RESUMO

Objective: Guided Bone Regeneration (GBR) is a dental surgical procedure that uses barrier membranes to prevent soft tissue invasion and conduct new bone growth. This study aimed to define a Prognosis Recovery score (PR score) to objectively classify post-surgery responders from non-responder patients who underwent GBR using Cone Beam Computed Tomography (CBCT). Methods: This prospective-observational-longitudinal-cohort study recruited 250 individuals who were assigned to: Conventional-Apical-Surgery (CAS, n = 39), Apical-Surgery using human fascia lata Membrane placement (ASM, n = 42), and Apical-Surgery using human fascia lata Membrane placement and lyophilized allograft Bone powder (ASMB, n = 39); and Apical-Surgery using collagen membrane Porcine origin and Bovine Bone-matrix (ASPBB, n = 130), an independent external validation cohort. Surgery was performed, and evolution was monitored by CBCTs at 0, 6-, 12-, 18-, and 24 months post-surgery. Results: Normalized lesion volumes were calculated, and non-linear time evolution morphology curves were characterized. The three-time evolution bone growth patterns were: a linear tendency (PR0), "S'' shaped log-logistic (PR1), and "C" cellular growth (PR2). The treatment success rates were PR2-46 %, PR2-88 %, and PR2-95 %/PR1-5% for CAS, ASM, and ASMB groups. The xenograft ASPBB counterpart achieved PR2-92 % and PR1-8%. The score PR had a sensitivity, specificity, and accuracy of 100 %. Conclusions: Patients' treatment success can be quantitatively, objectively, and precisely predicted with the Prognosis Recovery score (using only two CBCTs), according to their biological response to allograft or xenograft materials (time-evolution bone growth curves), reducing cost and radiation exposure. Clinical significance: Through digital imaging and bioinformatic analysis of bone regeneration observed in CBCTs, we defined a Prognosis Recovery (PR) score using only two CBCT volume assessments (0 and 6 months). The PR score allowed us to define three time-evolution curves depending on the biomaterials used and to classify patients in a quantitative, objective, and accurate way.

This study aimed to apply usability and utility tests to the Dental Trauma application (app), available for free in Portuguese on the App Store and Play Store. Students and dentists participated in the study (n = 20). The System Usability Scale (SUS) test was used for usability analysis, and the Technology Acceptance Model (TAM) test, adapted to the dental trauma context, was used for utility analysis. The Mann-Whitney test was applied to compare SUS scores between students and dentists, and the Spearman test was used to correlate utility questions. The SUS score at the 50th percentile was 83.75. Scores above 68 are classified as acceptable. The Mann-Whitney test did not show a significant difference in the SUS score when analyzing dentists and dental students separately (p = 0.442). The app was widely evaluated as useful (95% to 100%), with robust, positive, and significant correlations observed between responses to each question. However, it does not cover traumas in deciduous teeth, presenting an opportunity for updating or developing other apps. The Dental Trauma app fulfilled both usability and usefulness criteria, garnering an "excellent" rating in its outcomes. Users acknowledged its utility as a valuable technological tool aiding professionals in diagnosis, management, and comprehension of dental trauma-related concepts (AU).

RESUMO

BACKGROUND: The comprehension of the interests of Internet users regarding their health-related searches may reveal the community's demands about oral health. The study aimed to characterize the interests of Google users related to mouthwash in Australia, Brazil, Chile, Japan, Mexico, Russia, the United Kingdom, the United States, Saudi Arabia and South Africa applying the Google Trends. METHODS: This longitudinal retrospective study analysed the mouthwash-related interest of Google users from January 2004 to December 2020. The monthly variation of relative search volume (RSV) and the main queries related were determined using Google Trends. Autoregressive integrated moving average (ARIMA) forecasting models were built to establish the predictive RSV values for mouthwash for additional 12 months. Auto-correlation plots and a general additive model (GAM) were used to diagnose trends and seasonality in RSV curves. In addition, the influence of social isolation related to the outbreak of COVID-19 were analysed. RESULTS: The RSVs curves showed a considerable increase in searches related to mouthwash to AUS, BRA, JAP, MEX, GBR and USA (RSV > 25), while the growth was slight to CHI, KSA, RSA and RUS (RSV < 25) over the years, without influence of monthly seasonality. All countries showed a significant increase in mouthwash interest after the outbreak of COVID-19, except for KSA and RUS. The mouthwash-related searches were associated to specific brands or chemical compositions, treatments, whitening agents, homemade mouthwash and indications for the 'best mouthwash'. CONCLUSIONS: In general, there was an increasing interest of Google users in mouthwash-related topics between 2004 and 2020. In addition, in most countries, there was an expansion in searches during the social isolation of the COVID-19 pandemics.

RESUMO

ABSTRACT Objective: This study evaluated the accuracy and precision of digital models acquisition using a home-built, low-cost scanning system based on the structured light method. Methods: a plaster model (PM) was scanned using the experimental device (SL) and a dental desktop scanner (DS). The teeth dimensions of PM and SL models were measured in triplicate, with a caliper and digitally, respectively. The agreement of the measurements of each model was evaluated using the intraclass correlation coefficient, and the validity between the different measurement techniques was assessed using the Bland-Altman analysis. The accuracy and precision of the models were qualitatively investigated using the mesh superposition of the SL and DS models. Results: A high intraclass correlation coefficient was observed in all models (PM=0.964; SL1=0.998; SL2=0.995; SL3=0.998), and there was no statistical difference between the measurements of the SL models (p>0.05). PM and SL model measurements were found to be in good agreement, with only 3.57% of the observed differences between the same measurement being located outside 95% limits of agreement according to Bland and Altman (0.43 and -0.40 mm). In the superimpositions of SL-SL and SL-DS models, areas of discrepancy greater than 0.5 mm were observed mainly in interproximal, occlusal, and cervical sites. Conclusion: These results indicate that the home-built SL scanning system did not possess sufficient accuracy and precision for many clinical applications. However, the consistency in preserving the dental proportions suggests that the equipment can be used for planning, storage, and simple clinical purposes.

RESUMO Objetivo: Este estudo avaliou a acurácia e a precisão da aquisição de modelos digitais utilizando um sistema de digitalização caseiro e de baixo custo baseado no método de luz estruturada. Material e Métodos: Para isso, um modelo de gesso (MG) foi digitalizado utilizando o dispositivo experimental (LE) e um scanner dental de mesa (SD). As dimensões dos dentes dos modelos MG e LE foram medidas em triplicata com um paquímetro e digitalmente, respectivamente. A concordância das medidas de cada modelo foi avaliada usando o coeficiente de correlação intraclasse, e a validade entre as diferentes técnicas de medição foi avaliada usando a análise de Bland-Altman. A acurácia e a precisão dos modelos foram investigadas qualitativamente usando a sobreposição de malhas dos modelos LE e SD. Resultados: Um alto coeficiente de correlação intraclasse foi observado em todos os modelos (MG=0,964; LE1=0,998; LE2=0,995; LE3=0,998) e não houve diferença estatística entre as medições dos modelos LE (p>0,05). As medições dos modelos MG e LE mostraram boa concordância, com apenas 3,57% das diferenças observadas entre as mesmas medições localizadas fora dos limites de concordância de 95% de acordo com a análise de Bland-Altman (0,43 e -0,40 mm). Nas sobreposições dos modelos LE-LE e LE-SD, foram observadas áreas de discrepância maiores que 0,5 mm principalmente nos sítios interproximais, oclusais e cervicais. Conclusões: Esses resultados indicam que o sistema de digitalização por luz estruturada caseiro não possui precisão e acurácia suficientes para muitas aplicações clínicas. No entanto, a consistência na preservação das proporções dentárias sugere que o equipamento pode ser usado para planejamento, armazenamento e propósitos clínicos simples.

RESUMO

Abstract The Internet is a growing source of knowledge and can provide information about oral health. This ecological study aimed to characterize the interests in toothpaste among Google users from different countries. Our hypothesis was that there would be an increase in Google users' interest in information about toothpaste. This retrospective longitudinal ecological study analyzed the toothpaste-related interest of Google users from 10 countries between January 2004 and December 2020. The monthly variation in relative search volume (RSV) and the main related queries were determined using Google Trends. Autoregressive integrated moving average (ARIMA) forecasting models were built to establish the predictive RSV values for toothpaste for an additional 12 months. Autocorrelation plots and the generalized additive model (GAM) were used to diagnose trends and seasonality in RSV curves. Additionally, the influence of social isolation related to the outbreak of COVID-19 was analyzed. Although not detected by autocorrelation function (ACF) and partial autocorrelation function (PACF) analyses, the heuristic analysis showed an increase in the interest in toothpaste-related information in all countries, with a stable trend observed in the 12-month forecasts, except for the increases in the United Kingdom and South Africa. Also, GAM analyses demonstrated a non-significant monthly or quarterly seasonal influence on data. In addition, social isolation during the COVID-19 pandemic did not influence the online information-seeking behavior of Google Search users linked to this topic. We confirmed the hypothesis that the interest of Google Search users in information about toothpaste increased in all of the 10 assessed countries.

RESUMO

The aim of this study wastoanalyse the acceptance of technology by professors and the adherence of dental students to virtual teachingduring the social distancing period due to the coronavirus disease (COVID-19) pandemic. This was a retrospective observational cross-sectional study that involved the anonymous opinion of dental schoolprofessors. After each virtual class, the professorsfilled out the e-questionnaire aboutthe remote activities(discipline identification, method used, number of students, satisfaction of the professor, and a technology acceptance model questionnaire) performed between 18 March and 18 May (60 days of virtualisation of theoretical classes during interruption of face-to-face classes). This study showed a good acceptability of this learning technologyby professors(TAM score 81.82 ± 11.79). During the pandemic, live video conferencing classes (n = 632, 63.6%) were the most preferred method of teachingby professors, followed by previously recorded video lessons (n = 403, 40.5%). Theacceptability of professors was strongly associated with the perception of the quality of interaction (p <0.001).Higherstudentparticipation was significantly associated with live videoconference classes (p = 0.019).Prioravailability of articles or documents for study (p = 0.028)andthe absence of technological complications during the virtual classes (p = 0.003)significantly increased acceptability.In conclusion, the virtual class technology usedduring the COVID-19pandemic period was well accepted by professors at a dental school and had good adherence by students, especially in videoconferencing classes (AU).

O objetivo deste estudo foi analisar a aceitação da tecnologia por professores e a adesão dos alunos de odontologia ao ensino virtual durante o período de distanciamento social devido à pandemia do coronavírus (COVID-19). Este foi um estudo transversal observacional retrospectivo que envolveu a opinião anônima de professores de escolasde odontologia. Após cada aula virtual, os professores preencheram um questionário sobre as atividades remotas (identificação da disciplina, método utilizado, número de alunos, satisfação do professor e questionário do modelo de aceitação de tecnologia) realizado entre 18 de março e 18 de maio (60 dias de virtualização das aulas teóricas durante a interrupção das aulas presenciais). Este estudo mostrou uma boa aceitabilidade desta tecnologia de aprendizagem pelos professores (pontuação TAM 81,82 ± 11,79). Durante a pandemia, aulas de videoconferência ao vivo (n = 632, 63,6%) foram o método de ensino preferido pelos professores, seguido por vídeo aulas previamente gravadas (n = 403, 40,5%). A aceitabilidade dos professores esteve fortemente associada à percepção da qualidade da interação (p <0,001). A maior participação dos alunos foi significativamente associada às aulas de videoconferência (p = 0,019). A disponibilidade prévia de artigos ou documentos para estudo (p = 0,028) e a ausência de complicações tecnológicas durante as aulas virtuais (p = 0,003) aumentaram significativamente a aceitabilidade. Concluindo, a tecnologia da aula virtual usada durante o período pandêmico do COVID-19 foi bem aceita pelos professores de uma faculdade de odontologia e teve boa aderência dos alunos, principalmente nas aulas de videoconferência (AU).

RESUMO

O uso das Tecnologias de Informação e Comunicação (TIC) para a troca de dados e informações em Odontologia, provendo serviços de saúde em situações em que seja necessário transpor barreiras geográficas, temporais, sociais e culturais é chamado de Teleodontologia. O objetivo dessa revisão integrativa foi analisar o panorama situacional global da Teleodontologia. Foram selecionados artigos científicos publicados nos últimos 10 anos, na íntegra, tanto em português quanto em inglês. A busca dos periódicos foi realizada nas bases de dados Scientific Eletronic Library Online, Literatura Latinoamericana e do Caribe em Ciências da Saúde e PubMed, por meio da combinação dos seguintes descritores "Telemedicine", "Dentistry", "Distance, Education", nas línguas portuguesa e inglesa. Foram encontrados 340 artigos, sendo 14 incluídos para avaliação final, sendo o PubMed a base de dados que mais prevaleceu (71,4%). A maioria dos estudos (85,7%) foi incluída no nível IV de evidência. Foram identificados estudos informando sobre o uso dessa tecnologia para minimizar as barreiras geográficas e fornecer uma assistência adequada às populações mais vulneráveis e outros sobre relatos de profissionais, estudantes de Odontologia e pacientes quanto ao uso da Teleodontologia. Concluiu-se que a Teleodontologia é uma realidade global, mas ainda necessita de disseminação de suas experiências na comunidade científica, para sua consolidação como uma ferramenta educativa e de assistência à saúde (AU).

The use of Information and Communication Technologies (ICT) for the exchange of data and information in Dentistry, providing health services in situations where it is necessary to overcome geographical, temporal, social and cultural barriers is called Teleodontology. The objective of this integrative review was to analyze the overall situational panorama of Teleodontology. Scientific articles published in the last 10 years have been selected, in full, in portuguese and in english. The search for the journals was carried out in the Scientific Eletronic Library Online databases, LILACS and PubMed, by means of combining the following descriptors: "Telemedicine", "Dentistry", "Education, Distance", in portuguese and english. A total of 340 articles were found, of which 14 were included for final evaluation, with PubMed the most prevalent database (71.4%). Most studies (85.7%) were included in level 4 evidence. Were identified studies reporting the use of this technology to minimize geographical barriers and to provide adequate assistance to the most vulnerable populations and others on reports from professionals, dentists and patients regarding the use of Teleodontology. It was concluded that Teleodontology is a global reality, but still needs to disseminate its experiences to the scientific community, for its consolidation as an educational and health care tool (AU).

RESUMO

Dentistry increasingly uses Information and Communication Technology (ICT), which has impact on teaching, research, the profession and dental care in general. However, there is a lack of valid information on ICT resources and use in Latin America. This was a descriptive, cross-sectional, multi-center, interdisciplinary study, the aim of which was to conduct a survey on how extensively ICT is used in Dentistry in Latin American countries by enquiring into two primary components: 1) use of ICT in student training and 2) use of ICT by professionals in consulting rooms and services. Two questionnaires on ICT were prepared: one for teachers/researchers and another for students/professionals. We received 94 answers from teachers/researchers at universities in the region providing information on ICT resources for teaching (type and implementation) and 221 answers from professionals (personal use and use in healthcare). Data are presented as absolute relative frequencies and analyzed quantitatively as percentages. RESULTS: 1) Teachers highlight ICT as an instrument for development, democratization and fairness in access to knowledge for higher education. 2) ICT supports collaborative learning and generates other innovative resources (e.g. simulators). 3) Innovations in telemedicine and experiences with electronic clinical history were identified in Brazil, Uruguay and Colombia. These results are a basis upon which to reach a consensus regarding a set of ICT indicators which are comparable at regional level and serve as input to unify the design and implementation of ICTs experiences in both teaching and dental care in Latin America.

La Odontología utiliza en forma creciente las Tecnologías de la Información y la Comunicación (TIC) impactando en la enseñanza, la investigación, la profesión y la atención odontológica en general. Sin embargo, no se cuenta con información válida sobre los recursos e utilización de las TIC en latinoamérica. La investigación representó un estudio descriptivo, de corte transversal, multicéntrico e interdisciplinario, cuyo objetivo fue realizar un relevamiento del grado de informatización en Odontología en países latinoamericanos indagando dos componentes principales en el empleo de las TIC: 1) en la formación de estudiantes y 2) por parte de los profesionales en consultorios y servicios. Se realizaron cuestionarios a referentes TIC: uno para docentes/investigadores y otro para estudiantes/profesionales. Se recibieron 94 respuestas de docentes/investigadores de universidades de la región dando cuenta de los recursos TIC para la enseñanza (tipo e implementación) y 221 de profesionales (personal y en la asistencia clínica). Los datos recogidos fueron analizados cuantitativamente con tabulación en porcentaje y se presentan en frecuencia relativa absoluta. Resultados: 1) Los docentes enfatizan a las TIC como instrumento de desarrollo, democra tiza ción y equidad en el acceso al conocimiento en educación superior. 2) Las TIC apoyan el aprendizaje colaborativo y generan otros recursos innovadores (ej: simuladores). 3) Se identificaron innovaciones en telemedicina y experiencias con historia clínica electrónica en Brasil, Uruguay y Colombia. Los resultados constituyen una base para consensuar un conjunto de indicadores TIC comparables a nivel regional y sirven como insumo para unificar el diseño e implementación de las experiencias TIC tanto en enseñanza como en la asistencia odontológica en Latinoamérica.

RESUMO

ABSTRACT The computer-aided design (CAD) and computer-aided manufacturing (CAM) process chain for dental restorations starts with taking an impression of the clinical situation. For this purpose, either extraoral digitization of gypsum models or intraoral digitization can be used. Despite the increasing use of dental digitizing systems, there are only few studies on their accuracy. Objective This study compared the accuracy of various intraoral and extraoral digitizing systems for dental CAD/CAM technology. Material and Methods An experimental setup for three-dimensional analysis based on 2 prepared ceramic master dies and their corresponding virtual CAD-models was used to assess the accuracy of 10 extraoral and 4 intraoral optical non-contact dental digitizing systems. Depending on the clinical procedure, 10 optical measurements of either 10 duplicate gypsum dies (extraoral digitizing) or directly of the ceramic master dies (intraoral digitizing) were made and compared with the corresponding CAD-models. Results The digitizing systems showed differences in accuracy. However, all topical systems were well within the benchmark of ±20 µm. These results apply to single tooth measurements. Conclusions Study results are limited, since only single teeth were used for comparison. The different preparations represent various angles and steep and parallel opposing tooth surfaces (incisors). For most digitizing systems, the latter are generally the most difficult to capture. Using CAD/CAM technologies, the preparation angles should not be too steep to reduce digitizing errors. Older systems might be limited to a certain height or taper of the prepared tooth, whereas newer systems (extraoral as well as intraoral digitization) do not have these limitations.

Se recibieron 94 respuestas de docentes /investigadores de universidades de la región dando cuenta de los recursos TIC para la enseñanza (tipo e implementación) y 221 de profesionales (personal y en la asistencia clínica). Los datos recogidos fueron analizados cuantitativamente con tabulación en porcentaje y se presentan en frecuencia relativa absoluta. Resultados: 1) Los docentes enfatizan a las TIC como instrumento de desarrollo, democra tiza ción y equidad en el acceso al conocimiento en educación superior. 2) Las TIC apoyan el aprendizaje colaborativo y generan otros recursos innovadores (ej: simuladores). 3) Se identificaron innovaciones en telemedicina y experiencias con historia clínica electrónica en Brasil, Uruguay y Colombia. Los resultados constituyenuna base para consensuar un conjunto de indicadores TIC comparables a nivel regional y sirven como insumo paraunificar el diseño e implementación de las experiencias TIC tanto en enseñanza como en la asistencia odontológica enLatinoamérica.

RESUMO

OBJETIVO: mapear os fluxos de trabalho (processos) da FO-UFG relativos ao atendimento ao paciente, incluindo aspectos administrativos, atendimento clínico, ensino, pesquisa e extensão, identificando onde e quais recursos computacionais seriam introduzidos. MÉTODO: Entrevistas exploratórias/ouvidoria com informantes-chave foram realizadas. Essas informações foram registradas utilizando a notação BPMN (Bussines Process Modeling Notation). RESULTADOS: Foram obtidos 15 fluxos de trabalho, distribuídos em 4 categorias: disponibilização de vagas, agendamento, movimentação de prontuários e faturamento. Três módulos de um sistema computacional do Hospital das Clínicas-UFG foram adaptados e utilizados para otimizar a realização dos fluxos mapeados, bem como o sistema de regulação da Secretaria Municipal de Saúde de Goiânia-GO. CONCLUSÃO: Apesar da incipiente implementação desses processos não permitir uma avaliação dos impactos, acreditamos num aprimoramento da gestão da informação, integração com SUS, melhoria da qualidade da assistência à saúde e reorientação da formação do estudante da FO-UFG, segundo as Diretrizes Curriculares Nacionais.

OBJECTIVE: to map the workflows (processes) of the FO-UFG relating to patient care, including administrative aspects, clinical care, teaching, research and extension, identifying where and what computer resources would be introduced. METLHOD: Exploratory interviews / ombudsman with key informants was held. These data were recordedusing BPMN (Bussines Process Modeling Notation). RESULTS: We obtained 15 workflows, distributed in four categories: availability of jobs, scheduling, handling of patient records and billing. Three modules of a computer system at the Hospital das Clinicas-UFG have been adapted and used to optimize the performance of flows mapped, and the systemof regulation of the Secretariat of Health of Goiânia-GO.

RESUMO

O objetivo do presente estudo foi avaliar as competências em relação às Tecnologias de Informação e Comunicação (TICs) de estudantes de Odontologia. Um estudo transversal foi realizado com os estudantes de Odontologia da Universidade Federal do Rio Grande do Sul, Brasil. Os dados foram coletados através de um questionário previamente validado pelo Centro de Ciências de Saúde Oral da Universidade de Malmö e submetido ao processo de adaptação transcultural para o português. Os resultados foram transformados em escores conforme literatura prévia e categorizados para as comparações. Análise descritiva, qui-quadrado e teste exato de Fischer foram utilizados. O escore de competência em relação às TICs foi considerado muito bom e apresentou relação com o nível de escolaridade materno. Já o escore de importância das TICs foi mediano e relacionado à idade. Concluiu-se que os estudantes de Odontologia apresentaram bom domínio das ferramentas de TICs e nível moderado em relação à importância atribuída ao uso odontológico dessas tecnologias (AU).

The purpose of the present study was to evaluate the competence of the students to use technologies in dental educational. A cross-sectional study was done with dental students of a university of the south of Brazil. It was used a questionnaire previously validated by the Center Oral Health Sciences of University of Malmö (Sweden) and adapted to Portuguese. The collected data were transformed into scores based on Mattheos et al. (2005). For analysis purposes, scores and sociodemographic variables were categorized. The descriptive analyses was realized, Chi Square and Exact Fischer`s tests were used to test the association between the sociodemographic data and the scores regarding the Information and Communication Technologies (ICT). The mean competence score was considered very good and associated with education level of the mothers. The mean importance score was regular and associated with age. It was concluded that the students of a university of south of Brazil had a very good level regarding the competence of the use of ICT even though moderate level in relation to the importance was given to dental use of these technologies (AU).

RESUMO

Objetivo: Analizar el uso de las tecnologías de información y comunicación (TIC) por odontólogos que egresaron a partir de 2002 en el estado de Rio Grande do Sul Brasil. Método: Análisis estadístico descriptivo de los datos de 217 cuestionarios on line con el software SPSS y Test Chi-Cuadrado para la obtención de los porcentajes de las variables de comparación (p<0,05). Resultados: El 61,8% son graduados en facultades públicas y 55,8% tiene, al menos, una especialidad. El consultorio particular como lugar de trabajo surge en 62,2% de las respuestas; 88,9% no utilizan la historia clínica electrónica, siendo la TIC que más desean incorporar a su práctica, constando en el 53,6% de las respuestas. El 87,2% considera que la informatización ayuda en la práctica clínica reconociendo “agilidad” el 78,9%. La mayor dificultad para la incorporación fue el alto costo (67%). Conclusión: La mayoría de los participantes posee equipamientos electrónicos, pero esa práctica no se extiende al consultorio y menos aún a servicios públicos. La informatización ayuda en la práctica clínica, brindando mayor agilidad y practicidad.

RESUMO

Objetivo: Conhecer a percepção do Magistrado Brasileiro quanto aos meios de provas digitalizadas. Métodos: Foram encaminhados 137 e-mails para magistrados das cinco regiões do País, com a questão: ?Muito se tem comentado, com prós e contras, a utilização de radiografias digitalizadas (armazenadas em programas de computador) em detrimento da radiografia convencional (chapas, raios-X). Qual é a percepção do Magistrado quanto aos meios de prova digitalizados??. Buscou-se coletar depoimentos por escrito dos sujeitos da pesquisa que permitissem o acesso aos dados da realidade de caráter subjetivo. Utilizou-se como estratégia metodológica em pesquisa qualitativa a construção do Discurso do Sujeito Coletivo. Resultados: Recebeu-se 105 respostas via mensagem eletrônica (e-mail) contemplando a maioria dos estados do país.Conclusão: Após a análise das respostas pôde-se concluir que os documentos digitalizados podem ser utilizados, não havendo vedação legal de seu aproveitamento, desde que, possa ser constatado, inclusive por perícia, se necessário, que são arquivos que representam com exatidão o fato, sem falsificações ou outras formas de macular a verdade.

Objective: Investigate how Brazilian magistrates perceive legal digital evidence. Methods: A total of 137 e-mails were sent emails to magistrates of the five regions of the country, with the question: ?Much has been discussed, with pros and cons, the use of digitized radiographs (stored in computer programs) rather than conventional radiography (plates, beams -X). What is the perception of the Magistrate as the evidence digitized? ?. We tried to collect written testimony of the research subjects to allow access to data from the subjective nature of reality. It was used as a methodological strategy in qualitative research the construction of the Collective Subject Discourse. Results: 105 responses was received via electronic mail (email) covering most states. Conclusion: After reviewing the responses it was concluded that the scanned documents can be used, with no legal seal its use, since that can be seen, even by expertise, if necessary, which are files that accurately represent the fact without forgery or other forms of macular truth.
