Avaliação do serviço odontológico de autogestão da Fundação de Amparo Social do Hospital Moinhos de Vento

Propósito: Avaliar os impactos econômicos e assistenciais de duas estratégias de redução de custos em um plano odontológico de autogestão. Métodos: O presente estudo avaliou a assistência odontológica fornecida a cerca de 4000 usuários de uma empresa. A análise foi dividida em três momentos: 1) linha de base (controle): quando assistência odontológica fornecida aos funcionários era terceirizada por uma empresa que operava com rede credenciada, 2) quando houve uma renegociação de preços com a prestadora original e 3) quando a assistência era feita por um serviço de odontologia próprio sem a intermediação de uma prestadora e com profissionais remunerados através de valores fixos. Foram coletados dados econômicos e sobre o tipo e número de procedimentos realizados. Os dados econômicos foram ajustados para inflação através do índice nacional de preços ao consumidor – ampliado (IPCA). Resultados: A renegociação de preços reduziu os custos em cerca de 37% em relação a linha de base ao passo que o serviço próprio reduziu os custos em 50% . A renegociação de preços provocou uma diminuição de 31% no número de procedimentos realizados sem modificar o perfil da assistência, ao passo que o serviço próprio não causou diminuição na quantidade de serviços, mas modificou o padrão da assistência, onde aumentaram os procedimentos relacionados com as causas das patologias e reduziram-se os procedimentos cirúrgico-restauradores. Conclusão: Entre as duas estratégias de redução de custo, o serviço próprio com protocolos clínicos embasados em evidência atingiu um melhor resultado, pois atingiu uma maior redução de custos, não reduziu os benefícios, mudou o paradigma de atendimento para um perfil de promoção de saúde, ampliou a cobertura e melhorou a satisfação do usuário.

Saúde bucal no programa de saude da família: o caso do distrito sanitário norte em Natal - RN

The inclusion of the dentist in the Family Health Program (FHP) teams designates a reorganization of the mouth health care in your country and establishes a new scenario in Brazilian odontology, through of a new way to organize the basic health care, creating conditions to consolidate in mouth health practice actions, in the level of the basic attention, the validation of Unique Health System (UHS) constitutional principles. The purpose of this research is to verify if the actuation of mouth health teams (MHT) dentists, in Natal city north sanitary district, is tuned with FHP goals.The target research population was composed by all dentists working in Basic Health Units (BHU) of Natal north sanitary district. Fifth-eight questionnaires were applied and using open and closed questions we look for identify the functional characteristics of each BHU, the dentists professional attributions on each BHU, as well as the clinical procedures that they execute. This research also searched to identify the factors that facilitate and/or difficult the inclusion process and the dentists activities performance on these BHUs, as well as the necessary actions to north sanitary district MHTs to fulfill the objectives proposed by FHP. The results point that the inclusion of mouth health actions in north sanitary district FHPs brought the incorporation of new values to the used practices. Whoever, its necessary a more frequent evaluation of the carried actions, in a way they can be adapted to the real community necessities, and, is fundamental the data accompaniment, for that these serve of base for planning and redirecting activities, in a way that we do not have only a reproduction of traditional practices, fragmented and isolated, but a truly substitution of the traditional practices and a new way of promoting health

Estudo de sistemas vítreos para infiltração em alumina

The system in-Ceram Alumina, produced by VITA, consists in a technique of prepare of a substructure of ceramics to dental crowns. First burning is made in the alumina decanted by slip casting process under a stone die that reproduces the tooth prepared to receive a crown. In a second burning, alumina is infiltrated by vitreous system, giving to this set a high mechanic resistance. In this work, it s made a study of the composition of a new infiltrating material more used nowadays, giving to alumina desirable mechanics proprieties to its using like substructure of support to ceramic s crown used in the market today. The addition of Lanthanum oxide (frit A) and calcium oxide (frit B) was made in attempt to increase the viscosity of LZSA and to reduce fusion temperature. The frits were put over samples of alumina and took to the tubular oven to 1400ºC under vacuum for two groups (groups 1 and 2). For another two groups (groups 3 and 4) it was made a second infiltration, following the same parameters of the first. A fifth group was utilized like group of control where the samples of pure alumina were not submitted to any infiltrating process. Glasses manifested efficient both in quality and results of analysis of mechanic resistance, being perfectly compatible with oral environment in this technical requisite. The groups that made a second infiltration had he best results of fracture toughness, qualify the use in the oral cavity in this technical question. The average of results achieved for mechanic resistance to groups 1, 2, 3, 4 and 5 were respectively 98 MPa, 90 MPa, 144 MPa, 236 MPa and 23 MPa

Estudo da zircônia reforçado com alumina

Ceramics materials have good properties including chemical stability, high hardness and wear resistance. Moreover, due to its fragility, can suffer failure under relatively low levels of tension. Actually zirconia is the material of choice in metal free dental prostheses used in dentistry due its inertia in physiological environment, good bending strength, hardness and fracture toughness. The alumina and mixed tungsten and titanium carbides additions, acting as reinforcement elements in the zirconia matrix, have as their main objective the improvement of mechanical properties of this material. In this work, samples of zirconia, zirconia with 30% wt of alumina and zirconia with 30% wt mixed carbides were analyzed. The samples were sintered by uniaxial hot pressing on 30 MPa pressure, for 1 hour in an argon atmosphere. They were physically characterized by porosity and density measurements, and mechanically by 3-points bending strength and Vickers microhardness. The X-ray diffraction was used for the phase identifications and microstructure was examined by scanning electron microscopy (SEM). The addition of mixed carbides as reinforcement elements in zirconia matrix provides improvements in all properties analyzed in this work. The alumina addition has dropped the zirconia strength, although it caused improvement in other properties

Análise mecânica e microestrutural das ligas de cobalto-cromo de uso odontológico após sucessivas refundições

The cobalt-chromium alloy is extensively used in the Odontology for the confection of metallic scaffolding in partial removable denture. During the last few years, it has been reported an increasing number of premature imperfections, with a few months of prosthesis use. The manufacture of these components is made in prosthetic laboratories and normally involves recasting, using parts of casting alloy and parts of virgin alloy. Therefore, the objective of the present study was to analyze the mechanical properties of a commercial cobalt-chromium alloy of odontological use after successive recasting, searching information to guide the dental prosthesis laboratories in the correct manipulation of the cobalt-chromium alloy in the process of casting and the possible limits of recasting in the mechanical properties of this material. Seven sample groups were confectioned, each one containing five test bodies, divided in the following way: G1: casting only with virgin alloy; G2: casting with 50% of the alloy of the G1 + 50% of virgin alloy; G3: casting with 50% of the alloy of the G2 + 50% of virgin alloy; G4: casting with 50% of the alloy of the G3 + 50% of virgin alloy; G5: 50% of alloy of the G4 + 50% of virgin alloy; G6: 50% of alloy of the G5 + 50% of virgin alloy and finally the G7, only with recasting alloy. The modifications in the mechanical behavior of the alloy were evaluated. Moreover, it was carried the micro structural characterization of the material by optic and electronic scanning microscopy, and X ray diffraction.and fluorescence looking into the correlatation of the mechanical alterations with structural modifications of the material caused by successive recasting process. Generally the results showed alterations in the fracture energy of the alloy after successive recasting, resulting mainly of the increasing presence of pores and large voids, characteristic of the casting material. Thus, the interpretation of the results showed that the material did not reveal significant differences with respect to the tensile strength or elastic limit, as a function of successive recasting. The elastic modulus increased from the third recasting cycle on, indicating that the material can be recast only twice. The fracture energy of the material decreased, as the number of recasting cycles increased. With respect to the microhardness, the statistical analyses showedno significant differences. Electronic scanning microscopy revealed the presence of imperfections and defects, resulting of the recasting process. X ray diffraction and fluorescence did not show alterations in the composition of the alloy or the formation of crystalline phases between the analyzed groups. The optical micrographs showed an increasing number of voids and porosity as the material was recast. Therefore, the general conclusion of this study is that the successive recasting of of Co-Cr alloys affects the mechanical properties of the material, consequently leading to the failure of the prosthetic work. Based on the results, the best recommendadition is that the use of the material should be limited to two recasting cycles

Estudo da viabilidade do processo de reciclagem do material descartado do sistema Zirkonzanh® de produção de próteses dentárias

At present, the material of choice for performing aesthetic dental prosthetic work is in the ceramic. Among them, the ceramic base of stabilized zirconia with 3% yttria (3Y - TZP) stand out for having excellent physical and mechanical properties. During the machining of blocks of zirconia in the laboratory to prepare the various types of prostheses, much of the material is given off in the form of powder, which is subsequently discarded. The waste of this material results in financial loss, reflecting higher final cost treatment for patients, as well as damage to the environment, thanks to the processes involved in the manufacture and disposal of the ceramic. This research, pioneered the recycling of zirconium oxide powder obtained during milling of dental crowns and bridges, we highlight the social and environmental aspects and aims to establish a protocol for the reuse of waste (powder of zirconia Zirkonzahn® system) discarded to obtain a new block of compacted zirconia to maintain the same mechanical and microstructural properties of commercial high-cost imported material. To compare with the commercial material, samples were uniaxially (20 MPa) and isostatically (100 MPa), and its mechanical and microstructural characterization was performed through tests of density, porosity, dilatometry, X-ray diffraction (XRD), hardness, fracture toughness, resistance to fracture electron microscopy (SEM) and analysis of grain size. The results observed in the samples were isostatically pressed similiares those obtained with samples from the commercial material demonstrating the viability of the process

Associação entre as narrativas em saúde bucal e condições socioeconômico-culturais: a dentição como reflexo da desigualdade social

This anthropological study investigates the lived-experience of oral diseases in the context of poverty in Northeast Brazil. During six months in 2004???, ethnographic interviews, narratives and participant-observation with 31 residents of the low-income community, Dendê, located in Fortaleza, Ceará were conducted and analyzed utilizing a hermeneutic-dialetic method. It is revealed that precarious life conditions make prioritizing caretaking a difficult task. Despite suffering tooth pain, seeking a dentist's care is perceived as "a luxury" not a citzens' right. Difficulties in accessing services and poor quality restorations, favor tooth extractions as the most effective intervention. The deterioration of one's oral health is lamented by community members who seek help from popular clinics, politicians and traditional healers. The experience of dental disease differs according to social class, leaves oral scars of inequity, harms self-esteem and inhibits social inclusion. In this context, "treating" the Teeth of Inequity demands that we deepen our comprehension of the social determinants of health, reduce injustice in the access to quality care, remove demoralizing stigmas and empower the community to confront structural forces which affect its life
