Can Modification with Urethane Derivatives or the Addition of an Anti-Hydrolysis Agent Influence the Hydrolytic Stability of Resin Dental Composite?
Abstract
Due to the questionable durability of dental restorations, there is a need to increase thelifetime of composite restoration. The present study used diethylene glycol monomethacrylate/4,40-methylenebis(cyclohexyl isocyanate) (DEGMMA/CHMDI), diethylene glycol monomethacrylate/isophorone diisocyanate (DEGMMA/IPDI) monomers, and bis(2,6-diisopropylphenyl)carbodiimide(CHINOX SA-1) as modifiers of a polymer matrix (40 wt% urethane dimethacrylate (UDMA), 40 wt%bisphenol A ethoxylateddimethacrylate (bis-EMA), and 20 wt% triethyleneglycol dimethacrylate(TEGDMA)). Flexural strength (FS), diametral tensile strength (DTS), hardness (HV), sorption, andsolubility were determined. To assess hydrolytic stability, the materials were tested before and aftertwo aging methods (I-7500 cycles, 5 ◦C and 55 ◦C, water and 7 days, 60 ◦C, 0.1 M NaOH; II-5 days,55 ◦C, water and 7 days, 60 ◦C, 0.1 M NaOH). The aging protocol resulted in no noticeable change(median values were the same as or higher than the control value) or a decrease in the DTS valuefrom 4 to 28%, and a decrease in the FS value by 2 to 14%. The hardness values after aging were morethan 60% lower than those of the controls. The used additives did not improve the initial (control)properties of the composite material. The addition of CHINOX SA-1 improved the hydrolytic stabilityof composites based on UDMA/bis-EMA/TEGDMA monomers, which could potentially extendthe service life of the modified material. Extended studies are needed to confirm the possible use ofCHINOX SA-1 as an antihydrolysis agent in dental composites
