Summary

Bonding dental composites to dentin with one-step self-etch adhesives is challenging. Activating the adhesive improved composite bonding, but water from dentin created interfacial defects, impacting bond strength.

Area of Science:

  • Dental Materials Science
  • Adhesive Dentistry
  • Biomaterials

Background:

  • One-step self-etch adhesives often exhibit poor bonding to chemically-cured composites.
  • The role of ternary catalysts and other factors in this suboptimal coupling remains unclear.

Purpose of the Study:

  • To investigate factors influencing the bond strength between dentin, one-step self-etch adhesives, and chemically-cured composites.
  • To evaluate the effect of adhesive activation and composite curing modes on interfacial integrity.

Main Methods:

  • Utilized a one-step self-etch adhesive with a separately activated ternary catalyst.
  • Assessed microtensile bond strength using light-cured (LC), delayed light-activated (DL), and chemical-cured (CC) composite modes.
  • Examined silver tracer penetration via TEM to analyze interfacial defects.

Main Results:

  • Adhesive activation improved composite coupling to bonded composite in all modes, and to bonded dentin in LC mode.
  • Poor coupling was observed with unactivated adhesive in CC mode.
  • Water trees and blisters formed in the adhesive layer bonded to dentin, originating from dentin itself, and at interfaces in CC and DL modes.

Conclusions:

  • Adhesive activation is crucial for effective coupling, particularly with light-cured composites.
  • Water originating from dentin significantly compromises the adhesive interface integrity.
  • Interfacial defects, such as water blisters, are prevalent in dentin-bonded interfaces, especially with chemical or delayed light curing.
