From: Richard Schwartz Sent: Tuesday, April 10, 2001 08 06 Subject:New case of the day Here is a fun case I did today. The patient presented with moderate spontaneous pain and tenderness to percussion. The tooth was hypersensitive to cold. As Jerry said, there is almost always a 4th canal in the maxillary first molars if you look hard enough. I had to go about 1/3 of the way into the MB root before the MB2 split off. You could see on the pre-op xray that it was going to be there. - Rick Schwartz

From: Fred Barnett Sent: Tuesday, April 10, 2001 16 18 Rick, As usual, great case! You are setting the bar quite high, which is fantastic. Are you using the Diadent .06 gutta-percha as your master cone prior to down-pack? Also, about how many times would you say that you needed to repeat the sequence of .06 series 29 files to finally get the #7 to WL? I find that on long, narrow roots, the crown-down sequence needs to be repeated a few times if I want the MAF to be a size 35 or larger. If you were to use the .04 taper series 29 files files, you will get to WL a little bit easier. Then you can use the .06 taper #7 as your last file after the .04 brown goes to length (to get the larger taper). I have played around with combining .04's and .06's in the more difficult to enlarge cases, and it "appeared" to be somewhat easier to get there. I am desperately waiting for the K-3 .06's from Analytic; I tested these in their prototype phase and they were sharper than the Profiles and appeared to get to the WL with less recapitulation and greater ease. - Fred
From: Richard Schwartz Sent: Wednesday, April 11, 2001 08 57 Thanks, Fred. I do use the Diadent .06 gp for the downpack. I usually have to go through the crown down series 2-3 times to get to the desired size. Sometimes more. I also do use the .04 tapered instruments on occasion. I ordered some of the Protaper instruments at the AAE, but they haven't arrived yet. We are looking forward to trying them. - Rick

From: John Coetsee Sent: Thursday, April 12, 2001 00 13 Dear Richard and all 1stly: You write that you could see that there was going to be a second MB canal on the question is --------- how 2ndly: a mention of using water with an ultra sonic instrumentation to remove bits and pieces out a canal. I missed the post and I would very much like to get hold of it ------- to read it. If any one has the posting, and could either forward it to the list or to me personally I would be most obliged 3rdly: to what size do you normally take the MB2 canal? (apical and at what flair?) Kind regards John Coetsee
