Objective: to assess the hydrogenic potential and salivary volume before and after using menthol chewing gum in healthy volunteers. Method: this is a quantitative, quasi-experimental, pre-test and post-test study, carried out with 45 healthy volunteers between 18 and 60 years old. The saliva sample was collected in a non-stimulated manner, following the spitting method. Volunteers were asked to accumulate saliva in their mouths and spit it out into a millimeter flask, every minute, before and after receiving the menthol chewing gum, for ten minutes at each step. Results: in the first stage of collection, the mean hydrogenic potential was 7.06, increasing to 7.42 (p<0.001) after the second stage. Salivary volume increased from 5.95 mL to 23.13 mL (p<0.001). Conclusion: chewing gum after eight hours of fasting caused an increase in the hydrogenic potential and salivary volume. This increase in salivary volume has no clinical relevance for bronchoaspiration.
