too small access cavity opening

[etrexx]

@cyam6452

what do you thing is a bigger cavity opening good for in this case?

- straighter access? IMHO No

- more canals? IMHO No

- less pulp tissue? IMHO No

- better disinfection? IMHO No

I think you must read the articles about the SAF at first.

1 - The self-adjusting file (SAF). Part 1 respecting the root canal anatomy--a new concept of endodontic files and its implementation.

2 - The Self-adjusting File (SAF). Part 2 Mechanical Analysis

3 - The self-adjusting file (SAF). Part 3 removal of debris and smear layer—A Scanning Electron Microscope Study.

I can send the articles to you, if you haven't got.

Good Job doc..but c...you are using the SAF on a rotary system...while SAF is not rotary..u did mention that it vibrates up in down 0.4 mm amp..but u still mount it on rotary!

btw..is that 0.5 mm of percha out of the canal accepted for u?

@TheStafne

The SAF ist used in a special handpiece (Vatea) from the manufacturer of the system in this video. Only when the file binds there is a vertical movement (which is hardly seen in the video). When the SAF is free in the canal it rotates, which makes absolutely sense because otherwise the canal will not be prepared smooth. If you use the SAF in a norm. handpiece you will destroy it within seconds.

The seal extrusion is due to Schilder-Technique and not SAF specific. For me it is OK.

@etrexx tx,

so the SAF,after finishing up-down movement, will go rotating on the same handpiece? does it have a system to adjust the nature of movement?

if that extrusion is seal,not gutta, it is ok for me 2 ;)

[kareemken]

you do the best endo videos... for real :)

so interesting to see someone catching up with the SAF already.

i learn alot from your videos.

i'd like to know your opinions of K3.. and is the move to TF important?

i'm trying to stop relying on PT because it seems to have a high incidence of seperation. so now i use PathFiles/Revo-S/K3 or a subset of these.

also would love to see a video of different techniques for retrieving seperated instruments.

greets from kairo

@kareemken

Thank you! I hope to come to cairo in the near future!

The TF is a huge improvement over the K3. Much more flexible and more resistant agains cyclic fatigue.

The PT is a great system. I love the S1 for preflaring procedures.

Prevention of overinstrumentation is as with any other endodontic instrument, but you must know that the handpiece vibrates the instrument vertically with an amplitude of 0,4mm

I think the composite is a buccal filling, after the treatment I placed a fiberpost into the canal.

Straight-line access is key using the SAF (as with any other endodontic instrumentation), otherwise you will damage the instrument very rapidly.

Few questions...

How do you prevent over instrumentation?

Why is there composite in the pulp chamber?

Doesnt it interfere with straight line acces?

Thanks in advance...
