Mean Spleen Weight following Pulpal Infection with Pathogens

Experimental Group	Mean Spleen Weight (g) ± SD
A (SCID/T. denticola)	0.13 ± 0.02*
B (SCID/red complex)	0.10 ± 0.02*
C (WT/T. denticola)	0.13 ± 0.02*
D (WT/red complex)	0.12 ± 0.02*
Control (WT, no infection)	0.06 ± 0.01

SD, standard deviation

^*p < 0.05 vs. non-infected controls. There were no significant differences among the infected groups.
