Effect of aging on microleakage of restorative systems.
This study evaluated the sealing properties of AP.H/Prisma Universal Bond 3, Z100/Scotchbond MultiPurpose, AP.H/Imperva Bond, Charisma/Denthesive, Bisfil M/All-Bond 2, resin composite/dentin adhesive systems and Fuji II LC light-cured glass ionomer, in Class V preparations following 6 months of storage in a 37 degrees C water bath. The Class V preparations extended just beyond the cemento-enamel junction of extracted human molars. The restored teeth were placed in 37 degrees C water for 24 hours and then thermally stressed for 100 temperature cycles. Half of the specimens were tested for microleakage at this time. The other specimens were returned to water storage and thermally stressed every 30 days during the following 6 months and then assessed for microleakage by dye penetration. AP.H/Imperva Bond, Z100/Scotchbond Multi-Purpose and Fuji II LC were not affected by the storage, while AP.H/Prisma Universal Bond 3, Charisma/Denthesive and Bisfil M/All-Bond 2 revealed some increase in microleakage at the dentin/cememtum margin.
