starts at – right right angle from pulpal surface.
Ends at DEJ & CEJ –
ü Dentinal tubules at riit tips and incisal edges – almost straight.
ü Dentinogenesis first begins at – cusp tips .
Length – increases about – 40
Width – constant about – 7 µm.
ü Increment of dental matrix
Until the crown is formed and
teeth erupt and move into occlusion – 4 µm/day.
After teeth eruption – 1 µm/day
Reparative dentin formation
rate – 4 µm/day .
ü Each increment of predentin will be formed along – pulpal border.
ü Fibers that have been described as initial dentin deposition along
the cusp tips – Korff’s fibers.
ü Tomes granular layer increases in amount from –cemento-enamel
junction to root apex.
