Abstract
A range of dental varnishes containing several calcium and phosphate
compounds in addition to fluoride to promote remineralization have recently been
commercialized. However, the fluoride varnish in the presence of calcium and
phosphate can react to form relative poorly soluble phases and its bioavailability.
Most of previous studies have focused on fluoride release over a short period. The
purpose of this in vitro study was to evaluate the fluoride release from different
fluoride varnishes on primary teeth during 3 months. Twenty-five sound primary
incisors were randomly divided into five groups: Group A-control group (no
treatment), Group B - 5% sodium fluoride varnish (5%NaF)(Duraphat®), Group
C-5% sodium fluoride plus tricalcium phosphate varnish (5%NaF+TCP)(ClinproTM
White), Group D- 5% sodium fluoride plus amorphous calcium phosphate varnish
(5%NaF+ACP)(Enamel Pro®), and Group E-5% sodium fluoride plus tricalcium
phosphate varnish (5%NaF+TCP)(Mahidol). The samples were then immersed
in artificial saliva at room temperature until used. The concentration of fluoride
released was measured with F-ion-specific electrode at 2, 4, 8, 12, 24, and 48 hours
and then weekly for three months...
