Small knowledge about oral X-ray examination

Oral X-ray examination is to take pictures of diseased teeth with professional equipment. Why do we need oral X-ray examination? Because only part of our teeth are exposed, and the rest is covered by the gums, which requires X-ray examination to see.

Types, scope of application and advantages and disadvantages of oral X-ray examination

1. Small tooth film (apical film), suitable for the examination of single or local tooth lesions, used for the initial diagnosis of dental diseases. Its advantages are fast speed, small dose and short waiting time. The disadvantage is that some patients do not cooperate well and are not easy to operate.

2. Oral panoramic film (curved surface tomography), as a general screening examination method, is suitable for evaluating the health status of the whole mouth. Its advantage is that it can provide comprehensive information of the head, face and mouth. The disadvantage is two-dimensional imaging, and the image display has certain deformation.

3. Oral cone beam CT (CBCT), suitable for a wide range. The advantages are fast scanning speed, three-dimensional stereo imaging, can display tomographic images, and can find relatively subtle hard tissue lesions. The disadvantage is that there is a certain amount of radiation.
