I read somewhere that somebody suggests using lateral condensation over vertical for the board exam. I can't figure out why. Can somebody shed light on the difference between those two techniques? Studies show that vertical is more superior but in real world I think more dentists lean toward lateral though. Thanks in advance.

Knowing what I know now, I would probably use Resilon single cone technique on the board exam. You should use rotary, so use .04 taper endosequence from Brassler and obturate with a #30 or 35 resilon cone. No voids, perfect fill...ez pass on boards
thanks for your replies. Can anyone elaborate on Resilon cone technique? What material would we need? for the boards, is it necessary to do backfill. I heard people just fit the Master apical cone with copious sealer so that there is no voids that can be seen on the Xray. Our school would supply us with Obtura and system B. The goal of this game is very simple: Just fill the canal with gutta purcha and make sure voids can be seen radiographically. What would be the best way to go around this test?
👍👍👍
I used pre-tapered gutta percha, single cone technique. As mentioned above, use rotary. Whatever the taper of your file sequence is, use the same taper single cone gutta percha. It works great-- and if the canal looks a bit unfilled, you can use a few F or MF gutta percha cones for lateral condensation.
I was browsing online for pre taper gutta percha. Some advertise their products compatible with protaper rotary system which is what we have been using in school. What does 0.04 or 0.06 mean? which one should I get? #15, 20, 30 correspond to the Master apical file size at the apex, right?

How do you not know what .04 and .06 are if youre going to take your test soon?

Let me go over a few things for dentaql students that schools don't teach very well.
Hand files are typically .02 taper...if you want more taper, rotary files are the way to go...
Now I am familiar with two types of rotary techniques:
Protaper and Endosequence...
having used both, the latter in my opinion is the better option. Protaper is a lot more aggressive meaning that the chance of breakage of the file is higher.
taper means how the file expands from the rotary file tip to the end that enters the handpiece. .04 taper is less flared than .06...
the reason i mainly use .04 taper in practice is because most posterior teeth have canals that are relatively small and dont really need to be expanded that much to debride the canals completely. For upper anterior teeth I do use .06 taper because the canals are initially larger and needs a more flared file to shape the canal properly.
For the boards, try this.
1) Access opening...
2) file to size 20 (with hand file .02 taper)
3) get working length
4) rotary file .04 taper to size 30 (15, 20, 25, 30) to working length..
**do not force the rotary file down...slowly continuously go more apically until WL is reached**
5) Place Resilon cone inside canal and take x-ray making sure obturation goes to length
6) remove resilon and reinsert using sealer
7) final x-ray

Thanks all for input. I was under the impression that protaper has varying taper, not like uniform 0.02" taper for hand files. We got only one size of protaper rotary files and I don't know which taper size of cone(..04 or .06) I shoud get with the system.
