Radiography technique

In general there is no scientific difference in the Radiography technique applied for the child and that for the adult patient, but there is a high probability of technical errors while taking radiographs for the child patients.

These errors caused by wrong Radiography technique may distract or destroy the radiographs diagnostic value. The most commonly observed Radiography technique errors are:

  • Improper placement of films.
  • Cone cutting
  • Incorrect horizontal angulation, for example in case of interproximal caries this improper angulation shows the overlapping of the contact area and makes the diagnosis impossible.
  • Improper vertical angulation projects the cap of the enamel of the crown over the inter proximal surface and obliterates the carious lesion
  • Over exposure due to defective devices.
  • A high exposure of the patient to radiation because of repetition of taking X-rays due to an uncooperative child.

Radiation hygiene measures:

It is imperative that the radiograph should be taken by following proper radiation hygiene measures. These measures are:

  • Proper registration of radiographic units
  • Proper maintenance of radiographic units
  • Training of personnel who are associated with radiography
  • Dosage monitoring
  • Radiation protection of the child patients by using lead apron with a thyroid collar
  • Use of long lead-lined cylinders and cone positioning devices
  • Use of electronically controlled exposure timer
  • Use of high speed films
  • Use of automatic processing machines that give good consistent results
  • Employing proper technique to avoid the chances of repeating the exposure.
  • Proper sterilization of objects used in radiography that can get contaminated by the patient’s saliva.
