The purpose of this study was to compare the difference between the rolling toothbrushing motion a newly designed brushing machine and three subjects who were skilled in the rolling toothbrushing technique. The evaluation of the distortion curves of the rolling toothbrushing motion recorded by a tri-axial strain gauge attached to the shank of the toothbrush indicate the newly designed brushing ...

We evaluated the effect of toothbrush/dentifrice brushing on weight variation and surface properties different denture bases. Four base materials (conventional heat cure, high impact, CAD/CAM, polyamide resins) were subjected to toothbrushing abrasion (50,000 strokes). The value, roughness, topography each group determined before after toothbrushing. hardness was measured by Vickers test. Data ...

Dental implants have increased the use of titanium and titanium alloys in prosthetic applications. Whitening toothpastes with peroxides are available for patients with high aesthetic requirements, but the effect of whitening toothpastes on titanium surfaces is not yet known, although titanium is prone to fluoride ion attack. Thus, the aim of the present study was to compare Ti-5Ta alloy to cp T...

BACKGROUND Ventilator-associated pneumonia is associated with increased morbidity and mortality. OBJECTIVE To examine the effects of mechanical (toothbrushing), pharmacological (topical oral chlorhexidine), and combination (toothbrushing plus chlorhexidine) oral care on the development of ventilator-associated pneumonia in critically ill patients receiving mechanical ventilation. METHODS Cr...

OBJECTIVE To examine the association between toothbrushing habits of 8-9 year-olds and maternal behaviours and attitudes towards oral health in a sample of Japanese population. METHODS Cross-sectional data on mothers' behaviours and attitudes towards oral health and children's toothbrushing habits were collected from 378 mother-child pairs by self-administered questionnaires. Logistic regress...

The concentration of testosterone in whole saliva is significantly increased (by 9%) after toothbrushing. In ultrafiltrates of saliva collected at the same time as the whole saliva, testosterone concentrations after toothbrushing were unchanged. In 88% of the 162 whole-saliva specimens, but not in the ultrafiltrates, we also measured higher hemoglobin concentrations after toothbrushing. We conc...

BACKGROUND/AIMS The use of cold water during toothbrushing can cause dentine sensitivity and, to avoid this painful stimulus, some patients used to rinse their mouths with warm water when brushing. Thus, the objective of this study was to determine the effect of water temperature on the dental root surface during toothbrushing. MATERIALS AND METHODS Fragments of bovine dental roots were submi...

The aim of this study was to determine the influence of mouthrinses on the surface roughness of a nanofilled composite resin after toothbrushing. One hundred nanofilled composite resin specimens were prepared and randomly distributed into two groups-brushed and non-brushed-and then assigned to five subgroups, according to the mouthrinse solutions (n = 10): Colgate Plax Fresh Mint, Oral B, Cepac...
