A review on optical methods to assess dental behavior under stress: review

Abstract : This paper proposes a review of the different opportunities described in literature for quantitative assessment of natural and reconstructed teeth using optical methods. These experimental method are particularly interesting for understanding the behavior of the natural tooth, but even more so for the CAD/CAM (Computerized aided design and computerized aided manufacturing) bonded ceramics reconstructions. Indeed CAD/CAM ceramics are increasingly used as therapeutic options. However, little is known about their mechanical behavior under stress, as the response of the prepared tooth supporting it. In the past years, optical approaches were proposed to get whole field and quantitative measurement of their mechanical properties. This paper discusses the main methods described in literature, as photo elasticity, digital Moiré interferometry, speckle interferometry and digital color holography.
