Comparison of two visual methods for detecting caries among obese and non-obese children.

Objective: The study aimed to compare two visual methods for detecting caries among obese and non-obese children in Salvador, Brazil.

Materials And Methods: A cross-sectional study was conducted from 2011-2012, which evaluated 180 paediatric patients, 6-14 years old, girls and boys, categorized into two groups: obese and non-obese (healthy weight), according to the body mass index. For the evaluation of dental caries, the decayed, missing or filled teeth index (DMFT/dmft) and International Caries Detection and Assessment System II (ICDAS II) visual criteria were used.

Dimensional error of three-dimensional images generated by different software.

The aim of this study was to evaluate the accuracy of three-dimensional (3D) reconstructions generated by different software, computed tomography (CT) scanners and slice thicknesses. Ten human dry mandibles were scanned by CT and cone beam CT (CBCT). Digital files were processed in different software systems and 3D reconstructions were performed.

Lipidomics in the study of lipid metabolism: Current perspectives in the omic sciences.

The advances in systems biology and in the development of new technological tools in analysis, as well as in the omic sciences, among which, metabolomics, and more specifically, lipidomics, have made it possible to investigate the structural and functional complexity of lipids in biological systems. Liquid chromatography and mass spectrometry are the analytical approaches most used in lipid research. Biomedical research, with the development of specific markers for lipids, together with new software development, have both enabled the early diagnosis of several illnesses, besides the evaluation of drug activity and treatment efficacy.

Association between childhood obesity and oral hygiene status.

Objective: The purpose of this study was to evaluate the oral hygiene status in pediatric obese patients.

Methods: A cross-sectional study was conducted from 2011 to 2012, which evaluated 180 Brazilian pediatric patients, 6-14 years old, girls and boys, recruited according to two Body Mass Index (BMI) categories: obese and non-obese (healthy weight). For the evaluation the oral hygiene status, the study used Oral Hygiene Index (OHI) and Gingival Bleeding Index (GBI).

Application of two segmentation protocols during the processing of virtual images in rapid prototyping: ex vivo study with human dry mandibles.

Objectives: The aim of this study was to evaluate the accuracy of virtual three-dimensional (3D) reconstructions of human dry mandibles, produced from two segmentation protocols ("outline only" and "all-boundary lines").

Materials And Methods: Twenty virtual three-dimensional (3D) images were built from computed tomography exam (CT) of 10 dry mandibles, in which linear measurements between anatomical landmarks were obtained and compared to an error probability of 5 %.

Results: The results showed no statistically significant difference among the dry mandibles and the virtual 3D reconstructions produced from segmentation protocols tested (p = 0,24).

The oral manifestations of celiac disease: information for the pediatric dentist.

Purpose: The purpose of this article was to present a literature review of oral manifestations reported by celiac disease patients.

Methods: A review of the published literature for oral manifestations present in celiac disease patients was conducted from the following databases: PubMed(®); MEDLINE; Web of Science; Science Direct; and Scielo.

Results: According to some literature studies, prevalence of enamel defects and recurrent aphthous stomatitis was observed in approximately 10% to 96% and 4% to 41% of 2- to 86-year-old celiac patients, respectively.

Evaluation of the quality of different endodontic obturation techniques by digital radiography.

Objectives: This study was aimed to evaluate different endodontic obturation techniques (Thermafil, lateral condensation, and Tagger's hybrid technique) regarding the homogeneity of the obturation radiopacity.

Materials And Methods: Seventy roots of human upper central incisors were filled using the Thermafil system, lateral condensation. and Tagger's hybrid technique.
