In-vitro evaluation of bond strength of four self-etching cements.

Unlabelled: Indirect restorations need to be attached with adhesive luting agents to prevent them from becoming dislodged and provide adequate marginal sealing. The aim of this study was to evaluate bond strength to dentin of self-etching resin cements.

Materials And Methods: 75 flat dentin surfaces were randomly distributed among 5 groups, according to cements used; Group 1: RelyxU100 (3M/ESPE), Group 2: Bis Cem (Bisco), Group 3: Max Cem (Kerr), Group 4: SeT PP (SDI) and Group 5: Relyx ARC (3M/ESPE), control.
