摘要

背景:漱口水在世界范围内的使用越来越多。然而,已知这些制剂对复合树脂牙科修复体具有负面影响。在这项研究中,我们旨在评估漱口水对这种修复体显微硬度的影响。方法:制备了30个Tetric N-Ceram复合材料样品。每个复合材料样品固化40秒,并在37°C的盐水溶液中保持24小时。使用Innovatest维氏显微硬度计记录每个试样的基线显微硬度。将复合样本随机放入20 mL选定的漱口水(高露洁®Plax、利斯特林®牙齿和牙龈防护以及Closeup®抗菌漱口水Cool Breeze)中,并在37°C的培养箱中储存24小时。接下来,重新检查显微硬度值。使用数字pH计记录每种类型漱口水的pH测量值。结果:由于高露洁®和利斯特林®的酸性性质,这些漱口水降低了修复体的显微硬度;Listerine®引起的显微硬度下降最大,pH读数最低(4.34)。对于Closeup®,中性pH(7.02),未发现对显微硬度的负面影响;相反,由于锌在后一种漱口水中的存在,发现显微硬度增加。结论:酸性漱口水对复合修复体显微硬度有负面影响。

Effect of mouthwashes on the microhardness of aesthetic composite restorative materials.

Background: Mouthwashes are increasingly being used worldwide. However, these preparations are known to have a negative impact on composite resin dental restorations. In this study, we aim to evaluate the effect of mouthwashes on the microhardness of such restorations.

Methods: Thirty specimens of Tetric N-Ceram composite were prepared. Each composite specimen was cured for 40 seconds and kept in saline solution for 24 hours at 37 °C. Baseline microhardness of each specimen was recorded using an Innovatest Vickers Micro Hardness Tester. Composite specimens were randomly placed in 20 mL of the selected mouthwashes (Colgate® Plax, Listerine® Teeth & Gum Defence, and Closeup® Antibacterial Mouthwash Cool Breeze) and stored in an incubator for 24 hours at 37 °C. Next, microhardness values were rechecked. pH measurements were recorded for each type of mouthwash using a digital pH meter.

Results: Due to the acidic nature of Colgate® and Listerine®, the microhardness of the restorations decreased with these mouthwashes; Listerine® caused the greatest decrease in microhardness and had the lowest pH reading (4.34). For Closeup®, with a neutral pH (7.02), no negative effect on microhardness was found; on the contrary, due to the presence of zinc in this latter mouthwash, an increase of the microhardness was found.

Conclusions: We confirm the negative effect of acidic mouthwashes on the microhardness of composite dental restorations.
