Carbonic acid tablets promote submandibular-sublingual salivary secretion in humans

Carbonic acid tablets containing citric acid and sodium bicarbonate were designed to dissolve in aqueous solution, and release carbon dioxide (CO2). The effect of the carbonic acid tablets on salivary secretion was examined in humans. Healthy male volunteers participated in the whole salivary flow secretion (n = 6) and submandibular-sublingual (SMSL) gland and parotid gland salivary flow secretion (n = 12) studies. Placement of a carbonic acid...
