- Abstract
The aim of this study was to determine the effect of three storage solutions and two storage durations on microshear bond strength (μ SBS) of a resin composite. Sixty non-carious human permanent molars were stored in three storage solutions (0.1% thymol, 10% formalin, and distilled water). Each tooth was separated mesio-distally into two parts. Specimens of the first part were stored for 24 hours, while specimens of the second part were stored for two months in the solutions. After each storage period, the enamel surface was convered with a composite resin in combination with an etch-rinse adhesive system. Specimens were then serially sectioned into sticks of 1 mm2 bond area and subjected to μ SBS test. There were no statistically significant differences between the two storage periods for each solution (p>0.05). The thymol solution group showed lower μ SBS values than those of distilled water for both storage periods (p<0.05). As for the formalin group, its μ SBS values were not statistically different from those of distilled water and thymol groups at each storage period (p>0.05). In conclusion, the thymol solution caused the μ SBS of the resin composite to decrease when compared to both formalin and distilled water after 24 hours and two months. However, the μ SBS of the resin composite was not affected by storage duration.
