Hipersensibilidade dentinária cervical: em busca de um tratamento eficaz

The knowledge of the etiology of any disease or condition is paramount to a safe and effective treatment. This literature review aims to show some options to treat dentine hypersensitivity (HSDC). The loss of cervical enamel and cementum exposure of tubules leads to a painful condition and patient discomfort, called HSDC. This loss of tooth structure occurs due to formation of cervical lesions in cases of gingival recession, abrasion, erosion, or abfraction by the association of two or more factors. Some treatments are not effective, but there are effective therapies, such as: application of ferric oxalate, potassium oxalate, potassium nitrate, fluoride varnish, solutions of calcium phosphate, adhesives and Bonding procedures. Therefore, the identification and removal of etiological factors is essential to successful treatment of HSDC normally associated to tubules obliterate and consequent reduction of fluid motion within the dentin.

Tratamento estético periodontal: revisão de literatura sobre alguns tipos de cirurgias

Currently, periodontal aesthetics has been prized for harmony of the smile. The clinical crown lengthening, gingival excess or altered passive eruption, is effectively corrected by periodontal surgery. The purpose of this paper is to show, through a literature review, some types of surgery on clinical crown lengthening and root coverage. Clinical crown lengthening is done to Change the size of the anterior teeth and to optimize the cosmetic result of treatment with new coronal restoration and other cosmetic dental care. In general, the treatment plan and the choice of operative technique begin with careful clinical examination. Recessions tissue can be defined as a displacement of the gingival margin toward the junction mucogingival exposing the root surface. These, when present, impacting on patient comfort by providing the occurrence of cervical dentin hypersensitivity, and the esthetic, the amendment of the gum line. Successful treatment of recessions is based on knowledge of its etiology and assessment of predictability of surgical techniques that aim to root coverage. Through literature review, we can conclude that the types of surgery most often used are: 1) to increase the clinical crown, gingivectomy, flap surgery and gingivoplasty osteotomy, and 2) for root coverage, the use will depend on the amount of gum keratinized and especially the classification of Miller.

Enceramento diagnóstico: previsibilidade no tratamento estético indireto

O enceramento diagnóstico é uma ferramenta de grande importância dentro da filosofia atual de excelência estética no tratamento restaurador indireto. Trata-se da reprodução em cera realizada a partir de um modelo de estudo e tem como finalidade observar, em três dimensões, a futura forma final dos dentes, ajudar visualmente na realização do preparo dentário e demonstrar ao paciente o resultado final do tratamento antes mesmo de iniciá-lo, obtendo-se, assim, máxima previsibilidade. O objetivo desse artigo é mostrar, através de casos clínicos, a previsibilidade no tratamento restaurador indireto obtida por meio do enceramento diagnóstico.

Diretrizes de conduta e tratamento de síndromes febris periódicas associadas à criopirina (Criopirinopatias–CAPS)

To establish guidelines based on cientific evidences for the management of cryopyrin associated periodic syndromes. The Guideline was prepared from 4 clinical questions that were structured through Pico (Patient, Intervention or indicator, Comparison and Outcome), to search in key primary scientific information databases. After defining the potential studies to support the recommendations, these were graduated considering their strength of evidence and grade of recommendation. 1215 articles were retrieved and evaluated by title and abstract; from these, 42 articles were selected to support the recommendations. 1. The diagnosis of Caps is based on clinical history and clinical manifestations, and later confirmed by genetic study. Caps may manifest itself in three phenotypes: FCAS (mild form), MWS (intermediate form) and Cinca (severe form). Neurological, ophthalmic, otorhinolaryngological and radiological assessments may be highly valuable in distinguishing between syndromes; 2. The genetic diagnosis with NLRP3 gene analysis must be conducted in suspected cases of Caps, i.e., individuals presenting before 20 years of age, recurrent episodes of inflammation expressed by a mild fever and urticaria; 3. Laboratory abnormalities include leukocytosis and elevated serum levels of inflammatory proteins; 4. Targeted therapies directed against interleukin-1 lead to rapid remission of symptoms in most patients. However, there are important limitations on the long-term safety. None of the three anti-IL-1β inhibitors prevents progression of bone lesions.

Tratamento térmico de normalização em tampos de vasos de pressão fabricados de material P275NH

In a market environment increasingly competitive, the companies need to control of this process accurately, avoiding rework or rejection of materials during industrialization. This can be achieved by defining procedure that assure the maintenance of the materials characteristics, as specified initially in the projects. This graduation work has the objective of defining the best heat treatment parameter of normalizing for Heads, part of a pressure vessel, formed in P275NH material. The methodology applied is based on the execution of a sequence of Heat Treatments, using different parameters. The process variables were the cooling velocity, the hold time and the hold temperature variation. As a result of this study, it is noticed that the mechanical properties of the materials are strongly influenced by the hold temperature variation and by the cooling velocity, both determined for the heat treatment cycle
