ü  Methods of removal of inorganic constituents – decalcification.

ü  Methods of removal of organic constituents- incineration/ organic chelation .

ü  Excess of calcium in the dentinal tubules is referred to as – sclerotic dentin.

ü  First convexity of doubly curved dentinal tubules is directed towards- apex.

ü  S shaped dentinal tubules.

i.                      starts at – right  right angle from pulpal surface.

ii.                   Ends at DEJ & CEJ – perpendicularly.

ü  Dentinal tubules at riit tips and incisal edges – almost straight.

ü  Dentinogenesis first begins at – cusp tips .

ü  Odontoblasts.

i.                     Length – increases about – 40 µm.

ii.                    Width – constant about – 7 µm.

ü  Increment of dental matrix

i.                     Until the crown is formed and teeth erupt and move into occlusion – 4 µm/day.

ii.                    After teeth eruption - 1 µm/day .

iii.                  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.
