Comparative Analysis of CPP-ACP, Tricalcium Phosphate, and Hydroxyapatite on Assessment of Dentinal Tubule Occlusion on Primary Enamel Using SEM: An <i>In Vitro</i> Study.

RESULTS The results were subjected for appropriate statistical analysis; the Kruskall–Wallis test revealed that an intergroup comparison of the mean percentage of tubule occlusion was highly significant ( p value < 0.001) ( Table 1 ) and Mann–Whitney U test showed that the tubule occlusion potential was statistically significant among all groups except for Group II and IV, which was not significant ( Table 2 and Fig. 1 ).
