A further possibility, in order to make an accurate diagnosis, is the use of an intra-oral camera. This special colour camera is as big as a dental mirror. That is why it makes it easy to take images in the oral cavity. In addition the images can be enlarged on the computer which enables to detect defects on the tooth, you might have overlooked with the naked eye. Intra oral camera is also welcomed in the prophylaxis because you can show the patient what measure you have to take in order to achieve a final optimal oral hygiene.
