Atraumatic Restorative Treatment (ART), a recently reported field dentistry technique, involves removal of carious debris using only hand instruments and placement of a glassionomer cement (GIC) restoration. While small ART‐GIC restorations are effective short‐term replacements for lost tooth form, many larger ART‐GIC restorations are defective after two years. Presently, resin‐modified GICs (R‐M GIC) are available which require no special activation equipment and handle easily in field settings. This study measured the com‐ pressive, tensile, and shear bond strengths to enamel and dentin of a conventional ART‐GIC (Fuji IX) and two R‐M GICs (Fuji Plus and Advance) at a powder‐to‐liquid ratio of 3.6:1. The compressive strengths of the GICs tested were significantly different. Fuji IX had the highest compressive strength, and Advance had the lowest strength (p < 0.05). The tensile strength of the R‐M GICs was greater than that of the ART‐GIC. Fuji Plus showed the highest shear bond strength to enamel and dentin and was significantly different from both Fuji IX and Advance. A clinical protocol is presented followed by case reports where the ART technique was used for management of acute caries in a modern dental setting.
