ABSTRACT


Aim

The purpose of this study was to determine the wear of stainless steel crowns (SSCs) in children, and
compare the extent of microleakage in SSCs that had been repaired using either a cermet glass-ionomer cement (GIC) or a
packable composite resin (CR).

Methods

For the first aim, the occlusal surface thickness of 31 harvested
SSCs (21 primary first and 10 second molars) and 18 unused SSCs was measured, and then examined under scanning
electron microscopy. For the second aim, standardised holes were prepared on the occlusal surfaces of 20 SSCs, and then
repaired using either a cermet GIC or packable CR. After their repair, the extent of microleakage was determined using
0.5 basic fuchsin and stereomicroscopy.

Results

The thickness of all the harvested SCCs was 5.3 m less
than that of the unused SCCs (p<0.02), and there were no significant differences between the thickness and occlusal wear rates of harvested SSCs from the first and second primary molars. Although neither of the two repair materials completely prevented microleakage, the number of specimens in which microleakage occurred after repair with a cermet GIC was significantly lower than the number of specimens in which a packable CR was used (p<0.05).

Conclusion

We
concluded that the occlusal surfaces of SSCs for first and second primary molars display wear. Although perforated SSCs
can be repaired using either a cermet GIC or a packable CR, less microleakage occurs in SSCs that were repaired with a
cermet GIC than those with a packable CR.
