Abstract

Purpose: To study the effect of different cleaning methods on the shear bond strength of self-adhesive resin cement to saliva-contaminated high translucency zirconia and surface wettability.

Methods: Eighty zirconia specimens were randomly divided into 5 groups (n=16), i.e., control group(not contaminated), 75% ethanol group,cleaning paste group,airborne-particle abrasion group, and atmospheric pressure cold plasma group. The contact angles was measured, shear bond strength were examined, and fracture types were determined. SPSS 26.0 software package was used for statistical analysis of the data.

Results: The atmospheric pressure cold plasma group produced the lowest contact angle(P＜0.05). The shear bond strength of the airborne-particle abrasion group, the cleaning paste group and the atmospheric pressure cold plasma group respectively were similar to the control group without significant difference(P＞0.05), while those were significantly higher than 75% ethanol group(P＜0.05). The mixed fracture mode of the atmospheric pressure cold plasma group evidently increased.

Conclusions: Airborne-particle abrasion, cleaning paste and atmospheric pressure cold plasma overcome the effects of saliva contamination, producing the shear bond strength to zirconia similar to the control group. The atmospheric pressure cold plasma improves hydrophilicity of high translucency zirconia significantly.

[不同清洁方法对高透明度氧化锆粘接强度和表面润湿性的影响]。

目的：研究不同清洁方法对自粘树脂水泥与唾液污染的高透明度氧化锆的剪切粘结强度和表面润湿性的影响：将 80 个氧化锆试样随机分为 5 组（n=16），即对照组（未受污染）、75% 乙醇组、清洁膏组、空气颗粒磨损组和常压冷等离子组。测量接触角，检查剪切结合强度，并确定断裂类型。使用 SPSS 26.0 软件包对数据进行统计分析：结果：常压冷等离子体组的接触角最小（P＜0.05）。气载颗粒磨削组、清洗膏组和常压冷等离子体组的剪切粘接强度分别与对照组相似，无显著差异（P＞0.05），但显著高于 75% 乙醇组（P＜0.05）。常压冷等离子组的混合断裂模式明显增加：结论：空气颗粒磨、清洁膏和常压冷等离子体克服了唾液污染的影响，与氧化锆的剪切结合强度与对照组相似。常压冷等离子体能显著改善高透明度氧化锆的亲水性。
