ABSTRACTThe most common dental and oral health problems are caries periodontal disease caused by plaque. Dental plaque is a soft deposit consisting of microorganisms found on matrix that formed adheres tightly to the tooth surface. Bacteria in will metabolize food waste, especially type can be fermented so it produce acid. The acid produced lower pH 4.5-5.0 wthin 1-3 minutes return normal at 7 ...

AIM Cheeses have been investigated for their potential cariogenicity in several studies and have been shown to produce little change in the resting pH in dental plaque and little or no demineralisation of enamel in most intra-oral cariogenicity studies. The aim of the present study was to investigate the cariogenicity of four processed cheese formulations. METHODS Enamel demineralisation was ...

BACKGROUND AND PURPOSE Women are at lower risk of stroke, and appear to benefit less from carotid endarterectomy (CEA) than men. We hypothesised that this is due to more benign carotid disease in women mediating a lower risk of recurrent cerebrovascular events. To test this, we investigated sex differences in the prevalence of MRI detectable plaque hemorrhage (MRI PH) as an index of plaque inst...

A single overlay plaque assay was designed and evaluated for infectious hematopoietic necrosis virus. Epithelioma papillosum carpio cells were grown in normal atmosphere with tris(hydroxymethyl)aminomethane- or HEPES (N-2-hydroxyethylpiperazine-N'-2-ethanesulfonic acid)-buffered media. Plaques were larger and formed more quickly on 1- to 3-day-old cell monolayers than on older monolayers. Cell ...

Pre-softened, gauze-covered bovine enamel blocks were worn in the buccal sulcus of five subjects for seven days. Artificial plaque enmeshed in the gauze was treated four times per day for four days with an enzyme-dependent mineralizing solution, resulting in 20-, 10-, and 200-fold increases in Ca, P, and F, respectively. Enamel beneath this mineral-enriched plaque recovered 37% of the hardness ...

BACKGROUND AND PURPOSE Plaque hemorrhage (PH) may lead to accelerated progression of atherosclerotic disease. The presence of local PH in the carotid plaque predicts future cardiovascular events in any vascular territory. We investigated the prevalence of local PH and the predictive value of PH for the occurrence of cardiovascular events in men and women separately. METHODS Atherosclerotic pl...

Modern techniques in dental research continue to assist in the study of the mode of (anticaries) action of topical fluorides. The Plaque Glycolysis and Regrowth Model (PGRM) facilitates the standardized assessments of antimicrobial effects on plaque following use of test formulations in vivo without complications arising from coincident mineral reactivity. In vivo plaque glycolysis testing demo...
