Alternativa de tratamento simplificado e integrado da retenção intraóssea de incisivo central superior, associada a odontoma: relato de caso

Permanent teeth impaction is highly prevalent among brazilian people. Its etiology is related to local and general factors association. Permanent teeth retention compromises dental occlusion and when anterior teeth are involved, it also brings esthetics impairments which lead to psychological disturbance. Early diagnosis and adequate treatment are extremely important to solve not only occlusal problems but also psychological aspects. Orthodontic traction of impacted teeth can be conducted by using fixed or removable appliances. Although it depends on patient compliance the use of removable appliances provides an anchorage based on the teeth and the palate reducing undesirable side effects. This paper describes the case of a fourteen years old female patient whose right maxillary central incisor was adequately tractioned with a removable orthodontic appliance. Removable orthodontic devices were used at first to reposition teeth in maxillary anterior area what provided adequate space to allow the placement of the impacted incisor and after were also used to traction and position this tooth. The procedure described seemed to be effective, non expensive and a viable treatment to be performed even on the scope of public health services, extending orthodontic treatment to a higher number of patients.

Variação sazonal das variáveis físicas e químicas em riachos de duas bacias da região centro-sul do estado do Paraná, sul do Brasil

The present study was developed in two streams from the two different drainage basins located in the mid-southern region of Paraná state. In each stream were evaluated some physical and chemical parameters in open (without streamside vegetation) and shaded (with streamside vegetation) segments. Monthly samplings were carried out from January to December 2007. The following limnological parameters were measured: water temperature, specific conductance, oxygen saturation, pH, turbidity and current velocity. In the same stream were not observed differences among segments from the drainage basins, and nominal values and seasonal pattern have been very similar between open and shaded ambient. A Principal Component Analysis (PCA) showed small divergence between streams and segments, with separation of groups with base sampling dates. The results suggest that the region is homogeneous according to physical and chemical water conditions, therefore, stronger influenced for time factor, and diverging seasonal periods associated a climatic region condition.

Estudo comparativo de parâmetros limnológicos de duas bacias de drenagem da região centro-sul do Estado do Paraná, sul do Brasil

Two drainage basins located in the mid-southern region of Paraná state were comparatively studied for analysis of limnological characteristics in lotic ecosystems. Ten segments of rivers and streams were evaluated in each basin, from June 4th through to June, 29th , 2007. The following physical and chemical parameters were measured: water temperature, specific conductance, oxygen saturation, pH, turbidity, current velocity and depth. The two drainage basins presented similar nominal values for all parameters investigated. There were significant differences between the two environments in relation to temperature, pH, and oxygen saturation. Cluster analysis revealed five small groups of samplings, each one with particular limnological characteristics. The Principal Components Analysis (PCA) confirmed the difference among the drainage basins. These results suggest an influence of regional and local factors in limnological characteristics of rivers and streams in the studied drainage basins.

Sistemas de retenção O'ring e barra-clipe em overdenture mandibular

The dissatisfaction of the treatment with mandibular complete dentures in edentulous patients has been a constant problem in Dentistry. Often, the absence of stability and retention, resultants of a physiologic condition and alveolar ridge resorption, bring reduction of chewing force, speech problems and social life interference. In these cases, the rehabilitation over osseointegrated implants can be an effective and safe alternative of treatment. When it is not possible to put implants in appropriate number and disposition, it is necessary to make a simple and low costing prosthetic planning, which makes resurge the overdentures. Various implant supported attachment systems for overdentures have been developed in the dental market. Thus, intending to facilitate the professional choice, this study review the literature about attachment systems O’ring and bar- clip in its following aspect: retention level, stress distribution, hygiene complications and patient satisfaction.

Uso de sistema de retenção magnético como opção de tratamento para solução de caso com espaço interoclusal reduzido

The treatment with overdenture supported by tooth consists in complete or partial removable prosthesis confection in which some satisfactory tooth are maintained and used to aiding retention associated with any retention system. The purpose of this case report is to show the use of magnet attachment in the confection overdenture to improve the oral rehabilitation in cases with restricted intermaxillary space. The treatment was considered successful by the patient and no need for excessive alteration in the prosthesis was required in the follow-up period of 6 months.

Comportamento biomecânico dos sistemas de retenção de overdentures

Objective: to the purpose of this study was to compare the stress distribution in the peri-implant hard tissue on different attachment systems for mandibular or maxillary implant-retained overdentures. Material and methods: the search for published studies was performed on PubMed/Medline database covering the period of January 2000 to April 2014. The selection of the eligible studies was performed according to including and excluding criteria. Results: a total of 140 studies were screened and according to the search strategy, 21 studies were selected for this review. Eight studies perfomed strain-gauge analysis, 5 evaluated the stress distribution though photoelastic test and 7 performed tridimensional finite element analysis. Only one study in vivo was included. Non-splinted O-rings showed better stress distribution than other bar-clip attachment systems. Conclusions: the present study did not find sufficient evidences regarding the most indicated attachment system for overdentures with better stress distribution for the peri-implant hard tissue. The methodologies analyzed should be complemented with other tests and used as a tool for further clinical studies.

Sistemas de retenção intrarradicular: considerações teóricas e comportamento biomecânico

The aim of this study was to review the current scientific literature to discuss the biomechanical behavior and characteristics inherent to both cast post and core and the prefabricated posts used in the practice of restoring endodontically treated teeth. To identify studies of this review, it was performed a detailed and advanced search strategy to the databases PubMed and Medline. It was used as descriptors: endodontically treated teeth, post, core, fiber post and metal post. Inclusion criteria were: clinical trials, randomized controlled trials, in vitro studies, literature reviews and systematic reviews with or without meta-analysis of the last 10 years that addressed the theme. Exclusion criteria were: articles without abstracts, animal studies, articles whose language was not English and articles from journals that do not belong to the Dentistry field. Of a total of 35 articles, after an analysis according to inclusion and exclusion criteria, 23 articles were selected. Most of the current scientific literature indicates that the prefabricated fiber reinforced and ceramic posts should be appointed for endodontically treated teeth that have a minimum height of 2mm ferrule. As for the cast metal cores, along with pre-fabricated metal represent a good prosthetic option, when weakened teeth have to be restored for any reason. Despite the large number of studies, there is still a lack of longterm prospective studies that evaluate the effectiveness of these posts in the treatment of endodontically treated teeth.

Promoção e avaliação da atitude de Vigilância Nutricional na Atenção Básica à Saúde de municípios das bacias Piracicaba-Capivari

Considering the importance of food and nutritional surveillance as part of a community's basic health care, our objective was to expose and discuss the educational experience of eleven municipalities of the state of São Paulo geared to build an attitude of nutritional security. The accounts were made in the form of workshops with the contribution of basic health care workers of each municipality, based on daily field worksheets and followed by an evaluation process, which used a semi-structured questionnaire. The results were classified into four categories. The methodology, based on the actual participation in the workshops was considered adequate, although some exposure and removal of personal inhibitions were necessary. These barriers were left behind with the aid of group dynamic exercises. Among the themes treated, anthropometry was highlighted because of insufficient technical know-how and standardization. An attitude towards nutritional surveillance was recognized by the health-care professionals as an important basis for the nutritional practice in order to attain food and nutritional security.
