Comparison of Microleakage of Pedo Jacket Crowns and Stainless Steel Crowns Cemented With Different Cements
Objectives: This study aimed to assess the microleakage of Pedo Jacket crowns compared to stainless steel crowns (SSCs) cemented with different cements.
Materials and Methods: In this in vitro experimental study, 80 primary molars were randomly divided into four groups of 20. Groups 1 and 2 were subjected to standard tooth preparation for SSC. Crowns in group 1 were cemented with glass ionomer (GI) and crowns in group 2 were cemented with resin modified glass ionomer (RMGI) cement. In groups 3 and 4, minimal tooth preparation was performed for Pedo Jacket crowns, and the crowns were cemented with RMGI and Panavia resin cement, respectively. Microleakage was measured in mesial and distal surfaces in micrometers, and the mean value for each tooth was calculated. One-way ANOVA was applied to compare the microleakage of the four groups.
Results: Group 3 (Pedo Jacket cemented with RMGI) showed the highest microleakage (1523.83±250.32 µm) with significant differences with the remaining three groups (P<0.001). Microleakage in group 4 (Pedo Jacket cemented with Panavia) was significantly lower than that in the other three groups (301.25±219.53 µm, P<0.001). Groups 1 (SSCs cemented with GI) and 2 (SSCs cemented with RMGI) were not significantly different in terms of microleakage (P=0.49), although group 1 showed slightly higher microleakage than group 2 (598.43±260.85 µm versus 500.25±124.74 µm).
Conclusion: Pedo Jacket crowns can serve as an acceptable esthetic alternative to SSCs if cemented with resin cement.
