Limited evidence indicates fluoride may prevent demineralized white lesions during orthodontic treatment
Linda L. Cheng, DDS, FAGD, ABGD
Systematic Review Conclusion
For the 3 studies identified on 3 modes of fluoride application for preventing white spots, only 1 was a well-conducted randomized clinical trial (RCT), which reported applications of fluoride varnish every 6 weeks during fixed orthodontic treatment may reduce the risk of developing demineralized white lesions (DWLs).
Critical Summary Assessment
A well-conducted systematic review of 3 RCTs, with 1 each at low, unclear, and high risk of bias, found moderate-quality evidence in 1 well-designed study indicating 1 specific mode of fluoride delivery—the use of fluoride varnish—may decrease the incidence of DWLs in orthodontic patients.
