O comportamento prosódico dos monossílabos no português arcaico por meio das Cantigas de Santa Maria

This paper aims to conduct a study on the prosodic behavior of monosyllables in Medieval Portuguese. This research is based on an innovative methodology that observes the relation between musical and linguistic prominences and its contributions for data collection regarding the prosodic structure of the language in study. There are in Medieval Portuguese heavy (tonic) monosyllables and light (atonic) monosyllables with diverse syllabic structure. The onset is irrelevant for the syllabic weight. Monosyllables with a consonant in the coda are heavy unless this consonant represents an inflexion element. Monosyllables with no consonant in the coda are normally light but there are also heavy monosyllables with no consonant in the coda.

Proparoxítonas no português arcaico: uma análise por meio da música e do texto das Cantigas de Santa Maria

This paper aims to conduct a study on proparoxytones in Medieval Portuguese through an innovative methodology based on the observation of coincidences and no-coincidences of musical and linguistic prominences of poetic texts with musical notation.. This methodology allowed us to verify the existence of a hundred and thirteen proparoxytones words in a corpus constituted by the first hundred Cantigas de Santa Maria. It was possible to locate the stressed syllable in 92,93% of the found words.

Efficiency of cares over toothbrush storage to prevent contamination

This study evaluated the efficiency of a toothbrush holder to prevent contamination of toothbrushes used by preschool children. For that, the sample was composed by children 6 years old, enrolled in an educational and recreational center in Araraquara/SP, and divided into 3 groups: G1: same continuing routine storage toothbrushes, G2: children received only a new toothbrush holder for storage; G3: they received new toothbrushes holder for storage and solution of chlorhexidine digluconate to 0.12% to dabble in the toothbrush after use. After brushing their teeth, toothbrushes were collected for microbiological analysis. The data were analyzed using the distribution of frequencies. It was observed that, in general, higher prevalence of the microorganism in the toothbrushes was Streptococcus viridans (58.97%), followed by Estafilococcus (35.90%), the bacillus of air (28.21%) and Neisseria mucosa (5.13%). Evaluating frequency, it was noted that the contamination presented by Streptococcus is higher in G1 when compared to G2 and G3, while for Estafilococcus, the presence was more significant in G3. Thus, it was concluded that the use of new toothbrushes holder able to avoid direct contact between brushes and allow drying without smothering could be an excellent alternative to educational institutions that require the storage group.

Atividade antimicrobiana residual de pastas à base de hidróxido de cálcio e associações como medicação intracanal

A resistência do biofilme endodôntico pode requerer um período maior de permanência da medicação intracanal a fim de prolongar sua ação antimicrobiana. O objetivo deste estudo foi avaliar a ação antimicrobiana residual das medicações intracanal: G1) hidróxido de cálcio + soro; G2) Calen; G3) Calen + PMCC; G4) Calen + clorexidina 0,4% e G5) clorexidina gel 2% frente à Enterococcus faecalis, Candida albicans, Pseudomonas aeruginosa, Staphylococcus aureus e Kocuria rhizophila em 60 canais radiculares bovinos. Os canais radiculares foram instrumentados e preenchidos com as medicações intracanal, as quais foram removidas após os períodos experimentais (15, 30, 60 e 90 dias) e empregadas na técnica de difusão em ágar. Os halos de inibição foram evidenciados por gel de TTC e então mensurados. Os dados de halos de inibição foram submetidos à análise estatística dos testes Kruskall-Wallis e Dunn, com nível de significância de 5%. O Ca(OH)2 + soro apresentou efeito até o período de 15 dias. A pasta Calen demonstrou efeito residual aos 60 dias frente ao S. aureus, enquanto Calen/PMCC até o período de 90 dias frente à S. aureus e K. rhizophila e aos 30 dias para E. faecalis. A pasta Calen associado à clorexidina foi efetiva frente à E. faecalis até o período de 60 dias. A clorexidina gel 2% apresentou ação residual em todos os períodos, com exceção de E. faecalis aos 90 dias, também apresentou atividade antimicrobiana mais prolongada, seguido das associações do hidróxido de cálcio com clorexidina e PMCC.

A misosoginia medieval e seus ecos nos Lais de Maria de França

The Lais of Marie de France are a specific type of historical record about the medieval aristocratic society and enables us to decipher the hierarchies that govern the relationship between men and women in the period. As well explains Georges Duby, medieval society tends to present coated with a male character because, among other factors, its latent misogyny. Women were placed under male authority, convinced of their natural superiority , the men despised , mocked her sex , meanwhile feared them, after all, women were Eve’s daughters. So, Lais offer female images that cannot be ignored , since it express the author women’s idea. However , as we seek to demonstrate in this article, Maria of France reflects the representations of the Christian society aristocratic. One note here that this article does not aspire to reach the actual circumstances, but the historical significance of female images present in the Lais.

Effect of moisture on dental enamel in the interaction of two orthodontic bonding systems

OBJECTIVE: The purpose of this study was to assess by means of scanning electron microscopy (SEM) the remaining adhesive interface after debonding orthodontic attachments bonded to bovine teeth with the use of hydrophilic and hydrophobic primers under different dental substrate moisture conditions. MATERIAL AND METHODS: Twenty mandibular incisors were divided into four groups (n=5). In Group I, bracket bonding was performed with Transbond MIP hydrophilic primer and Transbond XT adhesive paste applied to moist substrate, and in Group II a bonding system comprising Transbond XT hydrophobic primer and adhesive paste was applied to moist substrate. Brackets were bonded to the specimens in Groups III and IV using the same adhesive systems, but on dry dental enamel. The images were qualitatively assessed by SEM. RESULTS: The absence of moisture in etched enamel enabled better interaction between bonding materials and the adamantine structure. The hydrophobic primer achieved the worst micromechanical interlocking results when applied to a moist dental structure, whereas the hydrophilic system proved versatile, yielding acceptable results in moist conditions and excellent interaction in the absence of contamination. CONCLUSION: The authors assert that the best condition for the application of primers to dental enamel occurs in the absence of moisture.

Endodontics pastes formulated with copaiba oil: action on oral microbiota and dentin bridge formation in dogs

This study analysed the effect of pastes formulated with calcium hydroxide P.A. and different vehicles (saline solution - paste A and Copaifera langsdorffii Desfon oil - paste B) on oral microorganisms and dentin bridge formation in dogs. The antimicrobial action of the pastes and their components was analysed by the minimum inhibitory concentration in agar gel technique. The components were diluted and tested on fifteen standard strains of microorganisms associated with endodontic diseases. The microorganisms were cultivated and after incubation data was analysed using One-Way ANOVA and Turkey's test (P≤0.05). Four superior incisors of ten animals were used to evaluate dentin bridge formation. Two incisors were capped with paste A (GA) and two with paste B (GB). After 90 days, the teeth were extracted for histological analysis and the degree of dentin bridge formation evaluated. Data was analysed by the Kruskal-Wallis test (P<0.05). The pastes and their components were classified in the following decreasing order of antimicrobial action: calcium hydroxide P.A., paste A, paste B and Copaifera langsdorffii Desfon oil. Calcium hydroxide P.A. showed significantly higher antimicrobial action than the pastes or their vehicles. No significant difference was observed between the two pastes in dentin bridge formation. Based on the microorganisms studied, it can be concluded that the pastes analysed showed similar antimicrobial potential but differed significantly from their individual components. No significant difference was observed in dentin bridge formation between the different pastes tested.

Efeito da umidade no esmalte dental na interação de dois sistemas de colagem ortodôntica

Objetivo: a proposta desse estudo foi avaliar, por meio de microscopia eletrônica de varredura (MEV), a interface adesiva após a descolagem de acessórios ortodônticos, fixados em dentes bovinos com emprego de adesivo hidrofílico e hidrofóbico, em condições distintas de umidade do substrato dentário. Métodos: foram utilizados 20 incisivos inferiores, divididos em quatro grupos (n = 5): Grupo I , empregou-se o sistema de colagem contendo o primer hidrofílico Transbond MIP e a pasta adesiva Transbond XT, aplicados em substrato úmido; Grupo II, empregou-se o sistema de colagem primer hidrofóbico Transbond XT e pasta adesiva em substrato úmido; Grupos III e IV, os braquetes foram colados com os mesmos sistemas de união dos Grupos I e II, porém com esmalte dentário seco. Removidos os acessórios, avaliou-se em MEV, em diferentes magnificações, a interface adesiva e a interação dos sistemas adesivos com o esmalte dentário. As imagens foram avaliadas qualitativamente, observando-se o embricamento mecânico para o adesivo hidrófilo em quaisquer condições de substrato. Resultados: a falta de umidade no esmalte condicionado permitiu uma melhor interação entre os materiais de ligação e a estrutura adamantina. O adesivo hidrofóbico apresentou o pior resultado de interação micromecânica quando aplicado a uma estrutura dentária úmida; já o sistema hidrofílico mostrou-se versátil, obtendo resultados aceitáveis em condições de umidade e excelente interação na ausência de contaminação. Conclusão: os autores afirmam que a melhor condição do esmalte dentário para a aplicação de primers é com a ausência de umidade.
