DENTAL RADIOGRAPHY

Dental Radiography is a highly specialized field and used by every modern dental practice.

A radiograph is an exposed экспонтрованый and processed film also known as an X-ray negative. They are pictures of the teeth, bones, and surrounding soft tissues and they are made to identify possible problems with the teeth, mouth, and jaw.

X-rays can detect cavities, hidden dental problems, and bone loss that cannot be seen during a visual examination. Dental X-rays may also be done before treatment or as follow-up after dental treatment.

A dental X-ray is essential for virtually all DENTAL RADIOGRAPHY dental procedures. To produce suitable diagnostic radiographs the radiographer requires specialist knowledge of the teeth and oral cavity, as well as types of dental film, exposure settings, processing techniques, use of darkroom, and health and safety.

Dental film is supplied in different sizes and degree of sensitivity and each type of film has different exposure requirements in order to produce suitable radiographs for diagnostic purposes.

A radiographic image shows light and dark areas depending on the density of the material that the x-ray penetrates. Teeth appear lighter because less radiation penetrates them to reach the film. Cavities decay DENTAL RADIOGRAPHY, and other changes in the bone density appear darker because X-rays penetrate them easily. Fillings and other dental work may appear lighter or darker, depending on the density of the material used.

The radiation dose of an X-ray received by a dental patient is typically small. A lead shield, lead apron, and sometimes with a lead collar are used to reduce the patient’s exposure to radiation. The dental specialist reduces their exposure to radiation by going out of the room or by standing behind protective material when the X-ray is taken.

2. A dental X-ray is essential for virtually all dental procedures.

3. Dental film is supplied in different DENTAL RADIOGRAPHY sizes and degree of sensitivity.

4. The radiation dose of an X-ray received by a dental patient is typically small.

Exercise 9.Translate into your native language:

1. The basic procedure for taking a dental X-ray is to sit the patient down and adjust the headrest so that their head is in the correct position.

2. The patient is draped with a lead apron and a collar.

3. The film packet is inserted into the X-ray machine and the X-ray tube is aligned.

4. The correct exposure factor is selected and the exposure is then made.

5. The film is then sent DENTAL RADIOGRAPHY for processing.
