[The effect of fluoride application following enamel etching on the adaptation and adhesiveness of adhesive fillings].
The application of fluoride to etched enamel and the subsequent influence upon the marginal adaptation and retention of adhesive restorations was examined in vitro. Results showed that amine fluoride (F- = 1.15%, I.E. 0.01%) and 8% SnF2 (F- = 1.94%) did not affect wetting of the conditioned enamel by sealer and composite material. However, a reduction in retentive potential evidenced by a partial loss of the restoration feather margin during circulation bathing was observed. Consequently, during adhesive restorative procedures, a fluoride treatment of etched enamel prior to sealer application and composite insertion is contraindicated. Upon completion of adhesive restorations a fluoride application, for example Elmex Fluid, to the entire operation field is, however, recommended.
