Table 2. Prevalence of microleakage.
Figure 2. IRM group showed mean leakage of 6.38%.
Figure 3. Mean leakage for Coltosol group was 4.85%.
Figure 4. Vidrion R group showed mean leakage of 32.2%, which was significantly different from the other groups.
Figure 5. Scotch Bond showed the poor sealing ability. The mean leakage was 54.35%, which did not differ significantly from the positive control group.
Figure 6. Control group showed mean leakage of 62.07%.
