WebConclusions: The 3D optical profilometry technique was able to provide accurate qualitative and quantitative assessment of changes on the enamel surface after debonding. Clinical relevance: Morphological changes in the topography of dental surfaces, especially if related to enamel loss and roughness, are of considerable clinical importance. WebOptical Profiling. If you need to characterize features at micrometre to sub micrometre on natural or manufactured surfaces, an optical profilometer will provide 3D surface metrology without any – potentially destructive – surface contact. This is a crucial advantage of optical profilometry over tactile (stylus-based) techniques. ravnsborg impeachment live stream
