Original Scientific Article



To assess and compare the microleakage extent between preformed metal crowns (PMCs), preveneered PMCs and zirconia crowns using different adhesive luting cements.


Thirty-six primary first molars were divided into three groups (n = 12) each prepared to receive different crowns (PMCs, preveneered PMCs, or zirconia crowns). Each group was further sub-grouped (n = 4) according to the luting cement (resin cement, resin modified glass ionomer cement, or glass ionomer cement). After cementation, the teeth were thermocycled, placed in 0.5% basic fuchsin, and sectioned to assess dye penetration. The results were analysed using ANOVA and Bonferroni statistical tests. The level of significance was set at p < 0.05.


The microleakage recorded in zirconia crowns was significantly worse than that in preveneered PMCs and PMCs (p < 0.001). Regardless of the crown type, resin cement resulted in the least microleakage with statistically significant differences from glass ionomer cement (p < 0.05).


As far as microleakage is concerned, preveneered PMCs seem to be an aesthetic and suitable alternative to PMCs. In addition, resin cement stands to be the most optimum luting cement.
