The aim of this in vitro study using implants and abutments was to examine traces left by various cleaning instruments and to determine the quantity of substance removal. The implants and relevant abutments were Screw-Vent implants (Dentsply), titanium plasma-coated full-screw implants (Straumann), and standard Brånemark implants (Nobel Biocare). The instruments used were titanium curettes, Gra...

This paper describes how to propagate approximately additive random perturbations through any kind of vision algorithm step in which the appropriate random perturbation model for the estimated quantity produced by the vision step is also an additive random perturbation. We assume that the vision algorithm step can be modeled as a calculation (linear or non-linear) that produces an estimate that...

PURPOSE This study was conducted to determine if tactile sensitivity varies in dental hygiene students who use the ultrasonic scaler, as compared to those who scale with hand-activated instruments. METHODS A two-group, randomized subjects, pretest-posttest design was carried out mid-semester for five weeks on 40 first-year dental hygiene students who met the inclusion criteria of this study a...

PURPOSE The use of appropriate instruments to clean surfaces with minimal change, is critical for the successful maintenance of a dental implant. However, there is no consensus about the type and methodology for such instruments. The aim of this study was to characterize changes in the roughness of titanium surfaces treated by various scaling instruments. METHODS Thirty-seven identical disks ...

This book focuses on developing cross-sectoral and cross-scaler solutions to assess mitigate risks water security across Asia the Pacific.

mean radioactivity in the serum was lower in both patients with pernicious anaemia and in control subjects, and the results in the patients with pernicious anaemia were more definitive. There was no significant difference between the results obtained with an Ekco scaler and those with an I.D.L. scaler. This is the simplest and most convenient method of measuring vitamin B12 absorption. It is su...

This paper presents an efficient method for the transmission of scalable video with error resilience over the Internet. We developed a Motion-JPEG2000-based software tool, called stream scaler, which can control the resolution levels and quality layers of codestreams to be adapted to end-user device requirements and to different bandwidth capacities. To analyze the performance of the stream sca...
