Rapid Griess assay (RGA): a chairside test for <i>ex vivo</i> semi-quantitative oral nitrite measurement and <i>in vitro</i> assessment of nitrite production by oral bacteria
The RGA provided stable and reliable results for chairside NO<sub>2</sub> <sup>-</sup> semi-quantitation, and revealed elevated and stable NO<sub>2</sub> <sup>-</sup> levels on the tongue. <i>In vitro</i>, bacterial NO<sub>2</sub> <sup>-</sup> production was consistent with the available literature, but uncertainty remains regarding <i>Neisseria</i> spp. Our results showed promise for clinical and research applications of the RGA.
