[Indications for and frequency of intraoral radiographs]

Radiographs are essential in dental practice today. Due to the exposure of patients to X-rays every radiograph has to be justified. The advantages and disadvantages of risks and diagnostic rewards have to be weighed against one another whenever X-ray imaging is considered. An important factor in this respect is the usefulness (in terms of sensitivity and specificity) of a radiograph and along with that, the monitoring of the quality of the entire process, from positioning the photo up to and including the development or scanning of it. Both for children and adults the indication for taking radiographs must be made on an individual basis. The most important considerations are: caries experience, oral hygiene and nutritional habits and exposure to fluorides. Based on these factors an individual risk assessment can be made and the possible benefit of bitewing radiographs for the dental treatment can be determined. European guidelines give advice on the indications and frequency of radiographs in, among other fields, periodontology, endodontology and implantology.
