Mean values of zone of inhibition of periodontopathic bacteria

Groups	Periodontopathic bacteria (mean ± SD)
	Aggregatibacter actinomycetemcomitans	Porphyromonas gingivalis	Prevotella intermedia
1% CLE solution	26.94 ± 1.52	23.81 ± 1.35	21.83 ± 1.66
0.2% CHX solution	24.67 ± 1.23	24.92 ± 1.22	23.71 ± 1.41
P-value	0.55 ns	0.62 ns	0.61 ns

CHX = chlorhexidine, CLE = Curcuma longa extract, ns = not significant, SD = standard deviation

*P ≤ 0.5, significant.
