Radiographic examination revealed the presence of a deep amalgam restoration and caries in the mesial aspect (Figure 3A). The root structure was not clearly demonstrated on radiograph (Figure 3A). Compared to typical buccal orifices diameters in maxillary first molars a large buccal orifice was found (Figure 3B). The working lengths were determined in the same manner as described for case 1 (Figure 3C); the canals were prepared and obturated as described for case 1. The patient was referred to the Department of Operative Dentistry for restorative treatment (Figure 3D). All three cases showed favorable results in one-year follow ups (Figures 1E, 2E, 3E).
