Two new saliva stimulants: V6 and a mucin containing chewing gum were tested in this placebo-controlled double-blind crossover study. Forty-three patients (mean age 63 yr) complaining of dry mouth participated. The products were administered in a randomized order, and used for 2 wk each. The effect was evaluated by interviews and by determining changes in stimulated and unstimulated saliva flow rates. A positive effect was reported by 64%, 44%, and 26% of the patients using the mucin chewing gum, V6, and the placebo, respectively. More than 2/3 of the patients found the mucin chewing gum efficient at various times and situations. Sixty-one percent of the patients preferred the mucin chewing gum, 21% V6, and 5% the placebo product. Fifty percent of the patients had an increase in unstimulated salivary secretion rate from all products after 14 days regular use indicating a long-term effect.
