Final answer:
Faster image acquisition is the most attractive advantage of digital imaging for a busy dental practice, due to the efficiency and increased patient throughput it offers.
Step-by-step explanation:
Among the advantages of digital imaging for a busy dental practice, faster image acquisition stands out as the most attractive. With the refinement of x-ray technology and the introduction of faster films, the exposure time for both patients and dental staff has been reduced, thereby increasing the throughput of patients and improving the efficiency of the dental practice. This advantage supports a busy dental office's need to manage time effectively, allowing for more patients to be seen with reduced wait times for diagnostic imaging. It's worth noting that while all these advantages like higher image resolution, reduced radiation dose, lower equipment cost, and faster image acquisition are important, the speed of acquiring images can have a significant positive impact on the workflow of a dental practice.
