Intraoral Radiography in Children

X-rays were discovered in 1895 by physicist Wilhelm Roentgen. He discovered that bones under his skin were visible when rays from a cathode tube passed through. Roentgen didn't know what was happening and labeled the rays "x", which gives us the term x-ray. X-rays are also known as radiographs. They are used frequently by dentists as a preventive and diagnostic tool in dental examinations. You should consider a few things when it comes to intraoral radiographs with children.

  1. Description

    • Two types of oral x-rays exist: intraoral and extraoral radiographs. Intraoral means the x-rays are taken from inside the mouth, while extraoral means they are taken from outside the mouth. Intraoral radiographs are the most common. Bite-wing, periapical, occlusal and full mouth x-rays are just a few of the intraoral radiographs used. Intraoral radiographs help dentists discover cavities, check tooth growth and development, monitor decay and check the boney area around the teeth.

    Age Recommendations

    • No specific age exists for when a child should get their first intraoral radiographs, but between the age of 5 and 6 is a fairly common age for the first x-ray. In addition to a child's age, a dentist will also consider the size of a child's oral cavity, his or her needs and any other special circumstances. Evidence of cavities or tooth decay, early trauma to the face or a cleft lip or palate are all reasons for a dentist to take intraoral radiographs earlier.

    Radiation Concerns

    • Dentists weigh the risks and benefits when it comes to taking intraoral radiographs on a child because of the radiation concerns. Children are more sensitive to radiation than adults, but dentists can reduce the risk by using protective techniques. Using a higher speed film, including digital radiographs, can lessen the exposure. Radiation exposure is measured in milligrays. A 1999 survey by the Nationwide Evaluation of X-Ray Trends showed that using F-speed film (faster) rather than D-speed film (slower) reduced exposure to radiation by 60 percent. Dentists will also use a lead apron and thyroid collar to reduce exposure.

    Frequency

    • The frequency of intraoral radiographs on children depends on their needs. For children with a high risk of tooth decay, the American Academy of Pediatric Dentistry recommends radiographs every six months. For children with a low risk of tooth decay, x-rays every 12 to 24 months is acceptable. Brushing and flossing regularly, using fluoride and keeping sugar intake down will all help lower the need for frequent intraoral radiographs.

    Tips

    • Going to the dentist and having intraoral radiographs is a scary experience for some children. Making sure the dentist and dental hygienist use a "tell/show/do" approach will help alleviate fear in your child. This means they will tell the child about the procedure, then show them equipment or even demonstrate using the equipment on a parent and then actually complete the procedure on the child. Use simple words when talking to your child about any part of the process. Make sure you use positive reinforcement and stay calm throughout the dental visit. Use distractions when necessary to keep a child's attention off the procedure.
