    This study evaluated, determined, and compared the antibacterial effect of glass ionomers for ART restoration, both encapsulated (Riva Self Cure® and Equia Forte®) and powder-liquid (Fuji IX® and Ketac Molar Easymix®), against cultures of Streptococcus mutans (ATC 35668) and Lactobacillus acidophilus (ATC 4356). The methodology was experimental, quasi-experimental, in vitro, conducted in the Herrera S.A.C. Clinical Laboratory and medical offices. Forty Petri dishes were grouped into two groups according to the bacteria, inoculating the encapsulated and powder-liquid ionomers with bacterial strains using the diffusion technique. The data was collected by measuring the inhibition halos with a vernier and processed statistically. Results showed that the inhibition halos on Streptococcus mutans (ATC 35668) cultures formed by encapsulated glass ionomers were 9.4 + 2.11 mm for Riva Self Cure® and 9.0 + 2.16 mm for Equia Forte®. For powder-liquid ionomers, the halos were 8.9 + 1.66 mm for Ketac Molar Easymix® and 9.6 + 1.83 mm for Fuji IX®. Likewise, the mean inhibition halos on Lactobacillus acidophilus (ATC 4356) cultures obtained by the encapsulated glass ionomers were 9.3 + 1.76 mm for Riva Self Cure® and 9.6 + 2.5 mm for Equia Forte®. The halos obtained by powder-liquid ionomers were 8.9 + 1.1 mm for Ketac Molar Easymix® and 8.7 + 1.63 mm for Fuji IX®. Conclusion: There is in vitro antibacterial activity of glass ionomers (Riva Self Cure® and Equia Forte®) and powder-liquid (Fuji IX® and Ketac Molar Easymix®) for ART restoration against cultures of Streptococcus mutans (ATC 35668) and Lactobacillus acidophilus (ATC 4356).
