Type of hybrid reinforced composite	Density (g/cm³)	Water absorption (%)	Thickness swelling (%)
G1	1.32 (0.06)^a	0.00 (0.00)^a	0.00 (0.00)^a
G2	1.33 (0.08)^a	0.86 (0.06)^c	0.33 (0.02)^b
G3	1.39 (0.03)^a	1.21 (0.01)^d	1.77 (0.01)^d
GS1	1.31 (0.11)^a	0.41 (0.13)^b	0.00 (0.00)^a
GS2	1.33 (0.09)^a	0.84 (0.01)^c	0.32 (0.03)^b
GS3	1.35 (0.06)^a	2.07 (0.03)^e	0.48 (0.02)^c

Values in parentheses are SDs.
Values followed by the same letter are not statistically different (p < 0.05) according to Duncan’s multiple-range test.
