Summary

Repairing posterior composite fillings is crucial as their use grows. Dentin bonding agents offer superior bond strength for posterior composite repairs compared to enamel bonding agents.

Area of Science:

  • Dental Materials Science
  • Restorative Dentistry

Background:

  • Posterior composite restorations are increasingly used as an alternative to amalgam.
  • The rising prevalence of composite use necessitates effective repair strategies for aged restorations.

Purpose of the Study:

  • To evaluate the bond strength of repaired posterior composite restorations using various bonding agent/composite combinations.
  • To compare the bond strength of different repair systems to aged posterior composite substrates.

Main Methods:

  • Aged posterior composite substrates were prepared.
  • Repairs were performed using different dentin bonding agent/composite pairs and enamel bonding agent/composite pairs.
  • The bond strength of the repaired specimens was measured and compared.

Main Results:

  • Dentin bonding agent/composite pairs demonstrated the highest bond strengths.
  • The bond strength achieved with dentin bonding agents exceeded that of resin bonded to etched enamel.
  • Enamel bonding agent/composite repairs yielded the lowest bond strengths, falling below resin/etched enamel bond strengths.

Conclusions:

  • Dentin bonding agents are effective for repairing aged posterior composite restorations, providing superior bond strength.
  • Enamel bonding agents are less suitable for posterior composite repairs, resulting in weaker bonds.
  • The choice of bonding agent significantly impacts the success of posterior composite repair.
