Diagnóstico e tratamento precoce da Classe III: relato de um caso clínico

In malocclusion studies, may happen not only dental discrepancies but even skeletal discrepancies. In Class III malocclusion can be observed underdeveloped maxilla, mandible protraction or both of them, and, in most of the times associated with a narrow maxilla that causes anterior or posterior crossbites, in one side or in two sides. The aim of this case report is to evaluate the facial profile and occlusal effects of interceptive orthodontics therapy. The treatment with upper arch expansion and maxilla protraction was done in an early age to be effective in the circummaxillary sutural system and to make the orthopedic effect easier. The facial mask used is positioned on two facial points and allows an anterior maxillary replacement. Patients’ compliance is important to reach treatment success, this because using the mask still in this growth and development phase is essential to make the facial and occlusal effects happen. It is important to mention that patients with Angle Class III malocclusion need to be followed till the end of their growth.

A geografia agrária brasileira: dinâmica, variada e complexa

This paper is a contribution to the debate on the methodological issues surrounding the Land Geography, demonstrating why the Brazilian Agrarian Geography is dynamic, varied and complex. It was chosen as the theme of Research Groups in Geography Agrarian present in Directory Groups CNPq and they held on a characterization considering: home institution, location, year of training, Group name, words and lines of research. The survey allowed the treatment of 70 groups in 2009 had the agrarian geography, agriculture, rural development, rural, rural areas, organization of space and rural development as guiding their research and performances. The analysis of the research lines identifi ed groups concerned with economic, political, ecological, demographic and cultural, and also found concerns with farmers, with their production and the functioning of the agricultural system, being thus, the set of raised lines one can say that there is signifi cant diversity in themes, which reinforces the hypothesis of dynamism, variety and complexity of studies on agriculture today.

The present article gets organized around two main axles. The first one briefly presents a discussion of aspects related to the study of epistolary documents as research source and discusses some issues of the correspondence exchanged between João Guimarães Rosa and his German translator Curt Meyer-Clason. In the sequence, elements are presented that, on basis of an analysis of published and unpublished letters, lead one to the consideration of work points and author’s poiësis aspects not yet openly considered by the specialized criticism on him.

Estudo anatomico da posição do forame mandibular e da língula em mandíbulas secas

Purpose: The authors tried to verify the anatomic location of the mandibular foramen and língula in dry jaws regarding the anterior and posterior border of the mandible and the incisure, alveolar border and mandibular base, in order to correlate the data with the sagittal split ramus osteotomy. Methods: There were evaluated 44 mandibles (88 sides) from the Morphology Department of the Araraquara Dental School of the São Paulo University (UNESP). The distances measured were previously deter - mined according to the figures presented in this article and were done by the use of a sliding caliper (Brow & Sharpe Digit-Cal Plus), with the mandibles positioned over a Erickson table, and the distan - ces were always measured in millimeters. Results: The pre-determined points and distances founded were X=17,67; Y=14,35; W=20,96 and Z=21,89 for the mandibular foramen, and the relationship between this anatomical structure and the língula shows that the mandibular foramen is in average 5,82 mm below the língula. Conclusions: The authors conclude that the mandibular foramen is lightly posterior in comparison with the ramus mandibular center and that the língula is a very important anatomic landmark for the ramus surgeries as well the knowledge of the distance between it and the mandibular foramen entrance.

Genetic divergence among maize hybrids by morphological descriptors

Two experiments with 25 maize commercial hybrids were carried out in a direct sowing system in Southern Brazil in the harvests of 2009/2010 and 2010/2011. Quantitative descriptors were used with the objective of determining the genetic divergence and the relative contributions of traits among hybrids for extraction of inbred lines. This study was carried out in Oxisol soil using a randomized block design with four replicates. Data were subjected to combined analysis of variance, and based on the multivariate analyses, Tocher and average linkage (UPGMA) cluster analyses, based on generalized distance of Mahalanobis, to quantify divergence in addition to Singh criterion to validate trait with the most contribution. The multivariate methods were consistent with each other, and the weight of 100 grains was the trait that contributed most to the divergence and had similar behavior in grain yield between hybrids in both years. Furthermore, this descriptor representing significant genetic variability for crossings and lines extraction to hybridization between BM 3061, ATL 200 and P 30B39 Y.

Abutment coating with diamond-like-carbon films to reduce implant-abutment bacterial leakage

Backgroud: The influence of diamond-like-carbon (DLC) films on bacterial leakage through the interface between abutments and dental implants of external hexagon (EH) and internal hexagon (IH) was evaluated. Film deposition was performed by PECVD (Plasma Enhanced Chemical Vapor Deposition). Sets of implants and abutments (N=180, n=30) were divided according to the connection design and the treatment of the abutment base: (1) no treatment (control); (2) DLC film deposition, and (3) Ag-DLC film deposition. Under sterile conditions, 1 µL of Enterococcus faecalis was inoculated inside the implants, and abutments were tightened. The sets were tested for immediate external contamination, suspended in test tubes containing sterile culture broth, and followed-up for five days. Turbidity of the broth indicated bacterial leakage. At the end of the period, the abutments were removed and the internal content of the implants was collected with paper points and plated in Petri dishes. They were incubated for 24 h for bacterial viability assessment and colony-forming unit (CFU) counting. Bacterial leakage was analyzed by Chi-square and Fisher exact tests (α=5%). The percentage of bacterial leakage was 16.09% for EH implants and 80.71% for IH implants (P<0.0001). The bacterial load was higher inside these implants (P=0.000). The type of implant significantly influenced the results (P=0.000), whereas the films did not (P=0.487). We concluded that: (1) IH implants showed a higher frequency of bacterial leakage and (2) the DLC and Ag-DLC films did not significantly reduce the frequency of bacterial leakage and bacteria load inside the implants.

Qualidade de vida de cirurgiões-dentistas que atuam no serviço público

Introduction: The quality of life of dentists has worsened over time, due to increased risks of labor and competitiveness in the labor market. However, there are only few studies about it. Objective: Investigate the perception of quality of life of dentists working in public service. Methods: In order to accomplish that, a cross-sectional study survey was conducted with 52 dentists of the professional permanent staff of the Municipal Health Service. The data were collected through structured questionnaire, validated, self-administered, proposed by the World Health Organization (WHO) in its shortened version, WHOQOL-Bref. Descriptive statistics and multiple regression were conducted, taking 95% as the confidence interval that characterizes the sample and the calculation of scores for each domain. Results: There was predominance of female subjects (76.9%) the majority of them aged 25 to 35 years (48.7%). Most professionals consider their quality of life good (82.7%), and were satisfied with their health (71.2%). Considering the measures of central tendency and dispersion, the physical domain (13.8) and Environment (13.8) had the lowest mean scores. All areas affected equally poor quality of life of research participants. The facets that showed the lowest values were the physical environment with 39.71 points and 53.92 points to financial resources. Conclusion: The majority of professionals were satisfied with their health and considered their quality of life good.

Qualidade de água utilizada para consumo em escolas e creches no município de São Carlos - SP

We know the importance of treating water for human consumption because changes in the physicochemical and / or biological has been associated with various health problems, the quality of water intended for human consumption must meet potability standards established by governmental decree 518/2004. The aim of this study was to evaluate the quality of water supplied schools and daycare in the city of São Carlos - SP. We selected 31 schools and kindergartens, and at intervals of 3 months, two water samples taken at three different points - network, tank and fi lter - totaling 186 samples, with an interval of three months, to verify possible differences in sampling points and at different times. The samples were evaluated for the following parameters: presence of total coliform and fecal coliform / E. coli count of heterotrophic bacteria, determination of pH, fl uoride, free residual chlorine, turbidity and color. The largest number of samples outside the standard for coliform was coming from the fi lters and the network, heterotrophic bacteria in most samples was taken out of standard fi lters. In the physical-chemical analysis of samples as many non-standard pH occurred in the network, network, and fl uoride in the fi lter pair in the fi lter to free chlorine and turbidity in the reservoir. The parameter with a larger sample size was inadequate fl uoride. We need more attention to the conservation, cleaning and maintenance of building reservoirs and fi lters in schools and kindergartens of San Carlos, since the water was considered unfi t for consumption.
