Influência do hipoclorito de sódio no processo de reparo de dentes de cães tratados em sessão única

Introdução: a eliminação de bactérias dos canais radiculares é essencial no tratamento endodôntico de dentes com polpas necrosadas, desde que bactérias não só causam, mas também mantêm, as lesões periapicais. Objetivo: analisar in vivo a influência de soluções irrigantes (NaOCl 1%, NaOCl 2,5%, solução salina estéril 0,9%) no tratamento de dentes de cães com lesão periapical crônica em sessão única. Métodos: quarenta canais radiculares de três cães da raça Beagle permaneceram expostos à cavidade bucal para permitir a contaminação e a formação de lesões periapicais crônicas. Em seguida, os canais radiculares foram preparados biomecanicamente. Durante a instrumentação, três soluções irrigantes foram utilizadas: G1 – NaOCl 2,5%; G2 – NaOCl 1%; G3 – solução salina estéril 0,9%. O grupo controle (G4) não recebeu tratamento nem selamento coronário. Os canais radiculares foram obturados com cones de guta-percha e Sealapex. As aberturas coronárias foram seladas com IRM e amálgama. Após 6 meses, os animais foram sacrificados e blocos de tecido processados histologicamente para serem corados com hematoxilina e eosina, ou Brown e Brenn. Resultados: não houve diferença histológica significativa entre a utilização de hipoclorito de sódio a 1% ou 2,5% (p>0,05), mas houve entre eles e a solução salina estéril a 0,9% (p<0,05). Conclusão: concluiu-se que o uso de soluções irrigantes com potencial antibacteriano (hipoclorito de sódio a 1% e 2,5%) proveu condições mais favoráveis ao processo de reparo.

Avaliação clínica do clareamento no consultório: técnica de aplicação única do agente clareador

This study aimed to evaluate the clinical effectiveness of two bleaching agents without changing the whitening gel during the clinic session 1X45minutos. 10 patients were selected according to the criteria of inclusion and exclusion and upper arch of the patients were divided into two quadrants (n: 10), G1: gel clareador Clàriant Office (hidrogênio35 Angellus) peroxide% (PH) in superior right side (LD) and the gel WhitenessHp Blue (FGM) PH 35% on the superior left side (LE. 2 clinical sessions were accomplished, 45 minutes each, with an interval of one week between sessions. At first the bleaching treatment patients received prophylaxis, molding to guide measurement of color with condensation silicon and the color evaluation through the apparel spectrophotometer VITA Easyshade (Vita Zhanfabrik, Alemanhã). 14 days after the end of the bleaching treatment was performed the measurement final color of the teeth. The patients reported sensitivity in scale 0-4. The result showed that through T Test comparing quadrants presented no statistical differences (p>0,05) in relation to coloration and dental sensibility. It can be concluded that the materials evaluated are effective for bleaching vital teeth with low tooth sensibility.

Classe mollicutes na boca de pacientes com dependência química

Drug addiction is one of the biggest public health problems worldwide, not only by the dimensions of the problem, but also by the severity of the damage, creating favorable conditions for opportunistic microorganisms such as class Mollicutes. This study aims to evaluate the presence of the main species and genera of this group in the subgingival biofilm of drug addiction patients, comparing them with non-dependent subjects. For this purpose, data on systemic health conditions, socioeconomic characteristics, drug addiction from 72 patients with drug addiction kept in rehab clinics and 100 non-dependent patients who formed the control group were obtained. Intra and extraoral clinical examinations were performed and samples of subgingival plaque were collected through sterile absorbent paper cones. The presence of different genera and species of the class Mollicutes was evaluated by PCR using the specific primers and conditions for each microorganism. The statistical analysis was performed using the Chi-square test for comparisons of three or more variables and the Mann-Whitney test, with significance level of 5%. Out of species and genera evaluated, Mycoplasma salivarium showed correlation with gingival inflammation in both patient groups and was more frequently detected among drug addiction patients

O momento oportuno para a abordagem ortodontica no tratamento da classe II

Because it still brings polemic among the professionals, it was mention once more, in this literature review, the theme that aims to define the appropriate timing to approach the bad occlusions of Class II, and also when it would the right opportunity to treat them, in way that would convey to the patient consistent, stable results in a long term. These are important aspects to be taken into consideration by orthodontists, either by those who defend the early treatment or by those who defend the late treatment. Therefore, the present study aims to aid the clarification of daily doubts regarding this aspect.

Levantamento histórico da Classe Tentaculitoidea no Devoniano brasileiro: principais características e padrões de preservação

This work deals with the historical survey of the class for the Devonian layers, general characteristics of the group and taphonomic preservation standards associated with the group. It was analyzed specimens of scientific collections from brazilian museums and universities. The taxonomic group is represented by four genera in the basins of Parana, Parnaiba and Amazon: Tentaculites, Homoctenus, Styliolina and Volynites. The tentaculitids occur from Ordovician to the Devonian, having its peak in the Middle Devonian. The class has three known orders: Tentaculitida, animals of benthic habit, Homoctenida and Dacryoconarida, animals of habit planktonic. It was also noticed the presence of two patterns of taphonomic conservation: isolated and grouped specimens.

Desgaste de dressadores de ponta única fabricados em diamante

Os dados para este estudo foram obtidos mediante a implantação de um sistema de monitoramento por emissão acústica em uma retificadora plana tangencil. A dressagem foi realizada em rebolos convencionais e os resultados foram analisados tomando por base a relação com o desgaste volumétrico sofrido pelo diamante do dressador. As análises foram realizadas nos diamantes naturais dos tipos Brasil Extra e Mato Grosso e no sintético do tipo CVD. Os dados da emissão acústica de cada dressador foram divididos em faixas de frequência para filtrar possíveis interferências. Utilizando a faixa mais apropriada, foi possível elaborar uma curva característica para cada dressador e relacionar o desgaste do diamante com o sinal RMS da emissão acústica na faixa de frequência analisada.

Revolução constitucionalista de 32: principais motivações da Frente Única Paulista

This paper aims to analyze the Constitutionalist Movement in 1932, trying to understand, more specifically, the political end sought by the Front Unique Paulista, on a literal translation, union of the political parties of São Paulo (Republican Party Paulista and Democratic Party). The research is motivated by the need to understand the political project of FUP with the movement and the existing motivations why it was articulated. The comprehension of the constitutionalists' reasons is relevant to understanding the history of the revolution, from its origin to its outcome. Based on literature and its historical analysis, the paper will demonstrate that the Front, with the advent of the Constitutionalist Revolution of 1932, had as its main purpose regain political control of the state of São Paulo lost with the revolution of 1930. More than the vaunted concern with the implementation of a new constitution for the nation, the FUP leaders had intended to retrieve the lost power with the movement of 30 and the rise of Getulio Vargas to power. Under a banner to fight for a new constitution and the expected change from a totalitarian and centralized state imposed by Vargas for a more autonomous state, the cause of São Paulo enticed sympathy and support from the community, whose social history always harbored separatist ideas, even that they have never been carried out to its ultimate consequences

Influência do ambiente no desenvolvimento de colônias iniciais de formigas cortadeiras (Atta sexdens rubropilosa)

Annually, mature colonies of Atta ants produce winged males and females, where leave the colony in which they were produced to form new colonies and thus continue the species perpetuation. The foundation of Atta spp. colonies always involves high queen effort, solely responsible for growing the fungus and the care with itself and its offspring. During the foundation there is consumption of body reserves. This study investigated how the environment influences the development of newly founded colonies of leaf cutting ant, Atta sexdens rubropilosa. Therefore, it was compared field colonies collected five months after the nuptial flight and colonies maintained in the laboratory since the nuptial flight. It was analyzed the weight and size of the population (number of workers, larvae, pupae and eggs), the workers size, the volume and weight of the fungus garden and queen effort for the nest foundation (lipid content and weight of queens). In comparison to the field colonies, the laboratory colonies showed higher values in the weight and size of population, the volume and weight of the fungus garden. Measures of workers by class size did not vary between colonies from field and laboratory. The queen effort for nest foundation was higher in field colonies, which showed a lower percentage of fat and lower weight compared to laboratory colonies. These results show that the environment has a strong influence on the colonies development during the foundation, as well as on the physiological status of the queens, and therefore the survival, development and success of the colony, it is a reflection of the queen efforts and of the environment conditions.
