Antimicrobial action of calcium hydroxide-based endodontic sealers after setting, against E. faecalis biofilm

Braz. oral res. (Online); 30 (1), 2016
Abstract Enterococcus faecalis are gram positive bacteria that can mostly resist endodontic therapy, inducing persistent infection in the root canal system. Endodontic sealers with antimicrobial activity may help eliminate residual microorganisms that survive endodontic treatment. The present study aimed...

Response of a co-culture model of epithelial cells and gingival fibroblasts to zoledronic acid

Braz. oral res. (Online); 30 (1), 2016
Abstract Osteonecrosis of the jaw is an adverse effect of bisphosphonates. While the etiopathogenesis of this condition has been investigated, the interactions and effects of bisphosphonates on oral mucosa cells remain unclear. It is hypothesized that cell culture models, such as co-culture or three-dime...

The effect of smoking on myeloid-related protein-8 and myeloid-related protein-14

Braz. oral res. (Online); 30 (1), 2016
Abstract The aim of this study was to determine the myeloid-related protein-8 and myeloid-related protein-14 levels in the gingival crevicular fluid of smoker patients with generalized aggressive periodontitis (SAgP), smoker patients with chronic periodontitis (SCP), smoker patients with gingivitis (SG-s...

Non-linear indices of heart rate variability during endodontic treatment

Braz. oral res. (Online); 30 (1), 2016
Abstract Dental treatment promotes psychosomatic change that can influence the procedure and compromise the general well-being of the patient. In this context, it highlights the importance of evaluating the function of the autonomic nervous system in individuals undergoing endodontic treatment. Thus, thi...

Clinical effect of photodynamic therapy on primary carious dentin after partial caries removal

Braz. oral res. (Online); 30 (1), 2016
Abstract This study was conducted to assess the clinical effect of photodynamic therapy (PDT) in the decontamination of the deep dentin of deciduous molars submitted to partial removal of carious tissue. After cavity preparation, dentin samples were taken from the pulp wall of nineteen deciduous molars b...

Drugs or disease: evaluating salivary function in RA patients

Braz. oral res. (Online); 30 (1), 2016
Abstract Oral complications of RA may include temporomandibular joint disorders, mucosa alterations and symptoms of dry mouth. The aim of this study was to evaluate the salivary gland function of subjects with rheumatoid arthritis (RA) comparing it to healthy controls. Subjects with other systemic condit...

Cytotoxic effects of new MTA-based cement formulations on fibroblast-like MDPL-20 cells

Braz. oral res. (Online); 30 (1), 2016
Abstract The present study aimed at evaluating the cytotoxic effects of a novel cement called CER on periodontal fibroblast-like cells of mice (MDPL-20), in comparison with different formulations of Mineral Trioxide Aggregate (MTA), by means of the cell viability test (MTT) and cell morphology analysis. ...

Effect of different salivary exposure times on the rehardening of acid-softened enamel

Braz. oral res. (Online); 30 (1), 2016
Abstract This in situ study assessed the effect of different times of salivary exposure on the rehardening of acid-softened enamel. Bovine enamel blocks were subjected in vitro to a short-term acidic exposure by immersion in 0.05 M (pH 2.5) citric acid for 30 s, resulting in surface softening. Then, 40 s...

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,...
