“…Borges et al [ 33 ] evaluated the Vickers hardness, diametral tensile strength, and elastic modulus of XBF RBC specimens after 30 days of immersion in CC beverage and observed a substantial reduction in each property in contrast to the control group. In a recent study, Degirmenci et al [ 43 ] investigated the elastic modulus, microhardness, and flexural strength parameters of the Estelle bulk-fill flow RBC (Tokuyama Dental Corporation, Tokyo, Japan) after 1 day, 7 days, 30 days, and 365 days storage in OJ and CC beverages. According to their findings, all parameters significantly declined after each storage cycle and, in particular, the flexural strength of the material did not meet the ISO 4049 standard following short and long-term immersion cycles.…”

During the last 10 years, various companies have marketed different “bulk-fill” resin dental composites for the restoration of posterior stress-bearing teeth; however, the impact of acidic conditions on these relatively newer materials has not been thoroughly investigated. Therefore, an attempt was made to evaluate the effect of acidic beverages on the mechanical biomimetic characteristics of four bulk-fill and one conventional nanohybrid resin-based dental composites (RBCs). The specimens of each RBC were stored in two acidic beverages namely ‘Orange Juice’ and ‘Coca-Cola’, whereas ‘dry’ and ‘distilled water’ storage of specimens served as controls. After 1 week of storage, flexural and surface hardness properties of specimens were determined using a universal testing machine and Vickers hardness tester, respectively. In general, the ‘Coca-Cola’ beverage caused the greatest degradation of flexural strength, flexural modulus, and surface hardness characteristics in all RBCs in contrast to the ‘dry’, ‘distilled water’ controls and ‘Orange Juice’ storage conditions. However, the overall mechanical biomimetic performance of nanohybrid RBCs was relatively better than all other bulk-fill RBCs and may, therefore, be considered a suitable candidate for the restoration of posterior stress-bearing permanent dentition.

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/2bd2), 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. P = 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.
