Photography, the art and technique of fixing on a light-sensitive surface with the help of a convergent lens, an image produced in an obscure room, has become an essential element in the world of dental medicine. Its evolution and development represents a true privilege for physicians and as well as for the practitioners, detecting diseases and performing their activity.

For the quality of the photos, a number of rules will be required and some aspects will be taken into consideration: the patient should be placed on the chair with the head placed in the direction of the camera (the physician, along with the nurse, must be concerned that the patient stays in a stable, comfortable position), with the help of the retractors (the most commonly used being the transparent polycarbonate ones, due to the adjustability depending on the patient, found in different shapes and sizes) will remove the soft parts and set the frontal and lateral norms; using occlusal mirrors which will provide occlusal images of the maxillary teeth (the mirror being inserted into the mouth cavity in contact with the gingival mucosa, supported by occlusal surfaces of the maxillary incisors, distal to the last mandibular molar).
To prevent the steaming of the mirrors, they should be placed in warm water or use the air spray. Also, the background colour and choice of the camera improve the quality of the photos, indispensable for determining the patient's treatment. Lightning helps to avoid shadow areas, which are placed on both sides. For aesthetic rehabilitation, a single source is used previously leaving the shadow areas on the patient’s profile.

This is an essential and easier method of study for both the medical personnel and the patient.
