| Summary: | Introduction: Marginal integrity of adhesive restorative materials
provides better sealing ability for enamel and dentin and plays
an important role in success of restoration in Class V cavities.
Restorative material with good marginal adaptation improves
the longevity of restorations.
Aim: Aim of this study was to evaluate microleakage in Class V
cavities which were restored with Resin Modified Glass Ionomer
Cement (RMGIC), Giomer and Nano-Ionomer.
Materials and Methods: This in-vitro study was performed
on 60 human maxillary and mandibular premolars which were
extracted for orthodontic reasons. A standard wedge shaped
defect was prepared on the buccal surfaces of teeth with the
gingival margin placed near Cemento Enamel Junction (CEJ).
Teeth were divided into three groups of 20 each and restored
with RMGIC, Giomer and Nano-Ionomer and were subjected to
thermocycling. Teeth were then immersed in 0.5% Rhodamine
B dye for 48 hours. They were sectioned longitudinally from
the middle of cavity into mesial and distal parts. The sections
were observed under Confocal Laser Scanning Microscope
(CLSM) to evaluate microleakage. Depth of dye penetration was
measured in millimeters.
Statistical Analysis: The data was analysed using the Kruskal
Wallis test. Pair wise comparison was done with Mann Whitney
U Test. A p-value<0.05 is taken as statistically significant.
Results: Nano-Ionomer showed less microleakage which was
statistically significant when compared to Giomer (p=0.0050).
Statistically no significant difference was found between
Nano Ionomer and RMGIC (p=0.3550). There was statistically
significant difference between RMGIC and Giomer (p=0.0450).
Conclusion: Nano-Ionomer and RMGIC showed significantly
less leakage and better adaptation than Giomer and there was
no statistically significant difference between Nano-Ionomer
and RMGIC. |
