Carbonated beverages have side effects on oral health and general health. Flexural strength is a prime mechanical property of restorative material. The aim of this study is to know the effect of carbonated beverages on the flexural strength of composite restorative material. Two types of composites (Ivoclar and Restofill) were used as samples for comparative evaluation of flexural strength. The sample size is 10 where 5 of each type of composites are included. The obtained samples were immersed in carbonated beverages. One sample of each type was used as a control. After 24 h, the flexural strength of all the 10 samples was evaluated using the formula (3FL/2bd), and the values were tabulated. Average values and graphs were done using SPSS software. The results showed the changes in flexural strength of both Ivoclar and Restofill materials when immersed in carbonated beverages. The mean value of all the samples was taken, and the standard deviation was calculated. After immersion in carbonated liquids, the mean value of Ivoclar and Restofill samples is 58.9 and 35.01, respectively. = 0.718 (>0.05), which was not statistically significant. After immersion in Coke, the Restofill group exhibits more flexural strength than the Ivoclar group composite; however, the strength reduces when immersed in Sprite as compared to the Ivoclar group composite.
碳酸饮料对口腔健康和整体健康有副作用。弯曲强度是修复材料的一项主要力学性能。本研究的目的是了解碳酸饮料对复合修复材料弯曲强度的影响。两种复合材料（义获嘉和瑞斯托菲尔）用作弯曲强度比较评估的样本。样本量为10，每种复合材料各包含5个。将获得的样本浸泡在碳酸饮料中。每种类型的一个样本用作对照。24小时后，使用公式（3FL/2bd）评估所有10个样本的弯曲强度，并将数值制成表格。使用SPSS软件得出平均值和图表。结果显示了义获嘉和瑞斯托菲尔材料浸泡在碳酸饮料中时弯曲强度的变化。计算所有样本的平均值和标准差。浸泡在碳酸液体中后，义获嘉和瑞斯托菲尔样本的平均值分别为58.9和35.01。P = 0.718（>0.05），无统计学意义。浸泡在可乐中后，瑞斯托菲尔组比义获嘉组复合材料表现出更高的弯曲强度；然而，与义获嘉组复合材料相比，浸泡在雪碧中时强度降低。
