Abstract
We hypothesized that chlorhexidine would not negatively affect the immediate bond strength.
Root canals of eighty human extracted third molars were prepared for post cementation with each post systems' own burs. Four commercially available FRC posts (Glassix, D.T.Light-Post, Unicore, everStickPOST)...

Abstract
This study aimed to determine the influence of sodium hypochlorite (NaOCl) contamination on the microhardness of build-up composites. Fifty-two samples, from each of three build-up materials (LuxaCore Dual, MultiCore flow and Rebilda DC) were prepared. Half of the samples from each material were sto...

Abstract
During the 0- to 4-, 4- to 24-, and 24- to 48-hour intervals after treatment, the pain experience with the negative apical pressure device was significantly lower than when using the needle irrigation (p < 0.0001 [4, 24, 48 hours]). Between 0 and 4 and 4 and 24 hours, the intake of analgesics was si...

Abstract
The results showed no statistically significant difference in canal or isthmus cleanliness among the 4 groups, but there was a statistically significant difference (P < .001) in canal cleanliness between the 1-mm level versus the 3-mm and 5-mm levels for all of the groups.

Abstract
Very high levels of root canal cleanliness (< or = score 3) were found for each test group with activation. For the middle and apical third, the no-activation group was significantly less effective than the three other activation groups (p < 0.05). The manual-dynamic activation group (final rinse 17...

There was no significant difference between EDTA and maleic acid in the reduction of microhardness. The increase in roughness was significantly greater with maleic acid when compared with EDTA. CONCLUSION: Maleic acid reduced the microhardness of root dentin similar to EDTA but increased the surface...

Abstract
Oscillation of the ultrasonically driven file toward the groove is more effective in removing dentin debris from the groove than oscillation perpendicular to the groove, which can be related to the fact that there is a high-velocity jet from the file tip in a single direction following the file osci...
