Table 4.

Effects of treatments on development (sulcal-surface caries and severity) of dental caries in rats (Keyes' score)

	Vehicle control	PAC (1.5 mg/ml)	250 ppm fluoride
Sulcal-surface caries	52.9 (2.l)^a	51.1 (2.6)^a	40.4 (9.5)^b
Sulcal-surface severity
Ds	45.4(1.7)^a	43.4 (2.7)^a	35.2 (8.2)^b
Dm	33.7 (6.5)^a	25.0 (5.8)^b	12.1 (7.2)^c
Dx	24.3 (6.7)^a	17.1 (7.4)^b	5.1 (5.4)^c

Values denote means with SD in parentheses (n = 16). Values followed by the same superscripts are not significantly different from each other (p < 0.05; ANOVA; comparison for all pairs using the Tukey-Kramer HSD).
