Pulp biology Flashcards
cell layers in the pulp
pulp core
cell rich zone
cell-free zone of Weil
odontoblast layer
what type of cells are odontoblasts
post-mitotic cells
odontoblast role
dentine formation
what replaces odontoblasts to become 2nd gen odontoblasts to form reparative 3ry dentine
Hoehl’s cells
fibroblast role
synthesise and secrete collagen and non-collagenous proteins
what type of cells are pulpal inflammatory cells
pulpal dendritic cells
macrophages
histocytes
lymphocytes
what makes up the ECM
collagen
phosphorylates ECM proteins
non-phosphorylated ECM proteins
proteoglycans
GFs
enzymes
what GFs are in the ECM
bmp
tgfB receptors
what types of nerves are mainly in pulp
sensory afferent
what innervates the cell free zone
plexus of raschkow
what cells form odontoblast like cells
DPSC
what cells can form bone or dentine and have a high proliferation rate
SHED cells
when are growth factors released
acidic environment - caries
what type of dentine is produced with a mild stimulus
reactionary
what type of tertiary dentine is formed with a strong stimulus
reparative dentine
