Parafunção severa: reabilitação oral com prótese total mandibular x overlay maxilar: relato de caso

In many oral rehabilitation professionals seeking venture renew people smile. However, these procedures have functional implications and aesthetic criteria which must be satisfied so that the final result is predictable. The restoration of relations intermaxillary, phonetics, masticatory function, esthetics and patient comfort are the goals to be achieved. An effective way to achieve these goals when immediate reconstruction with permanent dentures is not possible, make use of a type of partial denture called overlay. Bruxism is a manifestation of biopsychological imbalance that affects the stomatognathic system, characterized by clenching and / or attrition of teeth together so centric or eccentric, can be manifestation of nocturnal or diurnal. Its effects can manifest themselves in different parts of the stomatognathic system, varying the severity of the damage as the resistance of the structures affected, the time of existence, its regularity and the general state of the wearer. The description of the steps followed in solving this case, in which the patient edentulous mandibular arch while the maxillary arch showed absence of teeth 16 and 26 and, except for the teeth 17 and 27, all other teeth showed wear very sharp in the sense denoting incisal cervical, severe impairment of the vertical dimension, the quality of masticatory function and a marked impairment phonetic, this case report aims to guide the beginning of a rehabilitation, as well as the transitional phase of treatment for recovery of functional and aesthetic relationships intermaxillary .

Corrosion resistance of Ni-Cr alloys in different mouthwashes

Several alloys have been used for prosthodontics restorations in the last years. These alloys have a number of metals that include gold, palladium, silver, nickel, cobalt, chromium and titanium and they are used in oral cavity undergo several corrosion. Corrosion can lead to poor esthetics, compromise of physical properties, or increased biological irritation. The objective of this study was evaluated corrosion resistance of two alloys Ni-Cr and Ni-Cr-Ti in three types of mouthwashes with different active ingredients: 0.5g/l cetylpyridinium chloride + 0.05% sodium fluoride, 0.05% sodium fluoride + 0.03% triclosan (with fluor) and 0.12% chlorohexidine digluconate. The potentiodynamic curves were performed by means of an EG&G PAR 283 potentiostat/galvanostat. The counter electrode was a platinum wire and reference electrode was an Ag/AgCl, KCl saturated. Before each experiment, working electrodes were mechanically polished with 600 and 1200 grade papers, rinsed with distilled water and dried in air. All experiments were carried out at 37.0oC in conventional three-compartment double wall glass cell containing mouthwashes. The microstructures of two alloys were observed in optical microscopy. Analysis of curves showed that Ni-Cr alloy was less reactive in the presence of 0.12% chlorohexidine digluconate while Ni-Cr-Ti alloy was more sensitive for others two types of mouthwashes (0.5g/l cetylpyridinium chloride + 0.05% sodium fluoride  and 0.05% sodium fluoride + 0.03% triclosan). This occurred probably due presence of titanium in this alloy. Microstructural analysis reveals the presence of dendritic and eutectic microstructures for NiCr and Ni-Cr-Ti, respectively.

Tratamento de superfície de implantes dentários: SBF

Various surface treatments of dental implants have been developed in order to ensure anchorage to bone tissue, optimization of the determinants of electronic structure, crystallinity, composition and properties. Coating techniques have been proposed in order tocreate unionbiochemicalable to accelerate the early stages ofbone tissue, combining the positive properties of titanium and its alloys bioactivity of ceramic materials. This paper discusses protocol for handling the SBF coating of titanium alloys. The apatite phase nucleation occurs by immersing the substrate in synthetic solution simulating blood plasma (Simulated Body Fluid). The protocol allows manipulation of the SBF solution to establish guidelines regarding the usestreamlinedand organized to make practical application.

The influence of the alveolar ridge shape on the stress distribution in a free-end saddle removable partial denture supported by implant

The alveolar ridge shape plays an important role in predicting the demand on the support tooth and alveolar bone in the removable partial denture (RPD) treatment. However, these data are unclear when the RPD is associated with implants. This study evaluated the influence of the alveolar ridge shape on the stress distribution of a free-end saddle RPD partially supported by implant using 2-dimensioanl finite element analysis (FEA). Four mathematical models (M) of a mandibular hemiarch simulating various alveolar ridge shapes (1-distal desceding, 2- concave, 3-horizontal and 4-distal ascending) were built. Tooth 33 was placed as the abutment. Two RPDs, one supported by tooth and fibromucosa (MB) and other one supported by tooth and implant (MC) were simulated. MA was the control (no RPD). The load (50N) were applied simultaneously on each cusp. Appropriate boundary conditions were assigned on the border of alveolar bone. Ansys 10.0 software was used to calculate the stress fields and the von Mises equivalent stress criteria (σvM) was applied to analyze the results. The distal ascending shape showed the highest σvM for cortical and medullar bone. The alveolar ridge shape had little effect on changing the σvM based on the same prosthesis, mainly around the abutment tooth.

A música associada às necessidades terapêuticas de pacientes com deficiência

The use of music and/or its elements (instruments, sound, rhythm, melody and harmony) in environments with people attended by public health centers, aims at promoting communication, facilitating the expression and the relationship in the first contact, hence favoring organization of standards and other relevant therapeutic objectives to assist physical, mental, social and cognitive needs of people, thus promoting the process of environmental adaptation, behavioral conditioning and social inclusion. The purpose of this project is to use music and its sound elements, as well as recreational activities, developed in stages called: socialization session, art workshop and complementary activities, with patients assisted at CAOE (Disabled People Dental Care Center) and their relatives. The objective is to provide them psychological wellbeing, inclusion to physical space, relaxation, stimulation of rhythmic and sonorous perceptions, memorization, emotions externalization, help and encouragement for the development of motor coordination during their daily activities of daily. Recreational activities, handling and contacting with musical instruments, broadcasting and producing sounds, stimulate cognitive capacity, interactivity and entertainment activities can greatly contribute to improve the behavioral reaction and adaptation of these patients, during their dental treatment.

A experiência da saúde coletiva na formação profissional: retrato da extensão universitária

The guidelines of National Curriculum for Dental courses highlights the necessity in providing for the professional the ability to analyze and assess community’s problems and needs, and to create solutions for the society. The continuing education may be considered a useful tool for the teaching and learning because it favors the diversification of learning environments, which allows the insertion of undergraduate and graduate students into the real scenarios. This current study aimed to assess the Public Health projects and programs of the UNESP – Araçatuba Dental School, by describing the interaction experiences between faculty and health services in the professional career development. Historical, documentary and descriptive searches were performed based on the faculty archives such as official documents, reports, databases from the Pro-rector of continuing education and published papers in the period between 1964 and 2011. The following experiences were noted: the Extra-Muro Dental Service (SEMO), established in 1964, that focused in providing dental treatment to the rural population, highlighted the social inclusion of discriminated society groups since that time. In 1972, this service was expanded to several specific populations living in the urban areas. In the '60s, many educational campaigns were performed as homemade water filter and construction of wells and septic tanks which demonstrate the concern with the determinants of healthdisease process. At that time, the campaign of fluoridation of public water supplies in several counties started as Araçatuba, Birigui, Penápolis, Guararapes, Valparaíso and so on. The Campaign of “Good Teeth” from the '70s became wider over time and it was transformed in the "Oral Health Education Program" and it was continuously developed in all public schools of Araçatuba and some neighboring towns, benefiting children aged from 6 to 10 years-old. Several epidemiological studies of caries, periodontal diseases, malocclusion and fluorosis were conducted in cooperation with local governments, and counted with the participation of undergraduate and graduate students. Pereira Barreto – SP was the precursor city in Brazil to carry out fluorosis study. Currently, 12 projects of Public Health from the Institution of Higher Education in the Pro-rector of continuing education are being developed. The concern in qualifying the human resources in health is confirmed with the development of training courses and workshops for professionals, highlighting the training for people enrolled in the Family Health program; Community Health Agent training - Solidarity University, and Municipal Health Counselors training. The Graduate Program in Social and Preventive Dentistry, created in 1993, has an important role to train several professionals for the Unified Health System, and provides education to create researchers, professors and administrators, and enucleates research groups in several Brazilian states. In all activities showed herein, a dynamic participation of undergraduate and graduate students has been observed, and several books, guidelines, articles, brochures and booklets have been published as a result of the continuing education activities.. It was concluded that different projects and programs have been developed by the Public Health of UNESP –Araçatuba Dental School, which allow the exchange of experience between the university and health services, and benefit all participants enrolled in these activities.

Percepção de acadêmicos de odontologia sobre o envelhecimento

The changes on learning space where Dentistry Students stay in front of social reality, by university extension, represent a strategy to form dentists according to Brazilian Curricular Directresses. In Araçatuba Dental School (FOA-UNESP), one of alternatives to add students on real locals of dentistry practices is the “Always Smiling Project – Dental Attention for institutionalized elderly in Araçatuba City, São Paulo State – Brazil”. The aim of this study was to verify the self-perception of dentistry students about aging before and after participation in this Project during one school year. To data collection, an instrument with 3 opened questions was performed and applied on 45 students, in the beginning of activities in 2009 and after 8 months. The answers were analyzed by content categorization. The results showed that the perception of students about old people was negative relating them with frail person that needs help and the students’ expectations were higher about clinical aspects of attention. In the end of school year was clear the difference of students’ comprehension about aging and their thoughts demonstrated the empathy resulting from relation. Besides, students related knowledge gain and noted that health attention involve others aspects that are over than biological space. It was possible to conclude that insertion of students in “Always Smiling” contributed to reflection and learn about aging process and suggest that practices like these should be added in Brazilian Universities.
