Dental Assistant Test 3 Questions With
Solutions 100% Solved
Density Degree of darkness in an image
High Density Little light to pass your eyes
Low Density Allow almost all of the transmitted light to be passed through it
Radiopaque do not permit the passage of radiation
Radiolucent tissues are less dense and do not permit the passage of radiation
Horizontal/vertical Bitewings Record crowns, alveolar crest and interproximal areas of
teeth
PA( Periapical ) Supporting structures of the teeth detects abnormalities of individual teeth
