Table 2.

Presents the post hoc pairwise comparison of percentage reduction in colony forming unit count among four groups

Group	P
2% CHX versus A. indica	1.000
2% CHX versus triphala	0.009*
2% CHX versus calcium hydroxide	<0.001*
A. indica versus triphala	0.050*
A. indica versus calcium hydroxide	<0.001*
Triphala versus calcium hydroxide	<0.001*

*A significant difference at P<0.05. Percent reduction in triphala group was significantly greater than the other three groups. A. indica showed a significantly greater reduction in CFU as compared to calcium hydroxide and a similar reduction to that of 2% CHX. Post hoc Bonferroni test. CFU: Colony forming unit, A. indica: Azadirachta indica, CHX: Chlorhexidine
