Detection and assessment of non-cavitated carious enamel lesions and tooth-restoration bond by Optical Coherence Tomography (OCT)

The major goal in dental treatment is oral health and maintenance of tooth structures. Therefor a modern caries management (prophylaxes) is necessary including all procedures to prevent new carious lesions (defects). Equally important is the detection and assessment of early carious lesions and monitoring of direct and indirect restorations (tooth-restoration bond). The noninvasive imaging OCT is a suitable approach for the representation of hard dental structures up to a depth of 2.5 mm. Former studies demonstrated that the detection of carious lesions and the assessment of tooth-composite bond are promising application areas of OCT in tooth preservation.
