Subject: [roots] Fwd: High pulp horn

When this tooth was referred to me for RCT in 4, i was positive that the 
tooth was cracked. and that's why it got infected. she had a done a 
filling in 4  a few years ago. as you can see from the BW, the 
restoration is quite far from the pulp. when i removed the amalgam, 
I didnt see any cracks which got me wondering why did the pulp become 
necrotic. as you can see, right below the amalgam there was a pin point 
pulp expsoure. the expsosure came about due to a very high pulp horn 
just about 3 mm below the occlusal surface. these sort of exposures go 
unnoticed to the naked eye since one doesnt expect the pulp horn to be 
that high up. any way RCT was completed in one visit.
i was expecting a lot of lateral canals seeing the spread of the lesion 
around the tooth. You can see a good bit of lateral anatomy got filled.
I did recommend cuspal protection for this tooth. all in all interesting 
to see the high pulp horn in this case. that's why BW are important to
assess the proximity of the pulp horn to the occlusal surface.

beautiful obturation Sashi! Its very humbling to see the great work 
posted here on roots.

Could it have been a possible dens evaginatus? The lower second premolar 
also seems to have the pulp horn extending high up coronally on the 
bitewing.-  Imran

Absolutely could be a DE. particularly looking at 29. thanks Imran - Sashi

Beautiful work. Do you expect lasering the pin point exposure followed by 
GIC could have helped keeping the pulp alive longer - Henry

if it was an iatrogenic exposure, at the time of the filling, placing MTA 
and then GIC over it, may have worked. If it was carious, then very little 
chance of pulp cap working. pulp capping in general  is an unpredictable
procedure in adults - Sashi

great job ,  by the way , it is 5 not 4 . - Magdel

thanks american system, its 4 - Sashi

Sashi, Sorry for the late reply on this thread.  Just got back from hol 
in Mallorca.  I wanted to say that I really enjoyed your talk on 
complicated premolars in Barcelona.  V inspiring :)

In this case, I'm guessing that it didn't take you too long to shape the 
canal.  I'd like to know, typically how long you have irrigant (hypochlorite) 
flowing through the canal before obturation.

I'd also like to ask you and the other Rooters too which brand of K-Flex 
files you use to create the glidepath. I have been taught that K-Flexofiles
are good in severely curved canals.- Nik

NIkhil  you are right,  shaping took me little time.
after the shaping and gauging  is complete, i irrigated with hypo at least
10mls  and then used a fine ultrasonic tip to agitate the hypo while 
irrigating the canal about 5 mnts. then EDTA and ultrasonics
about 2-3 mts and  final rinse with hypo. then dry and obturate.
I like flexo files as well. - Sashi
