Case Description: An 18-year-old male presented with sensitivity to thermal changes in a lower molar. On clinical and radiographic examination, areas of micro-filtration were observed on the resin restoration. 

After the restoration and recurrent caries were removed, the cavity was decontaminated with 2% chlorhexidine, leaving a visibly wet dentin. I then placed TheraCal LC, selective etched with 35% phosphoric acid on the enamel, dried, and applied All-Bond Universal. Fluid resin was used to seal the exposed dentin and create the resin coating. 
An impression was taken with a triple tray to create an indirect resin restoration. I then cemented the indirect restoration, decontaminated the preparation with 50-micron aluminum oxide, etched the enamel with 35% Select HV phosphoric acid, dried, and applied All-Bond Universal. To finish, I light-cured and completed cementation with Duo-Link Universal adhesive cement.
