Aims (Purpose): The study’s aim was to investigate the effect of colloidal dispersion of titanium dioxide (TiO2) nanoparticles at 4% by mass on the long-term water sorption and solubility of two commercial universal bonding agents. Settings and Design: An in vitro study.
Methods and Material: A colloidal dispersion of TiO2 nanoparticles was prepared and incorporated into two commercial dental bonding agents, that is, Ambar Universal (FGM, Brasil) and G-Premio Bond Universal (GC, America) at 4% by mass. Forty bonding agents discs were prepared and divided into four groups of 10 discs each, that is, GA: Ambar Universal (control), GB: Ambar Universal (4% TiO2 incorporated), GC: GPremio Bond universal (control), and GD: G-Premio Bond (4% TiO2 incorporated). The discs were prepared by dispensing the bonding agents into a silicone mold of 5 mm diameter and 1 mm depth. After the discs’ desiccation, the cured discs were weighed and stored in distilled water to be evaluated for water sorption and solubility over 1-year storage period.
Statistical analysis used: Statistical analysis was performed by independent variable t-test performed using the IBM-SPSS software.
Results: The incorporated bonding agents groups (GB and GD) showed significantly lower (P < 0.05) water sorption and solubility after 1 year of water storage in comparison to the control bonding agents. Both GC and GD showed significantly lower water sorption and solubility than GA and GB.

Conclusions: Incorporation of the colloidal dispersion of TiO2 nanoparticles at 4% by mass into the universal bonding agents significantly reduced their water sorption and solubility in comparison to their control groups.
