(PR159) Use of Cone Beam Computed Tomography in Pre-Doctoral Endodontics

Introduction: Cone Beam Computed Tomography (CBCT) has revolutionized dental imaging, providing detailed three-dimensional images of the maxillofacial region. Since its introduction in the late 1990s, CBCT has become an indispensable tool in endodontics, enabling precise diagnosis and treatment planning for a wide range of conditions, including periapical lesions, complex root canal anatomy, and traumatic dental injuries.

Aim: The purpose of this study is two-fold. One to analyze the use of CBCT in the pre-doctoral clinic at the NSU College of Dental Medicine with respect to enhancing diagnosis and treatment planning decisions for the pre-doctoral students and determining the need for a referral. Two, a survey distributed to predoctoral dental students in North American CODA-accredited dental schools to determine the current status of CBCT interpretation for endodontic diagnosis. Methods and Materials: A retrospective chart review of CBCT scans (2015-2023) was conducted to analyze indications for imaging. Additionally, a survey was distributed to third and fourth year predoctoral students to assess their knowledge and experience with CBCT interpretation in endodontics.

Results: Of the 207 CBCT scans analyzed, 90 (43.48%) were prescribed for anatomic anomalies followed by previous root canal treatment and calcified canals. Survey results regarding dental student knowledge and experience with CBCT interpretation are pending.

Conclusion: This study demonstrated a significant increase in CBCT utilization at NSU over the past several years. CBCT has become an indispensable diagnostic tool for endodontic treatment planning and case selection. To ensure optimal clinical practice, it is crucial to integrate comprehensive CBCT training into pre-doctoral dental education.
