“…Consequently, experimental tests need to be carried out to investigate the constraints imposed on the bonded restorations [7][8][9][10] , and to estimate interface problems in adhesive reconstructions caused by PSS 10,11 . On the other hand, direct monitoring of secondary phenomena, such as tooth cusps deflection, can provide indirect vision into PSS development [12][13][14][15][16] .…”

Background/Aim. The objective of this study was to measure tooth cusps deflection caused by polymerization shrinkage of a resin-based dental material (RDM), in real-time using digital holographic interferometry (DHI), in two groups of cavities restored with and without an additional wall. Simultaneously, internal tooth mechanical behavior was monitored. Methods. Standardized three class I cavities were prepared on third molar teeth. The teeth were cut in two halves in the longitudinal plane, obtaining six samples for the study (now with class II cavities), divided into two groups (group G1 - with the additional wall, group G2 - without it) and mounted in aluminum blocks. The cavities were filled with the RDM, cured with a light emitting diode (LED) for 40 s from the occlusal direction, and monitored during the curing and post-curing period using DHI. Data were analyzed using student's t-test for independent samples and Anderson-Darling test, with an alpha level of 0.05. Results. At the end of the examined period, the samples from group G1 showed significantly increased tooth cusps deflection (t (10) = 4.7; p = 0.001) compared to samples from group G2. Conclusion. Within the limitations of this study, it was concluded that the presence of the additional wall simulating a dental matrix-band, influenced increased and prolonged tooth cusps deflection during the examined RDM polymerization shrinkage.

The field of speckle metrology has seen a surge in development in the past 10 years owing to advancements in digital cameras and computing power. For instance, a variety of digital speckle correlation (DSC) processes can now be performed in almost real time and therefore speckle techniques has found applications in nondestructive testing (NDT), biology, and medicine. New techniques in terms of optical arrangements and in extracting phase data have been introduced for measuring out‐of‐plane and in‐plane motions in digital speckle interferometry (DSPI) and digital speckle shear interferometry (DSSPI). DSC, DSPI, and DSSPI have also been combined to extend the range of measurements. In addition, quantitative analysis in speckle interferometry has seen a plethora of new software developments for conducting real‐time, accurate, complicated, fast, and repeatable measurements with ease. In addition, different methods to process speckle fringes have made analysis equivalent to that of classical interferometry, yet can be applied to all types of real‐world specimen.
