Good stuff Michael……I wouldnt cut dry to many times , and I have used the endo tips to work on calcified canals alot in the past.
In addition , with fiber posts and the scope your best bet is to just drill through them staying centered in the post.
There are new fiber post drill kits I have seen that basically heat up the fibers and removed them.
Keep an eye out for them. The scope and laser really are a great combination and keep sharing your experiences.
Good for you.
