Estudo hodológico das aferências ao primeiro núcleo do circuito neural do reflexo auditivo de sobressalto: núcleo da raiz coclear

Las neuronas de la raíz coclear son las primeras neuronas del sistema nervioso central a recibir la información auditiva proveniente de la cóclea y se conectan con centros de integración sensoriomotora del tronco encefálico, especialmente con el núcleo reticular caudal del puente. Funcionalmente las neuronas de la raíz coclear están envueltos en el circuito elemental del reflejo auditivo de sobresalto juntamente con las células ganglionares del órgano de Corti, el núcleo reticular caudal del puente y las motoneuronas de la médula espinal. El reflejo auditivo de sobresalto presenta una serie de modulaciones como la habituación, la sensibilización, la inhibición por estímulo previo y la potenciación por un estímulo adverso. Las alteraciones en la reacción refleja de sobresalto y sus diferentes modulaciones poseen valor diagnóstico en la clínica médica de enfermedades neurodegenerativas y psiquiátricas como Parkinson y Esquizofrenia. Las modulaciones del reflejo auditivo de sobresalto ocurren mediante la influencia de diversos núcleos sobre los componentes del circuito elemental de este reflejo. El núcleo menos estudiado del circuito neural del reflejo auditivo de sobresalto es el núcleo de la raíz coclear. El patrón de conectividad eferente de las neuronas de la raíz coclear es bien conocido, sin embargo poco se conoce sobre los orígenes de sus aferencias y la identidad neuroquímica de las mismas. Estudios previos demostraron que el soma y en las dendritas de las neuronas de la raíz coclear están cubiertos por botones sinápticos de cuatro tipos, sugiriendo que existan diversos orígenes para estos terminales axonales, con características neuroquímicas propias. El conocimiento de las aferencias a las neuronas de la raíz coclear es relevante para comprender cual el papel del núcleo de la raíz coclear en las modulaciones del reflejo auditivo de sobresalto. Por lo tanto, ...

Características de las experiencias españolas de presupuesto participativo: intento de encuadramiento en una tipología

Participatory Budgeting (PB) is an innovative methodology of public budget management. It includes the common citizen in decision-making process, which does not happen in traditional budget processes. PB emerged in Brazil in the last two decades of the last century (Porto Alegre’s experience is the best known model) and spread to several countries since then. The spread of the practice has produced significant changes in relation to the original proposals, requiring the efforts of analysts to identify them in different situations, carried out by different political actors, with different objectives. Pires and Pineda (2008a) proposed a typology of PB sought to contemplate the experiences from the simplest to the most daring and less sophisticated to the pretentious, so as to allow assessment of the maximum number of cases. In this article the Spanish experiences of PB are characterized from this typology, highlighting its most relevant aspects. It is a useful study to understand the evolution of PB in Spain, but also to continue the effort to better define what is and can become the participatory budget as a possible tool for improving the management of local public finance and democracy

Effect of different bleaching protocols on dental enamel and composite resin

To evaluate changes in microhardness, roughness and surface morphology of dental enamel and composite resin after different tooth bleaching techniques. Material and Methods: Dental fragments from bovine incisors with composite resin restorations were submitted to different bleaching protocols: G1 – daily 8 hours application of a 10% carbamide peroxide (CP) gel during 21 days; G2: 3 applications of 15 minutes of a 38% hydrogen peroxide (H2O2) gel; G3: 38% H2O2 gel associated to irradiation with LED (470nm) during 6 minutes. The Knoop micro hardness of enamel and composite resin were evaluated at 1, 7, 14 and 21 days for G1, and after 1, 2 and 3 sessions for G2 and G3. The roughness and superficial morphology (atomic force microscopy) were evaluated before and at the end of the bleaching treatment. The data were analyzed by Mann-Whitney and Wilcoxon tests (=5%). Results: Significant reduction on enamel hardness was observed after 2 and 3 sessions for G2 and G3. For composite, the reduction occurred after 21 days for G1, and after 3 sessions for G2 and G3 (p<0.05). Significant reduction on roughness and superficial morphology were observed only for enamel of G1 group (p<0.05). Conclusion: The 10% CP gel promoted only superficial alterations on dental enamel, while the 38% H2O2 gel promoted mineral reduction of this dental tissue. All the bleaching protocols promoted reduction on hardness of composite resin.

Displasia ectodérmica hipohidrótica: un síndrome de interés para la odontología

Hypohidrotic ectodermal dysplasia (HED) is a rare disease of genetic etiology. The most frequent form is of recessive linked to X-chromosome inheritance with affected male and female carriers. It can occur through autosomal mutations, of the gene EDA1 gene being responsible for the majority of the cases. It is characterized by the triad: hypohidrosis, oligodontia and hypotrichosis. We present two cases of patients with HED in which we observed characteristic signs of this syndrome: delicate skin, sparce hair, eyebrows and eyelashes, periorbital wrinkles, perioral and periorbital hyperpigmentation, prominent lips, in addition the patient in case 2 also present the depressed nasal bridge. We also found decreased salivary and lacrimal secretion and maxillary hypoplasia in both cases. At the oral examination in case 1 the upper right and left deciduous canines and lower right deciduous canine were present, and in case 2 the upper and lower (right and left) deciduous canines and two upper (one right and other left) permanent incisors were present with altered morphology, all of these dental elements were healthy. The early dental treatment of patients with HED, especially in the presence of oligodontia, as observed in our cases, is important not only to provide a better quality of life for these patients in the short term, but also an attempt to minimize the changes in facial growth to which these patients are subject.

Estudio descriptivo in vitro de dos agentes blanqueadores de distinta concentración sobre la micromorfología del esmalte bovino

Dental tooth bleaching is a conservative option for the treatment of tooth stains. It is based on the use of hydrogen peroxide as an active agent. Despite its effectiveness to lighten tooth colour, there is concern regarding its use due to the effects it could have over enamel surface. There is scarce evidence on the subject and contradictions exist between different authors. The aim of this study was to compare enamel surface micromorphology after bleaching teeth with different concentrations of hydrogen peroxide solutions. Method: 50 healthy bovine incisors sectioned horizontally at the cemento-enamel junction were prepared. Contents of pulp chamber and tooth surfaces were cleaned. The buccal surface of each tooth was divided vertically, assigning one half to the control group (CG) and the other randomly to: Group 1: 25 samples treated with 15% hydrogen peroxide with nitrogen doped titanium dioxide. Group 2: 25 samples treated with 35% hydrogen peroxide. Square samples (2x2 mm.) were obtained and observed by SEM (magnification of 5.000x and 10.000x). Results: All treated groups showed longitudinal depressions on the surface and increased surface roughness. Conclusions: Tooth bleaching with hydrogen peroxide produces subclinical alterations over bovine enamel surface. 15% hydrogen peroxide bleaching agent produced less micromorphology alteration over bovine enamel surface than the 35% hydrogen peroxide agent.

Estado actual del blanqueamiento: sigue siendo un tratamiento seguro? review

The demand for cosmetic dentistry, including teeth whitening, has increased in recent years. The home teeth whitening and in-office, are widely used in dental practice. The mechanism by which it works is by oxidation of the chromogenic existing tooth structure. This is an effective and minimally invasive procedure that achieves tooth lighten the color, however, may cause alterations in the enamel surface, such as a dental permeability increase. Another effect caused by this procedure is tooth sensitivity, being the most common side effect, up to 65% of individuals have had a secondary effect at least once during treatment. This sensitivity and gingival irritation caused by bleaching may vary depending on the patient and used bleaching product

Deformación del área de corte de las limas endodónticas sometidas a diferentes métodos de precurvatura

Objetive: Evaluate the deformations caused in the cutting edges in the K-file #25 (LK), subjected to pre-beinding of the apcial third using the following methods: finder-bending, cotton-pliers bendin and Flexobend, observed under scanning electron microscopy (SEM). Material and methods: Forty-eight LK#25 were divides into 4 groups (n=12); G1, control; G2, finger-bending; G3, cotton-plier bending, G4, Flexobend. The curvature was standardized in the apical segment of the file at 2 mm of D!. Was constructed a model of acrylic resin that correspond to a canal of 20º of curvature. The files were examined under SEM (260X). Data were analyzed using Fisher´s statistical test with a significance level of 5%. Results: The images showed no alterations in the LK, similar to G3, with no statistical difference. G3 and G4 were statistically different form the other groups (p<0.05). Conclusions: the finger-bending method to curve apical third of LK #25 did not alter the cutting edges, the cotton-pliers bending and Flexobend did alter the cutting edges of the files (AU)
