Briefly describe the purpose of oral macro photography.

Its main purpose is to observe the detailed structure of oral cavity more clearly and accurately, and to provide more accurate basis for the diagnosis and treatment of oral diseases.

The necessity of oral macro photography;

It can objectively and concretely show the symptoms and changes that can't be seen by naked eyes, and the oral photos taken by the system can be shown to patients, which can deepen patients' trust in clinic.

The benefits of oral photography are as follows:

1, for patients

No one can directly see his face or inside his mouth. In order to let patients choose the correct treatment plan, provide information.

2. For medical treatment.

A good photo is inseparable from everyone's efforts. Dental care begins with learning oral photography. Any medical staff can't grow up without taking pictures. They can not only learn the observation methods in the mouth, but also learn the treatment methods. It is easier to get a diagnosis, which is helpful to track the treatment process of patients and confirm the curative effect. You can explain it while looking at the photos.

The importance of oral photography;

1, oral photography is conducive to communication with patients and colleagues, and is convenient for making detailed diagnosis and treatment plans for patients. It can judge the prognosis well and is also an important reference standard to judge the curative effect.

2. It can be used as the basic data for academic research, and also as an important data source for self-summary, self-learning, patient education and teaching materials.

3. Good oral photography can convey more accurate and intuitive aesthetic information to technicians, so that technicians can obtain more complete aesthetic design ideas.

4. In the environment of ruling the country according to law, oral photography is also an important means for doctors to protect themselves.

The factors affecting oral photography are as follows:

First, the aperture

1, the size of which is expressed by f value, and F= lens focal length ÷ lens effective aperture diameter.

2. The larger the F value, the smaller the aperture and the less the amount of light per unit time.

Second, the shutter speed

1, high-speed shutter solidification motion

2. The slow shutter increases the exposure and can capture the motion trajectory.

3. When taking photos with hands, the shutter speed should not be slower than the safe shutter speed of the lens (reciprocal of the focal length of the lens, for example,1100 second).

Third, sensitivity (ISO value)

It is inversely proportional to the image granularity and image quality. Low-sensitivity images have few rashes and delicate pictures, while high-sensitivity images have obvious rashes and poor image quality. The lower the ISO value, the better (generally 100).
