Control of White Spot Lesions with Use of Fluoride Varnish or Chlorhexidine Gel During Orthodontic Treatment A Randomized Clinical Trial

Abstract

After 3 months of treatment, F, CHX and CO were capable of controlling the WSLs adjacent to the orthodontic brackets. However, the treatment with F was capable of controlling the progression of the WSLs in a shorter period of time.

Efficacy of fluoride varnish for prevention of white spot lesions during orthodontic treatment with fixed appliances: A systematic review study

“…Fluorescence value at the end of the intervention (3 months) vs. baseline was (7.2±1.6 vs. 17.2±2.3), (9.2±1.6 vs. 16.8±1.8), and (10.5±2 vs. 17±1.7) for fluoride varnish, CHX gel, and control, respectively (P<0.05). These values were less than fluoride varnish compared to CHX gel after 3 months, and compared to baseline (Restrepo et al, 2016).…”

“…The number of WSLs at the end of the intervention (3 months) versus baseline was less for fluoride varnish compared to control, or for control compared to CHX gel (Restrepo et al, 2016).…”

Comparative Evaluation of Fluoride Varnish Single and Re Application on Demineralization Adjacent to Bonded Brackets

“…The positive effect of fluoride varnish reapplication was also supported by other study (Virupaxi S et al, 2016) in which they found that the reapplication of fluoride varnish decreased the demineralization and prevent or control white spot lesion progression. Moreover, Restrepo M et al, 2016 found the same positive effect of fluoride varnish reapplication till the fourth application only, further applications didn't show any positive effect (Restrepo M et al, 2016). This is due to the fact that fluoride varnish flows and adheres to the teeth surface and as it comes in contact with saliva, it slowly wears away over time, and the sodium fluoride and calcium phosphate in the varnish dissolve and are released as ions.…”

“…Topical fluoride agents had a great value in decreasing enamel demineralization both invitro and in-vivo studies (Mdos N et al, 2016 andDa Camara D et al, 2016). However, limited studies tested the efficiency of fluoride varnish reapplication in preventing white spot lesion formation in orthodontic patients (Baygin O et al, 2013, Nalbantgil D et al, 2013, and Restrepo M et al, 2016. Thus this study was conducted to investigate if reapplication of fluoride varnish would have superior benefit on single application in preventing enamel demineralization around orthodontic brackets.…”

Effect of enamel pretreatment on the fluoride remineralization of artificial white spot lesions

“…T he remineralization of non-cavitated incipient lesions associated with the control of etiologic factors is the early way to reestablish the integrity of the tooth structure caused by caries disease and reverse this scenario [1][2][3]. For this purpose, fluoride-base compounds are the most investigated and used agents themselves or associated [4,5].…”
