Comparação entre o verniz fluoretado e o fosfopeptídeo de caseína - fosfato de cálcio amorfo fluoretado e não fluoretado na remineralização do esmalte ao redor de braquetes ortodônticos - estudo in vitro

Abstract

The orthodontic treatment with fixed appliances makes oral hygiene more difficult, favoring the accumulation of biofilm on the tooth surface and increasing the risk of dental caries in areas that normally have a low injury prevalence. The purpose of this study was to compare, in vitro, the capacity of the fluoridated varnish Duraphat (Colgate), the casein phosphopeptide - amorphous calcium phosphate fluoridated in mousse (Recaldent GC Plus) in remineralizing the tooth enamel around the orthodontic brackets. Therefore, orthodontic brackets (Morelli) were bonded with composite resin and adhesive system Transbond XP (Abzil - 3M) in 100 bovine incisors and divided randomly in four groups, the control group, and the three products tested. The four groups were exposed to the DES and RE cycling for a period of eight days. Enamel remineralization was evaluated using the laser DIAGNOdent ® (KaVo) (n = 100) and the scanning electron microscopy (n = 8). Statistical analysis was achieved using the Kruskal Wallis test followed by Student-Newman-Keuls test. The significance level adopted in the study was 5%. The results were significant not only in preventing demineralization, but also in the remineralization of the enamel surface around the orthodontic brackets considering the three groups tested when compared to control (p <0.001). The products tested demonstrated similar efficacy in remineralization of the tooth enamel.
