| description | Background:To investigate the effects
of final irrigation protocols with tannic acid (TA) on dentin microhardness and
push-out bond strength of an epoxy resin based sealer to root canal dentin.Methods: The 50 root halves were embedded in an acrylic resin for the
microhardness measurement. After
the initial baseline microhardness measurement, the root halves were randomly
divided into 5 groups according to the final irrigation protocol used (n=10): distilled water (control), 10% TA for 2 min, 10% TA for 5 min, 20% TA for
2 min, and 20% TA for 5 min.
After surface treatment, dentin microhardness values were recorded at close
proximity to the initial indentation areas.
For push-out bond strength test the root canals of 75
single-rooted mandibular premolars were instrumented and the final irrigation protocols
were applied as described above (n = 15). Following
root canal obturation with single cone technique using matched-taper gutta percha cones and
an
AH Plus- epoxy resin based root canal sealer, 1 mm-thick slices were obtained from the
middle third of the root canals. Push-out
bond strength test was applied. The data were analyzed using One way ANOVA and
Tukey HSD tests (p=0.05).Results:In TA-treated groups, there was a
significant increase in the microhardness values compared with the control
group (p<0.05). Regarding the push-out bond strength test, there was no significant
difference between the bond strength values of 10% TA for 2 min and the control
group (p>0.05). The remaining groups presented higher bond strength values
than the control group (p<0.05).Conclusions: TA increased dentin microhardness and the
bond strength of the epoxy resin based sealer to root canal dentin. The effect
on the bond strength was time and concentration dependent. Keywords: bond strength, dentin, microhardness, epoxy resin based sealer, tannic
