| Sumario: | Introduction: Microleakage is an important property that has been
used in assessing the success of any restorative material used in
restoring a tooth. Immediate application of a surface coating agent
is suggested to protect glass ionomer cement against moisture
contamination and dehydration during early setting.
Aim: To compare marginal microleakage of two different Glass
Ionomer Cement (GIC)- Conventional GIC and Resin Modified GIC
in primary anterior teeth using three surface coating materials.
Materials and Methods: An in vitro study was conducted between
January 2014 to October 2017 on freshly extracted 40 anterior
primary teeth which were randomly assigned into two main groups
(Fuji II GIC and Fuji II LC GIC) with four subgroups (control-no
surface coating, A=GC Fují Varnish II, B=GC G-Coat Plus, C=Icon).
A standardised Class V cavity preparation was prepared on the
labial surface of each tooth. Specimens were coated with two
layers of nail varnish, leaving a 1 mm window around the cavity
margins and placed in a solution of Methylene blue Dye for 24 hour
at 37°C. The teeth were sectioned longitudinally in a buccolingual
direction of the restorations and evaluated under stereomicroscope
to check extent of dye penetration. The results were analysed by
ANOVA and Tukey’s post-hoc test (p≤0.05).
Results: It was found that maximum microleakage was seen
in group 1 (Fuji II GIC) as compared to group 2 (Fuji II LC GIC)
and it was non-significant (p=0.53). Ascending order for mean
microleakage for Group 1 was as follows: Control >GC Fuji
Varnish >Icon DMG >GC G-Coat and for Group 2: Control >GC
Fuji Varnish >Icon DMG >GC G-Coat. Icon when compared
with Gc coat and Varnish also showed non-significant (p=0.137)
difference in Group 2.
Conclusion: All three different surface coatings can seal glass
ionomer restorations. The GC G-Coat Plus has the least
microleakage on Resin-Modified GIC (RMGIC) compared to the
other surface coatings. This would aid the clinicians to make
appropriate decision regarding the choice of material to be used
for restoration and coating in anterior primary teeth. |
