Objective: The aim of this study was to quantify the marginal leakage of
two glass-ionomer cements using spectrophotometer. Method and materials:
Standardized class V cavities were prepared on 60 extracted human maxillary
permanent first premolars, randomly assigned to two groups of 30 teeth each,
group A and group B. Group A was restored with Zirconomer and group B was
restored with GC Fuji IX Extra. Teeth were subjected to thermocycling and
stained with methylene blue. The microleakage was quantified
spectrophotometrically and the data were statistically analyzed with Student t
test. Results: Restorations of both the materials showed some microeakage in
Class V cavities and there were no significant differences statistically.
Conclusion: The sealing ability of GC Fuji IX Extra was much better than
Zirconomer and GC Fuji IX Extra exhibit better shade matching compared to
Zirconomer at cervical area of the teeth. - See more at:
