This paper aims at establishing a link between the psychoanalytic idea of a clinical setting and the notion of framing in the artistic image. To this end, the reading is based on issues related to clinical care, in the specific sense of a setting, casting itself in artistic creations that challenge the rigid status – when it’s the case – of this setting, and reflecting on the notion of transference, a basic phenomenon in this context. The conclusions refer to a direct approach between the aesthetic experience and psychoanalytic experience.

This paper wishes to reintroduce, in a brief manner, a subject which has been neglected in the recent past: the history of Classical Studies in colonial Brazil. As an introduction to this complex issue, it aims at a historical review of the ideal of humanitas in the Academias of the eighteenth century. The presence of this ideal in the Academias is seen as a result of the classical education of the Brazilian people, a process which begins with the arrival of Jesuit missionaries in 1549 and 1553. In our discussion, we shall use the ideas of Dante Tringali (1994), Fernando de Azevedo (1958), Antônio Cândido (1977), José Aderaldo Castello (1969), among others.

In view of the diversity of environments found in the Brazilian territory, it is understandable that the use of native species can provide more relevant information for ecotoxicological studies. The purpose of this work was to evaluate the quality of water samples from the Atibaia River in an area that is under the influence of petroleum refinery using a native test-organism and submitting the data to PCA statistical analysis. Therefore, acute toxicity assays with Lecane bulla (Rotifera) were performed in four locations of the river, as well as physical-chemical analyses. Sampling was drawn in the dry and rainy seasons. The bioassays were static and lasted 48 hours; dead organisms were quantified at the end of the tests. Toxicological differences among the samples/per location and control were compared by means of the Analysis of Variance. Physical-chemical and mortality variables were simultaneously analyzed by multivariate analysis of the principal components and the Pearson correlation coefficient. Water samples from the exit of the refinery stabilization pond (location S.1) were toxic to L. bulla in both seasons, with significant differences in relation to the control and between the seasons. The statistical treatment of data showed that mortality was strong and positively correlated with total hardness, chlorides and EC, which together with pH presented higher values in location S.1, in the dry and in the rainy seasons. Due to its sensibility to the quality of the Atibaia river water samples, the potential use of L. bulla for ecotoxicological studies as an alternative test organism could be demonstrated.

Dermoid cyst of the floor of the mouth is an uncommon lesion that presents as a solitary mass, painless, with no history of fever or drainage, usually in the midline, and commonly in the upper level space mylohyoid. In this paper, the authors describe two patients with the same clinical presentation: a large mass in the floor of the mouth that does not regressed, resulting in dysphagia and dyspnea. The treatment was carried out in both complete surgical removal through an incision in the ventral surface of the tongue.

There are few studies that evaluate the legal aspects, consent forms and ethical considerations facing implantology. This paper reviews and discusses the most important criteria in relation to the care of patients needing dental implants. Used the following databases: Medline (Pubmed), Dentistry Oral Science , Scielo, Athenas (Dissertation / Thesis), Digital Library of UNICAMP (Dissertation / Thesis), Digital Library of USP (Dissertation / Thesis) over the past 15 years . The inclusion and exclusion criteria were clinical articles, resulting from expert opinion on the subject of review and longitudinal follow-up who have studied or reported on the ethical aspects in implant dentistry; were excluded studies whose language was not English or Portuguese. Of a total of 52 articles and theses, after an analysis according to inclusion and exclusion criteria, 26 were selected. The literature shows that the safe practice of implantology is indispensable for the success of therapy. Respect the ethical, legal and make it explicit relationship with the patient (informed consent, information) are an important factor in the success of rehabilitative treatment. Since this treatment is long term, professional dental implant requires all documentation and clarity in time to offer treatment to the patient and professional expectations are met.

The aim of his study was to review the current scientific literature in order to discuss the surgical, prosthetics and psychological/psychosocial aspects during the treatment planning of edentulous patients, when a total fixed prosthesis or overdenture is indicated. To identify studies to take part in this review, a search was conducted for the following databases: PubMed, Dentistry and Oral Sciences Source, Journals@Ovid, SpringerLink, Wiley Online Library, Nature (NPG), Oxford Journals. It was used as descriptors: total fixed prostheses and overdentures. Inclusion criteria were: clinical articles, clinical case reports, case series, literature reviews and systematic reviews that addressed the study and comparison of total fixed prostheses and overdentures for a surgical- prosthetic planning. Exclusion criteria were: laboratory and in vitro studies and those whose first language was not English or Portuguese. Of a total of 454 articles, after an analysis according to inclusion and exclusion criteria, 76 articles were selected. During an implantsupported prosthesis rehabilitation with dental in edentulous patients, the use of alternative procedures appear to be effective when compared to more invasive surgical techniques, and thus, the amount of dental implants possible to install associated with prosthetic issues such as lip support, smile line, quantity and quality of mucosa, phonetics, etc., will allow an appropriate treatment planning to each clinical case

OBJECTIVE: The aim of this study was to gather information and discuss the predictability of implant-supported prostheses in patients with bruxism by performing a literature review. METHODS: In order to select the studies included in this review, a detailed search was performed in PubMed and Medline databases, using the following key words: bruxism, dental implants, implant supported prosthesis, and dental restoration failure. Items that were included are: case reports, randomized controlled trials, in vitro studies, literature and systematic reviews, with or without meta-analysis, of the last 20 years that addressed the theme. Articles without abstracts, animal studies, articles in languages other than English and articles from journals unrelated to the dental field were excluded. RESULTS: after analysis according to inclusion and exclusion criteria, 28 articles were selected from a total of 54. It is known from the array of scientific articles which have assessed, either through retrospective, prospective or experimental studies, that the biomechanical and biological impact of bruxism on implant-supported prostheses is small, and that the literature has contributed little to exemplify the prosthetic limits of safety for the specialist from a clinical point of view. CONCLUSION: Although there is still no general consensus on this matter, most of the literature review articles do provide clinical guidelines that contribute to implant supported prostheses longevity and stability in patients with bruxism.
