Background: This study used cone-beam computed tomography (CBCT) to compare a stainless-steel Tornado file system with OneShape and WaveOne rotary systems for biomechanical canal preparation as indicated by the healing of periapical lesions. Methods: Lower molars with necrotic pulps and periapical lesions were arbitrarily divided into three groups (n=20) rendering to three rotary file systems. After root canal treatment, clinical and radiographic assessment of the apical radiolucency was evaluated at one year using pre- and post-instrumentation CBCT images. Statistical analysis was performed to compare the three systems at a p-value of 0.05.
