Digital imaging has become an important part of modern dental practice. Depending on the patient's needs, dental professionals may use photographs, digital radiographs or other imaging methods to gather information that cannot be obtained from a visual examination alone.
What is digital dental imaging?
Digital dental imaging refers to technologies that capture and display images of the teeth, supporting structures and surrounding oral tissues. Different methods provide different types of information, so the appropriate approach depends on the clinical question.
How digital radiography works
Digital dental radiography uses an electronic sensor to capture an X-ray image. The image can be viewed on a computer, helping the dental professional assess the relevant structures.
The image is only one part of the assessment. It must be interpreted alongside the patient's history, symptoms and clinical examination.
Why image quality matters
A useful image should show the structures required for the examination with sufficient clarity. Patient positioning, sensor placement and movement can affect image quality.
If an image does not provide the necessary information, the dental professional decides whether another image or a different examination method is appropriate.
Radiation safety and individual needs
Dental X-rays use ionising radiation, so imaging should be selected according to clinical need rather than performed automatically without consideration. Dental professionals follow applicable safety procedures and use imaging that is appropriate to the patient's circumstances.
Patients should tell their dental team about relevant medical circumstances and ask questions if they are unsure why an image has been recommended.
Technology supports, rather than replaces, clinical judgement
Digital tools can help organise records, display images and support communication. However, software and imaging systems do not replace a qualified professional's examination, interpretation or discussion with the patient.
