Table 1. Mean values and standard deviation for the diameter of zones of inhibition.

Organism	Mean ± SD (cm)
	G-CGF	L-CGF	CHX (positive control)
Staphylococcus aureus	0.92 ± 0.10 *	1.26 ± 0.12 *	2.51 ± 0.32
Streptococcus mutans	1.27 ± 0.23 *	1.20 ± 0.06 *	2.83 ± 0.36

Abbreviations: CHX, chlorhexidine (0.12%); CGF-G, concentrated growth factor gel; CGF-L, liquefied concentrated growth factor; SD, standard deviation.

Note: There is significant difference of G-CGF and L-GCF compared with CHX in both S. aureus and S. mutans .
