Background and Aim There has been an increased availability and consumption of energy drinks within the young population. The potential undesirable effects of energy drinks have been discussed worldwide. However, there is limited information about the accessibility of energy drinks in Australia. Dental composite resins are increasing in popularity for aesthetic restorations among dental professionals and patients. Increased exposure to energy drinks within the oral environment is a concern as they have the potential to discolour and degrade composite resin materials. The purpose of this study was to evaluate the availability and affordability of energy drinks in metropolitan and regional New South Wales, Australia and to evaluate the effects of several energy drinks on two types of tooth coloured restorative material. Methods 31 shops throughout metropolitan NSW and 23 shops in regional NSW were surveyed to evaluate the availability and price of energy drinks. Disc samples made out of flowable and packable composite resins were immersed in 3 types of energy drinks [‘V’, ‘Redbull’ and ‘Rockstar’]. Images of each sample were acquired before immersion, 12-hours after immersion, and 1 week after immersion to evaluate the impact of the energy drinks on the colour of the composite discs. The masses of the discs were measured before and after 2 weeks of immersion to evaluate the solubility of the composite discs in the energy drinks. Results The most available energy products at both supermarkets and corner stores were Redbull, V, Mother, and Rockstar, respectively. Redbull and V were the least affordable, whereas the most affordable was Rockstar. In relation to the higher price for healthy foods in regional areas when compared to metropolitan areas, our study has found that there is a limited difference in affordability for different energy drinks. On the other hand, in vitro; after immersion in the selected energy drinks, flowable composite resin consistently exhibited more staining and higher solubility values compared to packable resin. The V energy drink contributed to the majority of staining for the flowable composite resin, as Rockstar did to the packable composite resin. Implications: Further studies are recommended to determine if all discretionary foods have comparable costs in both metropolitan and regional areas, corresponding to the results found for energy drinks in this study. Oral health promotion is needed for patients with composite resin restorations, as excessive energy drink consumption can compromise the aesthetic and physical properties of the restorations.
