A story of a dilacerated premolar

Fig. 1

Radiographic evaluation revealed deep distal decay and dental tissue loss. Also, we can observe that we have two canals. The canal anatomy seems intricate with abrupt dilaceration

After proper anesthesia and isolation, we removed decay. Then.

we did some preflaring in order to make sure that all files reach the point of the first curvature unobstructed. Next, with a hand file we determined the exact point of the second curvature but did not try to negotiate it at this point. Finally, we prepared with mechanical files up to his point. This is the zone technique. Of course, irrigation is mandatory between each file to avoid blocking the canal. The secret to this point is to completely forget the apical curvature and focus first to instrumenting up to that point.

Now is the time to precurve hand files ( c-pilot VDW ) No 8 & 10. 

Crown – Down technique with balanced force allowed us to reach up to this point. After the second curvature I used only hand files because it was abrupt in a buccal distal direction and we had more control. However, as we can observe there is apical pathology so we dedicated a lot of time to irrigation and activation with internal heating method.

This is the obturation radiograph of teeth # 14, 15

We can observe the abrupt curvature in the second premolar but also the apical ramifications and lateral canals.

Now the most important : Follow-up

The patient did a CBCT to evaluate bone for an implant 

So we can observe that 1,5 year later the area seems to have a good healing.
