Summary

This study compared four dental bonding agents for amalgam restorations, finding no system completely prevented microleakage. Amalgambond Plus showed the most leakage, while Optibond Solo, Fuji Plus, and Prime & Bond 2.1 offered improved marginal seals.

Area of Science:

  • Dental Materials Science
  • Restorative Dentistry
  • Biomaterials

Background:

  • Microleakage at the tooth-restoration interface is a primary cause of secondary caries and restoration failure.
  • Effective marginal sealing is crucial for the longevity of amalgam restorations.
  • Evaluating new bonding systems is essential for improving clinical outcomes.

Purpose of the Study:

  • To compare the microleakage of Class V cavities lined with Amalgambond Plus with HPA, Optibond Solo, Fuji Plus, and Prime & Bond 2.1 before amalgam restoration.
  • To assess the effectiveness of these bonding systems in preventing marginal leakage.
  • To analyze the interface between the bonding agent, amalgam, and tooth structure using confocal laser scanning microscopy (CLSM).

Main Methods:

  • Class V cavities in human teeth were prepared and lined with four different bonding systems.

  • Restorations were completed using Logic amalgam.
  • Teeth underwent thermocycling in basic fuchsin dye, followed by sectioning and evaluation of dye penetration using CLSM.

    • Main Results:

    • No bonding system completely eliminated microleakage.
    • Significant differences in microleakage were observed between Amalgambond Plus with HPA and the other three systems (Prime & Bond 2.1, Fuji Plus, Optibond Solo) on both enamel and dentine.
    • Amalgambond Plus exhibited significantly more leakage on dentine, while Prime & Bond 2.1 showed more leakage on enamel. No significant differences were found among Prime & Bond 2.1, Fuji Plus, and Optibond Solo.
    • CLSM revealed variations in hybrid layer thickness, resin penetration into dentinal tubules, and resin incorporation into amalgam particles.

    Conclusions:

    • Amalgambond Plus with HPA demonstrated inferior marginal sealing compared to Optibond Solo, Fuji Plus, and Prime & Bond 2.1.
    • Optibond Solo, Fuji Plus, and Prime & Bond 2.1 are viable options for improving the marginal seal of amalgam restorations.
    • Further research may explore long-term clinical performance and different cavity preparations.
