Glass ionomer cement (GIC) releases fluorides and has good biocompatibility, carbonated drinks, sometimes known as fizzy drinks, are carbonated liquids that contain dissolved carbon dioxide, sweeteners, and natural or artificial flavoring. The aim of our study is to determine the flexural strength of GIC after immersing in carbonated beverages. Twelve samples of GIC filling material were used among which six samples prepared were from the Dtech brand and six were prepared from the Shofu brand for the study. Bar-shaped specimens were prepared from each group with the dimension of 2 mm × 2 mm × 25 mm. They were immersed in Sprite, fizz drinks, and in distilled water as a control group. The immersion period was 7 days. Then, the determination of maximum force and displacement was done using INSTRON E3000 (ElectroPuls) universal testing machine, then the collected data were used to determine flexural strength. The mean flexural strength of Dtech GIC was 24.84 ± 6.523 Mpa. The mean flexural strength of Dtech GIC was 18.57 ± 11.60 Mpa. The independent sample -test showed that = 0.247 (>0.05) which was statistically not significant. The flexural strength of GIC material decreased after being immersed in Sprite and fizz drinks.
玻璃离子水门汀（GIC）能释放氟化物且具有良好的生物相容性。碳酸饮料，有时也被称为汽水，是含有溶解二氧化碳、甜味剂以及天然或人工调味剂的碳酸液体。我们研究的目的是测定GIC浸泡在碳酸饮料后的弯曲强度。本研究使用了12个GIC填充材料样本，其中6个样本由Dtech品牌制备，6个由松风（Shofu）品牌制备。从每组中制备尺寸为2毫米×2毫米×25毫米的条形试样。它们被浸泡在雪碧、汽水以及作为对照组的蒸馏水中。浸泡期为7天。然后，使用英斯特朗E3000（ElectroPuls）万能试验机测定最大力和位移，之后利用收集到的数据确定弯曲强度。Dtech GIC的平均弯曲强度为24.84±6.523兆帕。松风GIC的平均弯曲强度为18.57±11.60兆帕。独立样本t检验显示，P = 0.247（>0.05），在统计学上无显著差异。GIC材料浸泡在雪碧和汽水后弯曲强度降低。
