Preventive Effect of Ozone on the Development of White Spot Lesions during Multibracket Appliance Therapy

Abstract

Objective: To test the null hypotheses: (1) there is no difference in the caries protective effect of ozone and Cervitec/Fluor Protector during multibracket (MB) appliance therapy, and (2) DIAGNOdent and quantitative light-induced fluorescence (QLF) are not superior to a visual evaluation of initial caries lesions. Materials and Methods: Twenty right-handed patients with a very poor oral hygiene who required full MB appliance therapy were analyzed during 26 months. In a split-mouth-design, the four quadrants of each patient were either treated with ozone, a combination of Cervitec and Fluor Protector, or served as untreated controls. The visible plaque index (VPI) and white spot formation were analyzed clinically. DIAGNOdent and QLF were used for a quantitative assessment of white spot formation. Results:The average VPI in all four dental arch quadrants amounted to 55.6% and was independent of the preventive measure undertaken. In the quadrants treated with Cervitec/Fluor Protector, only 0.7% of the areas developed new, clinically visible white spots. This was significantly (P Ͻ .05) less than in the quadrants treated with ozone (3.2%). The lesions detected with QLF only partially corresponded to the clinically detected white spots, while DIAGNOdent proved to be unable to detect any changes at all. Conclusions: The caries protective effect of Cervitec/Fluor Protector during MB therapy was superior to ozone, and a visual evaluation of initial caries lesions was superior to both DIAGNOdent and QLF.

Effect of ozone on periodontopathogenic species—an in vitro study

“…In dentistry, ozone was discussed in endodontic treatment since 1951 [25]; nevertheless, clinical studies are missing. Ozone was found to prevent white spot lesions in orthodontic patients [26] and to stop or reverse fissure and root caries lesions [27,28]. Knowledge about a possible usage of ozone in periodontitis and periimplantitis is extremely limited.…”

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

“…Huizinga et al (1991) calculated that CHX would be need to be released from the varnish for at least 6 months after a topical application (Huizinga et al, 1991). Some studies have shown the efficacy of CHX varnishes in decreasing the prevalence of caries during orthodontic treatment, yet other studies have not shown the efficacy of a varnish of 40% CHX (Kronenberg et al, 2009;Øgaard et al, 2001). Moreover, the main benefits of CPP-ACP are their ability to localize at the tooth's surface and penetrate into the supragingival plaque to provide bioavailable calcium and phosphate ions where they are most needed (Reynolds et al, 2003).…”

Risk factors and management of white spot lesions in orthodontics

“…When combining chlohexidine varnish with a fluoride varnish (Fluor Protector), the cariostatic effect was enhanced even further in comparison to ozone, which also have been shown to decrease S. mutans count. [86]…”
