In view of the need for aesthetics, restorations of teeth will typically be completed using tooth colored restorative materials. With the advent of biomimetic restorative materials, such as glass ionomer cements (GIC), much greater emphasis is now being placed on how well such materials can resist the challenge of acids that are present in foods and drinks, or gastric contents that are regurgitated. This laboratory study compared the dissolution and behavior of five GIC materials (GC Fuji® VII, GC Fuji® Bulk, GC Fuji® IX Fast, Fuji® IX Extra and GC Equia® Forte Fil) when exposed to three acids (citric acid, phosphoric acid and lactic acid), versus ultrapure deionized water, which was used as a control. Discs of each material GIC were submerged in solutions and percentage weight changes over time determined. Subsequently, the GIC materials were also placed as a part of standardized Class II sandwich restorations in bovine teeth (n = 20), and submerged in the solutions, and the extent of GIC dissolution and protection of the adjacent tooth was scored. Weight loss increased with time and with acid concentration. Overall, the most soluble material was GC Fuji® IX Extra, while GC Fuji® IX Fast and GC Fuji® Bulk were less soluble, and the least soluble material was GC Equia® Forte Fil. The most destructive solution for both the discs and for GIC restorations in teeth was 10% citric acid, while the least destructive acid was 0.1% lactic acid. The more recent GIC materials GC Fuji® Bulk and GC Equia® Forte Fil showed increased acid resistance over the older GIC materials, and this further justifies their use in open sandwich Class II restorations in more hostile environments.
Background: There is a growing movement to increase palliative care consults from the emergency department (ED) to reduce healthcare costs and improve quality of life. The surprise question is a screening tool that emergency medicine physicians may be able to use towards achieving this goal. Objective: The objectives of this study were to increase awareness of hospice and palliative care medicine (HPM) among emergency medicine (EM) providers and to evaluate whether this heightened awareness increased palliative care consults among participating emergency medicine providers. Methods: We conducted an anonymous convenience sample survey and two educational interventions about HPM including the surprise question among emergency medicine resident and attending physicians at a large urban public academic quaternary care center from July to November 2018. A report of palliative care consults ordered between August 1, 2017 and January 1, 2019 was generated from the electronic health records used by the hospital. The number of palliative care consults made before and after the educational intervention was compared. Results: After the first educational intervention centered on the surprise question, palliative care consults from the ED increased from an average of 2.25 per month (range 0 to 8, SD: 2.38) to 12.67 per month (range 9 to 19, SD: 4.01, p < .001). Conclusion: Educating EM physicians about the surprise question can increase the number of palliative care consults from the ED, thereby potentially improving patient care and decreasing costs by avoiding unwanted healthcare interventions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
