How is transillumination used?

The dental team uses transmitted light to examine the tooth and records what the method shows. The dentist then relates that finding to the visual examination and the clinical question.

[1][3]

What are the limits of the method?

Transillumination is a detection approach, not a complete treatment decision. Reviews of caries detection methods compare performance across methods and settings, so the finding needs careful interpretation.

[1][3]

Are other detection methods available?

Other methods, including fluorescence-based approaches, have also been studied for caries detection. The dentist selects the method that suits the tooth and the question under examination.

[1][2][3]

What does the result mean for me?

A transillumination finding is one piece of evidence for the dentist. It does not alone state how deep a lesion is or decide whether treatment is needed; those decisions follow the complete assessment.

[1][3]

Is transillumination cavity detection safe?

Transillumination is studied as a method for examining caries lesions. Ask the dental team what the method can show and how its finding will be combined with the rest of your examination.
