    Dental restorations for oral rehabilitation - testing of laboratory properties versus clinical performance for clinical decision making.

    Repairing old composite dental restorations is possible. Optimal re-bonding involves roughening the surface, water conditioning, and using a specific primer for improved strength.

    Area of Science:

    • Dental Materials Science
    • Biomaterials Engineering

    Background:

    • Posterior composite restorations degrade over time due to wear, discoloration, and staining.
    • Re-surfacing aged composites is a potential repair method.

    Purpose of the Study:

    • To investigate the bonding efficacy of new composite materials to aged composite substrates.
    • To evaluate the impact of various conditioning methods on re-bond strength.

    Main Methods:

    • Aged composite surfaces underwent mechanical (bur roughening), chemical, and primer conditioning.
    • New composite was bonded to conditioned aged surfaces.
    • Specimens were stored in artificial saliva and tested for shear bond strength.

    Main Results:

    • Optimal re-bond strengths reached 77-102% of original bulk shear strengths across four composite types.

  • The most effective conditioning involved D830 diamond bur roughening, water conditioning, and Scotchbond-1 primer.

    • Conclusions:

    • Effective re-surfacing of aged posterior composite restorations is achievable.
    • Specific mechanical and chemical conditioning protocols significantly enhance re-bond strength.
