A 3-month study of fluoride release from different calcium phosphate fluoride varnishes on primary teeth.

A 3-MONTH STUDY OF FLUORIDE RELEASE FROM DIFFERENT CALCIUM PHOSPHATE FLUORIDE VARNISHES ON PRIMARY TEETH. Southeast Asian J Trop Med Public Health. 2016 Sep;47(5):1098-104 Authors: Rirattanapong P, Vongsavan K, Saengsirinavin C, Jantarakam N 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...
