Background: To retain endodontically treated teeth, a post and core crown is necessary. The process of creating space for the post removes a significant amount of root canal filling, increasing the risk of microleakage. This study compares microleakage in treated teeth restored with cast post and cores using two different cements and irrigants.
Materials & Methods: This experimental study investigated the effects of different cement and irrigant combinations on cloudiness caused by Enterococcus faecalis. Six groups, each with eight maxillary central teeth, were examined. Groups 1 and 2 used glass ionomer (GI) cement and Panavia resin cement, respectively, with EDTA as the irrigant. Groups 3 and 4 used the same cements with sodium hypochlorite (NaOCl). Group 5 was the positive control, while group 6 was the negative control. Samples were placed in sterilized Brain-Heart Infusion (BHI) and injected with E. faecalis every three days for 60 days. The occurrence of cloudiness was recorded and analyzed using two-way ANOVA (α = 0.05).
Results. The results showed no significant difference in microleakage between the cements and irrigants. The interaction between cements and irrigants in the four groups was not significant in the degree of microleakage (P>0.05) Group 5 samples became cloudy within three days, whereas Group 6 samples remained clear throughout the study.
Conclusion: None of the cements and irrigants provided a complete coronal seal. However, GI cement showed less microleakage than Panavia resin cement. NaOCl showed less microleakage than EDTA. However, the differences were not significant in cements and irrigants.
