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...

Birth weight classification in gestational diabetes: is there an ideal chart?

Clin. biomed. res; 36 (4), 2016
Introduction: Gestational diabetes mellitus (GDM) is associated to increased rates of large for gestational age (LGA) newborns and macrosomia. Several charts are used to classify birth weight. Is there an ideal chart to classify newborns of GDM mothers? Methods: We evaluated adequacy of birth weight of 3...

Marginal and internal fit of zirconia copings obtained using different digital scanning methods

Braz. oral res. (Online); 30 (1), 2016
Abstract The objective of this study was to evaluate the marginal and internal fit of zirconia copings obtained with different digital scanning methods. A human mandibular first molar was set in a typodont with its adjacent and antagonist teeth and prepared for an all-ceramic crown. Digital impressions w...

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...

Location and classification of Canalis sinuosus for cone beam computed tomography: avoiding misdiagnosis

Braz. oral res. (Online); 30 (1), 2016
Abstract The aim of this study was to assess the presence, location and, multiplanar distance of the canalis sinuosus (CS) between the incisive foramen and the anterior maxillary alveolar ridge using cone beam computed tomography (CBCT). Therefore, 500 CBCT maxillary images obtained from male and female ...

Effects of alveolar bone displacement with segmental osteotomy: micro-CT and histomorphometric analysis in rats

Braz. oral res. (Online); 30 (1), 2016
Abstract The purpose of this study was to evaluate the effects of segmental osteotomy on the blood vessels and osteoclasts in rats using micro-computed tomography (micro-CT) and histomorphometric analysis. After segmental osteotomy was performed around the maxillary first molars of 36 male Sprague-Dawley...

Tumor-associated macrophages (TAMs): clinical-pathological parameters in squamous cell carcinomas of the lower lip

Braz. oral res. (Online); 30 (1), 2016
Abstract The objective of this study was to analyze the presence of tumor-associated macrophage (TAM) subpopulations M1 and M2 in squamous cell carcinoma of the lower lip (SCCLL) by immunohistochemitry, and to evaluate the possible role of these subtypes in the development of regional lymph node metastas...

Longitudinal study on clinical and microbial analysis of periodontal status in pregnancy

Braz. oral res. (Online); 30 (1), 2016
Abstract This study was aimed to provide a longitudinal overview of the subgingival bacterial microbiome using fluorescence in situ hybridization (FISH) technique, in women in the second trimester of pregnancy (between 14 and 24 weeks), and 48 h and 8 weeks postpartum. Of 31 women evaluated during pregna...

Agreement between clinical and histopathologic diagnoses and completeness of oral biopsy forms

Braz. oral res. (Online); 30 (1), 2016
Abstract The present study aimed to assess the rate of agreement between clinical and histopathological diagnoses and to report the frequency of completed forms for specimens that were subjected to histopathological examination and retrospectively examined. Data from 8,168 specimens submitted to histopat...
