TABLE 6.

Microhardness of trabecular and cortical bone in vertebral bodies (VB), and of cortical bone in distal femurs in each treatment group.

	Fluoride Treatment (ppm)	Strain A/J	Strain SWR/J	Strain 129P3/J

VB microhardness for trabecular bone	0	27.6 ± 2.1	25.1 ± 2.5	25.9 ± 1.7

	100	24.5 ± 2.4	24.8 ± 3.2	25.6 ± 1.7

VB microhardness for cortical bone	0	31.1 ± 2.0	30.3 ± 0.9	31.7 ±1.7

	100	31.4 ± 3.1	30.6 ± 1.6	31.4 ± 1.3

Distal femur cortex microhardness	0	39.4 ± 1.5	36.8 ± 2.3	37.9 ± 2.6

	100	38.0 ± 2.5	35.3 ± 1.0	37.5 ± 1.7

Data are presented as means ± SD. No statistical difference was noted for the microhardness of cortical and trabecular bone in the three strains.
