Table 2.

Mean ± standard deviation or median (interquartile range) of fluoride content in blood plasma and different tissues for the treatment groups (n = 16).

Treatments	Blood plasma [F] (µg/mL, ppm)	Kidney [F] (µg/g)	Intestine [F] (µg/g)	Stomach [F] (µg/g)	Liver [F] (µg/g)
TiF₄ varnish	0.038 ± 0.014^a	0.073 (0.018)^a	0.014 (0.005)^a	0.302 ± 0.192ª	0.036 (0.016)^b
NaF varnish	0.030 ± 0.011^a	0.102 (0.068)^a	0.016 (0.011)^a	0.260 ± 0.229ª	0.029 (0.008)^ab
Placebo varnish	0.035 ± 0.015ª	0.069 (0.024)^a	0.017 (0.006)^a	0.260 ± 0.166ª	0.025 (0.010)^a

* Different lowercase letters in the same column indicate that there was a significant difference (n = 16). Blood Plasma: ANOVA, p = 0.2252. Kidney: Kruskal-Wallis, p = 0.0684. Intestine: Kruskal-Wallis, p = 0.3300. Stomach: ANOVA, p = 0.8056. Liver: Kruskal-Wallis, p = 0.0145 (Placebo x NaF, p = 0.1922; Placebo x TiF₄, p = 0.0126 and NaF x TiF₄, p = 0.9606).
