The anti-erosion effect of fluoride on the enamel surface was investigated by ATR-FTIR, SEM and EDX techniques. Four extracted teeth (two incisors and two premolars) were initially bleached with carabamide peroxide and etched with ortho-phosphoric acid then fluoride treatment was applied. Significant differences in enamel composition and morphology were observed providing the effect of fluoride application in remineralization of teeth. Infrared spectroscopy was employed to probe the changes in enamel structure. Scanning electron microscopy/energy dispersive X-ray spectroscopy analysis revealed higher content in F of teeth enamel. Morphology changes revealed a re-mineralization of enamel surface after the treatment with fluoride gel.
The aim of the present study was to assess the remineralizing potential of 10% casein phosphopeptide-amorphous calcium phosphate complex (CPP-ACP) -Recaldent used alone or with fluoride (CPP-ACFP) as compared to fluoride mouthrinse for the non-invasive treatment of occlusal non-cavitary caries lesions in vivo.A total of eighty subjects were randomly assigned to four groups, i.e. group 1 - 10% CPP-ACP, group 2- 10% CPP-ACP + 0.2% NaF, group 3- 0.05% NaF mouthrinse and group 4 �control. The lesions were assessed using visual examination and DIAGNOdent measurements. After 12 weeks of using the corresponding product, the results showed that the highest decrease in fluorescence was produced by CPP-ACFP (from 16.28�1.40 to 6.53�0.59, p=0.002), followed by CPP-ACP (from 15.70�1.82 to 8.18�0.70, p=0.004) and fluoride mouthrinse (from 14.32�1.72 to 7.88�0.68, p=0.005), significantly higher than in the control group (p[0.05). No significant differences were found between the three treatment groups.
The aim of the present study was to assess the correlation between salivary (flow rate, pH) and clinical (GI, PI) parameters and the use of two common mouthrinses in young adults. A total of ninety subjects were randomly assigned to three groups, i.e. group A -Listerine�, group B -0.05% sodium fluoride, and group C -distilled water. After 6 weeks of using the corresponding mouthrinses twice a day, the results showed that Listerine� produced the highest increase of the salivary pH (7.58�0.043) and flow rate (0.82�0.280) and the highest decrease of the GI (0.79�0.177) and PI (1.30�0.375). Significant correlations (p[0.05) were found between the use of mouthrinses and the salivary and clinical parameters examined.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
