1

Ionization

The harmful effect of X-ray beans in humans that results in a disruption of cellular structure and causes permanent damage to living cells and tissues.

2

Latent Period

Interval between exposure to ionizing radiation and the appearance of symptoms.

3

F-Speed Film

Currently the fastest exposure to ionizing radiation.

4

Digital Image

Electric representation of a radiograph, a film, or an X-ray image.

5

Radiograph

Image produced on conventional dental film.

6

Vertical Angulation

Angle measured within the vertical plane at which the central ray of the X-ray beam is projected.

7

Horizontal Angulation

Position of the tube head and the direction of the central ray in a horizontal or side-by-side plane.

8

Apex

Tapered end of each root tip.

9

Periapical

Apex and the surrounding area of the tooth.

10

Radiolucent

Image on a radiograph that appears in ranges from shades of gray to black.

11

Radiopaque

Image on a radiograph that appears in ranges from shades of light gray to total white or clear.

12

Contrast

Differences in the degrees of blackness on a radiograph.

13

Tube head

Tightly sealed, heavy metal housing that contains the radiograph.

14

Density

The overall blackness of darkness on a radiograph.

15

Panoramic

Provides a wide view of the upper and lower jaw.

16

Cephalometric

Extoral radiograph exposed to show the bones and soft tissue areas of the facial profile.

17

Collimation

Limiting the diameter of the X-ray beam to protect adjacent areas from exposure to radiation.

18

Filtration

Use of aluminum filters to remove long (less penetrating) wavelengths from a primary x radiation beam.

19

Bite-Wing

Shows images of the crowns of the teeth on both arches on one film.
