@article{oai:mdu.repo.nii.ac.jp:00000503, author = {佐原, 紀行}, issue = {3}, journal = {松本歯学}, month = {Dec}, note = {application/pdf, The resorption and shedding of the human deciduous teeth are physiological processes associated with the replacement of permanent teeth. Numerous studies have been reported the tissue changes which occur during physiological root resorption of the human deciduous teeth, however, to date, the precise mechanism of this resorptive process is not fully understood. Especially, there is little information about how root resorption is initiated, and how the final shedding of tooth is regulated. In this review, firstly, we introduce the phenomenon of the odontoclastic resorption at the pulpal surface of coronal dentin prior to the shedding of human deciduous teeth. Secondly, the cytodifferentiation of human odontoclasts is described with special attention has been paid to the morphology and function. We also demonstrate cellular/extracellular events during the tooth resorption-repair process in this internal resorption. Finally, a possible mechanism of exfoliation of human deciduous teeth is discussed.}, pages = {213--229}, title = {ヒト乳歯の吸収と脱落}, volume = {31}, year = {2005} }
