Abstract
Caries of the interdental space are usually difficult to detect with conventional bitewing radiography. We have developed an interdental probe for polarization-sensitive optical coherence tomography (PSOCT) that can distinguish between healthy and carious tooth structures. The development is based on a fiber optic probe with a compact motor design that allows volumetric imaging. In a clinical study, demineralization was detected using proximal PSOCT scans of premolars and molars, and compared with blind diagnoses from four dentists. The results show that PSOCT can detect both, early demineralization and advanced proximal caries, some of which could not be diagnosed with bitewing radiography.
