OBJECTIVE The aim of this study was to evaluate the susceptibility of dentin to brushing abrasion using four different toothbrushes (rotating-oscillating, sonic and two types of manual toothbrushes) with the same brushing forces. METHODS Dentin samples (n = 72) were selected from 72 impacted third molars. Half of the surface of dentin samples was covered with an adhesive tape, creating a prot...

Visualizing time-varying call graphs is challenging due to vast amounts of data at many dimensions to be displayed: Hierarchically organized vertices with attributes, directed or undirected edges with weights, and time. In this paper, we introduce a novel overview representation that shows dynamic graphs as a timelineand pixelbased aggregated view targeting the preservation of a viewer’s mental...

Interactive Visual Analysis has been widely used for the reason that it allows users to investigate highly complex data in coordinated multiple views, showing different perspectives over data. In order to relate data, multiple techniques of brushing have been introduced. This work extends the state of the art by introducing the Convex Hull (CH) Brush, which is a new way of selecting and interpr...

Users who must combine dcmographic, economic or other data in a geographic context are ofren hampered by the integration of tabular and n w p representations. Static, paper-based solutions limit the amount of data that can be placed on a single map or table. By providing an effective user interface, we believe that researchers, journalists, teachers, and students can explore complex data sets m...

Interaction in visualization is often complicated and tedious. Brushing data in a visualization such as parallel coordinates allows the user to select data points according to certain criteria; modifying a brush requires a lot of effort and mode switches. We propose the use of multi-touch interaction to provide fast and convenient interaction with parallel coordinates. By using a multitouch tra...

In visual analytics, interactive data visualizations provide a bridge between analytic computations, often involving “big data”, and computations in the brain of the user. Visualization provides a high bandwidth channel from the computer to the user by means of the visual display, with interactions including brushing, dynamic queries, and generalized fisheye views designed to select and control...

Dentifrice abrasiveness and brushing time may increase color change (∆E) and surface roughness (∆Ra) of resin composites. This study aimed to evaluate the effect of mechanical brushing time of dentifrices with different abrasiveness on ∆E and ∆Ra of nanofilled (Z350, 3M ESPE) and nanohybrid (Tetric N-Ceram, Ivoclar Vivadent) resin composites. Sixteen specimens (12 mm diameter x 2 mm thick) were...

Toothbrushing is fundamental to oral hygiene. Children differ in manual dexterity and their grip on toothbrushes. We videotaped toothbrushing sessions and observed the grip type, duration of brushing, and brushing technique used among 100 children aged 8-12 years. We then investigated the association between grip type and plaque removal, using plaque scores obtained at various time points. We f...
