The amount of Ca mobilised by potassium citrate and citric acid was approximately 10-fold greater than that extracted with potassium oxalate and oxalic acid.
In the case of oxalate, the oxalic acid released significantly greater quantities of Ca than the potassium oxalate. Indeed, the potassium oxalate actually decreased the amount of Ca in solution relative to that observed in the distilled water extractions.
The non-immediate effect of potassium oxalate could be compared to the APF gel agent.
Effectiveness of potassium oxalate treatment on dentin hypersensitivity.
Blood was drawn in tubes with 1.8 g/L [K.sub.3]EDTA (Vacutainer Tube; Becton Dickinson), in tubes with 2.5 g/L sodium fluoride and 2 g/L potassium oxalate
as anticoagulant (Vacutainer Tube), in tubes with 0.5 mol/L acidic citrate (Biopool Stabilyte[TM]), and in tubes with a mixture of the sodium fluoride, potassium oxalate
, and acidic citrate.
