摘要:
SummaryThe effect of incorporated CaF2(2.04%), NaF (2.27%) and amine fluoride (0.71%) in acrylic resin plates, on bending strength and fluoride release by rinsing and immersion in synthetic saliva, was determined. Bending strength was reduced by 6.7, 9.5 and 20% respectively. The most elevated release of fluoride from the NaF containing—and the most protracted from the CaF2containing—plates may be related to the solubilities of the compounds.It appears that the organic molecule of the AmF compound affects the strength of the acrylic plates most significantly.The F‐ concentrations released in thein vitrorinsing experiment may be presumed to occur in vivo at some higher level due to the larger size of dental appli
