Introduction:
Microleakage is an important consideration in primary dentition because the floor of the cavity preparation may be close to the pulp. The added insult to the pulp caused by seepage of irritants around the restoration and through the thin dentin may produce irreversible pulp damage.
Aim:
The objective of this study was to evaluate and compare the sealing ability of three light cured (LC) resin-modified glass-ionomer cements (RMGICs) in primary anterior teeth.
Materials And Methods:
Class V cavity was prepared on the labial surface of extracted primary anterior teeth which were then grouped and restored with Ketac N100, Fuji II LC, or Vitremer. Dye penetration test with methylene blue stain was used to record the microleakage. Depth of dye penetration was recorded in millimeters at the incisal and gingival margin using computer software.
Results:
The depth of dye penetration at the incisal margin in the three groups was comparable, but at the gingival margin, Vitremer showed the least dye penetration, followed by Fuji II LC, and Ketac N100. The depth of dye penetration at the gingival margin was higher than the incisal margins in all the three groups.
Conclusion:
Among the three RMGICs, Vitremer can be considered as the material of choice for restoring class V cavities in primary anterior teeth. Periodic recall and recare is necessary when any of the three materials are used in clinical practice.
