dc.descriptionTo evaluate physical-chemical properties of experimental diacetate chlorhexidine (CHX)-added resin blends. Methods: Blends were formulated: G1) TEGDMA; G2) TEGDMA/0.1% CHX; G3) TEGDMA/0.2% CHX; G4) TEGDMA/UDMA; G5) TEGDMA/UDMA/0.1% CHX; G6) TEGDMA/UDMA/0.2% CHX; G7) TEGDMA/BisEMA, G8) TEGDMA/BisEMA/0.1% CHX; G9) TEGDMA/BisEMA/0.2% CHX. Icon (R) was the control group. For sorption/solubility (SS), cylindrical specimens (n = 5) were prepared and their weight obtained. The specimens were immersed in deionized water for 7 days at 37 degrees C and their weight was verified again. SS were calculated using accepted formulas. For softening, cylindrical specimens (n = 10) were prepared and initial Knoop hardness number (KHN) obtained. The specimens were immersed in absolute ethanol for 24 h at 37 degrees C and final KHN accomplished. Softening values were calculated by KHN reduction percentage. For elastic modulus (EM) and flexural strength (FS) bar specimens were prepared (n = 10) and values obtained with a universal device (three point, 5 mm distance, 0.5 mm/min, load of 50 N). The data was analyzed using one-way ANOVA and Tukey test (alpha = 5%). Results: TEGDMA/BisEMA blends and Icon (R) showed the lowest sorption from blends (p > 0.05), and Icon (R) was the most soluble material (p < 0.01). TEGDMA/UDMA/0.1% CHX showed the highest softening, similar to Icon (R) (p > 0.05). For EM, all blends were different than Icon (R) (p < 0.01). For FS, TEGDMA blends were similar to Icon (R), showing the lowest averages (p > 0.05). Conclusions: Monomers chemical characteristics influenced the physical-chemical properties of experimental blends more than CHX. Between the blends tested, UDMA blends presented satisfactory results for assays evaluated. Clinical significance: Infiltrants CHX-added could arrest and reinforce initial caries lesions, and the antimicrobial effect could prevent new lesions in sound enamel adjacent to the infiltrated area.
