Subject: [roots] Last 13 cases

These are the last 13 cases that i have treated at the program.

different shaping protocols for different cases. i used protapers, Gts K3s and Gates gliddens in different cases.
Interesting one is the mandibular second molar with the ML and Distal in a 'C' .i didnt realise that till the end

When I tried to fit all cones one time..distal blocked the ML to go to place.
the second to last maxillary molar had MB1 and Mb2 come together in the apical third and split again to have separate POEs.
I fit cones to where they joined and relied on WVC for the fill of the remaining 1 0r 2 mm of the canal space. the rest is routine endo.

In couple of cases I had overfills (i should have used LS for gauging in retrospect) in those cases.
Any critique is welcome. Too bad i didnt find any 5 canals - Sashi Nallapati












Very nice series Sashi--inspiring actually!  Thanks for posting them......  cjm

You used different methods to clean and shape , what about different obturation techniques, materials?
what is your opinion on cold lateral condensation??
Does it effect endodontic success? any evidence?  - venkat

If you look at A retrospective comparison of outcome of root canal treatment using two different protocols.

They found no difference in the success based on obturation technique (cold vs warm). On the other hand Friedman's Toronto Initial treatment
outcome study part 1 showed a higher success with warm than cold but not statistically significant.J Endod. 2003 Dec;29(12):787-93.

In my opinion the obturation technique (well fitting single cone , warm ,cold lateral ) doesnt really matter as long as the canals are cleaned
and shaped well and some sort of definitive restoration placed to prevent coronal leakage - Sashi Nallapati
 
And..........do not forget the importance of microorganisms - Fred...greetings from Toronto

Sashi...this is another one of those items you see a difference with time.....5 years is to short....it's 7-10 years out before you see a difference.  Unquestionably, Shaping and Cleaning are important...Coronal Leakage is important....
but who knows exactly how these are ordered and where the difference is between lateral and vertical come in......Joey D
