Radiography Applications in Dentistry

“The point we pay the most attention to when taking radiography is the ALARA (As Low As Reasonably Achievable) principle, which is based on the principle of obtaining the highest quality image that can be taken with the least dose that can be given. Radiography applications such as panoramic and periapical x-ray, dental volumetric tomography are used in many areas of dental practice in order to make a correct diagnosis. Thanks to these images, we have the opportunity to see and interpret intra-osseous lesions, the condition of tooth roots, anatomical and pathological formations that we cannot see with intraoral examination. In addition, we use X-ray images to detect bone loss caused by gingivitis and to diagnose and evaluate the depth of caries in the interfaces.
 
Due to the use of x-rays in these radiographs, there is a risk of ionizing radiation. However, these doses are approximately 0.001 mSv for periapical x-ray and approximately 0.003 mSv for panoramic x-ray. Considering that this dose is 1 mSv for members of the community, the radiation dose received by imaging methods used in dental practice is far below the annual allowable doses. Considering the benefits it provides, there will be no harm in taking a panoramic radiograph every six months.
