From: Marga Ree To: roots Sent: Thursday, June 07, 2012 1:18 AM Subject: [roots] orthograde retreatment of a root-end filling This patient presented with swelling and pain. 21 was surgerized a couple of years ago and the crowns on 21 and 22 were connected. I told the patient that I would retreat first, but that a resurgery could be necessary. Luckily we could remove the retrofilling with ultrasonics, Munce burs and some pre-bended explorers. She was asymptomatic after the first session, and we filled with MTA, a post and a composite core. Today she returned for a 1 year recall, and was happy to hear that surgery was not indicated - Marga orthograde retreatment of a root-end filling

orthograde retreatment of a root-end filling

orthograde retreatment of a root-end filling Great result , Marga. How do you think about the long term mechanical prognosis of those root end surgerized teeth? Is VRF an issue about which we should inform our patients? What numbers do you tell the patient. From the biological aspect I am pretty confident, that the long term success will be quite high in such cases. But what about the mechanics? Just out of curiosity: In the 1yearCBCT there is a radioopaque particle which I can not detect in the PA. What can this be? - Jörg Thanks Jörg Are you referring to the crown-root ratio? Lateral forces and parafunctional activity? Yes, that might be an issue, but I have to say that if there is sufficient radicular and coronal tooth structure, and an adequate ferrule, these cases have in general a favorable long-term prognosis. In my opinion, the role of the crown-root ratio is a bit overestimated. Remaining tooth structure is paramount, I'll post a case to illustrate this issue. The particle is probably extruded MTA, or CaOH that hasn't resolved - Marga Super, conservative result! Not much "luck" though, more like great skill and experience + application. So many of these teeth become implant cases these days. I like and place/restore implants, but NOT when the natural tooth is restoratively viable and endodontically treatable. Just one question, what is the small radiodense area on the recall CbCT, labial to the apex?. It looks like amalgam, possibly in the soft tissue, but is not on the recall xray. Thanks for posting - Ken Heritage Thanks Ken, I think it is either extruded MTA of CaOH that hasn't resolved. I have had some other cases in which CaOH failed to resolve - Marga Hello Marga. Its a great honor for me to talk with you. Great case and very nice healing. - Ricardo Machado Very nice case Marga. Thanks to this particle I realized that the MTA and the intracanal post look more radiopaque in the CBCT than it used in the periapicals. Of your answer I guess that that it is the same for CaOH. What is the explanation? Did you cut the retrofilling in some pieces with US @ Munce burs? If the retrofilling had extruded into the periapcial are, how would you resolved? Thanks for share and warm regards. - Nuria Campo, DDS I think Marc has answered your first question. As for removing the retrofilling, yes, I loosened it with US tips. I did extrude some of it in the peri-apical tissues, but was able to retrieve it again with pre-bended explorers. A matter of patience and persistence....:-)) - Marga
