dentin Flashcards
dentin formation begins when in development and by what
early in bell stage - develops from tooth apex down slopes of cusps : coronal dentin (root dentin later)
dentinogenesis
by odontoblasts (cells) that differentiate from ectomesenchymal cells from the dental papilla (odontogenesis)
Dentin phospoprotein (DPP)
most acidic non - collagenous protein and is Ca2+ binding.
these NCP’s are regulating dentin mineralization and secreted by the odontoblast processes
intermediate dentin aka
peritubular dentin
why can caries progress faster in dentin?
half the mineral as enamel and twixe the carbonate and fraction of crystallite size
calcium deficient / carbonate -rich defective apetite
NOT PURE HAP
highly soluble in acids
interglobular dentin
just beneath the mantle dentin where
DSPP mutations cause which diseases?
DD-II, DGI-II and DGI-III
