Rajeswari Kalaiselvam, Eswar Kandaswamy, Deivanayagam Kandaswamy

Diagnostic imaging is an integral and essential component of Endodontics, especially for periapical lesions. Recent research has seen an increase in the development and testing of new and improved techniques. Ultrasonography (US) has the advantage of being a non-invasive, painless, rapid and radiation free method. It is also capable of revealing considerable amount of details on soft tissues and differentiates various periapical pathologies like cysts, granulomas, abscesses and surgical scars with their size and dimensions in the anteroposterior, superoinferior, and mesiodistal planes. Evaluation of imaging techniques is important to ensure optimal monitoring of the outcomes of surgical and conventional endodontic treatment and to diagnose periapical lesions accurately. The present literature review focuses on the principles and rationale behind the usage of US in the field of Endodontics.
