Microleakage of adhesively bonded cervical amalgam restorations
MetadataShow full item record
ABSTRACT: Purpose: To evaluate dye penetration in adhesively bonded cervical amalgam restorations. Materials and Methods: The specimens were randomly divided into four groups and the adhesives Prime & Bond 2.1, Prime & Bond 2.1 Dual Cure, Scotchbond Multi Purpose Plus and Amalgambond Plus were tested. After being restored and polished, the teeth were thermocycled 1,000 times at temperatures varying between 5°C ± 2°C and 55°C ± 2°C. Statistical analysis was carried out using the Kruskal-Wallis test and multiple comparisons. Results: Scotchbond Multi-Purpose Plus demonstrated lower levels of microleakage in enamel and dentin. The dual adhesives were more effective than the one bottle adhesive.
