Table 4.
Viable bacterial cells and colony forming units remaining after irrigation with liposomal CHX and 2% plain CHX.
| Viable Bacteria/Colony Counts | Organism | Liposomal CHX | 2% CHX |
|---|---|---|---|
| Viable bacterium remaining after exposure to the drug for 12 h (µg/mL) | Staphylococcus aureus | ˃16 | ˃32 |
| Streptococcus mutans | ˃4 | ˃8 | |
| Fusobacterium nucleatum | >4 | >16 | |
| Colony counts of bacterium after 72 h of exposure (‘-‘ = No colonies) |
Staphylococcus aureus | - | >2 |
| Streptococcus mutans | - | >2 | |
| Fusobacterium nucleatum | - | - |
The results presented are the values from three replicates. CHX: Chlorhexidine digluconate.
