RESUMO

This work reports the application of optical coherence tomography (OCT) to generate image of remaining dentin and pulp chamber of in vitro human teeth. Bi-dimensional images of remaining dentin and of the pulp chamber were obtained parallel to the long axis of the teeth, by two OCT systems operating around 1280nm and 850nm, and compared with tomography images using the i-CATÂ Cone Beam Volumetric Tomography system as the gold standard. The results demonstrated the efficacy of the OCT technique; furthermore, the wavelength close to 1280nm presented greater penetration depth in the dentine than 850nm, as expected from scattering and absorption coefficients. The OCT technique has great potential to be used on clinical practice, preventing accidental exposure of the pulp and promoting preventive restoration treatment
