Detailed explanation-1: -The disadvantages include; the initial set up is costly and the sensor size is thicker than that of the intraoral films. For infection control, the sensor has to be covered adequately in a disposable plastic wrapper.
Detailed explanation-2: -The main disadvantages of direct digital radiography are the thickness and rigidity of the digital detector, infection control, hardware and software maintenance, and the higher initial cost of the system.
Detailed explanation-3: -The sensors can become damaged, necessitating costly replacement. > Digital dental radiography requires a computer in the dental operatory and extra time for computer patient input.
Detailed explanation-4: -Compared to conventional radiography and CR, DR systems are able to produce better quality images at lower X-ray exposures. With some DR systems, it is unnecessary to use a grid. Probably the biggest disadvantage of digital radiography is the cost of replacing existing radiographic equipment.
Detailed explanation-5: -Drawbacks or disadvantages of digital radiography ➨Digital radiography systems are very expensive. It requires computers, servers, storage devices etc. ➨It requires more storage space which depends on image sizes. ➨Digital images are prone to intentional manipulation for any misuse.
