Use SV to open crown until middle upper part. Widen the orifice of root canal by SV, Remove dentine, Brush Canal Wall by circumferential operating motion.

Glide path by using PX(#15/03) until working length.

Remove and Shape the canals with G1(#20/04) to the WL.

Fig. 5

Remove and Shape the canals with G2(#25/04)to the WL.
Required G2(#25/06) for larger canals.

Fig. 6

The pre-operative X-ray shows a large decay; we can also notice a deep split

THE MG3 BLUE sequence used for the case

Fig. 8

The X-ray shows the cone fit: the shaping obtained by using Perfect files respected the original anatomy of the canals

The video show us the   MG3  Blue    Heat-treated, increased cyclic fatigue resistance, enhanced flexibility

Fig. 9

Post operative X-ray

In these video I show you step by step the shaping with mg3 blue for a RTC of a 1.7


The rational for treatment is the most important part in our therapies, understanding the case difficulties a step back approach and correct instruments can lead us to endodontic success.
