Prelude Total-Etch is supplied with phosphoric acid etchant, omitting the self-etching primer. The dentin adhesion strength of Prelude using phosphoric ethcant is about the same as with the self-etching primer. The enamel adhesion strength is improved with use of the phosphoric etchant. However use of self-etching primer is a less technique sensitive procedure. It is well known that self-etching primers rarely result in post operative sensitivity to bite pressure. Prelude is extremely forgiving in the presence of moisture. Too wet, or too dry is not a concern. Its water/ethanol formulation tolerates an environment that would adversely affect other products. The remarkably low 5 micron film thickness means fit is not affected and it will not present a radiolucent layer. Bond strengths to cut and un-cut enamel are extremely high.
