Comparison of alphanumeric notation, Palmer notation, ISO 3950 (FDI) notation, Universal Numbering System, and paleoanthropology notation. Dental professionals, in writing or speech, use several different dental notation systems for associating information with a specific tooth.
Comparison of alphanumeric notation, Palmer notation, ISO 3950 (FDI) notation, Universal Numbering System, and paleoanthropology notation. Codes, names, and usual number of roots: (see chart of teeth at Universal Numbering System) 11 21 51 61 maxillary central incisor 1; 41 31 81 71 mandibular central incisor 1; 12 22 52 62 maxillary lateral ...
Dental radiographs, commonly known as X-rays, are radiographs used to diagnose hidden dental structures, malignant or benign masses, bone loss, and cavities.. A radiographic image is formed by a controlled burst of X-ray radiation which penetrates oral structures at different levels, depending on varying anatomical densities, before striking the film or sensor.
The x-ray film represents a two-dimensional image of a three-dimensional object due to the summary projection of different anatomical structures onto a planar surface. It requires certain skills for the correct interpretation of such images. Radiological anatomy is a necessary component of training for medical students and radiologists.
Radiography is an imaging technique using X-rays, gamma rays, or similar ionizing radiation and non-ionizing radiation to view the internal form of an object.Applications of radiography include medical ("diagnostic" radiography and "therapeutic radiography") and industrial radiography.
X-ray attenuation of CBCT acquisition systems currently produces different HU values for similar bony and soft tissue structures in different areas of the scanned volume (e.g. dense bone has a specific image value at the level of the menton, but the same bone has a significantly different image value at the level of the cranial base).
Cephalometric analysis depends on cephalometric radiography to study relationships between bony and soft tissue landmarks and can be used to diagnose facial growth abnormalities prior to treatment, in the middle of treatment to evaluate progress, or at the conclusion of treatment to ascertain that the goals of treatment have been met.

In radiology, an X-ray image may be said to be "anteroposterior", indicating that the beam of X-rays, known as its projection, passes from their source to patient's anterior body wall first, then through the body to exit through posterior body wall and into the detector/film to produce a radiograph. The opposite is true for the term ...
