TABOADA ALVEAR, María Fernanda et al. Degradation of resin-modified glass ionomer in contact with different mouthrinses: in vitro study. Odontología Vital [online]. 2018, n.28, pp.15-24. ISSN 1659-0775.

Objectives: to evaluate changes in mass and roughness of glass ionomer in contact with mouthrinses considering time of exposure and their composition. Materials and Methods: 88 Ionolux and Vitremer glass ionomer test bodies were made and kept in contact with alcohol-free Listerine Zero, Cool Mint, with alcohol, and Whitening with alcohol and bleaching agents during 21, 546 and 1092 minutes with cycles of permanence of specimens in artificial saliva, weighing and profilometer tests were carrying out in a continuous way. Results: The data tabulated and analyzed by ANOVA test showed degradation in samples without any statistically significant difference evidenced even in roughness, it is proportional to time of exposure. Conclusions: There are changes in weight and roughness on ionomers evaluated aftercontact with different mouth rinses used proportional to time of exposure. The presence of alcohol in the mouthwash does not determine greater change in the mass of evaluated materials; but roughness does in comparison with other mouth rinse compositions and exposure time.
