This study aimed to compare the effects of alcohol-containing and alcohol-free mouthwashes on the surface roughness of bulk-fill composite resins. In this in-vitro, experimental study, 60 composite specimens measuring 6 mm in diameter and 2 mm in height were fabricated from Tetric N-Ceram and X-tra fil composite resins using a stainless-steel mold. After curing for 20 s, the specimens were immersed in distilled water and incubated at 37 °C for 24 h. Baseline roughness was measured before dividing them into three groups for immersion in water, alcohol-containing, or alcohol-free Listerine for 24 h, simulating two years of use. The specimens were then dried at room temperature, and their surface roughness was measured again. Data was analyzed by two-way ANOVA and t-test (α = 0.05).
No significant change occurred in surface roughness of specimens after immersion in the respective solutions (P > 0.05). The type of composite and the type of solution had no significant effect on the surface roughness of specimens (P > 0.05). The results showed that Listerine alcohol-containing and alcohol-free mouthwashes had no significant effect on the surface roughness of the tested bulk-fill composite resins and no significant difference with each other in this respect.
本研究旨在比较含酒精和不含酒精的漱口水对大块充填复合树脂表面粗糙度的影响。在这项体外实验研究中，使用不锈钢模具由Tetric N-Ceram和X-tra fil复合树脂制作了60个直径6毫米、高2毫米的复合树脂样本。固化20秒后，将样本浸入蒸馏水中，并在37°C下孵育24小时。在将它们分成三组分别浸入水、含酒精或不含酒精的李施德林漱口水24小时（模拟两年使用时间）之前，测量基线粗糙度。然后将样本在室温下干燥，并再次测量其表面粗糙度。数据通过双向方差分析和t检验进行分析（α = 0.05）。
样本浸入各自溶液后，表面粗糙度没有显著变化（P > 0.05）。复合材料类型和溶液类型对样本表面粗糙度没有显著影响（P > 0.05）。结果表明，含酒精和不含酒精的李施德林漱口水对测试的大块充填复合树脂表面粗糙度没有显著影响，在这方面彼此之间也没有显著差异。
