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 imaging technique may be used for multiple clinical applications and research. CBCT has brought clinical benefits to almost all areas of dentistry.Therefore, in contemporary Endodontics, technological innovations supported by three-dimensional CBCT studies have established a true revolution, which has naturally led to the need to review some structured concepts based on conventional imaging methods
