Aplicação do enxerto conjuntivo subepitelial para recobrimento de recessões em dentes inferiores

Some regions of the oral cavity present anatomical conditions that seem to hinder the result of gingival recessions coverage. Thus, the aim of this case report was to present two surgeries for gingival recessions coverage in the mandibular teeth performed on the same patient with the follow-up of 24 months. Patient RP, 35 years old, male, Caucasian, nonsmoker, systemically healthy, sought care at the clinic of specialization course in Periodontics from the Araraquara Dental School (Foar-Unesp). His main complaint was the gingival recessions within the lower teeth 33, 34, 35, 43, 44 and 45. Besides the aesthetic nuisance, the patient reported occasional dentin sensitivity. For resolution of the case was referred to the technique of subepithelial connective tissue graft associated with a coronally advanced flap. After 2 years of surgery, it was observed an excellent root guards with significant aesthetic improvement of the case. It can be concluded that the subepithelial connective tissue graft technique was effective in covering of type class I gingival recessions of Miller, even in a region that provides a difficult procedure.

Recobrimento radicular para o tratamento de hipersensibilidade dentinária cervical persistente

Gingival recession has a high prevalence in the population. This alteration may promote several complications such as cervical dentinal hypersensitivity (HSDC), carious and non-carious cervical lesions, and cosmetic changes due to the increase of the clinical crown length. To treat HSDC there are several therapeutic possibilities that should aim to eliminate pain after external stimulus. Treatment of this alteration can be performed by a conventional or invasive procedure, depending on the clinical condition and patients' desires. In situations where aesthetics is not the main complaint and HSDC persists even after conservative procedures, it is possible to indicate a procedure to achieve root coverage in Miller's Class I and II recessions. The aim of this paper is to report a case where the HSDC was not eliminated by conventional methods, which was resolved only after performing a minimally invasive surgery that promoted total root coverage.

A revisão das antinomias na psicologia: do racionalismo cientificista ao estruturalismo

In this essay, we sustain the idea that structuralist thinking is part of spontaneous criticism against the reductionisms that surround psychology. We depart from the radical split-up between the scientific viewpoint and that of metaphysics, expressed in the end-19th century scientific psychology projects. Next, we highlight the importance of the structuralist perspective in the review of the antinomic relations between the subjective and objective, operated at the heart of psychology throughout the 20th century. We show that the rejection of unilineal causality in favor of network causality curbed the advancement of unilateral or reductionist theories in psychology. Moreover, we consider the idea of structure as a point of convergence between psychology and philosophy. More than its explanatory nature, the notion of structure reveals an epistemological register capable of re-approximating psychology to the relativization of the ideal of scientific neutrality. The importance of structuralist thinking in psychology makes us consider the history of psychological knowledge as a type of research that belongs to cultural history.

Merleau-Ponty e a condição do natural em nós

In this paper, the aim is to highlight and analyze certain moments in the work of Merleau-Ponty when discussions took place about the condition of the natural in us. We mainly focus on the observed opposition between the evolutionist viewpoint adopted in The structure of Behavior and the perspective in the Phenomenology of Perception, based on the body as expression. We also look at studies on infantile prematuration and mention the characterization of the human body in the philosopher’s courses on the notion of nature. We underline the expressive dimension of the natural in us, which emerges from Merleau-Ponty’s formulations. In addition, we evidence the importance of psychoanalysis in the Merleau-Ponty’s treatment of the corporeity problem.

Percepção e impercepção: a experiência sensível na tradição fenomenológica

In this paper, we circumscribe a domain of theoretical research on the combination dynamics between the dimensions of presence and absence, visibility and invisibility, which emerges in the phenomenology of perception as an essential trait which marks both our experience of the perceived world and our subjective and intersubjective experience. We prioritize a theoretical axis that integrates Edmund Husserl and Maurice Merleau-Ponty’s thinking into Renaud Barbaras’ recent contributions. To this philosophical framework, we link contributions especially of psychology, outlining the circular movement observed between the phenomenology of perception and phenomenological psychology, Gestalt psychology, psychoanalysis, cognitive sciences and neurosciences.

Lugar do imaginário do ver: diálogos a partir do espelho lacaniano

Lacan’s conception of the mirror stage involves a rich network of theoretical dialogues. Amidst this network, an idea of subject is drawn. The aim of this paper is to examine that idea, not inside Lacan’s work, but in the theoretical framework related to the theme under analysis. We are interested in situating certain methodological and anthropological aspects of the mirror stage in relation to its mediating theories. Our observations are focused on three authors: Wallon, Sartre and Merleau-Ponty. As early as in 1931, the first underlined the importance of the child’s experience in front of the mirror to study his/her psychogenesis. The second is considered a representative of a Cogito philosophy and, therefore, seems to serve as a counter-reference for the psychoanalyst. The third established a relation of mutual dialogue with Lacan, reinforcing the heuristic nature of confrontations between psychoanalysis and phenomenology.

Os primeiros trabalhos de Merleau-Ponty: convergência filosófica e diplopia metodológica

The discussion of different themes revealed in the initial works of Merleau-Ponty, which are especially relevant in debates on the foundations of psychology, demands a closer look at the strategically complicity, from a psychological viewpoint, between The Structure of Behavior and the Phenomenology of perception. That context constitutes the background for this article. Based on the prerogative of this complicity, the goal is to present a reading that highlights primordial issues to outline the philosophical intention of that author. Despite the use of distinct methodological perspectives, both are part of one single work project. They fit into the discussion of Cartesian antinomies in philosophy and depart from the delimitation of the same problem, i.e. that of perception, as a point of integration between the two fundamental orders of Descartes’ thinking: the soul and the body.

A noção de esquema corporal na filosofia de Merleau-Ponty: análises em torno da 'Fenomenologia da Percepção'

The Throughout the work of Merleau-Ponty, besides philosophical concepts and images of his thinking, some theoretical-anthropological devices exist that reveal his approximation of human sciences. That is the case of the notion of body schema. Interested in discussing the role the critical development of this concept may have played in the passage from the first phase of his work to the period when the philosopher finds himself able to outline a new ontology, in this paper, we study the presence of the body schema notion in the Phenomenology of perception. We show that, in this book, Merleau-Ponty unsubstantiates the notion under analysis which, from a cognitive core that organizes our bodily experience, turns into the expression of our body parts’ mutual permeability, but also of the body’s permeability towards the world and other people.

The endangered species Brycon orbignyanus: genetic analysis and definition of priority areas for conservation

Currently, biodiversity is threatened by several factors often associated with human population growth and the extension of areas occupied by human activity. In particular, freshwater fish fauna is affected by overfishing, deforestation, water pollution, introduction of exotic species and habitat fragmentation promoted by hydroelectric dams, among other environmental impact factors. Several action plans to preserve ichthyofauna biodiversity have been adopted; however, these plans frequently cover only a small number of species, and decisions are often made without strong scientific support. This study aimed to evaluate the genetic aspects of wild groups of Brycon orbignyanus, an endangered fish species, using microsatellites and D-loop regions to identify the genetic structure of the samples and to establish priority areas for conservation based on the genetic patterns of this species. The results indicated that the samples showed levels of genetic variability compatible with others studies with Neotropical fishes. However, the results obtained in the analysis of molecular variance (AMOVA) for microsatellites (F (ST) = 0.258) and D-loop (F (ST) = 0.234) and the interpopulation fixation index revealed that B. orbignyanus was structured in different subpopulations in the La Plata River basin; the areas with better environmental conditions also showed subgroups with higher rates of genetic variability. Future conservation actions addressing these sites should consider two different management units: the complex formed by the Ivinhema River, Upper Parana, Camargo Port and Ilha Grande groups; and the complex formed by the Verde River and Sucuriu River groups.

Influence of mobility models in precision spray aided by wireless sensor networks

Precision Spray is a technique to increase performance of Precision Agriculture. This spray technique may be aided by a Wireless Sensor Network, however, for such approach, the communication between the agricultural input applicator vehicle and network is critical due to its proper functioning. Thus, this work analyzes how the number of nodes in a wireless sensor network, its type of distribution and different areas of scenario affects the performance of communication. We performed simulations to observe system's behavior changing to find the most fitted non-controlled mobility model to the system.
