Abstract
Objectives
This
in vitro study aimed to investigate the color changes of the
bracket-bonded tooth surfaces after the use of 4 different mouthwashes.
Materials and methods
A total of 100 human premolar teeth were randomly divided into 10 equal groups. Color values (L*a*b*)
of the buccal surfaces of each tooth were assessed using a digital
spectrophotometer. Then the brackets were bonded. The groups were put
either in sterile saline (4 test+1 control) or artificial saliva (4
test+1 control) solutions, and test groups were immersed in their
mouthwashes (Colgate Plax, Listerine Cool Mint, Klorhex, and Tantum
Verde) for 1 min each in the morning/evening to simulate the mouth
washing for 21 days after the bonding. After the debonding and finishing
procedures, final color measurements were performed. Color changes (∆E)
were calculated.
Results
All
of the parameters showed statistically significant differences among
the groups. The least noticeable color changes were detected in the
control groups. The most noticeable color change (ΔE) was observed in
the Tantum Verde + artificial saliva group, followed by Tantum Verde +
sterile saline and Klorhex + artificial saliva groups, all of which were
significantly higher than the control groups.
Conclusion
The
use of mouthwashes during orthodontic treatment may cause noticeable
changes in tooth color. Listerine Cool Mint may be the choice of
mouthwash with its less discoloring effects. Artificial saliva should be
preferred in similar in vitro studies to reflect the oral environment
better.
Clinical relevance
Mouthwash use during orthodontic treatment may result in different levels of enamel discoloration.
