Percepção estética e funcional de pacientes submetidos à cirurgia ortognática / Functional and aesthetic perception of patients that undergone orthognathic surgery

As deformidades dentofaciais promovem implicações funcionais e estéticas variáveis em função da percepção dos pacientes. De modo semelhante, o tratamento orto-cirúrgico promove mudanças na condição do complexo maxilomandibular e facial, com melhorias naqueles aspectos. Assim, o objetivo deste estudo foi compreender a percepção estética e funcional relacionadas aos pacientes submetidos à cirurgia ortognática por motivos ortodônticos não relacionados ao trauma, analisando as implicações psicossociais atreladas à sua condição clínica pregressa e atual. Adotou-se um delineamento metodológico em que vinte pacientes que já se submeteram à cirurgia ortognática foram questionados quanto à dificuldade em desempenhar oito atividades diárias, em ambos os momentos pré e pós-cirúrgico. Utilizou-se o índice IODD (Impacto Oral no Desempenho Diário) como instrumento de pesquisa. A análise dos resultados revelou que, na fase pré-cirúrgica, 85% dos participantes referiram impacto em alguma atividade diária, sendo que as dificuldades mais relatadas nas atividades funcionais foram justificadas por dor, desconforto ou limitação na função. Já na fase pós-cirúrgica, 55% dos indivíduos relataram algum impacto nas atividades diárias, o que denota uma percepção positiva quanto à satisfação dos resultados da cirurgia. No geral, os dados foram conclusivos ao mostrar a influência da condição bucal na qualidade de vida dos participantes com aspectos que transcendem o plano funcional e envolvem a dimensão psicossocial. A cirurgia ortognática, por sua vez, permitiu uma melhoria funcional e estética com repercussão nas relações pessoais e sociais (AU)

Dentofacial deformities promote functional and aesthetic implications that vary according to patients' perception. Similarly, the orthosurgical treatment causes changes in the maxillomandibular and facial complex condition, with improvements in those aspects. Thus, the aim of this study was to understand the functional and aesthetic perceptions related to patients who had undergone orthognathic surgery for orthodontic reasons not related to trauma, analyzing psychosocial implications linked to their past and present condition. It was adopted a methodological design in which twenty patients who had undergone orthognathic surgery were asked about the difficulty of performing eight daily activities, pre and post-surgery. The OIDP (Oral Impact on Daily Performance) index was used as a research tool. The results analysis showed that during the presurgical phase 85% of participants reported some impact on daily activity, the most reported difficulties in functional activities were justified by pain, discomfort or limitation in function. In the post-surgical phase, 55% individuals reported having some impact on daily activities, which indicates a positive perception about surgery results satisfaction. Overall, data were conclusive showing the influence of oral conditions in the par-ticipant's life quality with aspects that transcend the functional level and involve the psychosocial dimension. Orthognathic surgery, in turn, allowed a functional and aesthetic improvement having effects on the personal and social relationships. (AU)

Efeito da técnica de polimento na topografia de superfície e na transmitância da resina composta / Effect of polishing technique on the surface topography and transmittance of the composite resin

Introdução: Clinicamente, é comum observar os efeitos de estratificação de restaurações de compósito apenas após o polimento. Objetivo: Avaliar o efeito da técnica de polimento na transmitância de luz e na topografia de superfície de uma resina composta. Material e método: Amostras da resina Filtek Z-350 XT (cor A1E) foram confeccionadas em matriz metálica. Uma das superfícies das amostras recebeu acabamento com brocas de 12 lâminas e polimento através de uma das seguintes técnicas: SL (Sof-Lex), EH (Enhance) e DH (DHPro). Ausência de polimento foi usada como controle. Após o polimento, as amostras deviam apresentar espessura final de 1 mm. A transmitância de luz foi avaliada através do espectrofotômetro, sendo considerada apenas a luz no espectro visível. A topografia de superfície foi avaliada através de interferometria a laser, com os parâmetros Sdq (híbrido), St (amplitude máxima) e As (média de picos e vales). Os dados (n=5) foram submetidos a ANOVA e teste SNK. O teste de correlação de Pearson correlacionou Sdq, St e Sa à transmitância (α=0,05). Resultado: Todos os sistemas de polimento aumentaram a transmitância de luz em relação ao controle, não havendo diferença entre estes. Apenas as amostras polidas com SL e DH apresentaram maiores valores de Sdq que o Controle. Já para os parâmetros St e Sa, EH mostrou menores valores que o controle. Sdq e St mostraram correlação significativa com transmitância. Conclusão: Todos os sistemas de polimento foram efetivos em aumentar a transmitância, sendo a redução dos valores Sdq e St relacionada a esta modificação. .

Introduction: Clinically, it is common to observe the effects of composite restorations stratification only after the polishing. Aim: This study evaluated the effect of polishing technique on light transmittance and surface topography of a composite resin. Material and method: Specimens of the composite resin Filtek Z-350 XT (color A1E) were built-up using a metal matrix. One of the specimens surfaces was finished with 12-blade burs and polished using one of following techniques: SL (Sof-Lex), EH (Enhance) and DH (DHPro). No polishing was used as control. After the polishing procedures, the samples were measured to check the final thickness (1 mm). The light transmittance was measured using a spectrophotometer connected to an integrating sphere, considered only light in the visible spectrum. The surface topography was measured by laser interferometer, assessing the parameters Sdq (hybrid), St (maximum amplitude) and Sa (average of peaks and valleys). Data (n=5) were submitted to ANOVA and SNK's test, while Pearson's correlation test was used to related Ssq, St and Sa to transmittance (α=0,05). Result: All polishing systems increased the light transmittance when compared to control, whereas no difference was observed between them. Only the samples polished with SL and DH showed lower Sdq values than control. Although for St and Sa parameters, EH showed lower values than those observed for control. Sdq and St showed significant correlation with transmittance. Conclusion: All polishing systems were effective to increase the transmittance, while the reduction of Sdq and St values were related to this modification. .

Conservative esthetic treatment of a discoloured calcified permanent tooth: five-year clinical evaluation / Tratamento conservador estético de um dente permanente calcificado e escurecido: cinco anos de acompanhamento clínico

Objective: Pulp calcification can compromise tooth color and negatively affect esthetics. Definitive treatment for discolored anterior teeth with calcification is usually provided by endodontic treatment with the use of internal and external bleaching agents, as necessary. This article presents the conservative management of a vital tooth with an obliterated pulp chamber that led to changes in tooth color. The benefits and limitations of the use of in-office and home supervised bleaching techniques are discussed

Objetivo: Uma calcificação pulpar pode comprometer a cor dos dentes e afetar negativamente a estética dental. O tratamento de escolha para um dente anterior escurecido e com calcificação pulpar é geralmente o tratamento endodôntico seguido de clareamento interno e externo, se necessário. Esse artigo relata um caso clínico de um tratamento conservador de um dente vital com câmera pulpar obliterada que ocasionou alteração de cor do elemento dental. Os benefícios e as limitações do uso das diferentes técnicas de clareamento dental utilizadas também foram discutidos.

A Descriptive Epidemiology Study of Oral Cleft in Sergipe, Brazil

The nonsyndromic orofacial cleft is the fourth most common birth defect, but in Brazil, data about the cleft epidemiology are not accurate. Objective: This study aimed to describe the epidemiologic characteristics of oral cleft cases at Specialized Society Attending Cleft Patient in Sergipe State. Methods  Data were obtained from patients' medical records in relation to the following characteristics: age; gender; race; origin; cleft type; additional malformations and/or complications; prenatal accomplishment; treatment applied. For diagnosis analysis, it was noted if mothers had received prenatal care and if they had ultrasonography performed and if the cleft was viewed in it. Results: We observed a prevalence of male gender (54%). Age between 0 and 4 years old was most prevalent (53%), and pheoderma race was observed in 47%. Transincisive foramen cleft was found in 52.3% of the individuals. The prevalence of pre- and transincisive foramen cleft was higher in men (66.3 and 55.7%), women accounted for 65.0% of postincisive foramen, and atypical facial cleft (0.3%) occurred in one case. Associated malformations and complications were present in 12% of patients. Prenatal care was reported by 48% of the mothers. Conclusion: In this study male gender was the most affected, and 0 to 4 years was the most frequent age group. Transincisive foramen cleft type was most frequently encountered. Prenatal care was reported by most mothers. So, this study found that early treatment is a reality in SEAFESE (Service Specializing in Cleft Care of Sergipe), and consequently the chances of successful integration of the child to society will be better...
