摘要

目的:评估 COVID-19 预防性漱口水对三种不同聚合物基复合 CAD/CAM 材料(Vita Enamic (ENA)、Grandio Block (GB)、Lava Ultimate (LU))的表面硬度、表面粗糙度 (Ra) 和颜色变化 (ΔE)的影响。方法:通过对三种不同的 CAD/CAM 块进行切片,共获得 100 个尺寸为 2 mm × 7 mm × 12 mm 的矩形试样,并按照漱口水浸泡 30 天的方案随机分为以下 5 个亚组:对照组:人工唾液;PVP-I:1% 聚维酮碘;HP:1.5% 过氧化氢;CPC:含 0.075% 氯化十六烷基吡啶的漱口水;EO:含精油的漱口水。微硬度、Ra 和 ΔE 值分别在基线和浸泡 30 天后测量。结果:独立因素(材料和溶液)对显微硬度和颜色有显著影响(p < 0.001)。材料的 Ra 值不受任何漱口水的影响(p > 0.05)。在 PvP-I 和 HP 中浸泡后,每种材料的显微硬度和颜色都有显著变化(p < 0.05)。结论:在本研究的局限性范围内,研究发现在 1%的 PvP-I 和 1.5% 的 HP 漱口水中浸泡 30 天后,测试的聚合物基复合 CAD/CAM 材料的表面硬度和颜色容易发生降解和变化。

Effects of different antiviral mouthwashes on the surface roughness, hardness, and color stability of composite CAD/CAM materials
Objective:To evaluate the effect of COVID-19 preventive mouthwashes on the surface hardness, surface roughness (Ra), and color change (ΔE) of three different polymer-based composite CAD/CAM materials (Vita Enamic (ENA), Grandio Block (GB), Lava Ultimate (LU)).Methods:A total of 100 rectangular-shaped specimens with dimensions of 2 mm × 7 mm × 12 mm were obtained by sectioning three different CAD/CAM blocks and randomly divided into five subgroups according to the 30 days of mouthwash immersion protocol as follows: Control: artificial saliva, PVP-I: 1% povidone-iodine, HP: 1.5% hydrogen peroxide, CPC: mouthwash containing 0.075% cetylpyridinium chloride, EO: mouthwash containing essential oils. Microhardness, Ra, and ΔE values were measured at baseline and after 30 days of immersion protocols. Data were analyzed using the Wald Chi-square, two-way ANOVA, and post hoc Tukey tests.Results:The independent factors (materials and solutions) significantly influenced the microhardness and color ( p < 0.001). Ra of the materials was not affected by any of the mouthwashes ( p > 0.05). The microhardness and color of each material varied significantly after immersion in PvP-I and HP ( p < 0.05). The highest percentage change in microhardness, Ra, and ΔE was found in LU immersed in PvP-I and HP mouthwashes, while the lowest change was found in ENA groups ( p < 0.05).Conclusion:Within the limitations of this study, it was found that the surface hardness and color of tested polymer-based composite CAD/CAM materials are susceptible to degradation and change after 30 days of immersion in 1% PvP-I and 1.5% HP mouthwashes.
