p1 = The possibility in the comparison of breeding microorganisms on the toothbrushes in the control and chlorhexidine groups.

p2 = The possibility in the comparison of breeding microorganisms on the toothbrushes only in the control group.

p3 = The possibility in the comparison of breeding microorganisms only in the chlorhexidine group.

(P < 0.005 was accepted significant).
