Table 2 One-way ANOVA (Kruskal-Wallis rank test) results for average surface roughness observed in zirconia between 3 different finishing/polishing systems at 3 different autoclaving cycles (1, 5, 10).

Gp – group; N – number of specimens; IQR – interquartile range; H – difference between 2 or more groups of an independent variable on a continuous dependent variable; – probability value; MRS – mean rank score; E – EVE Diacera polishing kit; U – Ultradent Jiffy polishing kit; W – SS White polishing kit. Numbers 1, 5 and 10 represent the number of autoclave cycles performed on the finishing polishing kit. Statistical interpretation: The test employed a one-way ANOVA on ranks (Kruskal-Wallis H test); ^* significant at
