Gingival 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 کاملOn Designing of Membrane Thickness and Thermal Conductivity for Large Scale Membrane Distillation Modules
Membrane distillation has the potential to concentrate solutions to their saturation level, thus offering the possibility to recover valuable salts from the solutions. The process performance and stability, however, is strongly dependent upon the features of membranes applied. In addition, several other parameters, membrane thickness and thermal conductivity significantly affect the process per...
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 ...
متن کاملReal-time automated thickness measurement of the in vivo human tympanic membrane using optical coherence tomography.
BACKGROUND Otitis media (OM), an infection in the middle ear, is extremely common in the pediatric population. Current gold-standard methods for diagnosis include otoscopy for visualizing the surface features of the tympanic membrane (TM) and making qualitative assessments to determine middle ear content. OM typically presents as an acute infection, but can progress to chronic OM, and after num...
متن کاملCorrosion Monitoring and Thickness Measurement
INTRODUCTION During the last three years my interest in the use of ultrasonics for the detection of corrosion and the measurement of remaining wall thickness has been re-awakened. The method has been extensively used to verify and quantify Magnetic Flux Leakage (MFL) results. Discrepancies between ultrasonic and MFL results have usually been put down to "Another MFL false call." However, having...
