The influence of technique modifications on sealant leakage.

Three medications in etchant and sealant application technique decreased dye penetration in vitro. The data appear to indicate that the clinical success of sealants may be positively influenced by such handling, suggesting a reevaluation of manufacturer's recommendations. Significant differences in dye penetration apparently exist between brands of Bis-GMA sealant, when applied without modifications in manufacturers' recommendations. However, there was a decrease in the difference between brands when the described variations in the technique of application were employed.
