Abstract (EN): The Denture-Induced Stomatitis (DIS), affects almost half of Portuguese population wearing upper removable prosthesis and is clearly associated to the infection by yeasts. Considering its prevalence, it becomes important understand the predisposing factors that are associated with DIS. One of those factors is the saliva, whose quantity and pH can conditioned the growth of yeasts in the oral cavity. The principal aim of this study was to research the possible relationship of the saliva (quantity and pH) with the presence of yeasts and DIS. The studied population was constituted by 99 adult individuals of both sexes, wearing maxillary acrylic prosthesis that frequented the consultation of Removable Prosthesis of FMDUP. The study of the saliva was done with Dentobuff® Strip (determination of the rate of secretion and the pH of the stimulated saliva). Then it was done the microbiological exam of the saliva in Sabouraud Dextrose Agar and evaluation of the microbial growth, through UFC counting. We verified that the relationship between the quantity of saliva and the presence of yeasts is statistically significant (p=0,041); the same is not true to the presence of DIS (p=0,830). Relatively to the pH, the comparative statistical analysis between the groups with and without DIS gives us a p=0,205, so didn't exist statistic significant differences between the two groups. However, relatively to the presence of yeasts the difference of the saliva pH between the two groups was statistically significant (p=0,007). Conclusion: The smallest quantity and the low pH of the saliva are directly associated with the presence of yeasts, but not with the existence of DIS. <br> <br> Key-words: Removable Prosthesis; Denture-Induce Stomatitis; Saliva <br> <a target=
