Abstract

Objectives: We examined the surface gloss and roughness of a dental composite and human enamel after brushing with a new bioactive glass (BCF201) additive designed to treat dentine hypersensitivity.

Methods: We prepared 2 cohorts of samples: a resin-based composite (RBC) and human enamel. Each cohort received 20 000 brushing cycles with Colgate Optic White Enamel (Colgate Optic), Sensodyne Whitening Repair and Protect (Sensodyne), Colgate Enamel Health Sensitivity Relief (Colgate-EN) with and without BCF201 added or Germiphene Gel 7 HT (Gel 7) with and without BCF201 added. The average gloss and roughness of the enamel and RBC surfaces were measured before brushing and after 20 000 back-and-forth brushing cycles. A linear regression function was applied to the gloss results, and the data were analyzed using ANOVA and a Tukey post-hoc test (α = 0.05).

Results: After 20 000 brushing cycles, the control (Gel 7) had no significant effect on the gloss or roughness of the RBC. However, the choice of dentifrice had a significant effect on both gloss and roughness (p < 0.001). With respect to RBC, after brushing, surface roughness was ranked from smoothest to roughest: Gel 7 = Gel 7 plus BCF201 > Colgate-EN plus BCF201 = Colgate Optic = Colgate-EN > Sensodyne. With respect to enamel, the smoothest to the roughest surfaces after brushing were: Gel 7 plus BCF201 = Sensodyne = Colgate-EN plus BCF201 > Gel 7 = Colgate Optic = Colgate-EN.

Conclusion: The bioactive glass additive had no adverse effect on the surface roughness or gloss of human enamel or RBC.

Significance: The addition of BCF201 appears to have a polishing effect on RBC and enamel and reduced the abrasive effects of Colgate-EN on RBC and enamel.

用商业和改良的牙膏刷牙后，牙釉质和树脂复合表面的光泽保持。

目的:我们用一种新型生物活性玻璃(BCF201)添加剂治疗牙本质过敏后，检测牙齿复合材料和人牙釉质的表面光泽度和粗糙度。方法:我们制备了2组样品:树脂基复合材料(RBC)和人牙釉质。每组受试者使用添加和不添加BCF201的高露洁光学白牙釉质(Colgate Optic)、Sensodyne美白修复和保护(Sensodyne)、高露洁牙釉质健康敏感缓解(Colgate- en)或添加和不添加BCF201的Germiphene Gel 7 HT (Gel 7)进行2万次刷牙。在刷牙前和前后刷牙2万次后，测量牙釉质和红细胞表面的平均光泽度和粗糙度。对光泽度结果应用线性回归函数，并使用方差分析和Tukey事后检验对数据进行分析(α = 0.05)。结果:在2万次刷牙循环后，对照组(凝胶7)对红细胞的光泽和粗糙度没有显著影响。然而，牙膏的选择对光泽和粗糙度都有显著影响(p < 0.001)。RBC涂刷后表面粗糙度从光滑到粗糙依次为:Gel 7 = Gel 7 + BCF201 >高露洁- en + BCF201 =高露洁Optic =高露洁- en > Sensodyne。对于牙釉质，刷后最光滑到最粗糙的表面为:凝胶7 + BCF201 = Sensodyne =高露洁en + BCF201 >凝胶7 =高露洁Optic =高露洁en。结论:生物活性玻璃添加剂对人牙釉质和红细胞的表面粗糙度和光泽度无不良影响。意义:BCF201的加入对红细胞和牙釉质有抛光作用，降低了高露洁en对红细胞和牙釉质的磨蚀作用。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
