Current concepts of the biology of tooth eruption Gorski JP; Marks SC JrCrit Rev Oral Biol Med 1992[]; 3 (3): 185-206Tooth eruption is defined as the movement of a tooth from its site of development within the jaws to its position of function within the oral cavity. We present a critical review of evidence for the mechanisms and regulation of the intraosseous and supraosseous phases of eruption, with an emphasis upon the canine premolar model studied by the authors. Analyses at different stages of premolar eruption indicate that selective fragmentation of dental follicle protein DF-95 correlates with the presence of elevated levels of follicular collagenase and stromelysin, and with the onset of premolar movement. A dramatic decrease in these metalloproteinases followed initiation of movement. A biochemical and cell biological model for regulation of tooth eruption is proposed based upon these new and existing data.|Animals[MESH]|Biology[MESH]|Dental Sac/anatomy & histology/physiology[MESH]|Humans[MESH]|Periodontal Ligament/anatomy & histology/physiology[MESH]|Tooth Eruption/*physiology[MESH] |
