..., and aciduric bacteria in saliva and plaque were also examined. Material and Methods: Twenty adolescents and young adults (15-21 years) with no caries (n = 10, D m + i MFS = 0) or ≥1 new manifest lesions/year (n = 10, D m MFS = 3.4 ± 1.8) participated. After plaque sampling, interproximal plaque pH was measured...

... the relationship between plaque pH and different caries variables in adolescents with varying caries prevalence. One hundred individuals, aged 14-15 years, were examined regarding different caries-related variables: (i) caries score (DS m , DS i , DS m + i , DT m ), (ii) salivary secretion rate and buffer capacity...

...E. Brambilla; M.G. Cagetti; A. Ionescu; G. Campus; P. Lingström The effect of Stevia extracts on in vitro Streptococcus mutans biofilm formation and in vivo plaque pH was evaluated in this paper. Three 10% solutions containing stevioside, rebaudioside A or sucrose were prepared. MTT assay was used...

... included examinations at baseline, after 7 days, after 30 days of gum use and 7 days after the end of gum use. Plaque pH was assessed using the strip method following a sucrose challenge. Area under the curve (AUC 5.7 and AUC 6.2 ) was recorded. Whole saliva was collected and the number of salivary MS (CFU...

...A. Carlén; H. Hassan; P. Lingström Aim: The aim of the study was to evaluate if pH indicator strips could be used for measurements of plaque pH acidogenicity in situ. Method: Interproximal plaque pH was measured before and up to 60 min after a 10% sucrose rinse in 30 healthy volunteers using pH...

...G. Campus; M.G. Cagetti; G. Sacco; G. Solinas; S. Mastroberardino; P. Lingström A randomized clinical trial was designed to evaluate the effect of daily high-dose xylitol chewing gum on plaque pH and salivary mutans streptococci (MS) in a sample of schoolchildren at high risk of caries. The study...

...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...

...K. Sjögren; P. Lingström; A.-B. Lundberg; D. Birkhed The aim was to study the salivary fluoride (F) concentration and plaque pH recovery on the chewing and the non-chewing side of the dentition during and after chewing 1 piece of chewing gum containing 0.25 mg F as NaF. Ten subjects refrained from...

...P. Arneberg; E. Giertsen; H. Emberland; B. Øgaard The aim of the present investigation was to study intra-oral variations in total plaque fluoride, and to examine whether such variations were related to plaque pH. Five orthodontic patients abstained from oral hygiene and daily fluoride rinsing...

... 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...

... brought about enamel demineralization, but the pH of the streptococcal plaque fell slowly, and the initiation of demineralization was delayed. Thus, delta Ip and plaque pH were – 0.3 ± 1.3 U and 6.1 ± 0.3, respectively, after 15 min. The delay was shown to be related to the need to induce the acidogenic...

... and an alumina-based toothpaste. A silica-based toothpaste served as a control. Twenty adult volunteers were included in this study. The results showed that the plaque pH drop and the area under the curve for both calcium carbonate-based toothpastes, with and without 0.3% triclosan, were significantly less...

Paired t tests indicated that sorbitol did not cause the plaque pH to fall as low as any of the test foods (p < 0.05) but there was no significant difference between sucrose and the test foods. Only the fruits produced less acid than sucrose. The breakfast cereals...

...Louis M. Steinberg; Folarin Odusola; Irwin D. Mandel Our earlier work demonstrated that the sweetener sucralose, C 12 H 19 CI 3 O 8 , mixed with water had no effect on intraoral plaque pH. The current study compared the effect on resting plaque pH of sucralose to sucrose when these sweeteners were...
