| description | Introduction: Glass ionomer cement (GIC) has best suited
paediatric dentists and is well recognised in the preventive
era of dentistry. However its use is affected by its inferior
mechanical properties. Hydroxyapatite whiskers have been
lately introduced as strengthening additive without affecting its
fluoride releasing property, but literature lacks data related to its
effect on recharging ability of glass ionomer cement.
Aim: To evaluate and compare fluoride release from
hydroxyapatite incorporated glass ionomer cement following
recharging with low fluoride dentifrices.
Materials and Methods: An 8% Hydroxyapatite whiskers
were added to Conventional Glass ionomer powder and 40
specimens each of conventional and Hydroxyapatite Glass
ionomer cement were prepared using customised Teflon
mould (5mm x 2mm) and were suspended in deionised water.
Recharging of aged specimens was done using low fluoridated
dentifrices containing 500ppm fluoride, twice daily and water
was replenished every 24 hours. Fluoride release was analysed
daily for 7 days and then weekly till 21 days using Sension 4
pH/ion selective electrode. Data thus obtained was statistically
analysed by descriptive analysis followed by repeated measures
ANOVA.
Results: Significant (p<0.01) increase in fluoride release was
observed in both the materials following recharging regimen.
Recharge pattern of hydroxyapatite glass ionomer was found to
be similar to conventional glass ionomer cement.
Conclusion: Within the limitations of this study it can be evinced
that fluoride rechargability and re-release remains unaffected
by the addition of hydroxyapatite whiskers and hence proves
to be more acceptable additive to glass ionomer cement to
improve its mechanical properties widening its arena of usage
by clinicians. |
