... on plaque fluid and salivary fluid fluoride has not been examined. The purpose of this study was to investigate the effect of SLS on these parameters and to examine the effect of this ion on total (or whole) plaque fluoride, an important source of plaque fluid fluoride after a sufficient interval following...

... for dental caries has been associated with reduced ADS activity of the bacteria in oral biofilms. Arginolytic bacterial strains from dental plaque samples of caries-free and caries-active adults were isolated and characterized to investigate the basis for differences in plaque ADS activity between...

...G.L. Vogel; L.M.A. Tenuta; G.E. Schumacher; L.C. Chow The purpose of this study is to determine whether a calcium (Ca) prerinse used before a 228 µg/g (ppm) fluoride (F) rinse would induce the formation of ‘calcium fluoride-like' (CaF 2 -like) deposits in human dental plaque. Sixty minutes after...

... to be much more diverse and individually differing. The aim of this study, therefore, was to analyze the bacterial composition of carious dentin and the plaque of caries-free patients by using a custom-made, real-time quantitative polymerase chain reaction assay (RQ-PCR). Methods: The study included 26...

...J. Neilands; L.G. Petersson; D. Beighton; G. Svensäter In this study we investigated the effect of fluoride on plaque acid tolerance. The test group consumed 200 ml of milk supplemented with 5 mg F/l as NaF once a day, the milk control group drank 200 ml of unsupplemented milk, and the no-milk...

... supragingival plaque and whole saliva samples from 93 subjects, who were in three different groups: caries-free (n = 31), caries-active (n = 30), and caries-experienced (n = 32). ADS activity was measured by quantification of the ammonia generated from the incubation of plaque and saliva samples in a mixture...

...M.P.T. Otten; H.J. Busscher; H.C. van der Mei; F. Abbas; C.G. van Hoogmoed The aim of this study was to determine the contribution of plaque and saliva towards the prolonged activity, also called substantivity, of three antimicrobial mouthrinses (Listerine®, Meridol®, Crest Pro Health®), used...

...K.-L.C. Hsu; R.C. Osgood; G.R. Cutter; N.K. Childers The aim of this study was to determine the reproducibility of individual versus pooled plaque sampling of permanent first molars (PFM) to quantitate Streptococcus mutans (SM)/total streptococci (TS). Ten individual and pooled plaque samples were...

...G.L. Vogel; L.M.A. Tenuta; G.E. Schumacher; L.C. Chow Plaque ‘calcium-fluoride-like’ (CaF 2 -like) and fluoride deposits held by biological/bacterial calcium fluoride (Ca-F) bonds appear to be the source of cariostatic concentrations of fluoride in plaque fluid. The aim of this study...

... in situ, using a test plaque of a strain of Streptococcus mutans which presents high MFPase activity at pH 5.0. The test plaque was exposed to non-F or MFP (1,450 µg F/g) dentifrices and the fluid phase of the plaque was analyzed after 15, 30, 45 and 75 min. MFP concentration in the plaque fluid decreased...

...J.F. Tahmassebi; M.S. Duggal This study investigated differences in the response of dental plaque pH after a carbohydrate challenge in children and adults. A 10% (w/v) sucrose solution and a blackcurrant drink containing 7% carbohydrate (w/v) were assessed for their ability to depress plaque pH...

.... In this study fluoride concentrations in plaque on 1-year old resin-modified GIC, compomer and resin composite restorations were compared intraindividually and related to the occurrence of caries-associated bacteria. Plaque from class III restorations of the three restorative materials and from a proximal...

... with and without added 0.103% citrate by measuring its ability to depress plaque pH in 20 adult subjects using the plaque-harvesting technique. Solutions of 10% sucrose and 10% sorbitol were used as positive and negative controls, respectively. The results showed that the blackcurrant drink with added citrate had...

...A.F. Hall; S.L. Creanor; R. Strang; R. Foye Plaque pH was measured using a glass combination pH microelectrode of plaque deposits lining the trough of an intra-oral appliance which contained single sections of human teeth with artificial enamel lesions. Plaque exposure to a 10% sucrose solution...

...J. Tahmassebi; M.S. Duggal; M.E.J. Curzon The effects of a calcium carbonate-based toothpaste with added 0.3% triclosan on the pH of human dental plaque after a cariogenic challenge with 10% sucrose solution was investigated against a calcium carbonate-based toothpaste without triclosan...

...H.C. Margolis; Y.P. Zhang; J. van Houte; E.C. Moreno Pooled plaque samples were obtained from (1) coronal surfaces of two groups of caries-free (CF) subjects (2) coronal ‘white-spot’ surface areas of a group of caries-positive (CP) subjects, and (3) exposed, sound root surfaces of root caries-free...

...M.A. Pollard; M.S. Duggal; M.E.J. Curzon The effect of 0.1, 0.2 and 0.4% citrate in 10% sucrose solutions on the plaque pH in vivo was tested in 20 volunteers using the plaque harvesting technique. Results showed that the pH response for the three test solutions with citrate was significantly less...
