The aim of this study was to assess in vitro the surface roughness (Ra) of human enamel exposed or not exposed to the action of a bleaching agent containing 10% carbamide peroxide (CP) after brushing with different dentifrices. Ninety-six human enamel specimens were divided into 2 groups: GI--exposed to the action of 10% CP; GII--not exposed. These were subdivided into 4 brushing subgroups: (CE...

MOTIVATION Visualizing search histories and supplying the user with interaction methods such as zooming, brushing and linking, annotation and tagging, has attracted increasing attention in scientific literature (Liu, Hong, & Pedersen, 2010), (Pedersen, Gyllstrom, Gu, & Hong, 2010), (Cernea, Truderung, Kerren, & Ebert, 2013), and (Yu & Ingalls, 2011). The overall assumption is that the user’s in...

In graph cleaning problems, brushes clean a graph by traversing it subject to certain rules. We consider the process where at each time step, a vertex that has at least as many brushes as incident, contaminated edges, sends brushes down these edges to clean them. Various problems arise, such as determining the minimum number of brushes (called the brush number) that are required to clean the en...

Purpose: This study aimed to assess the efficacy of palatal brushing in the treatment of denture stomatitis. Materials and Methods: After screening 143 individuals with a potential diagnosis of denture stomatitis, 48 patients (mean age: 66.0 ± 11.2 years) were enrolled in a two-center phase 1 clinical trial with a one-group pretest/posttest design. The intervention of interest was manual palata...

We designed and applied novel interactive visualisation to investigate how social networks – derived from smartphone logs – are embedded in time and space. Social networks were identified through direct calls between participants and calls to mutual contacts of participants. Direct contact between participants was sparse and deriving networks through mutual contacts helped enrich the social net...
