Know More About Xray Films

X-RAY FILMS


Introduction
X-ray film is an image receptor.
It is a type of photographic film, in which an image is formed by
the exit radiation exposing the film.The film is composed of 2
principal components namely the base& emulsion.
Base:
0.2 mm thick & made up of clear, transparent cellulose acetate or
Cellulose nitrate.Cellulose acetate is used because it is less
inflammable. Recently polyesters [polyethylene teraphthalate] are
used.The base should be flexible for easy handling{manipulation}.
Emulsion:Consists of homogenous mixture of gelatin & silver
halide crystals.The gelatin is made from cattle bone.The gelatin is
clear so that it will transmit light & sufficiently porous to allow the
processing chemicals to penetrate it & reaches the silver halide crystals fast without affecting the strength.

Inferior alveolar nerve Part 2

  • for determining the location of the inferior alveolar nerve in all three dimensions of the mandible (lower jaw). With the software that is available to the dentist, the radiographic information from this study can be used to manipulate the jaw in 360° and provide the most accurate information to the dentist for treatment planning for the placement of the implant or for a third molar extraction. When screening radiographs demonstrate the increased risks for implant placement or third molar extraction, it is below the standard of care for the dentist or oral surgeon to fail to explain the
    advantages of the CT or CBCT as a diagnostic option to the patient before the patient is subjected to the increased risk of nerve injury. Continue reading →
