title: [Performance and Compatibility of Self Polymerizing Prime and Bond NT Adhesive and the Composite LuxaCore].
abstract: OBJECTIVE
  To evaluate the performance of bond strength and the compatibility of Prime &Bond NT self etching adhesive resins without activator on dentin surface with dual composite resin LuxaCore, and verify the contribution of a coactivator.
  
  
  METHODS
  twenty-four human teeth without decay, molars or pre-molar are used. The dental crowning is cut with diamond disc mounted on a hand piece; the roof surface is flattened and well humidified. Each tooth is embedded in cold self-etching resin (Plexil Excil). Samples are divided into two groups of 12. in the first group, self-etching Prime &Bond NT resin adhesive without activator is supplied on the flat mesial dentin roots, then dual cure composite resin LuxaCore) is bonded. The second group was subject to the same treatment but with addition of co-activator the Prime &Bond NT self-etching adhesive resin. Debonding was achieved with Universal testing machine and mean shear bond strengths were determined for each test group. The data were subjected to ANOVA (p < 0001).
  
  
  RESULTS
  Bond strength obtained with self-etching Prime &Bond NT without activator is 10.635 MPa. With addition of activator it is 15.185 MPa
  
  
  CONCLUSIONS
  supplementing with an activator has significantly improved bonding strength.
