AIM To assess the potential of acute alcohol consumption to dissolve tooth surfaces and to evaluate the difference in the dissolution potential of whisky, beer and wine. METHODS The study sample comprised 36 healthy male volunteers with mean age of 26.27 (SD-1.96) years (range 25-30 years). The study design involved randomly allocating the 36 individuals into three groups of alcohol consumpti...

OBJECTIVE This study aimed to compare the effects 0.5% and 1% sodium, amine and stannous fluoride at different pH on enamel erosion in vitro. METHODS Bovine enamel samples were submitted to a cyclic de- and remineralisation for 3 days. Each day, the samples were exposed for 120 min to pooled human saliva and subsequently treated with one of the fluoride solutions for 3 min: amine fluoride (Am...

In the present study, the growth of a single isolate of Candida albicans on saliva-, serum-coated or protein free (uncoated), thermocycled (4-70 degrees C for 1 min, respectively; 0, 1000 and 10 000 times) 15 commercial maxillofacial materials was investigated, by monitoring pH changes in growth media. The inhibitory effect of the tissue conditioners on fungal growth was analysed using three pa...

Results: Drug-Eudragit granules E3 prepared by mass extrusion method gave less than 10% of drug in simulated saliva fluid and almost complete release in simulated gastric fluid after 2 minutes. Therefore, it was used to prepare oro-dispersible tablets formulas. In vitro disintegration time of formula T2 was 45.5 ± 7.7 seconds showed a complete drug release of Prifinium Bromide in phosphate buff...

The development of sugarfree gum provided the possibility of a noncariogenic alternative to sugared gum. Chewing sugarfree gum results in a rise in plaque pH, in contrast to the pH fall observed with sugared gum. This is due to the stimulation of the flow of saliva, with the resulting increase in level of bicarbonate and thus alkalinity. At the same time the plaque microflora do not produce sig...

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 ...

Radiation caries have been reported to be correlated with radiotherapy-induced destruction of salivary function and changes in oral microbiota. There have been no published reports detailing patients who have remained radiation caries-free following radiotherapy for nasopharyngeal carcinoma. The aim of this study was to investigate the relationship between salivary function, oral microbiota and...

BACKGROUND The aim of this study was to investigate the corrosive behaviour of stainless steel archwires in a more clinically relevant way by bending and exposing to various pH. METHODS One hundred and twenty pieces of rectangular stainless steel wires (0.43 × 0.64 mm) were randomly assigned into four groups. In each group, there were 15 pieces of bent wires and 15 straight ones. Prior to mea...
