Ao paciente é necessário fornecer esclarecimentos sobre as possibilidades terapêuticas, apresentando os riscos, benefícios, prognóstico e custos de cada alternativa possível e indicada. Esta é uma determinação ética e jurídica. Não obstante, o profissional da saúde detém o conhecimento clínico/técnico/científico, e determina quais informações serão (ou não) fornecidas. O paciente decide submeter-se a um tratamento, fornecendo o seu Consentimento Livre e Esclarecido com base nos dados a ele apresentados. Infelizmente, pode ocorrer de alguns profissionais não fornecerem todas as informações necessárias a uma tomada de decisão esclarecida ou, depois de obtido o consentimento do paciente, apresentarem-lhe informação que cause sua desistência do tratamento inicialmente aceito. Esta última informação, se pertinente, e não se tratando de fato superveniente, deveria ter sido fornecida inicialmente. Porém, a informação pode não ser de todo verdadeira, e levar o paciente a decidir baseado, por exemplo, em riscos apresentados e mensurados de forma equivocada. A reabilitação crânio-facial da Articulação Têmporo-Mandibular (ATM), por meio de prótese de ATM, é indicada em muitas situações. Amiúde, pacientes que necessitam de tais próteses apresentam problemas funcionais e estéticos; a expectativa gerada com a reabilitação é grande. Este trabalho apresenta um caso e discute questões éticas e legais, incluindo a responsabilidade civil, do fornecimento parcial e inadequado de esclarecimentos a um paciente.

Objectives: 1) to evaluate the impact of oral health problems on the quality of life of pregnant women by the simplified Oral Health Impact Profile (OHIP-14) questionnaire as well by the presence of dental caries, periodontal disease and denture use/need; 2) to correlate the sociodemographic variables and the oral health conditions revealed in the clinical examinations with the OHIP-14. Method: In addition to the application of the OHIP-14 questionnaire, clinical examination of the oral conditions (CPI - community periodontal index, DMFT and prosthetic evaluation) was performed on 51 pregnant women, who sought dental treatment between April 2008 and August 2010 at the Preventive Dentistry Clinic. Descriptive analyses were made for sample characterization, bivariate analysis (chi-square or Fisher’s exact tests) and multiple logistic regressions at a 5% significance level to assess the correlation between the impact of oral health on the quality of life of pregnant women and the socio-demographic and clinical variables. Results: The OHIP-14 data showed a lesser impact of oral health on the women’s quality of life. The mean DMFT was 12.8; 70.6% of the pregnant women presented dental calculus and 58.8% needed prostheses. The association between OHIP-14 data and last dental visit and DMFT remained in the final regression model (p<0.05). Conclusion: Caries experience of the pregnant women was considered high. Most of them needed prostheses and presented dental calculus. The OHIP-14 presented a low impact on this population and was significantly influenced by the last dental visit and the DMFT index.

The purpose of this study was to evaluate the macroscopy and microstructure of a double setting alpha-tricalcium phosphate bone cement sphere provided with interconnection channels (alpha-TCP-i), as well as the integration of the implant with the rabbits' orbital tissue, through macroscopic analysis and histopathology. The external and internal surfaces of the alpha-TCP-i were evaluated macroscopically and by electron microscopy. Twelve New Zealand rabbits received 12mm implants of alpha-TCP-i following enucleation of the left eye. The clinical assessment was undertaken daily during the first 15 days, followed by fortnightly assessment until the end of the study period. For the morphological analysis, exenteration was performed in 3 animals per experimental period (15, 45, 90 and 180 days). The external and internal surfaces of the implant appeared solid, smooth and compact, with six channels which interconnected centrally. The micro-architecture was characterized by the formation of columns of hexagonal crystals. No signs of infection, exposure, dehiscence of sutures or extrusion of the implant were noted in any of the animals during the entire period of the study. The morphological evaluation demonstrated the presence of a thin capsule around the implant, from whence appeared fibro-vascular projections, which penetrated it through the interconnecting channels. In the first days after the insertion of the implant, an intense inflammatory reaction was noted. At 180 days, however, there were no signs of inflammation. The alpha-tricalcium phosphate cement implant was well tolerated in this rabbit model and appeared to be relatively inert with some fibrovascular ingrowth through the large channels.
