摘要

目的:继发性龋病是口腔复合材料修复中的一个重要问题,在树脂复合材料的结构中加入纳米颗粒以提高其抗菌性能。本研究的目的是评估含有生物活性玻璃(BAG)和实验纳米锌-二氧化硅(NZS)配合物的复合材料的力学性能。方法:制备含70 wt%填料的实验性树脂复合材料,并作为对照样品。然后通过加入不同量的BAG(10%)、NZS(10%)、BAG和NZS(10% + 10%)对该实验树脂复合材料进行改性。通过将锌和二氧化硅研磨至纳米级,原位合成了NZS。采用万能试验机对其抗压强度和抗折强度进行了研究。数据分析采用单因素方差分析和Tukey事后检验。结果:填充量对抗压强度的影响无统计学差异,但对抗折强度的影响有统计学意义。虽然在树脂复合材料中加入抗菌剂会降低其物理性能,但这在临床上并不是不可接受的限制。结论:NZS具有较好的力学性能,但两种材料均可安全用于修复材料。如何引用这篇文章:tunaperdemir MT, Demirel MG。含生物活性玻璃和实验纳米锌-二氧化硅配合物的树脂复合材料的力学性能。国际医学杂志,2021;11(增刊1):137-42。https://doi.org/10.5577/intdentres.2021.vol11.suppl1.21语言修改:本手稿中的英语已由至少两名专业编辑检查,他们都是英语母语者。

Mechanical properties of resin composites containing bioactive glass and experimental nano zinc-silica complex
Aim: Secondary caries is an important problem in dental composite restoration, and nanoparticles are commonly added to the structures of resin composites to improve their antimicrobial properties. The aim of this study is to evaluate the mechanical properties of composite materials containing bioactive glass (BAG) and an experimental nano zinc-silica (NZS) complex. Methodology: An experimental resin composite containing 70 wt% filler was produced and used as a control sample. This experimental resin composite was then modified by adding different amounts of BAG (10%), NZS (10%), and both BAG and NZS (10% + 10%). NZS was synthesized in situ by milling zinc and silica to nanoscale level. Compressive strength and flexural strength were investigated using a universal testing machine. Data were analyzed using one-way ANOVA and the Tukey post-hoc test. Results: There were no statistically significant differences in compressive strength caused by the filler amount, but statistically significant changes were found in flexural strength. Although the addition of antimicrobial agents to resin composites reduces their physical properties, this is not a clinically unacceptable limit. Conclusion: NZS exhibits better mechanical properties than does BAG, but both materials can be used safely in restorative materials.   How to cite this article: Tunçdemir MT, Demirel MG.
