Comparison between a profilometer and a measuring microscope for measurement of enamel erosion.
The aim of this study was to measure the difference in the erosion depth of enamel measured by profilometry (PM) and a measuring microscope (MM). Sixty enamel specimens were divided into ten groups. Each specimen group was exposed to 50 ml of a carbonated drink with pH 2.38 or orange juice with pH 3.67 for 15, 30, 60, 120, and 180 minutes. Depths of eroded areas were measured with a profilomete...
متن کاملGingival Thickness Assessment: Visual versus Direct Measurement
Background and Aim: Several methods have been suggested to measure gingival thick-ness. This study aimed to assess the reliability of visual assessment of facial gingival biotype of maxillary and mandibular teeth with or without using a periodontal probe in comparison with direct measurement. Materials and Methods: Sixty-seven healthy patients (25 women and 42 men) with a total of 100 hopele...
متن کاملNovel reflected light confocal profilometer
We present an instrument that uses a novel technique to render topographical maps of microscopic reflecting surfaces in which depth resolution can be an order or magnitude or more better than the lateral resolution of the confocal microscope. In a confocal scanning reflected-light microscope, the illumination light coming out of the objective is a cone of light with its axis parallel to the opt...
متن کاملA Fast Versatile Optical Profilometer
The surface quality of a workpiece, as it is finished by the tooling machine, can be translated into a set of numbers (one or more) which depend on the specific measuring procedures. We illustrate this with respect to the three classes of profilometer techniques either available or suggested, namely: mechanical profilometers, detection of the angular scattering diagram, speckle correlation. A m...
متن کاملSea-Ice Thickness Measurement:
Helicopter-borne electromagnetic (HEM) induction systems provide a means to measure sea ice thickness along flight paths covering a large area in a short period of time, and make the data available in real-time for incorporation into operational ice charts. Ice surface elevation profiles are also collected with a laser altimeter contained in the system. With the introduction of the fix-mounted ...
