Evaluation of the Effect of Monomer Systems on the Softening of a Composite Resin
Perea-Lowery, Leila / Tolvanen, Mimmi / Vallittu, Pekka K.
Purpose: To measure the softening via swelling of a composite resin by evaluating its surface hardness after the application of four monomer systems.
Materials and Methods: A total of 40 specimens made of a hybrid composite resin were evaluated. Four monomer systems were used as surface-conditioning primers during five exposure times. Surface microhardness measurements (n = 8) were made after application of the monomer systems.
Results: In all exposure times, Scotchbond Universal showed the highest influence on the composite resin surface softening (P < .05), followed by Stick Resin (P < .05).
Conclusion: Surface softening of composite resins might be achieved with monomer systems, especially with Scotchbond Universal, which may have a positive influence when repairing aged composite resin restorations.
