Abstract
lntroduction: The present article is a comparative in vitro study of the sealing ability of bonded amalgams versus glass-ionomer modified composite resins and composite resin restorations. Materials and method: 175 human molars were connected to a simulated pressure system (32 cm of distilled water). The hydraulic conductance (μL *min/mm²) of each sample was determined after being restored with each one of the different materials tested. Results: Results show less residual hydraulic conductance in samples restored with bonded amalgam than in samples with the rest of materials tested, specially with F2000 and Dyract. Conclusions: In those samples restored with bonded amalgam permeability is reduced to a higher extent than in samples restored with resin modified glass-ionomers. None of materials stopped filtration through dentin completely.
