Oral and maxillofacial radiology is a specialized branch of dentistry where diseases, anomalies, and pathological formations in and around the oral cavity are diagnosed and treatment plans are developed using clinical and radiological methods. Oral and maxillofacial radiology enables the detection of intraosseous lesions, root apex infections, and impacted teeth that are not visible to the naked eye, using imaging technologies.
What is Oral, Dental and Maxillofacial Radiology?
Oral and maxillofacial radiology is a fundamental branch of dentistry that uses X-rays and other imaging techniques to examine the structures of the mouth and face in detail. It helps dentists determine the appropriate course of treatment.
Dental alignment provides critical data about jawbone density and soft tissue health. Oral, dental, and maxillofacial radiology is particularly important for the early diagnosis of early-stage dental caries, cysts, and bone loss.

What diseases does Oral, Dental and Maxillofacial Radiology treat?
Oral and maxillofacial radiology encompasses a broad range of diseases affecting the mouth and surrounding tissues. Following the diagnostic process, patients are referred to appropriate treatment departments (such as surgery, prosthetics, or orthodontics). Conditions examined and diagnosed in the oral and maxillofacial radiology department include the following:
- Impacted tooth:Specifically, the position of wisdom teeth within the jawbone and their proximity to nerves are important factors.
- Jaw cysts and tumors: These are asymptomatic (non-symptomatic) formations that develop within the bone.
- Symptoms of oral cancer: These are color changes and texture irregularities seen on the mucous membranes.
- Temporomandibular joint disorders: These are problems with the chewing muscles and joint discs.
- Salivary gland diseases: These can be stones, blockages, or inflammations in the salivary glands.
- Bone loss and bone destruction: These are the losses of supporting tissue that develop due to gum disease.
What are the diagnostic methods in Oral and Maxillofacial Radiology?
Radiological methods used in oral and dental health vary according to the patient's needs and complaints. Today, the use of digital systems has minimized the amount of radiation exposure while improving image quality. The main imaging technologies used in the Department of Oral and Maxillofacial Radiology are as follows:
- Periapical X-ray: These are small films that show the most detailed view of a single tooth and the surrounding bone tissue.
- Panoramic X-ray: It is a general screening method in which all teeth, upper and lower jaw bones, sinuses, and joints are seen in a single film.
- Dental CT scan (CBCT): It is an advanced technological method used before implant and surgery that allows for three-dimensional (3D) examination of the region.
- Cephalometric X-ray: It is generally used to measure the ratio of skull bones to teeth before orthodontic treatment.
Digital Dental Tomography (CBCT) Technology
Cone-beam computed tomography (CBCT) creates a volumetric image by taking millimeter-sized cross-sections of the oral and jaw region. Unlike standard two-dimensional X-rays, dental tomography offers depth perception, minimizing the margin of error.
In implant planning, bone volume measurement, visualization of the nerve canal, and analysis of root anatomy in complex root canal treatments are indispensable diagnostic methods. Compared to traditional tomography, it provides high-resolution data with a much lower radiation dose.
Frequently Asked Questions Regarding Oral, Dental, and Maxillofacial Radiology
Is it safe to get a dental X-ray?
Digital radiography technology results in very low radiation doses, and the risk is minimized with the use of protective gowns.
Can pregnant women have dental X-rays?
In cases of necessity, imaging can be performed with the approval of an obstetrician and with special protective equipment (vest and neck brace), but it is recommended to avoid it in the first trimester.
Why are panoramic dental X-rays necessary?
It is a standard screening procedure to visualize cysts that are not visible to the naked eye, impacted teeth, and anomalies in the jawbone as a whole.
In what situations is a digital tomography scan performed?
Digital tomography is used to visualize the bone structure in 3D for implant planning, impacted tooth surgeries, and temporomandibular joint (TMJ) problems.
Do I need to go to the examination on an empty stomach?
Fasting or food intake is not required for oral, dental, and maxillofacial radiology examinations and imaging procedures.
How long does a radiological examination take?
Panoramic shots take approximately 15-20 seconds, while periapical shots take only a few seconds; the results are instantly displayed on the digital screen and given to the patient.
Can children have dental X-rays?
Tooth extraction can be performed on children using low-dose settings in cases of tooth eruption monitoring, missing tooth detection, or trauma.
Are panoramic X-ray machines available at every dentist's office?
Panoramic X-rays are a technology typically found in fully equipped medical centers, dental hospitals, and clinics with radiology departments; they are not available at every dentist's office.
