Effectiveness of a fluoride-releasing sealant in reducing decalcification during orthodontic treatment

White-spot lesions during multibracket appliance treatment: A challenge for clinical excellence

“…In the present study, standardized intraoral photographic color slides were directly used to perform the retrospective visual examinations. This method has also been reported in literature as a reliable procedure (Adriaens et al, 1990;Trimpeneers et al, 1996;Millett et al, 1999;Wenderoth et al, 1999). In order to maximally reduce the method error and increase the WSL identification, the slides were projected at 1.1m x 1.6m size at the evaluation time.…”

“…In the literature, several authors have used intraoral color slides to assess demineralization before, during, or after orthodontic treatment (Gorelick et al 1982;Sonis et al, 1989;Adriaens et al, 1990;Mitchell, 1992;Turner, 1993;Trimpeneers et al, 1996;Marcusson et al, 1997;Pancherz and Mühlich, 1997;Millett et al, 1999;Wenderoth et al, 1999;Mattick et al 2001). Willmot et al (2000) reported that WSL could be measured reliably from photographic slides converted into digital images.…”

“…Changes in the WSL prevalence and / or the WSL incidence during MB-treatment have been reported in literature (Gorelick et al, 1982;Mizrahi, 1982;Artun und Brobakken, 1986;Geiger et al, 1988;Øgaard, 1989;Mitchell, 1992;Wenderoth et al, 1999;Pancherz and Mühlich, 1997;Fornell et al, 2002;Zimmer et al, 2004;Lovrov et al, 2007) using a variety of WSL evaluation methods, inclusion criteria and prophylactic measures. Thus, extreme caution has to be exerted when comparing the results of different studies.…”

Does a chitosan-containing dentifrice prevent demineralization around orthodontic brackets?

“…2 These appliances are linked to a high risk of developing white-spot lesions. 3 The prevalence of new decalcifications among orthodontic patients with fixed appliances is reported to range from 13% to 75%. 3,4 Patients with orthodontic brackets have an elevated risk of caries, and enamel lesions can occur within a month, irrespective of mechanical plaque control and whether fluoridated dentifrice is used.…”

“…3,4 Patients with orthodontic brackets have an elevated risk of caries, and enamel lesions can occur within a month, irrespective of mechanical plaque control and whether fluoridated dentifrice is used. 3,5,6 Several methods have been used to prevent or reduce enamel demineralization during orthodontic treatment, including fluoride application in various forms, enamel sealants, rigorous oral-hygiene regimens using glass-ionomer cement for bonding bracket and modified appliance designs. [7][8][9] Chitosan and modified chitosans are interesting candidates in this respect.…”
