“…Some authors fixed by immersion in glutaraldehyde or glutaraldehyde-formaldehyde mixture (Garant and Nalbandian, 1968;Matthiessen and Bulow, 1969;Lester, 1970;Katchburian and Holt, 1972;Decker, 1973;Slavkin et al, 1976). Only a few studies used teeth fixed by whole body perfusion (Jessen, 1968;Kallenbach, 1971Kallenbach, , 1973Kallenbach, , 1976Kallenbach, , 1977.…”

“…The first is via classical exocytosis, whereby the membrane of secretory granules fuses with surface cell membrane (Frank and Nalbandian, 1967;Reith, 1967;Matthiessen and Bulow, 1969;Frank, 1979) or fuses to deep membrane infoldings (Kallenbach, 1977;Simmelink, 1982). The second involves a tubular network interconnecting many granules (Smith, 1979), thereby making the simultaneous release of the content of many granules possible.…”

“…Although the relationship between growth areas and Tomes' process has not been well established, it is known that both rod and interrod growth sites are associated with infolded membrane (Warshawsky et al, 1981), and secretory granules often accumulate adjacent to these infoldings (Weinstock and Leblond, 1971). Granules fused to surface membranes have occasionally been observed at the rod growth site (Reith, 1967;Frank and Nalbandian, 1967;Matthiessen and Bulow, 1969;Frank, 1979) but not at the interrod growth sites where few secretory granules have been observed (Weinstock and Leblond, 1971;Kallenbach, 1973). Alternatively, it has been postulated that secretory granules fuse to an internal tubular network (Smith, 1979) or to deep membrane invaginations (Kallenbach, 1977;Simmelink, 1982).…”

“…One is the material located between the distal ends of the secretory ameloblasts and the mineralization front (36). It has been observed in this location in developing enamel of many different species (2,4,5,8,15,16,17,21,34,39) and also in enamel formed in vitro (37). It is generally described as a stippled or finely granular material.…”

“…In fully mature rat and human enamel, the crystals have filled in most of the space originally available between the thin ribbonshaped crystals. Only a narrow space, [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25] A in width, separates individual crystals (20,26).…”
