Results The results were subjected for appropriate statistical analysis; Kruskal–Wallis test revealed that intergroup comparison of the mean percentage of tubule occlusion was statistically 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 B and D which was not significant [ Table 2 and Figure 1 ].
