– Plaque was grown for 3d by caries‐active and caries‐inactive subjects during a daily consumption of 10 tablets made of sucrose, sucrose with a 3% addition of NaHCO 3 + KH 2 PO 4 combination (mole ratio 9.82/1), the same with 10 parts/10 6 fluoride as NaF in the sucrose or sucrose with 10 parts/10 6 F. Plaque samples were obtained before, during and after ingestion of these tablets. The extracellular sodium and potassium contents of the plaque, calculated against the nitrogen of the plaque material, exhibited changes which were in part attributable to the activation of the plaque organisms during fermentation of sucrose or to inhibition exerted by the additives, in particular by the fluoride. The sodium values suggested that it was diffusing into the plaque.
