Comparative evaluation of mean gingival scores between two groups

Group	Gingival index (mean ± SD)			P value intragroup
	0th day	30th day	90th day	0–30 day	0–90 day	30–90 day
Group A (neem gel)	1.57 ± 0.13	1.02 ± 0.17	0.83 ± 0.14	<0.001**	<0.001**	<0.001**
Group B (CHX gel)	1.55 ± 0.13	1.05 ± 0.17	0.87 ± 0.15	<0.001**	<0.001**	<0.001**
P value intergroup comparison	0.602	0.641	0.291	–	–	–

SD = standard deviation, CHX = chlorhexidine

**P < 0.001––statistically highly significant
