Treatments during pH cycling (28 days; 6 × 120 min demineralization/day) were brushing 2×/day with 0 ppm F − [NaF 0 ], 500 ppm F − [NaF 500...

... formed on dentin in situ and a subsequent erosive challenge. Methods: The pellicle was formed on bovine dentin specimens for 3 min or 2 h in 3 subjects. After subjects rinsed with sterile water (negative control), 1% tannic acid, 1% hop extract, or tin/fluoride solution containing 800 ppm tin and 500 ppm...

...Anton Schestakow; Christina Bauer; Matthias Hannig While the ultrastructure of the enamel pellicle and its erosion protective properties are well studied, the dentin pellicle is still neglected in dental research. Therefore, the ultrastructure and erosion protective properties of a pellicle formed...

... their age estimated (∼10–100 years old) using established dental forensic methods. Enamel and root dentin slabs were prepared, embedded in acrylic blocks, flattened, and polished. The specimens were randomly assigned to one of three treatments ( n = 93): Sn+F (800 ppm Sn as SnCl 2 and 250 ppm F as NaF, pH...

... on sound dentin as well as on artificial dentin caries-like lesions. Methods: Bovine dentin specimens ( n = 240) with two different surfaces each (sound [ST] and artificial caries lesion [DT]) were prepared and randomly allocated to twelve groups. Weekly interventions during pH-cycling (28 days, 6 × 120...

Preisser; Rujin Wang; Andrea Ferreira Zandona The purpose of this study was to determine if the degree of fluorescence detected by fluorescence-aided caries excavation (FACE) correlates with dentin bacterial microbiome...

... trimetaphosphate (TMP) against dentin erosion and abrasion. Specimens of coronal dentin were divided into: placebo, 2.5% NaF, 5% NaF, 2.5% NaF + 5% TMP, and 5% NaF + 5% TMP groups ( n = 24/group). After single application of the varnishes, the samples were immersed in citric acid (0.05 mol/L, pH = 3.2, 5 min...

... spectroscopy (EDX), and micro-computed tomography (micro-CT). The qBSE-SEM images revealed that the silver particles could penetrate through the pellicle complex, along with the rod sheaths into the demineralized enamel rods and the dentinal tubules, and form silver-enriched barriers surrounding the carious...

...Lenita Marangoni-Lopes; Gabriela Rovai-Pavan; Carolina Steiner-Oliveira; Marinês Nobre-dos-Santos Objective: We aimed to evaluate whether radiotherapy causes changes in the mineral composition, hardness, and morphology of enamel and dentin of primary teeth. Materials and Methods: Thirty specimens...

... a high concentration of sugars, which can contribute to root caries development. To test this hypothesis, an experimental biofilm/caries model was used. Dentin slabs were used to grow biofilms of Streptococcus mutans UA159. Slabs/biofilms were exposed 3× per day to bovine milk with different fat content...

...Jun Xu; Congcong Miao; Zhenchuan Tian; Jinlu Li; Chunmei Zhang; Dongmei Yang Objective: Matrix metalloproteinases (MMPs) exist in human saliva and dentin and play an important role in the degradation of organic matrix in teeth. Chemically modified tetracycline-3 (CMT-3) is an inhibitor of MMPs. CMT...

Wierichs; Sabrina Stausberg; Julian Lausch; Hendrik Meyer-Lueckel; Marcella Esteves-Oliveira The aim of this study was to compare the caries-preventive effect of different fluoride varnishes on sound dentin as well as on artificial dentin caries-like lesions. Bovine dentin specimens ( n...

... dentin (RD). CD and RD were pulverized to powder, and proteins were extracted with 1% phosphoric acid. The extracted proteins and the demineralized powder were separately incubated in the following solutions: 4-aminophenylmercuric acetate (control) or a buffer solution at different pHs (2.5, 4.5, 5.0...

A total of 90 bovine enamel and 108 root dentin samples were treated as follows: control (no treatment), solution containing TiF 4 /NaF (500 ppm F - , pH 4.4), NaF varnish (24,500 ppm F - , pH 5.0), TiF 4 varnish (24,500 ppm F - , pH 1.0), TiF 4...

... within the microbiota - from the dynamic stability stage to the aciduric stage via the acidogenic stage [Takahashi and Nyvad, 2008]. Dentin and root caries can also be partly explained by this hypothesis; however, the fact that these tissues contain a considerable amount of organic material suggests...
