Monitoring of cariogenic demineralization at the enamel–composite interface using swept-source optical coherence tomography

Highlights • Streptococcus mutans suspension was applied to form a cariogenic biofilm on composite restoration. • Swept-source optical coherence tomography (SS-OCT) was used to observe the carious demineralization at the cavosurface margins. • Demineralized enamel around the restorations was observe...

Description
Summary:Highlights • Streptococcus mutans suspension was applied to form a cariogenic biofilm on composite restoration. • Swept-source optical coherence tomography (SS-OCT) was used to observe the carious demineralization at the cavosurface margins. • Demineralized enamel around the restorations was observed as intensified brightness in SS-OCT image. • Cariogenic demineralization took place with the gap formation at the enamel–resin interface. • SS-OCT appears to be a promising modality for the detection of secondary caries at early stage.
