Full mouth views and radiographs taken at the 22-month follow-up. Secondary caries developed on #7, with the loss of the resin composite restoration. Tooth #9 reveals no marginal deficiency but shows crown discoloration possibly due to an intrapulpal hemorrhage after the previous single-visit endodontic treatment. New caries developed on the interproximal surfaces of the posterior teeth. Compare with Figures 2A and 2B.
