    Summary

    This study evaluated microleakage in composite resin restorations with different cement linings. Glass ionomer cement significantly reduced cervical microleakage, indicating its effectiveness in sealing tooth preparations.

    Area of Science:

    • Dentistry
    • Dental Materials Science

    Background:

    • Class II composite resin restorations are prone to microleakage.
    • Various cement linings are used to improve marginal integrity.
    • Understanding microleakage is crucial for restoration longevity.

    Purpose of the Study:

    • To evaluate microleakage in extensive class II preparations.
    • To compare the efficacy of different cement linings (calcium hydroxide, polycarboxylate cement, glass ionomer cement) with composite resin restorations.
    • To assess the impact of thermal cycling on microleakage.

    Main Methods:

    • Extracted human third molars with class II preparations were restored using composite resin (Visio-Molar) and bonding resin (Visio-Bond).
    • Teeth were restored with one of three cement linings: Ca(OH)2, polycarboxylate cement, or glass ionomer cement.
    • Restored teeth underwent either thermal cycling (5-55°C for 24h) or storage in distilled water (37°C for 24h).
    • Microleakage was assessed using fluorescein dye penetration and quantified with an optical incident fluorescein microscope.

    Main Results:

    • Microleakage was present at the cervical wall in all tested restorations.
    • Thermal cycling did not significantly affect marginal microleakage.
    • Glass ionomer cement lining significantly reduced cervical marginal leakage (p < 0.001).

    Conclusions:

    • Glass ionomer cement is a superior lining material for reducing cervical microleakage in class II composite restorations.
    • Composite resin restorations, even with linings, exhibit cervical microleakage.
    • Further research may explore other lining materials or restorative techniques to minimize microleakage.
