History of Radiography
A photographic image produced on a receptor by the passage of x-rays through teeth and related structurees.
What is a RADIOGRAPH
The receptor that is placed inside the mouth
What is INTRAORAL ?
The horizontal bitewing will be used to deteect_______ caries.
What is INTERPROXIMAL ?
Which part of the tubehead prevents it from overheating
What is INSULATING oil?
Which form of interaction in x-ray production occurrs 62% of the time
Wha tis COMPTON SCATTER?
A beam of energy that has the power to penetrate substances and record image shadows on a photographic film
What is X-RAY
The component of the dental x-ray machine that allows movement and positioning of the tubehead
What is EXTENSION ARM?
