Comparison of Dentin Thickness in wt and DSPP-KO First Molar from Postnatal 1 to 21 Days

Postnatal day	wt Dentin thickness	DSPP-KO dentin thickness
1	No dentin in 3/6 animals	27.44±2.83 μm^a
6	30.11±4.48 μm	46.78±2.39 μm^a
13	85.22±4.76 μm	93.78±20.4 μm N.S.
21	210±40.57 μm	110±22.1 μm^a

Dentin thickness was measured from histological sections stained with hematoxylin and eosin from wt and DSPP KO from postnatal 1–21-day first molars. The dentin thickness from each time point was derived from six samples.

^{^a}

P<0.05 compared with wt dentin thickness.

DSPP, dentin sialophosphoprotein; KO, knockout; N.S., no significant difference; wt, wild-type.
