Influence of dentin pretreatment with titanium tetrafluoride and self-etching adhesive systems on microtensile bond strength.

Abstract

Two-way ANOVA and Tukey's test demonstrated that pretreatment of dentin with a TiF4 solution did not affect the microTBS values of either of the adhesive systems (P = 0.675). CLEAR provided higher bond strength than ADP, regardless of whether dentin was or was not pretreated with the TiF4 solution. Failure mode showed mostly adhesive failures in all groups, except when only ADP was used, causing mostly cohesive fractures in resin.
