Introduction:

Dental X-rays (radiographs) are images of your teeth that your dentist uses to evaluate your oral health. These X-rays are used with low levels of radiation to capture images of the interior of your teeth and gums. This can help your dentist to identify problems, like cavities, tooth decay, and other impacted teeth.

Dental X-rays may seem complex, but they’re actually very common tools that are just as important as your teeth cleanings. Dental X-rays are typically performed yearly. They can happen more often if your dentist is tracking the progress of a dental problem or treatment.

Factors affecting how often you get dental X-rays done may include:

  • Your age
  • Your current oral health
  • Any symptoms of oral disease
  • A history of gum disease or tooth decay

Children may need to have dental X-rays more often than adults because their dentists might need to monitor the growth of their adult teeth. This is important because it can help the dentist determine if baby teeth need to be pulled to prevent complications, such as adult teeth growing in behind baby teeth.

2D and 3D X-ray Technologies

Two-dimensional and 3D X-ray technologies are among the most useful non-destructive testing methods. They enable the inspection of an object’s internal features without having to disassemble the sample or destroy the part in the process. Several X-ray based technologies began in medicine and then found use in industrial applications. Today, X-ray technologies are increasingly being used in the quality control industry for non-destructive analysis and 3D imaging in industries such as aerospace, automotive, electronics, medical devices, plastic components, and 3D printing (additive manufacturing).

Importance of full mouth X-Ray

A dental radiograph gives your dentist a picture of your hard tissues (teeth and bones) and the soft tissues that surround your teeth and jawbones. For example, dental radiographs may help your dentist see diaries (tooth decay) that develops between the teeth or under restorations (fillings); diseases in the bone; periodontal (gum) disease; infections that develop under your gums; some types of tumors. Dental radiographs can alert your dentist to changes in your hard and soft tissues. In children, radiographs allow the dentist to see how their teeth and jawbones are developing. Like medical radiographs, dental radiographs allow your dentist to evaluate any injuries to your face and mouth. Dental radiographs can help your dentist identify diseases and developmental problems before they become serious health issues. Early detection of an infection or injury also can limit or prevent further damage to other areas of the mouth.

Factors about which we focus seriously

While dental X-rays do involve radiation, the exposure levels are so low that they’re considered safe for children and adults. Many clinics use digital X-rays instead of developing them on film to reduce risks from radiation exposure to patients.

Clinics also place a lead “bib” over the patient's chest, abdomen, and pelvic region to prevent any unnecessary radiation exposure to the vital organs. A thyroid collar may be used in the case of thyroid conditions. Children and women of childbearing age may also wear them along with the lead bib.

Pregnancy is an exception to the rule. Women who are pregnant or believe they may be pregnant should avoid all types of X-rays. Tell the dentist if you believe you are pregnant, because radiation is not considered safe for developing fetuses.

Preparation before dental X-rays

Dental X-rays require no special preparation. The only thing you’ll want to do is brush your teeth before your appointment. That creates a more hygienic environment for those working inside your mouth. X-rays are usually done before cleanings.
