Effect of Caries Infiltrant on Margin Integrity of Composite Fillings Placed Adjacent to Demineralised Primary Enamel


Attin, Rengin; Rüedi, Nathalie; Tauböck, Tobias T; Körner, Philipp; Wiedemeier, Daniel; Attin, Thomas (2021). Effect of Caries Infiltrant on Margin Integrity of Composite Fillings Placed Adjacent to Demineralised Primary Enamel. Oral Health & Preventive Dentistry, 19(1):603-608.

Abstract

PURPOSE
To investigate the influence of pretreating demineralised enamel with an infiltrant on the margin integrity of Class V like composite restorations on primary teeth bonded with different adhesives.
MATERIALS AND METHODS
Forty specimens from primary molars were demineralised and circular class-V-like cavities were prepared. The cavities were treated with a universal adhesive (Scotchbond Universal Adhesive, 3M Oral Care), applied either in self-etch (SE) or etch-and-rinse mode (ER) mode. In groups SE-I and ER-I, the demineralised margins were pretreated with a caries infiltrant (Icon, DMG) prior to adhesive application. The cavities were restored with a nanofilled composite material and thermocycled. Marginal integrity was evaluated using SEM, and the percentage of continuous margin was statistically analysed.
RESULTS
Specimens treated with the caries infiltrant followed by the adhesive showed similar marginal continuity as the adhesive alone.
CONCLUSIONS
Pretreatment of demineralised primary enamel with a caries infiltrant before applying a universal adhesive does not influence the marginal integrity of composite fillings.
