Background To overcome the traditional problems, including compromised mechanical strength, wear resistance, and aesthetics associated with conventional glass ionomer cement (CGIC) materials, resin-modified glass ionomer cement (RMGIC) was introduced in 1989. RMGIC maintains the clinical advantages of CGIC, such as fluoride release and simplicity in clinical operation, and is more aesthetically pleasing than CGIC. 

Aim This study aimed to evaluate the solubility of resin-modified glass ionomer cement in various energy beverages at different modes of curing [soft start, fast, pulse] by charging plug dual-use Ly-B200 light cure device.

Materials and methods 60 standardized discs were fabricated from a resin-modified glass ionomer cement and divided into three main groups according to the type of curing mode 20 each (soft start, fast, and pulse). All specimens were immediately weighed. Four commercially available beverages were used as immersion media. The pH of the beverages was measured using a digital pH meter. Then each main group was divided into four groups according to types of solution: 5 specimens each (High Protein powder, Red bull, Creatine, and C4), then the specimens were dried and weighed again after immersion. The data collected for the specimen's weight before and after immersion in the sport drinking solution were then expressed as mean ± standard deviation and compared between two groups by Student's t-test. A one-way ANOVA was used for multiple group comparisons. (p < 0.05).

Results: For all modes of light cure, the highest solubility among the energy beverages was recorded for specimens immersed in Red Bull, while the lowest solubility was recorded when the specimens were immersed in protein powder. The pulse mode recorded the highest solubility in all specimens, while the soft start mode recorded the lowest solubility for all specimens.
