Functional recovery time after facial fractures: characteristics and associated factors in a sample of patients from southern Brazil.

Understanding the cause, severity, and elapsed time for the restoration of the functions of maxillofacial injuries can contribute to the establishment of clinical priorities aiming at effective treatment and further prevention of facial trauma. The objective of this study was to understand the factors associated with the restoration of mastication, ocular, and nasal functions in the face of trauma victims, estimating their recovery time after surgical treatment. We analyzed 114 medical records of patients treated at the Hospital Montenegro, who attended follow-up consultations for up to 180 days. For analysis of the recovery time, we performed survival analysis, followed by COX analysis. We observed that half of the patients recovered their functions within 20 days. The average time for recovery from trauma in the zygomatic-orbital-malar-nasal complex was 11 days, and in the maxillary-mandibular complex, 21 days (HR: 1.5 [0.99 2.3], p = 0.055). Although functional reestablishment has reached high rates after the surgical approach, it is necessary to analyze the failing cases, as well as the economic impacts and the prevention strategies associated with facial trauma, to improve the service to the population.

ABSTRACT Understanding the cause, severity, and elapsed time for the restoration of the functions of maxillofacial injuries can contribute to the establishment of clinical priorities aiming at effective treatment and further prevention of facial trauma. The objective of this study was to understand the factors associated with the restoration of mastication, ocular, and nasal functions in the face of trauma victims, estimating their recovery time after surgical treatment. We analyzed 114 medical records of patients treated at the Hospital Montenegro, who attended follow-up consultations for up to 180 days. For analysis of the recovery time, we performed survival analysis, followed by COX analysis. We observed that half of the patients recovered their functions within 20 days. The average time for recovery from trauma in the zygomatic-orbital-malar-nasal complex was 11 days, and in the maxillary-mandibular complex, 21 days (HR: 1.5 [0.99 2.3], p = 0.055).

RESUMO O entendimento da causa, da gravidade e do tempo decorrido para o restabelecimento das funções de lesões maxilofaciais pode contribuir para o estabelecimento de prioridades clínicas objetivando o efetivo tratamento e prevenção dos traumatismos de face. Assim, o objetivo deste estudo foi compreender quais os fatores associados ao restabelecimento das funções mastigatórias, oculares e nasais em vítimas de trauma de face, estimando o tempo para recuperação das funções, após o tratamento cirúrgico. Foram analisados 114 prontuários de pacientes atendidos no Hospital de Montenegro que compareceram às consultas de acompanhamento por até 180 dias. Para a análise do tempo para a recuperação, foi realizada a análise de sobrevida, seguida da análise de COX. Observou-se que metade dos pacientes recuperaram as funções em até 20 dias, sendo que o tempo médio para recuperação dos traumas no complexo zigomático-orbitário-malar-nasal foi de 11 dias e do complexo maxilo - mandibular de 21 dias (HR: 1,5 (0,99 - 2,3) p=0,055). Embora o restabelecimento das funções tenha atingido taxas elevadas após abordagem cirúrgicas, faz-se necessária a análise dos casos de insucessos bem como os impactos econômicos e as estratégias de prevenção associados aos traumas de face a fim de qualificar o serviço prestado à população.

Avaliação da dureza Vickers de resinas tipo Bulk Fill: estudo in vitro / Evaluation of Vickers Hardness the Bulk Fill Type Resins: In vitro study

Este estudo teve como objetivo verificar a dureza Vickers superficial e profunda de duas resinas compostas tipo flow. As amostras foram divididas em dois grupos: um grupo para resina composta de incremento único, Filtek Bulk Fill Flow e outro para resina composta convencional, Filtek Z350 XT Flow. Foram confeccionados 30 corpos de prova, 15 para cada grupo. Estes corpos de prova foram submetidos a um durômetro metalográfico para verificação da dureza Vickers. Para análise estatística dos resultados foi utilizado o teste t Student e o teste Anova, demonstrando que a média de dureza da resina tipo bulk no topo foi de 26,08±2,04, e dureza no base de 18,58±3,19 e para a resina Z350 a média de dureza no topo foi de 43,15±2,79 e na base de 21,89±4,36. Obtendo valores de p tanto entre os grupos quanto dentro dos grupos ≤0,05. Conclui-se que a resina composta Filtek Z350 Flow, apresentou dureza Vickers superior à resina Filtek Bulk Flow, tanto na parte superficial quanto na parte profunda, porém sua correlação entre superficial e profunda foi de 51%. Já o material de incremento único obteve melhor resultado nesta correlação, 71%. Palavras-chave: resinas compostas; testes de dureza; polimerização.

This study aimed to verify the superficial and deep Vickers hardness of two flow type composite resins. The samples were divided into two groups: a single increment composite resin group, Filtek Bulk Fill Flow and another for conventional composite resin, Filtek Z350 XT Flow. Thirty specimens were prepared, 15 for each group. For the statistical analysis of the results the Student's T test was used, showing that the average hardness of the top bulk resin was 26.08, with a standard deviation of 2.04 and a hardness of 18.58 with standard deviation of 3.19 and for the Z350 resin the average hardness at the top was 43.15, with a standard deviation of 2.89 and at the bottom of 21.89, with a standard deviation of 4.51. Based on the results of this study, it can be concluded that the Filtek Z350 Flow Composite resin presented Vickers hardness superior to Filtek Bulk Flow resin, both in the superficial and deep part, but its correlation between superficial and deep was 51%, while the material of single increment obtained a better result in this correlation, 71%
