Endodontic Predictability: “Are You Making the Right Decisions?”

Decision No. 8: Should I Make a Conefit Prior to Obturation (Figure 4a)? Q: “Is it necessary to validate your radicular shape before you pack?” 
A: Is it necessary to make an accurate impression before you cast an onlay? Of course it is. In endodontics there is an old saying that goes like this: “You don’t get what you want; you get what you measure.” Regardless of your obturation technique: vertical compaction of warm gutta-percha, continuous wave, carrier-based, or lateral condensation, you need to know if you are ready. The conefit tells you that you are ready. In warm gutta-percha techniques, the conefit additionally allows you to modify the cone itself before compaction which gives you additional refinement in endodontic finishing.10
Guideline No. 8: Develop the skill of making an accurate conefit prior to obturation.

Decision No. 9: What Obturation Method Is For Me (Figures 4c to 4e)?
Q: How do you create the maximum cushion of warmed gutta-percha and mold it 3-dimensionally?
A: The easiest obturation method to learn is lateral condensation. The next is carrier-based. The next is continuous wave. And the next is vertical compaction of warm gutta-percha. 
The easiest to control is, in the opinion of the author, in this order: vertical compaction of warm gutta-percha, lateral condensation, continuous wave, then carrier-based.
The method that gives you the most choices are in this order: vertical compaction of warm gutta-percha, continuous wave, lateral condensation, then carrier-based.
The best 3-D endodontic seal is achieved in the following order: possibly carrier-based first, then vertical compaction of warm gutta-percha, continuous wave closely behind, and then lateral condensation.
The most technique sensitive order is: vertical compaction of warm gutta-percha, carrier-based, lateral condensation, and then continuous wave. Guideline No. 9: Choose an obturation technique where you don’t have to think too much. Obturation is a time to relax. It should not be a sporting event!
