The aim of this study was to see the effect of Er:YAG laser irradiation in dentine and compare this with its effect in enamel. The mechanism of crack propagation in dentine was emphasised and its clinical implications were discussed. A possible mechanism is that laser radiation is transmitted down the dentinal tubules causing micro-cracks to form in the dentinal tubule walls that tend to be limited to this region. Crack might be a source of fracture as it represents a weak point and subsequently might lead to a failure in restorative dentistry.
Three-dimensional segmentation and analysis of the specimens were performed using Avizo software (version 9.2.0). The data was filtered using a non-local means filter with a kernel size of 21. Segmentation of the cracks was performed predominantly manually.
