The images from a good intra-oral camera can be used for diagnosis but often are not enough for use in other functions – for cosmetic imaging cases, communication with laboratories or for documenting specific procedures. In cases like this, an extra-oral camera would be advisable. The first digital cameras were very expensive and is not able to meet the criteria used for producing diagnostic dental photographs.
More recently, better quality cameras, 5-14 megapixels, are available in the market. For getting a better picture of the tooth and zooming it on a computer screen, the 5 megapixel will allow you to resize the image to a size that can fill up an entire screen. These cameras usually have all the components – macro lens, flash diffuser, memory cards and battery charger.
