Procedures are provided to evaluate the effectiveness of slow-acting antibacterial agents such as metal salts on reduction of bacterial oral biofilm. In the modified process, the exposure time of the agent is increased from the usual 3 minutes to 7-15 minutes, e.g., about 10 minutes, and the duration increased to 5-12 days, e.g., about 8 days instead of the conventional 3 days. |
