Periapical healing after simplified endodontic treatments: A digital subtraction radiography study

Aim To evaluate the 6-month outcome of endodontic treatment of periapical lesions with integrated systems by clinical examination and digital subtraction radiography (DSR). Methodology Eighty-four patients with chronic periapical pathosis were randomly allocated to two groups and received endodontic treatment with Revo-S/One Step Obturator (G1, n = 41) or GTX/GTX Obturator (G2, n = 43). Six months later, clinical examination and DSR analysis were performed. Non-parametric statistical methods were used (p < 0.05). Results Total healing, partial healing and failure occurred in 48.4%, 48.4% and 3.2% of cases in G1, in 50.0%, 43.8% and 6.2% of cases in G2, respectively. No significant difference was detected. Conclusions The integrated endodontic techniques allowed for a high 6-month success rate in both groups in accordance with literature data. © 2013 Società Italiana di Endodonzia.
