Dental X-ray is a diagnostic tool in dentistry. By analyzing the X-ray image and conducting a clinical examination, we can evaluate overall oral health, establish a diagnosis, and develop a treatment plan.
When Is a Dental X-ray Needed?
X-rays are mandatory in situations such as root canal procedures, tooth extraction, crown and bridge placement, and during orthodontic therapy.
Types Of Dental X-rays
Depending on the part of the tooth or jaw we wish to examine, there are various dental X-rays. At Dr. Bede’s dental clinic, we perform periapical X-rays, which are targeted X-rays of individual teeth, most often required during dental restoration or treatment. This allows us to complete the diagnosis and treatment within the same appointment. Other types of X-rays can be performed at dental imaging centers.
Periapical X-rays
This type of X-ray, also called a targeted X-ray, allows for a more precise assessment of each tooth. It is used in the following situations:
- To determine if there is tooth decay.
- To assess whether there is chronic nerve inflammation with a lesion at the root tip.
- To evaluate the condition of a tooth after trauma.
- During root canal procedures, assess the tooth roots’ condition and evaluate the final canal filling.
Panoramic X-ray (OPT)
An orthopantomogram (OPT or orthopan) is an X-ray showing both the upper and lower jaws in their entirety, along with the surrounding bone structures. It provides a two-dimensional view of the entire jaw apparatus and can be produced on film or in digital format on a CD.
This X-ray is used to evaluate the general health of the oral cavity, but it is not precise enough for assessing the condition of individual teeth. The panoramic X-ray can show:
- The position of erupted and unerupted teeth in the jaw.
- The surrounding bone, presence of pathological lesions, or periodontal pockets.
- Bone health and pathological changes in the jaw.
- The proximity of sinuses to upper teeth and pathological changes in the sinuses.
- Bone condition after dental procedures (extractions, implant placement).
- The presence of focal issues in the oral cavity for patients preparing for surgery, radiation, or chemotherapy.
3D Dental X-ray
This type of X-ray is not used routinely but only when a more precise assessment or measurement of jaw structures is required. This X-ray allows for magnification and measurement of all bone structures.
It is used after dental treatment when assessment with only a periapical X-ray is insufficient. Patients planning implant placement must have a 3D X-ray of the jaw to precisely determine the implant’s location.
Bitewing X-ray
This type of X-ray is a diagnostic tool for detecting cavities. It shows only the crowns of 3-4 adjacent teeth in both jaws. This X-ray does not provide a full assessment of the surrounding bone and tooth roots.
What Does The Dental X-ray Procedure Look Like?
The procedure varies depending on the type of X-ray. For periapical or bitewing X-rays, the film is placed inside the mouth for imaging. All X-ray procedures are completely painless and very quick. Radiation protection is mandatory during the process.
Cost Of Dental X-rays
The cost depends on the type of X-ray. The price of a periapical X-ray used during dental treatments is 500 RSD.
Frequently Asked Questions
Is dental X-ray safe?
Dental X-rays are completely safe when certain rules are followed. Radiation protection during the procedure is mandatory. Pregnant women should avoid X-rays throughout their pregnancy.
When is each type of dental X-ray used?
Periapical (small) X-rays are used during dental treatments. Panoramic X-rays are most often used to assess overall dental health, including teeth roots and surrounding bone.
How long is a dental X-ray valid?
Panoramic X-rays are valid for about a year, while periapical X-rays can be taken more frequently as needed.
