| Abstract: | The lactic acid produced in human dental plaque culture fluid is separated and determined by isotachophoresis.Experimental results showed that the recovery is in the range of 94.2%- 102.2%and the relative standard deviation is less than 4.5%,The quantities of lactic acid formed in dental plaque of the immune to caries are compared with those susceptible to caries under the same cultivation conditlons.The lactic acid produced at different time intervals with the dental plaque kept hungry has been determined and compared. |
| Keywords: | Isotachophoresis Lactic acid Human dental plaque. |
