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...

Gastric and renal effects of COX-2 selective and non-selective NSAIDs in rats receiving low-dose aspirin therapy

Braz. oral res. (Online); 30 (1), 2016
Abstract The consumption of low-dose aspirin (LDA) to prevent cardiovascular disease continues to increase worldwide. Consequently, the number of chronic LDA users seeking dental procedures that require complementary acute anti-inflammatory medication has also grown. Considering the lack of literature ev...

Biocompatibility and biomineralization assessment of bioceramic-, epoxy-, and calcium hydroxide-based sealers

Braz. oral res. (Online); 30 (1), 2016
Abstract Obturation of the root canal system aims to fill empty spaces, promoting hermetic sealing and preventing bacterial activity in periapical tissues. This should provide optimal conditions for repair, stimulating the process of biomineralization. An endodontic sealer should be biocompatible once it...

Effect of irrigation technique for removal of triple antibiotic paste on bond strength of MTA to root dentin

Braz. oral res. (Online); 30 (1), 2016
Abstract This study evaluated the bond strength of mineral trioxide aggregate (MTA) to root canal dentin after the performance of various irrigation procedures to remove triple antibiotic paste (TAP). A total of 56 single-rooted human mandibular premolars were instrumented using a rotary system to size 4...

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...

Micro-CT evaluation of the radioprotective effect of resveratrol on the mandibular incisors of irradiated rats

Braz. oral res. (Online); 30 (1), 2016
Abstract The purpose of this study was to perform a microcomputed tomographic evaluation of the radioprotective effect of resveratrol on the volume of mandibular incisors of irradiated rats. A second aim was to make a quantitative assessment of the effect of x-ray exposure on these dental tissues. Twenty...

Effects of different desensitizing treatments on root dentin permeability

Braz. oral res. (Online); 30 (1), 2016
Abstract The objective of this study was to evaluate the effects of diode laser and a desensitizing dentifrice on dentin permeability. Fifty-two root dentin fragments were obtained (5 × 5mm) and treated with 24% EDTA gel. The samples were divided into 4 groups (n = 13): G1, control (no treatment); G2, d...

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. ...
