It's been a long road through this endo series but we are finally at the end- obturation! With so many techniques out there to seal root canals, which one is the best- or is there a "best"? We present details on what works and what the research says about the differences in obturation methods and sealers. We then discuss protocols for core build-ups, who should do them, and when they should be done. Finally, the controversy about posts is very real even to this day and we will weigh in on what we feel about the place of posts in dentistry.
