Dental x-ray film

A photographic plate that captures an image after being exposed to x-rays, acting as an image receptor in dentistry.

Base of dental x-ray film

A sturdy yet flexible layer made of blue-tinted cellulose acetate that supports other layers and provides dimensional stability.

Sub-coating of dental x-ray film

An adhesive layer that ensures the emulsion firmly adheres to the base.

Emulsion Layer

The sensitive layer of the film containing silver halide crystals suspended in a gelatin matrix, which reacts to x-rays to form a latent image.

Supercoat

A protective layer of gelatin that safeguards the emulsion from scratches and damage.

Periapical films

Intraoral films that capture the entire tooth and surrounding structures, useful for diagnosing periapical pathology, caries, and periodontal diseases.

Bitewing films

Intraoral films focused on the crowns of upper and lower teeth, ideal for detecting interproximal caries and other restorations.

Occlusal films

Intraoral films providing broad views of the jaws, aiding in detecting fractures, lesions, and impactions.

Film speed

Also known as sensitivity; it determines how much radiation is needed to produce an image of standard density.

Lead foil backing

A layer in intraoral film packets that stiffens the packet and prevents backscattered radiation from fogging the film.
