Surface Geometry of Four Conventional Nanohybrid Resin-Based Composites and Four Regular Viscosity Bulk Fill Resin-Based Composites after Two-Step Polishing Procedure

Table 3

Qualitative assessment of the materials surfaces in the SEM study. The difference in images assessment between the two researchers was not greater than 10%.

Conventional composite	Spot SEM evaluation of the surface	Descriptive evaluation of the surface	Bulk fill composite	Spot SEM evaluation of the surface	Descriptive evaluation of the surface
	Mean			Mean
TEC	10.5	Smooth surface, no damage	TBF	12.5	Smooth surface with slight damage
GD	22.5	Smooth surface with slight damage	XF	35.5	Rough surface
FZ	19.5	Smooth surface with slight damage	FBF	31	Rough surface
