Table 2.

Relative number of dentine tubules with reference to young deep peripheral dentine adjusted for field of view.

Location	Relative number of dentine tubules (95% CI)
Location	Young	Mature
Shallow Central	1.61 (0.90, 2.88)^AB	1.71 (1.10, 2.66)^ABC
Shallow Peripheral	1.05 (0.64, 1.71)^AB	1.21 (0.93, 1.57)^AB
Deep Central	2.50 (1.61, 3.87)^CD	2.96 (2.31, 3.80)^D
Deep Peripheral	1.00 (Reference)^A	1.57 (1.10, 2.25)^BC

*Margins sharing a letter show values are not significantly different at a type one error rate of 0.05 while controlling for the field of view.

Model: P-value (Location) < 0.001; P-value (Age) = 0.013; P-value (Location*Age) = 0.68; Model R-square = 0.09.
