Further electron microscope studies of dentine

摘要: Abstract 1. Further electron microscope studies of dentine are reported. 2. By the use various reagents, several distinct structural layers identifiable in odontoblast process. These are: (a) a central core, apparently labile protein nature; (b) thin organic sheath immediately surrounding this core; (c) thicker composed material having some properties myelin; and (d) an outer fine fibrils, which appear collagenous. 3. The similarity between these those nerve fiber is discussed, with reservation that such does not necessarily constitute identity. 4. process surrounded by thick, highly calcified tubular wall. This wall crossed fibrillar trabeculae extend beyond its confines to unite on one side fibrils intertubular matrix other. 5. separated from further collagenous sheath. run helical paths around thus almost invisible transverse section. Other transversely continuous hand and, through sheath, 6. need for new descriptive terminology dentinal structure discussed suggestions made light recent knowledge.
