Light curing power (mW/cm ² )	N	Light curing time, Mean (SD)
Light curing power (mW/cm ² )	N	1 Second	3 Seconds	5 Seconds
1000	10	104.2 (11.6) ^A,a	109.9 (16) ^A,a	147.4 (26.7) ^A,b
1600	10	105.9 (15.7) ^A,a	145.1 (17.5) ^B,b	152.6 (9.9) ^A,b
2300	10	130.3 (11.3) ^B,a	147.1 (12.7) ^B,b	174 (10.3) ^B,c

N, Number of specimens; SD, Standard deviation.

Values marked with different uppercase letters (A-B) indicate a significant difference between the different means within the same column. Values marked with different lowercase letters (a-c) indicate a significant difference between the different means within the same row (P < 0.05).
