OBJECTIVES The aim of this study was to evaluate the influence of two adhesive systems and the post space region on the degree of conversion of dual resin cement and its bond strength to root dentin. MATERIAL AND METHODS One three-step etch-and-rinse (All-bond 2, Bisco) and another one-step self-etch (Xeno III, Dentsply) adhesive systems were applied on 20 (n=10) crownless bovine incisors, at...

Background Intraradicular procedures remove radicular dentin and jeopardizing longevity of a tooth. Traditional in vitro methods used to determine the remaining dentin thickness (RDT) have limitations. Aim The aim is to evaluate, using cone-beam computed tomography (CBCT), RDT following rotary instrumentation and post space preparation in buccal and palatal roots of maxillary first premolars....

In this paper, a color-based segmentation scheme applied to dermatoscopic scar images is proposed. The image is first preprocessed via a partial differential equations (PDE)-based filter which combines in the RGB color space coherent anisotropic diffusion and shock filters. Then the scar image is segmented using a segmentation algorithm based on color distributions. A post-processing algorithm ...

Accompanied by increased stiffness and indicated radiographically by progressive loss of joint space and subchondral cystic changes, chondrolysis has been documented in the hip, knee, ankle, and most notably the shoulder. As the articular surfaces degrade, a concurrent inflammatory response manifests as arthrofibrosis, as early as six months post-operatively. This leads to progressive, and refr...

Abstract This research investigates the potential of eye tracking as an interface to parameter search in visual design. We outline our experimental framework where a user’s gaze acts as guiding feedback mechanism in an exploration of the state space of paramet...

Automatic extraction of features is a promising strategy to cope with the large amount of data produced by time-dependent CFD (computational fluid dynamics) simulations. Computation time for this type of simulations is typically in the order of days, which justifies the time spent on post-processing the data by extracting features in a batch run. Automatic feature extraction can achieve data re...

We propose a method for drawing gaze to a given target in videos, by modulating the value of pixels based on the saliency map. The change of pixel values is described by enhancement maps, which are weighted combination of center-surround difference maps of intensity channel and two color opponency channels. Enhancement maps are applied to each video frame in the HSI color space to increase sali...

introduction: lipomas of the larynx are very rare benign lesions; macroscopically, they resemble retention cysts, so their diagnosis is usually made after surgery.   case report: a rare case of pediatric paraglottic space lipoma in an 11-year-old boy is explained. the mass was mobile, soft, without fluctuation or pulsation. ct scan revealed a 5.7 cm cervical fat density with regional lymphadeno...
