Resumo: The aim of this in vitro study was to evaluate the influence of pH levels on force decay and cytotoxicity of elastic chains submersed in artificial saliva. The samples were divided into two groups: Group SF (Polyurethane elastic, super force) and Group C (Polyurethane elastic, conventional), which were stretched to 100% of their initial length. They were kept in artificial saliva solutions at pH levels of 5.0, 6.0 and 7.5 for time intervals of 10 seconds, 1, 14 and 28 days. Cytotoxicity assay was performed in cells (L929-fibroblast), subjected to "dye-uptake" test. ANOVA, Sidak method and Tukey’s test were used. The pH did not interfere directly in force decay results of tested elastics. Cytotoxicity test showed that Group SF presented similar cell viability when compared with Group C. There was gradual reduction in cell viability from beginning to 28th day. The pH had no significant influence on force decay and cytotoxicity. Time had more influence and contributed to variability in results.
