This work is a literature review on the use of Glass Ionomer Cement (GIC) for Atraumatic Restorative Treatment (ART) of elderly patients. The research was conducted online, using available academic database platforms, such as a PubMed. It was concluded that the ART is an adequate treatment approach for caries in elderly patients. It presents similar efficiency to the conventional treatment and advantages, such as biocompatibility, anticariogenic action, simplicity, no anesthesia or rotary equipment. Furthermore, it is both cost and time effective while more teeth can be treated per session. However, clinical evidence on the technique being applied to elderly patients is still relatively scarce.
