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 protected and a freely exposed area in the same specimen. Brushing was performed with either a: sonic (Sonicare PowerUp, Philips GmbH, Hamburg, Germany), b: oscillating-rotating (Oral B Vitality Precisions Clean, Procter & Gamble, Schwalbach am Taunus, Germany) or two different manual toothbrushes c: flat trim brush head toothbrush (Dr...

Dental problems among athletes have been cautioned due to negative impacts not only on their oral health but also on athletic performance. Acquirement of appropriate oral health behavior mainly composed of toothbrushing in childhood can be one of the most important strategies for advancing children's athletic possibilities. Although habits of screen viewing, including game playing, and TV viewing have direct impacts on children's health and behavioral development, little is known about the association between these habits and toothbrushing frequency...

CONTEXT: Mouthrinses are used, by many of our patients, as a complement to daily dental hygiene routine. The use of a toothbrush and an interproximal cleaning method may not be enough to control dental plaque. Essential oils and delmopinol mouth rinses are effective for the prevention of dental caries and gingivitis. To study the effect of an essential oil and a delmopinol mouth rinse on dental plaque bacteria, an in vitro study was developed. AIMS: The objective of this study was to determine the antibacterial activity of an essential oil and a delmopinol mouth rinse on Streptococcus mutans, Lactobacilli, and aerobic and anaerobic dental plaque nonspecific bacteria...

BACKGROUND: Nosocomial pneumonia has correlated to dental plaque and to oropharynx colonization in patients receiving mechanical ventilation. The interruption of this process, by preventing colonization of pathogenic bacteria, represents a potential procedure for the prevention of ventilator-associated pneumonia (VAP). METHODS: The study design was a prospective, randomized trial to verify if oral hygiene through toothbrushing plus chlorhexidine in gel at 0.12% reduces the incidence of ventilatior-associated pneumonia, the duration of mechanical ventilation, the length of hospital stay and the mortality rate in ICUs, when compared to oral hygiene only with chlorhexidine, solution of 0...

INTRODUCTION: It has been well documented that the absence of family support influences the general and oral health of the children. Factors that lead to the development of disease at a given point in time are likely to have their roots in a complex chain of environmental events that may have begun years before. A number of studies have examined the relationship between dental caries and material deprivation and found a positive association between them. Though orphans contribute to 2% of world's population, literature regarding their oral health status is very scarce...

Foreign bodies are a common problem in the daily endoscopic practice. Nevertheless, long objects as toothbrushes, sometimes pose a special problem when trying to remove them from the stomach, due to the difficulty of passing through the hiatus. Endoscopic retrieval of toothbrushes has seldom be reported.
