Comparative evaluation of mean Lactobacilli count expressed as 10³ CFU/mL of dental plaque between two groups

Group	Total colony count of Lactobacilli (mean ± SD)			P value intragroup
	0th day	30th day	90th day	0–30 day	0–90 day	30–90 day
Group A (neem gel)	9.46 ± 2.80	7.90 ± 2.04	6.16 ± 1.55	0.019*	<0.001**	0.008*
Group B (CHX gel)	8.667 ± 3.57	6.933 ± 2.01	4.80 ± 1.44	0.024*	<0.001**	0.004*
P value intergroup comparison	0.498	0.935	0.854	–	–	–

SD = standard deviation, CHX = chlorhexidine

*P < 0.05––statistically significant

**P < 0.001––statistically highly significant
