Resin-dentin bond stability and physical characterization of a two-step self-etching adhesive system associated with TiF4
•Long-term bond strength was not influenced by TiF4 in aqueous or primer solution and concentrations.•Bond strength values to superficial bond were higher than values to deep dentin.•Premature failures were more frequent with the use of 4% TiF4 in aqueous solution.•Aqueous solution of 2.5% and 4% Ti...

| description | •Long-term bond strength was not influenced by TiF4 in aqueous or primer solution and concentrations.•Bond strength values to superficial bond were higher than values to deep dentin.•Premature failures were more frequent with the use of 4% TiF4 in aqueous solution.•Aqueous solution of 2.5% and 4% TiF4 showed a trend towards agglomeration over time.•TiF4 incorporated into the primer presented an excellent stability, especially at 2.5%.
To evaluate the bond strength to superficial (SD) and deep (DD) dentin after the use of 2.5% (T2.5%) or 4% (T4%) titanium tetrafluoride (TiF4) in aqueous solution as a dentin pretreatment, or when incorporated into the primer (T2.5%P and T4%P) of an adhesive system (Clearfil SE Bond/CL). Degree of conversion (DC), particle size (PS), polydispersity index (PI) and zeta potential (ZP) of the solutions were evaluated.
Fifty molars were sectioned longitudinally to obtain two slices of each tooth, which were demarcated into SD and DD. Treatments were applied (n=10): CL; T2.5%; T4%; T2.5%P; T4%P. After 24h or 180days storage, microshear bond strength tests were performed. The DC values of T2.5%P and T4%P were evaluated by FTIR. PS, PI and ZP were measured using dynamic light scattering.
Analysis of mixed models showed significant effect of concentration of TiF4 * solution * storage time (p=0.0075). There were higher bond strength values in SD than in DD (p=0.0105) for all treatments in both times. The failure mode showed adhesive failures in the majority of groups, irrespective of depth and time (p=0.3746). The bond strength values were not affected by treatments. Lower average particle size was observed for T2.5%P and T4%P at baseline. T2.5% and T4% showed a trend towards agglomeration.
Higher bond strength values were achieved at SD for all treatments and times. The failure modes observed were adhesive. TiF4 incorporation did not affect DC. T2.5%P and T4%P presented excellent stability over time. |
