Intracanal microbiological conditions and E. faecalis density in the adjacent dentin in .

Groups	Root canal culture		Equivalent density of E. faecalis
Control (n=10)	Positive (n=6)	0.97 a	elevated
	Negative (n=4)	0.37 b	moderate
Conventional regimen (n=10)	Positive (n=6)	0.44 b	moderate
	Negative (n=4)	0.01 c	residual
Alternating regimen (n=10)	Negative (n=10)	0.17 c	residual
