Endodontic procedures 1

There is some steps to do in a endodoncy. 

1. Open the chamber with the abrasion drills and with endo-Z drill we. Find the direct access to the apical foramen with the drills. 
2. Expansion of the cavity to adjust for the posterior obturation. 
3. With SX we have to wear the dentine triangle, then it will be easier for the apical curvature. This step is optional.
4. Use the apical localization to find it.
5. Then we start with the limes of conformation:
1. S1 + irrigation + passenger lime
2. S2 + irrigation + passenger lime 
6. In the next picture we see the passenger lime that we have to pass in almost every step.
7. After this lines we pass the limes of finishing:
1. F1 + irrigation + passenger lime
2. F2 + irrigation + passenger lime
3. F3 + irrigation + passenger lime

Each lime has a different apical diameter that makes the apice bigger. Then we also have the Profile System.
The next picture is the apice localizator, there is a lot of kind of localizator. What we have to know is that they indicate you the length of the conduct.
