LESSON 5 Digital Imaging, Dental Film and Processing Review

These flashcards cover key concepts related to digital imaging and dental film processing, including film types, processing steps, and the purpose of various radiographic tools.

What type of film will improve the sharpness of a radiographic image?

SMALLER FILM CRYSTAL SIZE

Where should the plain side of dental film be placed during placement?

TOWARDS THE TUBE AND DOT PLACED TO THE OCCLUSAL OR INCISAL OF THE TOOTH. LABEL FACES TONGUE

What is the purpose of extraoral radiographs?

TO EXAMINE LARGE AREAS OF THE HEAD OR JAW. PLACED OUTSIDE OF THE MOUTH DURING X-RAY EXPOSURE

What does a panoramic film show?

A PANORAMIC VIEW OF UPPER AND LOWER JAWS ON A SINGLE RADIOGRAPH.

What must always face the patient during exposure in extraoral radiography?

FRONT SIDE OF CASSETTE MUST ALWAYS FACE THE PATIENT

What does an intensifying screen do in radiography?

IT INCREASES THE EFFECTS OF RADIATION AND DECREASES THE AMOUNT OF EXPOSURE TIME NEEDED

What is the primary type of exposure for duplicating radiographs?

Duplicating radiographs is exposed only to light. FILM IS LIGHT SENSITIVE 

What does the emulsion of the duplicating films not appear when exposed to light?

SHINY

Where should unopened boxes of dental film be stored for safety?

IN DARKROOMS

What is the purpose of the developer in film processing?

The developer chemically reduces the exposed silver halide crystals to BLACK metallic silver AND softens the FILM EMULSION

What does the acidic fixing solution do during film processing?

The acidic fixing solution removes the unexposed silver halides from the film emulsion AND HARDENS IT DURING PROCESSING

How long does automatic film processing typically require?

ITS FAST, SO IT REQUIRES ONLY 2-6 MINUTES

What may cause processing errors in film developing?

TIME AND TEMPERATURE

CHEMICAL

FILM HANDLING

LIGHTING

What should a dental assistant be able to recognize?

must recognize the appearance of common processing errors and prevent problems from occuring again

What's the correct order for manual film processing?

1. DEVELOP- 5MIN

2. RINSE- 20 SECOND

3. FIX- 10 MIN

4. WASH- 20MIN

5. DRYING-30SECONDS

what is the recommended distance between the safelight and where the film are unwrapped?

4 ft

When loading the film into the cassette before exposure in extraoral radiography, the procedure must be done in the?

DARKROOM
