| Summary: | Introduction: Fluoride plays a key role in prevention of dental
caries and is also an essential element for oral health promotion
both in children and adults.
Aim: The aim of the present study was to evaluate the effect
of surface coating (petroleum jelly, G-Coat Plus) on the fluoride
releasing property of conventional Glass Ionomer Cement (GIC)
and Zirconomer.
Materials and Methods: A total of 30 disk shaped brass mold
specimens (6±0.1mm in diameter and 2±0.1mm thickness) for
each test group were fabricated with conventional GIC (Group
A) and Zirconomer (Group B). These test groups were further
divided into three subgroups of 10 each. The unprotected
specimens act as control (Group A1 and B1), G-Coat Plus
specimens as (Group A2 and B2) and for the remaining
specimens petroleum jelly was applied (Group A3 and B3).
Fluoride ion concentration was measured with a combination
of fluoride ion specific electrode and ion analyzer for every 24
hours for 15 days. The data was statistically analyzed using
Kruskal Wallis and Mann-Whitney U test.
Results: The Group B released significantly more fluoride
than Group A. Among all the subgroups the greatest amount
of fluoride was released from Group B1, in the first 24 hours
followed by A1 and B2. The least was observed on 15th day with
Group B3 and A3.
Conclusion: Both the tested materials (GIC and Zirconomer)
used in the study exhibited fluoride release whether protected
or unprotected with surface coating. Though there was a
difference between the groups, the pattern of fluoride release
was similar and continuous throughout the study period i.e.,
first the initial burst followed by sustained release. The results
revealed Zirconomer released more fluoride and is comparable
to conventional GIC. |
