matrix of dentin was almost completely removed, thereby exposing the odontoblast processes and their branches to direct observation. The odontoblast processes are located close to the dentinoenamel junction. ...
متن کاملA three-dimensional reconstruction of the rods in rat maxillary incisor enamel.
A three-dimensional reconstruction of the rod profiles seen in inner and outer rat incisor enamel was made from serial 1 μ cross sections of a decalcified upper incisor. The enamel rod was found to be an elongated structure which travelled incisally relative to its origin and ran continuously from the dentino-enamel junction to the enamel surface. The rod was divisible into an inner and outer e...

8 Three-dimensional beach features such as crescentic sandbars and rip channels influence beach 9 response to, and recovery from, storm waves, as well as significantly affecting the safety and 10 amenity provided by the surf-zone for beach water-users. In this contribution temporal variations in 11 subtidal and intertidal beach three-dimensionality are observed at a high-energy macrotidal beach...
متن کاملThe inorganic components of cementum- and enamel-related dentin in the rat incisor.
Recently, we have shown that, in rodent incisors, the crown- and root-analogue dentin (enamel- and cementum-related dentin) show differences in mineralization rates (Beertsen and Niehof, 1986) and composition of the organic matrices (Steinfort et al., 1989). It was the aim of the present study to determine whether these differences were accompanied by differences in the inorganic components. Ra...
