Abstract
Design
A randomised, parallel-group, controlled clinical trial.
Intervention
The test group had fluoride varnish applied onto the tooth surfaces with WSLs using a miniature cotton swab or brush and advised not to brush for four hours. The control group had saline solution applied.
Outcome measure
Status of the WSLs were assessed using a DIAGNOdent pen (KaVo, Biberach, Germany).
Results
Of the 110 participants recruited, 14 dropped out between the debonding and the six-month recall visit. There were statistically significant differences between the mean DIAGNOdent readings of the two groups at the three-month (P
Conclusions
A greater decrease in DIAGNOdent pen readings was found in the test group during the first six months after debonding. This may be taken to imply an improvement in the WSLs. Thus, topical fluoride varnish application appears to be a good method to treat WSLs and should be advocated as a routine measure after orthodontic treatment.
