X-rays are often used in pediatric dentistry and for a variety of reasons too. Radiography or what is known as “conventional x-ray” is a particular type imaging technique in medicine used to aid pediatric dentistry, this means that an image is recorded and used for subsequent evaluation.
Dental x-rays in children are important. With the appropriate precautions taken, pediatric radiography is considered to be a very low-risk thing and poses a low risk of adverse health effects, and there exist many reasons why the advantages of dental X-ray outweighs the risk.
Problems of dental x-ray for children
Because children are much more sensitive to the exposure of radiation than adults, the risk of cancer per unit dose of X-ray is quite higher in children than in adults.
It is not the radiation of a single x-ray or radiography that causes cancer, it is the accumulation of exposure to radiation over a long period of time. The smaller a child, if he has an X-ray, the more time he has for the manifestation of the effect of radiation as cancer.
Modern X-ray equipment should rather be used because they have configurations and setting that allow the proper X-ray dosage for younger children.
The type of x-ray depends on the image sought for by the dentist, he can order for different types of X-rays. Here are some types:
Bitewing X-rays: Bitewing X-rays are used in searching for cavities in between the teeth that would otherwise be difficult to see. They can be used too to check for past fillings due to wear and tear.
Periapical x-rays: these are enlarged x-rays with one or more teeth and they show the entire tooth of the individual from the crown down to the root. These X-rays may be used to search for issues with the root of the tooth or jaw and the surrounding cavities.
Panoramic X-rays: Panoramic X-rays may be used to check the development of a child’s teeth to see if orthodontics is needed. The X-ray may also be used to observe emerging teeth, tumors or impacted teeth.
