--- The aim of this study was to determine the antibacterial activity of the essential oil of Luma chequen (Molina) A. Gray “myrtle“ against Streptococcus mutans. The disk-diffusion method in agar was used. The strain was reactivated in Trypticase Soy agar plate (TSA), incubated at 37 °C for 24 hours in microaerophilic. 5 colonies were picked and transferred to a test tube with 5 mL of Mueller-Hinton broth, incubated at 37 °C for 6 hours under microaerophilic conditions until a turbidity equivalent to 0.5 Mc Farland scale. Seeding was performed on 14 plates with Mueller-Hinton agar by diffusion technique, using the essential oil in concentrations of 10, 50 and 100%, and the incubation proceeded in microaerophilic at 37 ºC for 24 hours. Statistical analysis was performed using STATA Version 12 program. Concentrations of 10, 50 and 100 % had a halo of inhibition average of 6.28, 7.88 and 8.66 mm respectively, the mean difference between these three concentrations showed statistically significant difference (P<0.05). We conclude that the three concentrations of the essential oil of Luma chequen (Molina) A. Gray “myrtle“, exhibit antibacterial activity against Streptococcus mutans. Keywords: Streptococcus mutans, myrtle, antibacterial activity.
