Evaluation of the effects of fluoride mouth rinse and varnish on the early biofilm formation of in two types of orthodontic adhesive resins: An study.

BACKGROUND

The aim of the present study is to compare the antibacterial effect of fluoride mouth rinse and fluoride varnish on the primary biofilm formation of () in two types of orthodontic adhesives.

MATERIALS AND METHODS

This is an study in which forty composite discs of Transbond XT and Lightbond were divided randomly into 4 groups: Group 1: Control group (not treated with fluoride), Group 2: Rinsed by 0.2% fluoride mouth rinse, Group 3: Rinsed by 0.05% fluoride mouth rinse, and Group 4: Treated by varnish fluoride. Then each group was placed in suspension. Bacterial suspension from each treatment was subcultured onto the surface of Mueller-Hinton agar plates, and bacterial growth was assessed. The results were analyzed by analysis of variance test and Scheffé test was run to compute the binary groups ( < 0.05).

RESULTS

There was a statistically significant reduction in the viability of in treated groups by fluoride but no significant difference between two types of composites.

CONCLUSION

The results of this study demonstrated that colonies were sensitive to fluoride and their most effective form was varnish. There was no significant difference in early biofilm formation of in two types of orthodontic adhesive resins Transbond XT and Lightbond.
