TiF4 and NaF varnishes as anti-erosive agents on enamel and dentin erosion progression in vitro.
Objective This study assessed the effect of fluoride varnishes on the progression of tooth erosion in vitro. Forty-eight enamel and 60 root dentin samples were previously demineralized (0.1% citric acid, pH 2.5, 30 min), leading to a baseline and erosive wear of 12.9 and 11.4 µm, respectively. The s...
Relationship between acetaldehyde concentration in mouth air and tongue coating volume.
Objective Acetaldehyde is the first metabolite of ethanol and is produced in the epithelium by mucosal ALDH, while higher levels are derived from microbial oxidation of ethanol by oral microflora such as Candida species. However, it is uncertain whether acetaldehyde concentration in human breath is...
The interaction of polyacid-modified composite resins ('compomers') with aqueous fluoride solutions.
The aim of this study was to investigate how the release of fluoride from two compomers and a fluoridated composite resin was affected by exposure to KF solution. Two compomers (Dyract AP and Compoglass F) and one fluoridated composite (Wave) were prepared as discs (6 mm diameter and 2 mm thick), cu...
Effect of a propolis extract on Streptococcus mutans counts in vivo.
To evaluate the antibacterial action of an extract of geopropolis produced by the bee Melipona compressipes fasciculata on the concentration of Streptococcus mutans colonizing the oral cavity of young patients. Forty-one young volunteers performed 21 mouth rinses divided into three rinses per day fo...
Current panorama of temporomandibular disorders' field in Brazil.
We hope to discuss the importance of the recognition of this specialty and the inclusion of these subjects in undergraduate programs in Dentistry. The objective of this study is to perform a bibliometric survey of researches regarding Temporomandibular Disorders and Orofacial Pain conducted in the c...
Serum levels of inflammatory markers in type 2 diabetes patients with chronic periodontitis.
Diabetes has been associated with periodontitis, but the mechanisms through which periodontal diseases affect the metabolic control remain unclear. This study aimed to evaluate serum leveis of inflammatory markers, IL-8, IL-6 and monocyte chemoattractant protein 1 (MCP-1), in type 2 diabetic patient...
Human tooth germ stem cell response to calcium-silicate based endodontic cements.
The aim of this study was to compare the cytotoxic effects of endodontic cements on human tooth germ stem cells (hTGSCs). MTA Fillapex, a mineral trioxide aggregate (MTA)-based, salicylate resin containing root canal sealer, was compared with iRoot SP, a bioceramic sealer, and AH Plus Jet, an epoxy...
Multi-purpose materials in dentistry - is it possible to match maximum mechanical and biological properties/performance?
Comparison of manual, digital and lateral CBCT cephalometric analyses.
The aim of this study was to compare the reliability of three different methods of cephalometric analysis. Conventional pretreatment lateral cephalograms and cone beam computed tomography (CBCT) scans from 50 subjects from a radiological clinic were selected in order to test the three methods: manua...
CCL3 and CXCL12 production in vitro by dental pulp fibroblasts from permanent and deciduous teeth stimulated by Porphyromonas gingivalis LPS...
The aim of this study was to compare the production of the chemokines CCL3 and CXCL12 by cultured dental pulp fibroblasts from permanent (PDPF) and deciduous (DDPF) teeth under stimulation by Porphyromonas gingivalis LPS (PgLPS). Primary culture of fibroblasts from permanent (n=3) and deciduous (n=2...
