Surface Roughness, Microhardness, and Microleakage of a Silorane-Based Composite Resin after Immediate or Delayed Finishing/Polishing

Table 2

Comparison of roughness (Ra, µm) means (± standard deviation) for the finishing and polishing systems studied according to application time.

	Control	Sof-Lex	Astropol	Enhance
Immediate	0.1933	0.4788	0.3803	0.4938
	(±0.0636)	(±0.1555)	(±0.1406)	(±0.1271)
Delayed	0.1913	0.4191	0.4365	0.4162
	(±0.0594)	(±0.1004)	(±0.1425)	(±0.1629)

Means followed by different lowercase letters show statistically significant differences between them, as compared in rows.
Means followed by the same capital letters do not show statistically significant differences between them,  as compared in columns.
