摘要: Abstract Titanium tetrafluoride (TiF4) in an aqueous solution can decrease dentin permeability, but some effects of its incorporation into adhesive systems are not yet known. Therefore, the aim this study was to characterize physicochemical, water sorption (WS) and solubility (SL) properties two (Clearfil SE Bond/C Scotchbond Universal/S) incorporated with 0.0% (T0), 2.5% (T2) 4.0% (T4) titanium (TiF4), determine permeability (L) after application these both immediately afterwards (baseline) 6 months storage. The physicochemical analyses solutions were performed based on evaluating particle size (PS), polydispersity index (PDI) by dynamic light scattering, zeta potential (ZP) electrophoresis. WS SL tests followed ISO 4049 standards, used a 7-day storage period. L test analyzing human discs before system application, PS PDI higher for CT0 ST4 (p
