After access cavity preparation and straight line access.

Proceeded in the canals using D Finder file #10 and K Files #8 and #10 in simple watch winding motion with irrigation to see the maximum can reach !

However I couldn’t reach the apex cause I got stuck in the curvature and I decided to apply zone technique to enlarge above the curve using Gliders files size 10 taper 5% and 13 Taper 4%

Then enter again using TCA to reach FULLW.L

Achieving full WL using gliders on SGGP motion.

Fig. 3

And here as well I achieved FULL W.L in mesial root

Fig. 4

The master cones were reaching working length but however still they needed a push so I decided to apply Hot Modified Technique obturation so I can be able to push the GP apically further.

Fig. 5

Here afer the downpack you can see it reached full working length

Full obturation with final coronal restoration.

Conclusions

The right approach and a careful pre operative evaluation can help solving even complex cases
