Description
Summary:1-Butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide (BMI.NTf<sub>2</sub>) is a hydrophobic ionic liquid with potential antibacterial properties for dental materials. This study aimed to (1) incorporate different mass fractions of BMI.NTf<sub>2</sub> into a dental adhesive and (2) assess its impact on physical and chemical properties. Adhesive resins were prepared with 1 (G<sub>1%</sub>), 2.5 (G<sub>2.5%</sub>), and 5 wt.% (G<sub>5%</sub>) BMI.NTf<sub>2</sub>, with a control group (G<sub>CTRL</sub>) lacking the ionic liquid. Evaluations included polymerization kinetics, degree of conversion (DC), softening in solvent (ΔKHN%), and ultimate tensile strength (UTS). Groups with BMI.NTf<sub>2</sub> showed accelerated polymerization kinetics, with G<sub>5%</sub> achieving a higher DC and ΔKHN% compared to G<sub>CTRL</sub> (<i>p</i> < 0.05). Lower concentrations (1% and 2.5%) did not affect ΔKHN%, and no significant differences were found in UTS across groups (<i>p</i> > 0.05). Notably, 2.5 wt.% of BMI.NTf<sub>2</sub> increased the DC without affecting other properties, indicating optimal polymerization rates and handling characteristics. These results support the development of BMI.NTf<sub>2</sub>-based antibacterial adhesives that may assist in preventing secondary caries in restorative dentistry.
