Tiivistelmä
The objective was to evaluate effect of dimethyl sulfoxide (DMSO) on microtensile bond strength (WITS) and nanoleakage (NL). Superficial dentin was acid-etched and pretreated with DMSO. Etch-and-rinse adhesive was applied and restored with resin composite incrementally. After 24 h, teeth were sectioned, stored in artificial saliva for 24-h or 6-months before mu TBS evaluation. Failure modes were examined. Six beams per group were submitted to nanoleakage evaluation using SEM. Data were analyzed using ANOVA and Tukey's test (alpha=0.05). Pretreatment had no significant effect on mu TBS after 24 h (p>0.05). After 6 months storage, mu TBS of control decreased significantly, more than with the groups treated with 0.01% or higher (p<0.05). DMSO-pretreated groups preserved mu TBS in all groups. After 6-months, all groups except 0.001% showed significantly lower nanoleakege compared to control (p<0.05). DMSO (0.01-20%) may improve the hybrid layer integrity and bonding durability. The best results were seen with low (1-5%) of DMSO concentrations.
