    This research study was conducted in vitro with the objective of comparing the antibacterial activity of essential oils from Schinus molle L. (molle) and Thymus vulgaris (thyme) with 0.12% chlorhexidine gluconate against Porphyromonas gingivalis. This experimental study was carried out at the National University of San Marcos in the Microbiology Laboratory of the Faculty of Dentistry. The sample consisted of 40 Petri dishes where the essential oils Thymus vulgaris at 100% and 50%, Schinus molle L. at 100% and 50% were used, compared with 0.12% chlorhexidine gluconate, and dimethyl sulfoxide (DMSO) as a negative control. The disk diffusion method was used, and the dishes were incubated for 15 days at 37°C. The inhibition halos were measured only once at the time of measurement. Data analysis was processed using the Scheffé's Post Hoc statistical test. The results showed that, of the two oils, thyme had the greatest effect on Porphyromonas gingivalis, while molle had the least effect. Both thyme and molle essential oils exhibited greater antibacterial activity than 0.12% chlorhexidine gluconate.
