Abstract
Nearly two decades since Cone Beam-Computed Tomography (CBCT) was introduced in dentistry, this technology has been proven to be a useful asset in modern dental practice. The information gleaned from a CBCT scan influences treatment decisions and prognostication of challenging endodontic cases. The authors present six cases that utilized CBCT to diagnose vertical root fracture, to assess resorption, to guide the clinician in overcoming anatomical complexities, to hurdle diagnostic dilemmas and to perform pre-surgical evaluation. Initially, a thorough clinical assessment was performed; however, conventional periapical radiographs were not able to provide sufficient information to arrive at a definite diagnosis or a thorough treatment plan. CBCT was therefore deemed helpful for these cases. Clearly, there are advantages to using CBCT. With a better understanding of each case, the clinician can plan a definitive treatment plan and offer a clearer case prognosis to their patient.

There is overwhelming evidence that detection rate of apical periodontitis (AP) is higher when assessed with Cone Beam-Computed Tomography (CBCT) imaging than with PA radiography
Summary
Imaging is essential in various phases of clinical endodontics. For over 50 years, conventional two-dimensional radiographs have been used in endodontics to diagnose, treatment plan and assess outcome of a three-dimensional reality. Cone Beam-Computed Tomography (CBCT) produces three-dimensional images and multilayer scans of the maxillofacial structures that enable clinicians to visualize the dentition, the maxillofacial skeleton, and the relationship of anatomic structures in 3-D at a much lower radiation compared to a conventional computed tomography used in medicine [4] [5]. It utilizes an extra-oral scanner to create images using effective doses ranging from 5 to 652 μSv for adults and 7 to 521 μSv for children in a small field of view (FOV) scan [6] [7] [8]. In-vivo 5 imaging software (Anatomage, San Jose, CA) was used to analyze the scans
