The Accuracy of a New Cone-beam Computed Tomographic Software in the Preoperative Working Length Determination Ex Vivo.

Introduction: This study investigates the accuracy of 3D Endo software (Dentsply Sirona, Salzburg, Austria) to determine the working length when using preoperative cone-beam computed tomographic (CBCT) scans of extracted teeth, compared with conventional CBCT software and an electronic apex locator (EAL).

Methods: CBCT scans of 30 premolars were obtained. Using OnDemand3D software (Cybermed, Seoul, Korea), the measurement obtained from the coronal reference to the apical foramen (AF) was recorded as the conventional CBCT length.

Spontaneous Resolution of a Central Giant Cell Granuloma in a Child After an Incisional Biopsy: A Five-year Follow-up.

A central giant cell granuloma (CGCG) is typically regarded as a benign lesion with osteoclastic activity. Treatment often involves surgical procedures that may cause deformities; however, minimally invasive approaches have been suggested for treating pediatric patients. We report a case of CGCG of the mandible in a 13-year-old boy who presented with a well-defined radiolucent area in the anterior mandible that was initially detected in a radiographic examination for orthodontic purposes.
