Title: | Real-time measurement of internal stress of dental tissue using holography | Authors: | Dejan Pantelić Larisa Blažić Svetlana Savić-Šević Branka Murić Darko Vasiljević Bratimir Panić Ilija Belić |
Keywords: | holography;dental contraction;dental filling;LED illumination | Issue Date: | 28-May-2007 | Journal: | Optics Express | Abstract: | We describe a real-time holographic technique used to observe dental contraction due to photo-polymerization of dental filling during LED lamp illumination. An off-axis setup was used, with wet in-situ processing of the holographic plate, and consequent recording of interference fringes using CCD camera. Finite elements method was used to calculate internal stress of dental tissue, corresponding to experimentally measured deformation. A technique enables selection of preferred illumination method with reduced polymerization contraction. As a consequence, durability of dental filling might be significantly improved. © 2007 Optical Society of America. | URI: | https://open.uns.ac.rs/handle/123456789/15950 | DOI: | 10.1364/OE.15.006823 |
