Antimicrobial agents were used in the water coolant system in the high-speed dental drill during a series of tooth preparations on a model. Artificial saliva was applied to the dentition before the procedure began. For five minutes after cessation of drilling, the aerosols generated were collected on precipitation plates. Six agents reduced the bacterial counts to levels less than that recorded for water alone.
