    The purpose of this study was to determine the inhibitory effect of 2% chlorhexidine on metalloproteinases in the adhesive system of composite resins: an in vitro study. The study used an experimental, quantitative, and analytical design. A formula for independent samples in mean differences was applied, with 15 specimens per group. Additionally, the application of 2% chlorhexidine in dentin bonding was evaluated in terms of tensile strength. The technique used was observation, and data were recorded through a data collection sheet. Calibration of the certified universal testing machine was performed. In the results, it was observed that the average tensile strength for the Adper Single Bond 2-3M adhesive without 2% chlorhexidine was 8.7660, while for the Optibond Universal adhesive without 2% chlorhexidine, it was 10.5553. The average tensile strength for Adper Single Bond 2-3M with 2% chlorhexidine was 10.0707, while for Optibond Universal with 2% chlorhexidine, the average tensile strength was 12.8520. The results of the T-test show that, for both adhesive brands, the average strength was higher when 2% chlorhexidine was used compared to the absence of chlorhexidine, with this difference being statistically significant. It is concluded that there is a significant inhibitory effect of 2% chlorhexidine on metalloproteinases in the adhesive system of composite resins: an in vitro study.
