“…The laser fluorescence test revealed that the Light Bond group exhibited the highest mean of fluorescence variation (ΔFV), indicating more enamel demineralisation around the bracket. The GC Fuji Ortho group exhibited the lowest mean of ΔFV, which can be attributed to the longer-lasting release of Fluoride by the Fuji Ortho LC (22) . On the other hand, we found that enamel demineralisation adjacent to ACTIVA in water media was more than the Fuji Ortho group, which may be due to less fluoride release from ACTIVA composite compared to Fuji Ortho (23) .…”

“…In addition, that study found that Fuji Ortho LC has detectable fluoride penetration, which is beneficial in reducing enamel demineralisation, whereas this property cannot be recognised for Light Bond (29) . This may be related to the effect of the primer layer in Light Bond, which prevents Fluoride from penetrating the enamel surface (22) . These results were consistent with the results of the present study.…”

background: This study aimed to evaluate the effect of bioactive composite (ACTIVA) on enamel demineralisation when used as an orthodontic adhesive, compared to other adhesives. Materials and methods: Human upper premolars (n=64) were randomly divided into two equal groups; the first group stored the bonded teeth in deionised water for 30 days at 37°C, and the second group exposed the bonded teeth to acidic media. Each group was further subdivided into four subgroups, with eight premolars in each subgroup, based on the type of adhesive used to bond metal brackets: non-fluoride-releasing adhesive (Transbond XT), fluoride-releasing adhesive (Light Bond), light-cured, resin-reinforced glass ionomer (GC Fuji ortho LC), and bioactive restorative composite (ACTIVA BioACTIVE-RESTORATIVE). Enamel demineralisation was assessed at baseline and after 30 days with a laser fluorescence device (DIAGNOdent™ Pen). Results: There were significant differences in fluorescence variation values (ΔFV) among all four tested adhesive systems in both water and acid groups after 30 days. Light Bond adhesive showed the highest fluorescence variation value, while glass ionomer showed the lowest, indicating less enamel demineralisation around the bracket. ACTIVA had less enamel demineralisation in acidic media. However, there was no significant difference in enamel demineralisation between water storage and acidic media groups. Conclusion: ACTIVA (RMGIC + composite) exhibited less enamel demineralisation than Light Bond; however, Fuji ortho LC showed the lowest enamel demineralisation.

“…Sustained release of a low level of fluoride leads to the formation of a calcium-fluoride layer at the enamel surface. This layer can provide fluoride for remineralization and calcium for neutralization of the acid attack [91,92]. All the methods used for fluoride application are effective to some degree.…”

Dental Caries - Diagnosis, Prevention and Management

Orthodontic treatment is the main treatment procedure to achieve a well-aligned dental arch and an esthetic smile. For this purpose, various types of removable or fixed orthodontic appliances are designed. However, each has their specific disadvantages. The most important one is that orthodontic appliances especially the brackets and the ligation mode create new retention areas in addition to blocking plaque-removing shear forces arising from fluid flow and masticatory loads with a resultant undesired effect of accumulation of dental plaque. Increased amount of dental plaque containing cariogenic bacteria is the main etiologic factor in decalcification of enamel during orthodontic treatment. This demineralization of the tooth surfaces results in appearance of white spots or even caries. However, in the literature, there are conflicting results in the relationship between orthodontic treatment and development of dental caries. Many preventive methods such as topical fluoride application, using bonding materials releasing fluoride, using mouth rinse with sodium fluoride, applying chlorhexidine, and so on were defined. The general comment of the authors is that supplying an adequate oral hygiene has the main role in prevention of demineralization-caries during orthodontic treatment. In the light of the previous studies' results, it can be concluded that professional application like a varnish can be provided for patients who have high caries incidence.

“…Considering the chemical approach, several in vitro studies analyzed the ability of many remineralizing agents to remineralize white spot lesions around orthodontic devices. For example, topical fluoride application [ 6 ], fluoride releasing adhesives [ 7 ] and casein phosphopeptides amorphous calcium phosphate (CPP-ACP) application [ 8 ].…”

Purpose This in vitro study aimed to compare the anticariogenic effect of using diode laser irradiation and/or nano silver fluoride varnish around orthodontic brackets. Materials and methods 60 caries-free and intact premolars were randomly divided into 3 experimental groups as follow: (1) Group I (nano silver fluoride treated group, n = 20), (2) Group II (diode laser treated group, n = 20) and (3) Group III (combined nano silver fluoride and diode laser treated group, n = 20). Anticariogenicity was assessed using polarized light, scanning electron microscope, elemental and shear bond strength analyses. Results PLM and SEM showed presence of few demineralized areas in group I. Group II revealed a dramatic increased demineralization. Group III disclosed almost typical homogenous surface enamel. elemental analysis showed a highly significant difference between Group III and II and a significant difference between Group III and I. Shear bond strength analysis revealed a significant difference between group I and II and between group III and II. The difference between group III and I was non-significant. Conclusion Both diode laser and nano silver fluoride positively affected dental enamel with the most superior enhancement in enamel criteria was achieved by surface pretreatment by combined nano silver fluoride varnish and diode laser irradiation.
