Intraoral radiography is integral to dental diagnosis while cone beam computed tomography (CBCT) provides enhanced 3D visualization. We aimed to assess and compare knowledge regarding CBCT and intraoral radiography among 386 Saudi dental undergraduates via a cross-sectional questionnaire. Nearly all participants successfully identified bitewing (99%), periapical (97%) and CBCT (98%) images, indicating strong familiarity. However, only 6% had clinically utilized CBCT versus 80% using intraoral radiography. Just 14% received CBCT training compared to 65% trained in intraoral radiography. Most appropriately recognized children as the most radiation-sensitive group (47%) and recommended limited CBCT (62%) and intraoral (37%) radiographs monthly per ALARA principles. Root canal treatment (44%) and implant planning (29%) were the most common CBCT referral indications. Key barriers to routine CBCT implementation included high costs (67%), difficulty (16%), and insufficient training (14%). Advantages perceived were reduced radiation (17%), rapid imaging (38%), and lack of film processing (24%). Results highlight excellent conceptual understanding but limited practical experience and training in CBCT compared to intraoral radiography among Saudi dental students. Targeted education programs integrating hands-on CBCT exposure with training in radiation safety and appropriate use are warranted to support optimal future clinical adoption.
