What is an open contact?

A

A radiolucent line between two adjacent surfaces.

15
Q

What are overlapped contacts?

A

The area where the contact area of one tooth is superimposed over the contact area of an adjacent tooth.

16
Q

What are areas where teeth are no longer present called?

A

Endentulous

17
Q

What is a right angle?

A

An angle of 90 degrees formed by two lines perpendicular to each other.

18
Q

What is a receptor holder?

A

A device that holds the receptor.

19
Q

How would you describe the long axis of a tooth?

A

An imaginary line that divides the tooth longitudally into two equal halves.

20
Q

What is the object-receptor distance?

A

The distance between the receptor and tooth.

21
Q

What is parallel?

A

Moving or lying in the same plane; always separated by the same distance and NOT intersecting.

22
Q

What is the paralleling technique?

A

A technique used to expose periapical receptors.

23
Q

What is the receptor placed parallel to in the paralleling technique?

A

The receptor is placed parallel to the long axis of the tooth.

24
Q

How is the central ray placed in conjunction with the receptor in the paralleling technique?

A

Perpendicular both the tooth and receptor.

25
Q

What does perpendicular mean?

A

Intersecting at a point or forming a right angle.

26
Q

What is target-receptor distance?

A

The distance between the source of the x-rays and the receptor.

27
Q

What teeth make up our anterior teeth?

A

Canines and Lateral/Central incisors.

28
Q

What teeth make up our posterior teeth?

A

Molars and Premolars

29
Q

What does it mean to bisect?

A

To divide something into two equal parts.

30
Q

What is the bisecting technique?

A

A method used to expose periapical images.

31
Q

What is an imaginary bisector?

A

A plane that the radiographer must visualize that divides the angle formed by the receptor and long axis of the tooth in half.

32
Q

What is elongation?

A

When an image appears too long.

33
Q

When does elongation occur?

A

When the vertical angle is too flat.

34
Q

What is foreshortening?

A

When an image appears short.

35
Q

When does foreshortening occur?

A

When the vertical angle is too extreme.

36
Q

What is an occlusal projection?

A

An intraoral radiographic examination used to examine the buccal and lingual aspects of the mandible and locate foreign bodies.

37
Q

40
Q

What is the buccal object rule?

Hint: “Slob”

A

When the horizontal angulation of the PID is moved mesial and the object in the image moves the same direction it is lingual if it is buccal it will move in the opposite direction.
