THE CONCEPT OF GUIDED TISSUE REGENERATION IN LARGE PERIRADICULAR BONY DEFECT: A CASE REPORT

Periradicular (PR) bony defects are common consequence of chronic endodontic lesions. Occasionally, conventional root canal treatment is not appropriate for complete regression of the lesion. PR surgeries may be warranted in such selected cases. PR surgery provides a ready access for the complete removal of pathologic lesion from the periapical region. Recently, the attempt of regeneration of the destroyed PR tissues has gained more attention rather than repair of it. In order to promote regeneration after apical surgery, the principle of guided tissue regeneration (GTR) has proved to be very useful. This case presents the management of a large PR lesion in a 20-year-old female. The PR lesion associated with lower anterior teeth was treated using PR surgery and GTR concept. The case was followed up for nine months radiographically and clinically. The principle of GTR improved the clinical outcome and prognosis of the endodontically involved teeth with a large PR defect by restoring the labial plate.
