I was told by my oral surgeon, after having a CT scan, that I have a periapical lesion between the roots of a tooth I have had a root canal on. Is a lesion the same as an abscess? I was told that the lesion is between the roots, but if I had a root canal, aren't the roots gone? I wonder if the lesion is in the canals.

  • In root canal treatment the canals present in the roos are treated . it is not that the roots are gone. Roots are very much there . The oeriapical lesion can become tose abscess if not treated. it is the infection present at the apex of the root that is why it is called periapical lesion. if it is between the roots that means the furcation area is involved . Furcation area is the area where the single root that is the trunk bifurcates into the roots.if the lesion is in between the roots that tooth has poor prognosis.
