Figure 3. Effects of diet texture and composition on dentin apposition in molars of growing rats (A) and their terminal salivary gland and body weight (B). Twenty-one-day-old rats were maintained for 5 wks on standard rat diet (Std diet) or on a high-sucrose diet (HSD), and each diet was presented in the form of either pellet or powder. The results for each treatment group are expressed as the mean ± SEM. Statistical difference between treatment means was assessed by ANOVA, followed by the Bonferroni post hoc test. Significant differences resulting from either the effect of diet texture (pellet vs. powder) or diet composition are indicated by double-headed arrows.
