Comparison of the microstructure of crown and root dentin by a scanning electron microscopic study

open access: yesJournal of Dental Sciences, 2010
Detailed information of the dentin microstructure is essential in order to interpret data from investigations on dentin adhesive materials. Most studies of dentin microstructure focused on the crown dentin, and few compared microstructures of the crown ...

Odontoameloblastoma with extensive chondroid matrix deposition in a guinea pig [PDF]

open access: yes, 2018
Odontoameloblastomas (previously incorporated within ameloblastic odontomas) are matrix-producing odontogenic mixed tumors and are closely related in histologic appearance to the 2 other types of matrix-producing odontogenic mixed tumors: odontomas and ...

Dentin sialoprotein and dentin phosphoprotein have distinct roles in dentin mineralization [PDF]

open access: yesMatrix Biology, 2009
Dentin sialophosphoprotein (DSPP), a major non-collagenous matrix protein of odontoblasts, is proteolytically cleaved into dentin sialoprotein (DSP) and dentin phosphoprotein (DPP). Our previous studies revealed that DSPP null mice display a phenotype similar to human autosomal dominant dentinogenesis imperfecta, in which teeth have widened predentin ...
