Is the radiation from dental x-rays harmful to the body?
Although it is necessary to avoid receiving unnecessary X-rays as much as possible, it should be noted that the dose of radiation caused by dental x-ray examinations is very low, and on the other hand, the use of lead thyroid protectors and lead apron protects against of vital organs.
Usually, how often is there a need to prepare radiographs?
Caries of the interdental surfaces may not be detected clinically until they have reached their advanced stage, and periodic bitewing radiographs are recommended to detect these caries, but the interval between these radiographs depends on age, medical condition, diet Food, oral and dental hygiene and the spread of caries in the patient are determined.
Do metal ornaments in the cervical region have an effect on the quality of radiographs?
Metal ornaments such as (earrings, necklaces, and headbands) create an image on extraoral radiographs and make them unusable and thus repeat the radiograph, so metal ornaments in the head and neck area must be removed before performing radiography. CBCT metal devices cause artifacts and should be removed.
Should a thyroid protector be used during radiography?
The thyroid gland may be exposed to X-rays during intraoral radiographs, and therefore a protective lead thyroid collar should be used when preparing intraoral radiographs. However, when preparing extra-oral radiographs such as panoramic and cephalometric, you cannot use a thyroid shield because it prevents the radiation from reaching the chin and lower jaw bone.
