Answer.

Classification of Intraoral Radiography Films

Based on Use

Intra-oral films: Plated intraorally for imaging

• Periapical films
  • No 0 for children
  • No 1 for anterior adult projection
  • No. 2 for standard adult projection
• Occlusal films
• Bitewing films

Intraoral radiographic films

Based on the coating of the Emulsion

• Single coated: Produces better and sharper images, but exposure to the patient is higher.
• Double coated: Film consists of emulsion on both sides. Exposure to the patient is less.

Based on the speed of the Film

• Slow speed: Consists of very small grains of silver bromide, and the emulsion is on one side. The exposure required is more.
• Fast speed: Consists of a larger grain size, and the emulsion lies over both sides.
• Hyper speed G: It is an 800-speed film that halves the patient exposure without blurring the quality of the image.

Types of intraoral X-ray films

Based on Packaging

• Single film packet
• Double film packet

Barrier Envelops

• With barrier envelopes, it ensures that there is no gross contamination in the darkroom.
• Without barrier envelopes.

Bitewing periapical occlusal radiographs

Composition of Radiographic Film

X-ray film or intraoral X-ray film used in dentistry consists of four basic components:

• Film base
• Adhesive layer
• Film emulsion
• Protective layer
