The Effect of Simulated Chewing on the Surface Roughness of Direct and Indirect Resin-Composites Opposed by Zirconia: An In Vitro Study

Table 3

Amplitude parameters used in the study to assess surface roughness.

Parameters	Description
	Arithmetic mean deviation within the sample surface area
	Root mean square deviation within the sample surface area
	Maximum peak height or the maximum height of the profile above the mean line within the assessment surface area
	Maximum valley depth or the maximum depth of the valley below the mean line within the assessment area
