Fluoride bioavailability in saliva during acute psychological stress
Central European Journal of Medicine, 05/30/2012
Naumova EA et al. – In all analyses, the alpha–level was set at 0.05. Public speaking significantly increased state anxiety and salivary cortisol concentrations. Acute stress did not influence salivary secretion rates. In the AmF group, stressed individuals exhibited statistically significant lower fluoride concentration in saliva compared with the nonstressed subjects Acute psychological stress reactions do not cause hyposalivation but decrease fluoride bioavailability after using a dentifrice containing AmF. Fluoride bioavailability during acute stress is dependent on fluoride formulation.
