Abstract<br />

The role of saliva on Candida adhesion to biomaterials is not clearly <strong>de</strong>fined.<br />

Aim: this study investigated whether different periods of preconditioning with<br />

saliva would influence the adhesion of Candida albicans to a <strong>de</strong>nture base resin.<br />

Methods: samples (n=90) with smooth surfaces were ma<strong>de</strong> and then divi<strong>de</strong>d into<br />

five groups: 1 control - without saliva; 4 experimental groups – conditioned in<br />

saliva for periods of: 30, 60, 180 or 720 minutes. Candida adhesion was evaluated<br />

by crystal violet staining and XTT assay. Results: the one-way analyses of<br />

variance revealed that there were no significant differences among the mean<br />

numbers of adherent cells or among the mean absorbances for all groups. No<br />

significant correlation was found between the two methods used for assessing C.<br />

albicans adhesion. Conclusions: the different periods of preconditioning with<br />

saliva had no significant influence on the adhesion of Candida albicans to the<br />

<strong>de</strong>nture base acrylic resin.<br />

Key words: Acrylic Resins; Biofilms; Adhesion; Candida albicans; Saliva.
