OBJECTIVES All gastric ulcers discovered at endoscopy are potentially malignant. Concurrent use of both histological biopsy and cytological brushing has been advocated as a means of increasing the diagnostic yield for neoplasia at the time of initial endoscopy. The purpose of this analysis was to determine the impact of these diagnostic strategies on the cost-effectiveness of detecting malignan...

AIM The aim of this systematic review was to produce the best available evidence and pool appropriate data to evaluate the effect of tooth brushing on the initiation and progression of non-inflammatory gingival recession. MATERIAL AND METHODS A protocol was developed a priori for the question: "Do factors associated with tooth brushing predict the development and progression of non-inflammato...

The purpose of the study was the evaluation of the dental plaque and the influence of determined hygienic factors on gingival recession occurrence in 455 students of The Medical University of Bialystok. All the subjects were examined in artificial light, with the use of the probe, mirror, and parodontometer. The distribution of stained dental deposits were estimated with the use of the plaque i...

The aim of this study was to evaluate the effect of brushing with a Colgate 360º or Oral B Indicator 35 toothbrush on the shear bond strength of orthodontic brackets bonded to extracted human teeth. The bristle wear and bristle tip morphology were also examined after simulated tooth-brushing. Orthodontic brackets (Roth-P/1st and 2nd premolar S/D- Slot 0.18") were bonded (Transbond XT) to the sm...

BACKGROUND Clinical validation of laboratory toothbrushing tests has important advantages. It was, therefore, the aim to demonstrate correlation of tooth cleaning efficiency of a new robot brushing simulation technique with clinical plaque removal. METHODS Clinical programme: 27 subjects received dental cleaning prior to 3-day-plaque-regrowth-interval. Plaque was stained, photographically doc...

In this paper we present angular brushing for parallel coordinates (PC) as a new approach to highlighting rational data-properties, i.e., features which – in a non-separable way – depend on two data dimensions. We also demonstrate smooth brushing as an intuitive tool for specifying nonbinary degree-of-interest functions (for focus+context visualization). We also briefly describe our implementat...

The complex structure of longitudinal data with associated discrete covariates requires developing visual methods for a better understanding of underlying structures. In this paper, a simple and flexible method, linked brushing, was studied for such datasets to detect the mean structure. Methods were applied to a random dataset from The Panel Study of Income Dynamics (PSID), which was first use...

As the complexity and amount of real world data continuously grows, modern visualization systems are changing. Traditional information visualization techniques are often not sufficient to allow an in-depth visual data exploration process. Multiple view systems combined with linking & brushing are only one building block of a successful InfoVis system. In this paper we propose the incorporation ...
