TI  - The Effect of Different Adhesive Resins,
Composite Resins and Thermal Cycling on the
Repair Bond Strength of Bulkfill Composite Resin
AB  - Objective: This study evaluated the influence of different adhesives, composites
and thermal cycling on the repair bond strength of bulkfill composite.
Materials and Methods: A total of 54 bulkfill composite resin disks were obtained.
The samples were stored in distilled water for 14 days and then the sample’s surfaces
were air-abraded with Al2
O3 particles, etched with phosphoric acid, washed and
dried. An adhesive was applied to the samples after the silane application. The
samples were randomly divided into three main groups according to the type of
adhesive resin used (a self-cured universal adhesive, a total-etch adhesive and a
self-etch adhesive). After the adhesive application, four composite resin cylinders
were placed on the sample surface using three different repair composites (bulkfill
composite, microhybrid composite and nanohybrid composite). A total of 5000
thermal cycles were applied to half of the samples (n=12). A microshear bond
strength test was performed using a universal tester. The data obtained were
analyzed using Mann-Whitney U and Kruskal-Wallis tests.
Results: Of the repair composites, bulkfill composite tended to show the highest
bond strength. There was no significant difference between the microhybrid
and the nanohybrid composite groups (p>0.05). Generally, the adhesives did not
significantly affect the repair bond strength.
Conclusion: The use of bulkfill composite to repair bulkfill composite provides more
efficient repair bond strength. The tested adhesives can be used safely to repair
bulkfill composite. The repair bond strength was not negatively affected after 5000
thermal cycles.
