TABLE 4.

Bone mineral crystal length (002) and bone mineral crystal width (310), estimated by x-ray diffraction.

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

Bone mineral crystal length (Å)	0	147.2 ± 12.1	148.5 ± 5.9	130.4 ± 2.6
	25	140.3 ± 4.4	143.6 ± 9.4	135 ± 6.8
	50	146.7 ± 8.7	144.4 ± 10.6	133.5 ± 6.3
	100	141 ± 3.5	148.4 ± 10.5	133.9 ± 7.0

Bone mineral crystal width (Å)	0	56.2 ± 1.1	55.3 ± 1.4	52.2 ± 1.3
	25	56.2 ± 1.0	56.4 ± 1.1	53.5 ± 1.5
	50	58.5 ± 1.8 ^**	58.4 ± 2.1	54.5 ± 1.0 ^***
	100	59.4 ± 1.1 ^***	61.2 ± 2.2 ^***	56.4 ± 1.0 ^***

Data are presented as means ± SD.

A p value < 0.001 is noted as ***. A 0.001<p<0.05 is noted as ** and a 0.05<p< 0.1 is noted as *.

The fluoride treatment did not significantly affect the crystal length, but it induced a significant increase of the crystal width in all three strains. The crystal length and width were significantly smaller in the strain 129P3/J (p<0.05), compared to the other two strains.
