Figure 1. Calcium and inorganic phosphate levels in supragingival plaque after treatment with unstabilized calcium phosphate and CPP-ACP mouthrinses [data presented as mean ± SD (n = 30)]. (a,e,f) Ca values significantly different (p < 0.05) from other Ca values not similarly marked. (b,c,d) Pi values significantly different (p < 0.05) from other Pi values not similarly marked, as shown by a one-way classification ANOVA with a post hoc Scheffé test.
