A 65 years old patient came to my attention complaining about intense pain on the upper right hemiarch.

At the clinical examination, tooth 1.7 was hyper responsive to cold and presented an old amalgam restoration.

The periapical X-ray showed the presence of a secondary decay on tooth 1.7.

After the anesthesia, I isolated the tooth with rubber dam. Then I removed the existing restoration and the decay and started designing the access cavity

The color change on the pulp chamber floor clearly suggests the presence of four root canal openings.

Fig. 4

I shaped the MB1, DB and P canal with martensitic files at 500 RPM and 4.0 Torque, then I started shaping the MB2.
The inclination of the MB2 opening suggests the presence of a confluence between MB1 and MB2.

Fig. 5

The intra operative X-ray with gutta percha points in the MB1, DB and P and a k-file in the MB2 is useful to determine the fit of the master cones and to confirm the confluence of MB1 and MB2.

The root canals shaped, cleaned and ready to be filled.

X-ray to check the goodness root canal filling. If something had gone wrong, I would have fixed it immediately, before the setting of the sealer.

Conclusions

Being able to restore the tooth immediately, with a direct restoration or a build up followed by an indirect restoration, is a convenient and effective way to organize the clinical workflow for ETT.
