With the rapid developments in the field of computers and technology, newer methods of image acquisition and processing are available, which have been made very easy to perform. These systems utilize electronic media to record the image and advanced computer software to process the acquired image and also to modify it according to our needs. In digital imaging, the tonal value of each pixel is represented in a binary code. The binary digits for each pixel are called “bits,” which are read by the computer to determine the analog display of the image. The number of pixels-per-inch (ppi) is a good indicator of the resolution, which is the ability to distinguish the spatial detail of the digital image. The bit-depth and the pixel measurement of the pictures relate to the colours which are viewable in the image, and determine the size of the image file on a computer. Images with only two pixel shades – black and white – are binary. Grayxxscale images are typically displayed in an 8-bit mode, which is 256 shades of gray.
The aim of this article is to enlighten this latest imaging technology with its advantages and disadvantages and its multiple applications in dentistry
