Abstract:
Fiber-optic transillumination (FOTI) is a well-accepted and valuable adjunctive diagnostic tool with a wide range of clinical applications. In dentistry, FOTI has been primarily associated with caries diagnosis and has been corroborated through research studies to be a valid indicator of the histological presence or absence of bacterially infected tooth structure. In this review, techniques for using FOTI for tooth evaluation are presented along with examples of how FOTI can be effectively used as a supplemental diagnostic aid.
