Table 2. Comparison among groups based on change in gloss between pre and post thermocycling.

*statistically significant value of p < 0.05; SD = standard deviation, SE = standard error, CI = confidence Interval.

P-value was derived from a one-way analysis of variance (ANOVA) test.

Gloss test: Pre thermocycling

Gloss test: Post thermocycling
