Push-out bond strength of MTA HP, a new high-plasticity calcium silicate-based cement

Braz. oral res. (Online); 30 (1), 2016
Abstract This study was designed to investigate the resistance to dislodgment provided by MTA HP, a new high-plasticity calcium silicate-based cement. Biodentine and White MTA Angelus were used as reference materials for comparison. Three discs 1 ± 0.1 mm thick were obtained from the middle third of the...

Volume of sealer in the apical region of teeth filled by different techniques: a micro-CT analysis

Braz. oral res. (Online); 30 (1), 2016
Abstract The volume of sealer in the apical 1 mm of teeth filled using different techniques was evaluated by micro-commuted tomography (micro-CT). Sixty-four maxillary central incisors were prepared using NiTi rotary instruments. Teeth were randomly distributed into four groups according to root canal se...

Dental flossing as a diagnostic method for proximal gingivitis: a validation study

Braz. oral res. (Online); 30 (1), 2016
ABSTRACT This study evaluated the clinical diagnosis of proximal gingivitis by comparing two methods: dental flossing and the gingival bleeding index (GBI). One hundred subjects (aged at least 18 years, with 15% of positive proximal sites for GBI, without proximal attachment loss) were randomized into fi...

Erosion and abrasion-inhibiting in situ effect of the Euclea natalensis plant of African regions

Braz. oral res. (Online); 30 (1), 2016
Abstract This study evaluated the effect of Euclea natalensis gel on the reduction of erosive wear with or without abrasion, in enamel and dentin. During two five-day experimental crossover phases, volunteers (n = 10) wore palatal devices containing human enamel and dentin blocks (E = 8 and D = 8). The g...

Enamel and dentine demineralization by a combination of starch and sucrose in a biofilm - caries model

Braz. oral res. (Online); 30 (1), 2016
Abstract Sucrose is the most cariogenic dietary carbohydrate and starch is considered non-cariogenic for enamel and moderately cariogenic for dentine. However, the cariogenicity of the combination of starch and sucrose remains unclear. The aim of this study was to evaluate the effect of this combination ...

Six-month color change and water sorption of 9 new-generation flowable composites in 6 staining solutions

Braz. oral res. (Online); 30 (1), 2016
Abstract Color match and water sorption are two factors that affect restorative materials. Discoloration is essential in the lifespan of restorations. The aim of this study was to evaluate color change and water sorption of nine flowable composites at multiple time points over 6 months. 60 samples of eac...

Impact of mandibular conventional denture and overdenture on quality of life and masticatory efficiency

Braz. oral res. (Online); 30 (1), 2016
Abstract The aim of this non-randomized controlled clinical trial was to evaluate the oral health-related quality of life and masticatory efficiency of patients rehabilitated with mandibular two-implant overdentures with immediate loading or conventional dentures. Fifty completely edentulous patients wea...

Patients with dental calculus have increased saliva and gingival crevicular fluid fetuin-A levels but no association with fetuin-A polymorphisms

Braz. oral res. (Online); 30 (1), 2016
ABSTRACT: Fetuin-A is a potent inhibitor of calcium-phosphate precipitation and of the calcification process, therefore it can also be related with dental calculus. Thus, we aimed to investigate a possible relationship between fetuin-A gene polymorphism and the presence of dental calculus. A possible rel...

Impact of a dental care program on the quality of life of children with and without caries

Braz. oral res. (Online); 30 (1), 2016
Abstract: The aim of the present study was to evaluate the long-term effects of the caries treatment provided by a dental care program on changes in schoolchildren's OHRQoL. A one-year follow-up was conducted with a sample of 372 children aged 8 to 10 years which were clinically examined and divided into...
