Radiolucency Adjacent to Underfilled Root

Abstract

  In November, 1981, nonsurgical endodontic treatment was performed on the mandibular left first molar of a 37-year-old male at the author's clinic. Two of the three canals of this tooth were underfilled 2mm because of the presence of obstructions.

  Eight years later, radiographs revealed a radiolucency with a diameter of approximately 12mm associated with the apex of the mesial root canal of the tooth. Apicectomy was carried out on the mesial root, with a histopathological diagnosis of the presence of a cyst.

  This case suggests that long-term and short-interval observation be made on underfilled roots due to the presence of obstruction.
