Variables influencing the repair strength of dental composites.

摘要: Differences in the flexural strength of composites (P-30) repaired with four different adhesive techniques were determined and compared to unrepaired specimens. Besides investigating effects differences repair methods, both effect composite age at time water storage on evaluated. No significant found between specimens which had been stored for times (1 or 60 days) before they repaired. All specimens, including ones, became weaker water. After 90 360 days 37 degrees C water, ranged 25 50% The weakest group was one after acid etching, rinsing, air drying only.
