REMINERALIZATION ABILITY OF FLUORIDE VARNISH CONTAINING TRICALCIUM
PHOSPHATE BY TIME
Objectives
: The aim of this study was to evaluate the degree of remineralization over time after application of fluoride varnish with
and without tricalcium phosphate (TCP).
Methods
: This in vitro study used extracted bovine lateral incisors without dental caries. Artificial lesions were created in the
enamel specimens. The amount of mineral loss (ΔFbefore) was measured using quantitative light-induced fluorescence (QLF).
Test fluoride varnishes (10 mg) were applied to the enamel surface of the specimen and dried for 4 min. No fluoride varnish
was applied to the specimens in the control group. Each group was randomly assigned 12 specimens, and remineralization was
allowed to occur to different time points (0.5, 1, 3, 6, 12, and 24 h) in each group. Specimens were washed with distilled water and
dried with compressed air for 3 s. ΔFafter was determined using QLF.
Results
: When fluoride varnish containing TCP was applied for up to 6 h, the amount of mineral loss significantly increased, and
when non-TCP fluoride varnish was applied for up to 12 hours, the amount of mineral loss significantly increased ( P <0.05).
However, the amount of mineral loss was higher in the control group. The difference between ΔFbefore and ΔFafter (ΔΔF)
increased over time. There was a significant difference between the TCP group and the control group after 6 h. The non-TCP
group showed a significant difference after 24 h compared to the control group. After 12 h, significant differences were observed
in the TCP group compared to both the non-TCP and control groups.
Conclusions
:This study showed that the degree of remineralization increased gradually over time after fluoride varnish application
compared to the control group. In particular, fluoride varnish containing TCP showed better remineralization capability than
varnish without TCP.
