Dental radiographs, also known as dental X-rays, are important diagnostic tools in pediatric dentistry. Dental radiographs allow the dentist to see and treat problems like childhood cavities, tooth decay, orthodontic misalignment, bone injuries, and bone diseases before they worsen. These issues would be difficult (in some cases impossible) to see with the naked eye during a clinical examination.
The American Academy of Pediatric Dentistry (AAPD) approves the use of dental radiographs for diagnostic purposes in children and teenagers. Although radiographs only emit tiny amounts of radiation and are safe to use on an occasional basis, the AAPD guidelines aim to protect young people from unnecessary X-ray exposure.
What are dental X-rays used for?
Dental x-rays are extremely versatile diagnostic tools. Some of their main uses in pediatric dentistry include:
- Assessing the amount of space available for incoming teeth.
- Checking whether primary teeth are being shed in good time for adult teeth to emerge.
- Evaluating the progression of bone disease.
- Monitoring and diagnosing tooth decay.
- Planning treatment (especially orthodontic treatment).
- Revealing bone injuries, abscesses, and tumors.
- Revealing impacted wisdom teeth.
