Table 1.

Percentage of FGF-2 and VEGF stained areas (%) on tension and pressure sides of the three experimental groups.

	FGF-2		VEGF
	Tension	Pression	Tension	Pressure
Group 1	2.40 ± 0.69^a	11.25 ± 3.30^a*	1.28 ± 0.52^a	7.56 ± 2.34^a*
Group 2	3.16 ± 0.96^a	2.06 ± 0.94^b	3.78 ± 1.04^b	2.70 ± 0.54^b
Group 3	6.63 ± 1.07^b	6.56 ± 0.77^c	3.83 ± 1.25^b	3.20 ± 0.66^b

Values account for mean and standard deviation (±). Different letters on the column indicate statistically significant difference between groups as well as between tension and pressure sides (P < 0.05).
