Concave - lingual

Convex - labial/facial

18
Q

What is the difference between labial and lingual mounting? and which is more popular?

A

Labial is the viewpoint of looking at a patient (most popular)

Lingual is the viewpoint from inside the patients mouth

19
Q

A

2% or 2degrees radiation

20
Q

What is the name of variety of energy wavelengths called?

A

Polychromatic beam

21
Q

What is the purpose of the lead foil and black paper in a film packet?

A

Lead foil in film protects the patient from back scatter radiation

Black paper protects film from light exposure
