In recent years, digital imaging has become an important tool in dental practice. While digital radiology sensors have existed for many years, it was the introduction of intraoral cameras that spurred many dentists to adopt new imaging technologies. Early intraoral cameras were analog and had to be connected to a TV monitor. Today, they are being replaced by digital cameras that integrate much better with other imaging devices. In tandem with the development of digital radiography and intraoral cameras, the emergence of digital photocameras has led to a more comprehensive view of imaging in the dental practice. Regardless of their source, all types of digital images can be stored, manipulated, analyzed, and retrieved on a computer. Successfully implementation and use of digital imaging requires a thorough understanding of such systems and their component technologies.

Basics of Digital Images presents the concepts and technologies that digital imaging systems are based on. The chapter begins with brief review of the physiology of human vision, and then covers resolution, color depth and file formats of digital images in detail.

We discuss Image Management in dental practice next. A comprehensive approach to image management is essential to fully realize the benefits of digital imaging. Optimal image management systems support a smooth, seamless and efficient workflow for digital imaging.

Image capture, storage and output discusses concepts applicable to most or all types of digital imaging devices. Imaging devices typically use specialized sensors for image acquisition. Some store images before they are transferred to a computer, while others transmit images directly to a computer. A variety of options is available for displaying or printing digital images.

In the chapter Intraoral Cameras, we discuss one of the most frequently used imaging device in dental practice. Intraoral cameras can support patient education, diagnosis and treatment. We describe the types of cameras, their physical location and integration, operational aspects, and image quality and properties. On the book Website, we provide a review of several currently available products.

Digital cameras provides an introduction to a device that is rapidly becoming very common in dental practice. We discuss camera types, the camera body and its components, camera controls, image capture and image storage. Ease-of-use is an important evaluation aspect, especially since many digital cameras provide more functions than their traditional counterparts. . The book Website provides a review of several currently available products.

The chapter Digital Radiology discusses digital radiology applications in dental practice. It covers direct digital radiology, computed digital radiology and indirect radiology.

In the chapter Switching from Traditional to Digital Imaging, we discuss strategies to ensure a smooth transition to a digital imaging system. Benefits of digital imaging systems include immediacy, quality control, flexibility, and availability. However, these benefits can only attained through thorough needs assessment and planning. It is especially important that a digital imaging system complies with current and emerging standards. The chapter also presents a strategy for implementation, and upgrading and maintenance.
