ABSTRACT
OBJECTIVE:
This study was performed to investigate the effects of external tooth bleaching with flouridation on the appearance of white spot lesions (WSLs) in vitro.METHODS:
In total, 125 bracket-bonded bovine incisor enamel blocks with artificial WSLs were randomly divided into a control group and four treatment groups (home bleaching, home bleaching + fluoridation, in-office bleaching, and in-office bleaching + fluoridation). A spectroradiometer (SR) and digital images (DIs) were used to evaluate colorimetric parameters (Commission Internationale l'Eclairage L*a*b*) for all specimens. Color measurements were obtained before WSL formation (T1), after WSL formation (T2), and after completion of the external tooth bleaching treatment (T3).RESULTS:
The SR-based color change after bleaching was significantly greater in the treatment groups than in the control group (p 0.05).CONCLUSIONS:
The findings of this study suggested that external tooth bleaching with fluoridation can alleviate the conspicuity of WSLs.
