Simultaneous pH and fluoride telemetry. A supplemental report.
Simultaneous telemetry of salivary fluoride and of interproximal plaqua pH at the entrance to an interproximal space was used to investigate the effects of sucrose-containing fluoride tablets dissolving in the vicinity of the fluoride and pH sensors. The dissolving of 1.0 mg fluoride-42 mg sucrose tablets caused only slight pH depressions ranging between 6.7 and 6.0 with concurrent increases in salivary F to as high as 190 ppm. Acid formation in interproximal plaque by fluoride-free, sucrose-containing placebo tablets decreased pH to 4.2.
