Description
Summary:	To analyze biochemical and microbiological parameters of the saliva of institutionalized elders and to investigate the relation of these parameters with edentulism, use of dentures and presence of biofilm. A cross-sectional study carried was out in seven long-term institutions. Samples (n=161) of unstimulated saliva were collected for analysis of salivary flow, quantification of total proteins and identification of microorganisms. Oral examination was carried out to verify the number of missing teeth, the use of dentures and the presence of visible biofilm on the surface of teeth and dentures. Associations were performed using chi-square or Fisher's exact test (α<0.05). Mann-Whitney Test was used to identify differences in the salivary flow and total proteins (α<0.05). There was no association between the type of edentulism and use of dentures with biochemical and microbiological parameters of saliva ( >0.05). Associations were observed between the presence of dentures biofilm and the colonization of sp. ( =0.038) and sp. ( =0.03). The absence of teeth and use of dentures do not influence the amount of total proteins and the microorganisms count in saliva. Denture biofilms are associated with the presence of sp. and sp. in saliva of institutionalized elders. Candida, long-stay institutions for elders, saliva, Streptococcus, Staphylococcus.
