Based on the radiographic characteristics, lesions were categorised as I\u2010shaped (unilateral intrabony defect without apparent apical radiolucency), J\u2010shaped (unilateral intrabony defect with apical radiolucency) and U\u2010shaped (bilateral intrabony defects with apical radiolucency).

The estimated 1\u2010 and 5\u2010year tooth survival rates were 83.8% and 58.9%, respectively. Multivariate analysis identified age, EPL grade, probing depth (PD), periapical index, bone loss and I\u2010J\u2010U subclassification as significant prognostic factors for tooth survival. The I\u2010J\u2010U subclassification was significantly associated with tooth survival, suggesting its potential value in prognostic assessment.<\/jats:p>\n                  <\/jats:sec>\n
