Composites sorption and solubility can be precursors of several chemical and physical processes, which lead to deleterious effects on the polymer structure. This study evaluated the effect of mouthwashes with and without alcohol on the sorption and solubility of conventional and low viscosity bulk fill resins.
Four types of Bulk Fill resins (Filtek™ Bulk Fill, X-tra Fil, Filtek™ Bulk Fill Flow and X-tra Base) were submitted to the following mouthwashes: Listerine Cool Mint and Periogard (containing alcohol) and Listerine Zero and Periogard (alcohol-free). The specimens were stored in the mouthwashes for seven days. Solubility and sorption tests were performed according to ISO 4049. Data were analyzed using two-way-ANOVA, followed by Tukey Test. The data were grouped, and a paired t-test was performed to evaluate the effect of alcohol on the properties studied. The p was fixed at 5%.
Resins immersed in alcohol-containing mouthwashes had higher values of sorption and solubility, with the highest sorption rate for X-Tra Base in Listerine Cool Mint treatment (<0.05). Flow type resins showed higher sorption than conventional viscosity resins, irrespective of the mouthwash used (<0.05).
Alcohol-containing mouthwashes affected sorption and solubility of bulk fill resins and the composites that presented worse and better performance regarding the studied properties were X-Tra Base and Filtek™ Bulk Fill, respectively. Solubility, Sorption, Mouthwashes, Bulk-fill composites.
复合材料的吸附和溶解性可能是多种化学和物理过程的先兆，这些过程会对聚合物结构产生有害影响。本研究评估了含酒精和不含酒精的漱口水对传统和低粘度大体积充填树脂吸附和溶解性的影响。
四种类型的大体积充填树脂（Filtek™大体积充填树脂、X-tra Fil、Filtek™大体积充填流动树脂和X-tra Base）分别用以下漱口水处理：劲爽薄荷味李斯德林漱口水和派丽奥漱口水（含酒精）以及李斯德林零酒精漱口水和派丽奥（无酒精）。将标本在漱口水溶液中储存七天。根据ISO 4049进行溶解性和吸附测试。使用双向方差分析对数据进行分析，随后进行Tukey检验。对数据进行分组，并进行配对t检验以评估酒精对所研究性能的影响。设定p值为5%。
浸泡在含酒精漱口水的树脂具有更高的吸附和溶解性值，在劲爽薄荷味李斯德林漱口水处理下，X-Tra Base树脂的吸附率最高（<0.05）。无论使用何种漱口水，流动型树脂的吸附率均高于传统粘度树脂（<0.05）。
含酒精漱口水会影响大体积充填树脂的吸附和溶解性，在所研究性能方面表现较差和较好的复合材料分别是X-Tra Base树脂和Filtek™大体积充填树脂。溶解性、吸附、漱口水、大体积充填复合材料。
