Different angles of periapical radiographs for tooth #46 showed occlusal amalgam restoration, mesial and distal caries, periapical radiolucencies, and an additional root (Figure 1). The canals were obturated using warm vertical compaction (Figure 1) with Gutta-percha and AH Plus sealer (Maillefer Dentsply, Ballaigues, Switzerland).
