Oral rehabilitation of severely worn dentition using an overlay for immediate re-establishment of occlusal vertical dimension

The aim of this study was to describe the treatment used in an elderly patient presenting with bruxism and dental erosion, with good gingival health and bone support, but with decreased occlusal vertical dimension (OVD). The oral rehabilitation of elderly patients presenting with bruxism in association with tooth erosion has been a great challenge for dentists. The loss of OVD, the presence of occlusal instability and the absence of an effective anterior guide due excessive dental wear, can damage stomatognathic system (SS) biology, the function and the aesthetics. In the first treatment stage, an overlay removable partial denture (ORPD) was fabricated for the immediate re-establishment of function and aesthetics. After a 2-month follow up, with the patient presenting no symptoms, a second rehabilitation stage was accomplished, with fixed and removable prostheses. Oral rehabilitation with an ORPD was able to re-establish the SS biology, but a correct diagnosis and treatment plan are essential for success. The ORPD is a non-invasive and reversible restoring modality for general dentists that allow the re-establishment of the patient's immediate aesthetics and function at low cost.

Alteration of blue pigment in artificial iris in ocular prosthesis: Effect of paint, drying method and artificial aging

The artificial iris is the structure responsible for the dissimulation and aesthetics of ocular prosthesis. The objective of the present study was to evaluate the color stability of artificial iris of microwaveable polymerized ocular prosthesis, as a function of paint type, drying method and accelerated aging. A total of 40 discs of microwaveable polymerized acrylic resin were fabricated, and divided according to the blue paint type ( n = 5): hydrosoluble acrylic, nitrocellulose automotive, hydrosoluble gouache and oil paints. Paints where dried either at natural or at infrared light bulb method. Each specimen was constituted of one disc in colorless acrylic resin and another colored with a basic sclera pigment. Painting was performed in one surface of one of the discs. The specimens were submitted to an artificial aging chamber under ultraviolet light, during 1008 h. A reflective spectrophotometer was used to evaluate color changes. Data were evaluated by 3-way repeated-measures ANOVA and the Tukey HSD test (alpha = 0.05). All paints suffered color alteration. The oil paint presented the highest color resistance to artificial aging regardless of drying method. (C) 2010 British Contact Lens Association. Published by Elsevier Ltd. All rights reserved.

Evaluation of Patients' Perceptions of Alterations After Chin Bone Graft Harvesting

Objective: To evaluate patients' perceptions of alterations occurring after chin bone harvesting.Materials and Methods: Thirty patients were evaluated subjectively by visual analog scale-related sensitivity, facial aesthetics, eating, speaking, and lower lip movement, during 12 months. Objective analysis used the static light touch neurosensorial test. The statistical analysis was executed with Friedman test with P < 0.05 for both samples.Results: Subjective analysis revealed no alterations (1) to facial aesthetics, eating, speaking or lower lip movement but sensitivity of the mental region went from a lot of alteration initially (5) to little at the end of the study (3). Objective analysis results showed normal sensitivity (1) in the region after 12 months.Conclusion: The discrepancy between subjective and objective analyses may be indicative of the limited precision of clinical testing for subjective impressions assessment.

Da polêmica sobre a pós-modernidade aos 'desafios' lyotardianos à Filosofia da Educação

As relações entre pós-modernidade e educação tem sido objeto de inúmeras pesquisas, bem como de certa polêmica no âmbito da Filosofia da Educação, a começar pela própria conceituação da pós-modernidade até chegar às posições filosóficas engendradas por ela. em quase todas essas pesquisas e polêmicas, A condição pós-moderna, de Jean François Lyotard, se configura como uma referência importante, porém raramente as obras subseqüentes a essa são mencionadas, deixando uma parte de seu legado filosófico de fora de tais discussões e, particularmente, de suas eventuais contribuições para a educação. Tendo em vista esse limiar dos estudos sobre o assunto, o presente artigo procura desenvolver uma interpretação acerca do pensamento lyotardiano, privilegiando a análise das obras subseqüentes ao seu livro mais polêmico, com o objetivo de situar o seu projeto filosófico para além de um marco da pós-modernidade e de discutir as suas contribuições à Filosofia da Educação na atualidade. Mediante tal interpretação, recupera-se um projeto filosófico que lança alguns 'desafios' à Filosofia da Educação referentes ao deslocamento de sua problemática epistemológica para a estética, nutrida por um pensamento capaz de elucidar a face complexa e obscura da educação, a sua sombra inumana, e o diferendo constitutivo do ensino, inapreensíveis pela linguagem e pela comunicação. Assim, esperamos que tal projeto possa ser compreendido não por aquilo que traz de polêmico à Filosofia da Educação, mas pelo que a desafia no tempo presente, como uma reescrita da modernidade.

A espacialização da fala no cinema

O artigo parte de uma simples constatação: é bastante insatisfatória, no presente estágio da pesquisa, a colocação do problema das relações entre imagens e palavras no universo fílmico. Trata-se, no entanto, de uma questão decisiva para a estética do cinema. em geral, as análises feitas valorizam apenas a função das imagens na gênese e no desenvolvimento das significações. A hipótese de trabalho que se apresenta aqui, vem propor, ao contrário, uma abordagem do complexo sígnico constituído pela fusão indissolúvel dos dois recursos expressivos, que forma assim um meio de comunicação específico, original e absolutamente novo. Esse caráter inédito exige uma investigação minuciosa e urgente, conjugando-se perspectivas filosóficas, semióticas e propriamente cinematográficas.

Semiologia e pintura segundo René Passeron

Trata-se de uma síntese das principais idéias de René Passeron a propósito da fundamentação de uma análise lingüístico-semiótica das obras pictóricas. em que medida um quadro pode ser considerado um texto? Quais seriam os elementos básicos de uma pintura? Podemos falar em articulações de unidades no campo visual definido por uma obra dessa natureza? E quais os repertórios e as regras combinatórias? O artigo propõe a discussão destes problemas a partir das rigorosas e oportunas colocações do importante teórico, crítico e historiador da arte, infelizmente quase desconhecido entre nós.

Polymerization of photocurable commercial dental methacrylate-based composites - Photocalorimetry study

Due to their excellent aesthetics, photopolymers have been extensively used in several dentistry applications. However, several problems are reported, e.g. low mechanical and abrasion resistance, shrinkage during polymerization, etc. Properties of the final restorations are intrinsically related to the polymerization stage, which can be conveniently studied by photocalorimetry. In the present work the polymerization reaction and the filler content of different photocurable commercial dental methacrylate-based composites were studied by means of photocalorimetry and thermogravimetry, respectively. The results show that the values of curing rate, the heat of polymerization and the filler content vary significantly from one composite to another.

Comparing the efficacy of mandibular implant-retained overdentures and conventional dentures among elderly edentulous patients: satisfaction and quality of life

Objectives: the aim of this study was to compare the satisfaction and the quality of life in an elderly population using either mandibular conventional dentures or implant-retained overdentures.Materials and methods: A total of 34 patients were divided into two groups: group I-complete dentures users; group II - users of upper complete dentures opposed by implant-retained overdentures. The subjects were submitted to a questionnaire based on Oral Health impact Profile and oral health related quality of life to evaluate their satisfaction levels and quality of life with their prostheses. Data were evaluated using a non-parametric statistical analysis (Fischer test) with significant difference at alpha = 0.05.Results: There were no significant differences between the groups in relation to comfort, aesthetics, chewing ability, overall satisfaction, pain, functional, phonetic, social, and psychological limitations (p > 0.05). Comparing the stability of mandibular dentures, group II presented the better results (p < 0.05).Conclusion: Although the stability of the mandibular implant-retained overdenture was enhanced compared to a conventional denture, the quality of life and satisfaction levels were similar for both the groups.

Ocular Reconstruction After Zygomatic Complex Fracture With Retention of a Foreign Body

Facial injuries with the retention of foreign bodies inside the tissues, both in soft and hard ones, can cause major functional and aesthetic damage. Among the different etiological agents, cutting tools, fragments of a firearm, the splinter of wood, steel, or iron, launched by misuse, or even caused by defects in equipment, are the main cause of these injuries. The aim of this study was to discuss the peculiarity of the multidisciplinary approach in caring of a 33-year-old man, victim of an accident at work, by the rupture of an emery disc and consequent penetration of the fragments in violation of the tissues in the orbital and zygomatic region of the left side, with perforation of the eyeball and orbital-zygomatic fracture. Urgent treatment consisted of debridement of wounds, bleeding control, removal of foreign bodies, fracture reduction with rigid internal fixation, and suture, performed by the oral and maxillofacial surgical team. Reconstruction of orbital tissues by the ophthalmology team consisted of suture of the injuries. About 1 month after the trauma, phthisis bulbi was noted, and the patient underwent a new procedure under general anesthesia for eye evisceration and installation of an alloplastic prosthesis associated with the homogenous sclera. Facial harmony was restored, especially in aesthetics and function of the zygomatic-orbital complex.

O lirismo em György Lukács

The paper aims to examine the treatment of lyrical in the aesthetics work of the young Lukacs. In The Soul and the Forms the author examines the poetry of Stefan George, finding on it formal elements that point out to the emergence of a new lyricism. This "significant form" allows the author to introduce an approach of the concept of modernity, in critical and phenomenological bias. Work that will be completed in The theory of Love, when the lyric trend will be exacerbated, contaminating and altering the settings of the other genera.

Expectations and final evaluation of complete dentures by patients, dentist and dental technician

There is a poor association between the dentist's evaluation of denture quality and patients' satisfaction with their dentures. Possible differences between dental professionals and patients' expectations might help explain differences in outcome evaluations. This study compared scores given by a dentist, a dental technician and patients for their expectations before and their final evaluation after complete dentures treatment. Twenty completely edentulous patients, a prosthodontist and a dental technician provided scores for the expected aesthetic and functional results of their dentures based on a visual analogue scale at baseline. Post-treatment completion ratings were given after adjustments, by dentist and patients. The dental technician provided post-treatment completion ratings after completing the dentures. The patients had higher expectations than the dental technician and the dentist perceived for both aesthetic and function (P < 0.001). The patients also presented higher post-treatment completion ratings than the dental professionals perceived for final aesthetics (P = 0.016, Kendall's W = 0.207). and function (P = 0.002, Kendall's W = 0.303). Only the dentist presented a statistically significant difference between expectations (lower) and final (higher) outcomes for aesthetics (P = 0.017) and function (P = 0.003). There was no correlation between expectations and post-treatment completion ratings according to the patients' age. There was also no correlation between the patients' gender and expectation scores. Patients presented higher expectations regarding their dentures than dental professionals. The dentist believed that dentures would bring fewer benefits than patients did, but his perception of denture benefits post-treatment was significantly higher than his expectations.

Patients' expectations and satisfaction of complete denture therapy and correlation with locus of control

P>Considering the importance of patients' satisfaction with complete denture therapy and the influence of psychosocial aspects and expectations regarding satisfaction with their dentures, the present study aimed to test for a correlation between locus of control profiles and expectations before and satisfaction after complete denture therapy. Sixty-four patients rated their expectations for aesthetic and functional results of complete denture therapy on a 10-cm visual analogue scale (VAS), using scores from 0 (worst results) to 10 (best results). A similar questionnaire was used regarding satisfaction after final denture adjustments. Patients also answered a locus of control questionnaire in the initial interview. anova and a chi-squared test were used to test for correlations among ratings, patient gender and locus of control profiles. The significance level adopted was 0 center dot 05. The expectation ratings before treatment were significantly lower than the post-treatment completion ratings, both for aesthetics (P < 0 center dot 001) and function (P = 0 center dot 004). There was no correlation between locus of control profiles and patients' ratings or between gender and VAS scores. No correlation was found between locus of control profiles and scores for expectations before and satisfaction after complete dentures.

Aesthetic and functional ocular rehabilitation

The ocular losses are embarrassing to the bearer because they commit the face which has the essential organs for the human relationship. The present study shows the multidiscipline interaction in the treatment of a child who lost his left eye victim of a fire gun and needed an ocular plastic surgery for a correct prosthesis insertion. The ocular prosthesis fills in the ocular cavity simulating the facial growth and restoring its symmetry. Therefore, there are aesthetics, anatomic and physiological improvement on the child's face that allows her to be reinstated in society without being discriminated for her differences. © 2005 Elsevier Ltd.
