A Busted Lentulo Spiral.
Iatrogenic April 16th, 2007
Someone tried to do a root canal on this tooth many years ago. I guess they decided to stop after they broke a lentulo in the MB canal.
If you’re gonna break an instrument, break one of these because they come out fairly predictably. I used a technique that OfficeMom and I developed a few years ago to retrieve canal objects. It involves bypassing the object with a couple of files, winding them together and pulling. It’s essentially the same thing that the paediatric dentists do to get pulps out.

i love how they put a post and crown on the tooth after that. it’s like, hey, instument’s broken, guess my work’s done now.
i’ve never use a lenticulospiral to instrument before, we were never taught that, but i have seen several busted ones, esp since i moved here. it’s funny, too, because every time you see one, the root canal is *never* completed, just a single broken instrument and totally empty canals.
i don’t have lenti’s in my office and i’ve never used one. one endo resident when i was an undergrad helped me used a series of gates gliddens to open up the canals before instrumentation, but i thought lentis were for cement application and such.

I used to use lentuolos for Calcium Hydroxide placement, and sometimes sealer placement, but now I use my profile rotaries in reverse.
I use GGs all the time. They are a cost-effective, efficient way to create straight-line access in the coronal 1/3.
