[Light and scanning electron microscopic studies of structure of dentin interglobular spaces (author's transl)].

The author, after giving a literature survey, reports the results of scanning electron microscope examinations of interglobular spaces. The interglobular spaces are mineral-free regions within the dentin. They contain an organic matrix with a smaller amount of ground substance and a smaller number of collagenic fibrils than are contained in the matrix of mineralized dentin. Obviously, hollow spaces observed during microscopic examination are artifacts produced by shrinkage of the matrix despite good fixation. It has not so far been possible to obtain any indications of liquid-filled spaces.

[Eruption and shedding of the teeth in the beaver, Castor fiber albicus (author's transl)].

46 skulls of Castor fiber albicus aged from 0 to 2 years were studied morphologically and radiographically with regard to eruption and shedding of the teeth. According to the characteristics of the dentition the age of immature beavers until to 1 1/2 years can be determined with an error of about 4 weeks. Later the development of the roots and the apposition of cementum are to consider additionally.
