Maxillary first premolar retreatment

From: Chaniotis Antonis To: roots Sent: Thursday, March 29, 2012 1:35 PM Subject: Re: [roots] Retreatment or microsurgery SO BACK IN 2009 I WAS REFERRED THIS PATIENT FOR THE RETREATMENT OF HER MAXILLARY FIRST PREMOLAR. the tooth had been asymptomatic for over 15 years from the original treatment. Blocked canals but with no signs of pathology what so ever. I performed the re treatment. the canals were so difficult to negotiate to full length that i ended up using among other stuff the woodpecker technique as Rafael named it. I was really happy with the result. Almost three years later a lesion is growing at the apex. Somehow i suspected that i created an apical crack there. Things to take away: Mind your treatment rotary protocol and keep in mind that an apical crack is possible. apical cracks if removed surgically might save your case - Chaniotis Antonis Maxillary first premolar retreatment
