Staining of esthetic brackets by plaque disclosing solutions

AIM: To evaluate the staining of esthetic orthodontic brackets by plaque disclosing solutions. METHODS: Two types of brackets manufactured by GAC/DENTSPLY(r) were evaluated: ceramic (n=30) and polycarbonate (n=30). The brackets were divided into 6 groups. Two control groups (n=6) were immersed in absolute ethanol: GI - ceramic brackets and GII - polycarbonate brackets. Four experimental groups (n=12) were immersed in different plaque disclosing solutions: GIII (ceramic brackets) and GIV (polycarbonate brackets) were immersed in Replak(r); GV (ceramic brackets) and GVI (polycarbonate brackets) were immersed in Replasul "S"(r). Relative quantitative analysis of the influence of plaque disclosing tablets on bracket staining was performed using reflectance spectrophotometry of stain deposition. Exploratory analysis of the data was performed using Analysis of Variance (ANOVA) in a 2x2 factorial setup (bracket x immersion) with additional treatments (controls). RESULTS: The results demonstrated that the ceramic brackets presented the highest amount of staining when Replasul "S"(r) was used (pd"0.05). However, when Replak(r) was used, no statistically significant difference was found in comparison with the control group (p>0.05). For polycarbonate brackets, staining was detected for both disclosing solutions (p>0.05). CONCLUSIONS: The disclosing solutions caused stain formation on polycarbonate brackets and, under the tested conditions, use of Replak(r) on ceramic brackets did not cause staining.

Plaque control improves the painful symptoms of oral lichen planus gingival lesions. A short-term study

BackgroundLichen planus is a mucocutaneous disease with manifestation in the oral mucosa, the gingiva being one of the most affected regions. In some cases, the lesion may be painful and lead to fragility of the tissues, so that precise diagnosis and adequate treatment are indispensible factors for improving the clinical condition. The aim of this study was to evaluate the effectiveness of plaque control in the improvement of clinical features and painful symptoms of oral lichen planus with gingival involvement.MethodsTwenty patients diagnosed with gingival lichen planus confirmed by histopathological examination were selected. The patients were evaluated by a trained examiner, with regard to the clinical features of the lesions [Index of Escudier etal. (Br J Dermatol, 157, 2007, 765)]; painful symptoms (Visual Analog Scale); and periodontally, as regards the visible plaque and gingival bleeding indices. Periodontal treatment consisted of supragingival scaling and oral hygiene instruction, with professional plaque removal afterward for a period of 4weeks. The entire sample was evaluated at the baseline and at the conclusion of treatment, and the results were analyzed by the Wilcoxon nonparametric test.ResultsThe data demonstrated that the majority of patients were women (90%), with a mean age of 55.9years. Periodontal treatment resulted in statistically significant reduction (P<0.05) in the periodontal indices, with consequent improvement in the clinical features and painful symptoms of the lesions.ConclusionsIt was demonstrated that plaque control was effective in improving the clinical features and painful symptoms of oral lichen planus with gingival involvement.

Estratégia de Investimento baseada em padrões descobertos por mineração de dados em séries históricas de preços diários do Indice IBOVESPA e das ações da PETROBRAS-PN (PETR4.SA)

With the increase of stakeholders and consequently increase of amount of nancial transaction the study of news investment strategies in the stock market with data mining techniques has been the target of important researches. It allows that great historical data base to be processed and analysed looking for pattern that can be used to take a decision in investments. With the idea of getting pro t more than the real indexs' gain, we propose a strategy method of transactions using rules built by algorithm classi cation. For that, diary historical data of Ibovespa index and Petrobras stocks are organized and processed to nding the most important attribute that act decisively when taking a investment decision.To test the accuracy of proposed rules, a non real portfolio management is created, showing the decisions' performance over the real index and stocks' performance. Following the proposed rules, the results show that the strategy of investment give me back a high return that Stock market's return. The exclusive characteristics of algorithms maximize the gain inside the analysed time allowing to determine the techniques' return and the number of the days necessary to double the initial investment. The best classi er applied on the time series and its use on the propose investments strategy will demand 104 days to double the initial capital

Indicadores de qualidade na educação básica: uma discussão a partir dos documentos Indicadores de qualidade na educação da ação educativa e Indice de desenvolvimento da educação básica (IDEB), do MEC

O presente trabalho tem como finalidade discutir o conceito de qualidade em educação a partir dos indicadores propostos pelo Ministério da Educação e Cultura (MEC) e pela Ação Educativa, através da conceituação da ideia de indicadores de qualidade em educação e seus objetivos; da definição o percurso histórico do conceito de indicadores de qualidade em educação e da análise dos indicadores de qualidade em educação propostos pelo documento da Ação Educativa e do MEC, além de analisar formas de avaliação da qualidade da educação propostas pelas duas instituições. Esta pesquisa de natureza qualitativa se constituiu de uma pesquisa qualitativa envolvendo pesquisa bibliográfica e analise documental acerca do tema “Indicadores de Qualidade na Educação Básica”. Para tanto, a presente pesquisa buscou utilizar-se das publicações oficiais como “Indicadores de Qualidade em Educação”, da Ação Educativa e o “Índice de Desenvolvimento na Educação Básica”, do MEC, como fonte documental. A etapa seguinte envolveu o levantamento e seleção das informações relevantes para o tema proposto nesta pesquisa, evidenciando os dados relativos a critérios, formas de aplicação e metodologia usados nos documentos pelas instituições acima citadas que tratam da questão da qualidade em educação no país. A análise dos documentos mostra diferentes formas de avaliação da qualidade da educação, envolvendo quesitos quantitativos como as médias obtidas nas disciplinas de português e matemática, ou ainda, a partir da participação da própria comunidade escolar

The effect of chlorhexidine on plaque index and mutans streptococci in orthodontic patients: A pilot study

Aim: The purpose of this study was to assess chlorhexidine effects on plaque index and salivary levels of mutans streptococci (MS) when used as the immersion solution for removable orthodontic appliances and added to their acrylic resin composition. Methods: Forty-five patients (6 to 12 years old) were randomly assigned into three groups with 15 patients each. Group I (control)—without orthodontic appliances disinfection; Group II—removable orthodontic appliances which had been immersed in 0.12% chlorhexidine digluconate overnight (8 hours), and Group III—orthodontic appliances in which 0.12% chlorhexidine digluconate solution had been incorporated into their resin composition. Saliva was collected for quantification of MS and evaluation of plaque index was performed before and after installation of orthodontic appliance at 0, 2, 4, 6, 8, and 10 weeks. Data were analyzed by using analysis of variance. Results: Number of MS colonies in saliva and plaque index showed no statistically differences among groups at the different periods (p > 0.05). Conclusions: It could be concluded that chlorhexidine incorporation into the acrylic resin of removable orthodontic appliances at 0.12% concentration and immersion of the appliance into 0.12% chlorhexidine solution were not effective in reducing plaque index and the number of MS in saliva.
