Cone beam computed tomography is a new era in three dimensional world, modified from the computed tomography (CT) concept, involving the single rotation of an X-ray source around the dental subject. The data are analysed and reconstructed using a CT-based algorithm to create a volume of data, which can be viewed in three planes (axial, sagittal and coronal) and multiple alternative planes on manipulation of the data Acquisition of image is rapid and uses technology, which is becoming relatively affordable. A three-dimensional visualization of the region of interest is obtained in sufficient...

CBCT technology has grown rapidly to allow clinicians to acquire high resolution images of the teeth and craniofacial bones, using relatively low radiation doses. CBCT imaging has several applications in dento-maxillofacial diagnosis including endodontic diagnosis and treatment planning, implant treatment planning, surgical and orthodontic treatment planning, evaluation of the paranasal sinuses, temporomandibular joints, intraosseous pathology, impacted tooth, etc. Because of its higher specificity and sensitivity in relationship to hard tissue pathoses when compared to 2D imaging, this...

The endodontic management of a fractured instrument or any metallic object within the root canal is a sophisticated process that requires training, experience, and knowledge of the techniques that can be used. It is a time consuming and challenging procedure often associated with anxiety for both clinician and patient with variable success rate. Many factors must be considered before attempting to manage the instrument fragment.The prime therapeutic option for the management of instrument fracture is non-surgical aiming in the retrieval of the fragment. If this attempt fails, bypassing is the...
