Dentistry radiography

What is the principle of dental radiography?
There are three key principles—time, distance and shielding.
All three should be applied for each x-ray exposure.
Time is straightforward—the longer you are exposed to a radiation source, the greater the radiation dose you receive..

A radiographic image is formed by a controlled burst of X-ray radiation which penetrates oral structures at different levels, depending on varying anatomical

Clinical index that allows dentists to measure facial alveolar bone in the horizontal or axial plane

The radiographic supporting bone index (RSBI) is a clinical index that allows dentists to measure facial alveolar bone in the horizontal or axial plane.
It enables orthodontists and dentists placing dental implants, or completing esthetic dentistry, to accurately determine the amount of facial alveolar bone available before initiating treatment.
Prior to the development of this index, orthodontists and dentists faced a serious risk of inducing iatrogenic gum recession following treatment.
