Analysis of Interleukin 17A in periapical abscess and granuloma lesions

Braz. oral res. (Online); 30 (1), 2016
Abstract Interleukin 17A (IL-17A) is a proinflammatory cytokine responsible for the initiation and propagation of inflammation. One of its actions is the recruitment of neutrophils to the site of infection. The aim of this study was to investigate whether there is association between IL-17A expression an...

Optimizing light-cured composite through variations in camphorquinone and butylhydroxytoluene concentrations

Braz. oral res. (Online); 30 (1), 2016
Abstract The use of a free-radical polymerization inhibitor, butylhydroxytoluene (BHT), and a common photo-initiator, camphorquinone (CQ), to reduce polymerization stress in dental composite was investigated in this study. Samples were prepared by mixing Bis-GMA, UDMA, and TEGDMA at a 1:1:1 ratio (wt%), ...

Tomographic evaluation of the temporomandibular joint in malocclusion subjects: condylar morphology and position

Braz. oral res. (Online); 30 (1), 2016
Abstract The aim of this study was to investigate condyle concentricity and morphology, and their association with Class I and II malocclusions (Angle). The sample consisted of 49 individuals of both genders, between 11 and 35 years old, divided into two groups, G1: 26 patients with Class I malocclusion,...

Training and calibration of interviewers for oral health literacy using the BREALD-30 in epidemiological studies

Braz. oral res. (Online); 30 (1), 2016
Abstract The objective of this study was to describe an interviewer training and calibration method to evaluate oral health literacy using the Brazilian Rapid Estimate of Adult Literacy in Dentistry (BREALD-30) in epidemiological studies. An experienced researcher (gold standard) conducted all training s...

Dissolution of a mineral trioxide aggregate sealer in endodontic solvents compared to conventional sealers

Braz. oral res. (Online); 30 (1), 2016
Abstract The aim of this study is to evaluate the solubility of a Mineral Trioxide Aggregate sealer (MTA-Fillapex) compared with five other sealers, calcium hydroxide (Sealapex), resin (Realseal), zinc oxide-eugenol (Tubli-Seal), and two epoxy resins (AH-26 and AH-Plus), in chloroform and eucalyptoil in ...

Immunohistochemical analysis of FoxP3+ regulatory T cells in lower lip squamous cell carcinomas

Braz. oral res. (Online); 30 (1), 2016
Abstract: The aim of this study was to determine the number of FoxP3+ regulatory T (Treg) cells in the microenvironment of lower lip squamous cell carcinomas (LLSCCs) and to correlate the findings with clinicopathological parameters (tumor size/extent, regional lymph node metastasis, clinical stage, and ...

Effective method for the detection of piroxicam in human plasma using HPLC

Braz. oral res. (Online); 30 (1), 2016
Abstract Non-steroidal anti-inflammatory drugs (NSAIDs) are widely used by the general population to alleviate inflammation and pain after oral surgeries. Piroxicam is among the most commonly used NSAIDs and excels in controlling pain, swelling, trismus and other common symptoms of inflammation. This stu...

Effect of the time-point of acid etching on the persistence of sealer residues after using different dental cleaning protocols

Braz. oral res. (Online); 30 (1), 2016
Abstract: Endodontic sealer residues remaining within the pulp chamber dentin after root canal obturation and cleaning with various solvents may compromise the appearance and the durability of dental restorations. Acid etching is routinely performed prior to application of dentine adhesive systems, but i...

Assessment of serum copper, iron and immune complexes in potentially malignant disorders and oral cancer

Braz. oral res. (Online); 30 (1), 2016
Abstract Potentially malignant disorders (PMDs) of oral cavity and oral cancer remain a cause of serious concern despite intensive research and development. Diet and immunity have been identified to play a crucial role as modifying factors in these diseases. Our study intended to explore this relationshi...
