ABSTRACT

Optical coherence tomography (OCT) is a noninvasive technique providing cross-sectional images of a tooth structure. This review describes the use of OCT for detecting dental caries, tooth fractures, and interfacial gaps in intraoral restorations. OCT can be a reliable and an accurate method and a safer alternative to X-ray radiography.

Clinical assessment of resin composite restoration. a Buccal view. Class V composite restoration was present with slight marginal discoloration but without any clinical symptoms. SS-OCT observation was performed along the red line. b SS-OCT image at red line in (a). Distinct white border between resin and enamel/dentin indicates “gap” (red arrow)

Mentions: Strong reflection from the material surfaces appears to be effective in conventional OCT setups for detecting the reflective signal from the fault, e.g., the border of cavitated caries, tooth fractures, and interfacial gaps of tooth restorations [13••, 17••, 18–20, Figs. 1, 2, and 3]. In addition, several lines of evidence report that the reflectivity of smooth surface caries lesions can be distinguished against sound enamel with OCT without polarization sensitivity, and the lesion contrast can be evaluated by post acquisition image processing [22, 29, 30, 32, 33•, 51–54].Fig. 1
