ABSTRACT
ABSTRACT Digital dentistry is a ubiquitous phenomenon nowadays but it requires access to technologies and learning curve. To aid digital workflow implementation, digital steps can be progressively incorporated in conventional workflows. We aimed to demonstrate a multidisciplinary oral rehabilitation performed mixing conventional procedures with digital open-source software programs and low-cost devices. A 46-year-old female patient had photographs, intraoral scans, and cone-beam computed tomography obtained and used in combination with conventional clinical exams to develop a treatment plan. Power point software was used for digital smile planing and Horos for digital implant planning. The digital dataset were used to guide conventional clinical procedures (scaling and root planning, gingivoplasty, in-office tooth bleaching, fiber-post restoration, implant and bone graft placement, teeth preparation, and protheses design and milling). The inclusion of digital steps in the conventional workflow enabled the performance of rehabilitation procedures with reduced clinical time and increased predictability, favoring the overall workflow and the communication among the different dental specialties. A mixed workflow can progressively lead to an exclusively digital workflow as technologies become accessible and learning curve is coped.
RESUMO Atualmente, a Odontologia digital é um fenômeno onipresente, contudo exige acesso à tecnologia e curva de aprendizado. Para auxiliar na implementação de fluxos de trabalho digitais, etapas digitais podem ser progressivamente incorporadas nos fluxos de trabalho convencionais. Nosso objetivo foi demonstrar uma reabilitação oral multidisciplinar realizada combinando procedimentos convencionais e ferramentas digitais de baixo custo e acesso aberto. Uma paciente de 46 anos teve fotografias, exames intraorais e tomografia computadorizada de feixe cônico obtidos e usados em combinação com exame clínico convencional para desenvolvimento de um plano de tratamento. O software Power Point foi utilizado para o planejamento digital do sorriso e o Horos para o planejamento digital dos implantes. O conjunto de dados digitais foi usado para orientar a execução dos procedimentos clínicos convencionais (raspagem e alisamento radicular, gengivoplastia, clareamento dental, restauração com pino de fibra de vidro, inserção de implantes e enxerto ósseo, preparos protéticos e design e fresagem protética). A inclusão de etapas digitais no fluxo de trabalho convencional permitiu redução do tempo clínico na realização da reabilitação aliado à maior previsibilidade, favorecendo o fluxo de trabalho e a comunicação entre as diferentes especialidades odontológicas. O fluxo de trabalho misto pode progressivamente levar a um fluxo de trabalho exclusivamente digital à medida que as tecnologias se tornem acessíveis e a curva de aprendizado superada.
ABSTRACT
HIGHLIGHTS This scoping review summarizes the findings of clinical trials using methylene blue (MB) for the treatment of various health conditions. This research method allowed mapping main findings, clarifying research topics, and identifying gaps in the literature.
Abstract studies evaluating effective drugs for health conditions are of crucial importance for public health. Methylene blue (MB) is an accessible synthetic drug that presents low toxicity and has been used in several health areas due to its effectiveness. Objective: this scoping review aims to provide a comprehensive overview of relevant research regarding the use of MB for the treatment of health conditions. Methods: a five-stage framework Arksey and O'maley scoping review was conducted. The literature was searched in Cochrane Library database using Mesh term "methylene blue". Data were collected by two independent reviewers and submitted to descriptive synthesis. Results: The search resulted in 429 records, from which 16 were included after exclusion criteria were applied. The therapeutic use of MB was identified for acute conditions (malaria and septic shock), chronic conditions (discogenic back pain, bipolar disorder, refractory neuropathic pain, and post-traumatic stress disorder), and postoperative care (vasoplegic syndrome, and pain after haemorrhoidectomy, lumbar discectomy, and traumatic thoracolumbar fixation). Conclusion: there is much evidence emerging from clinical trials about the therapeutic use of MB for acute, chronic, and postoperative conditions; however, many gaps were identified, which open further avenues for future research.

Aim: To compare the accuracy (trueness and precision) of cost-accessible three-dimensional (3D) printed models. Methods: A maxillary typodont (MM) was scanned and printed 10 times in polylactic acid, resulting in 10 digital models (DMs). Polyvinylsiloxane impressions were made to obtain 10 conventional stone models (SMs). All models were scanned and imported to CloudCompare software. The total area and three locations of interest were evaluated (zenith to incisal [Z-I], canine to canine [C-C], and first molar to canine [1M-C] distances). Total area evaluations were performed by aligning the MM and experimental models using the best-fit algorithm and were compared using the Haussdorf distance. The distances between points of interest were measured using the point-picking tool at the same 3D coordinates. The mean volumetric deviations were considered for trueness analysis. Precision was set as the standard deviation. Statistical differences were evaluated using the Student's t-test. Results:Total area volumetric comparisons showed that DMs showed superior trueness and precision (-0.02 ± 0.03) compared to the SMs (0.37 ± 0.29) (P < 0.001). No differences between the models were observed for Z-I (P = .155); however, SMs showed fewer deviations for C-C (P = .035) and 1M-C (P = .001) than DMs. Conclusions: The DMs presented superior trueness and precision for total area compared to the SMs; however, the SMs were more accurate when points of interest were evaluated

Introdução: O diagnóstico e o tratamento precoce de anquiloglossia em bebês favorece o desenvolvimento adequado das funções orofaciais. O conhecimento popular sobre o teste da linguinha (TL) pode disseminar sua realização. Objetivo: Verificar o conhecimento sobre o TL e sua relação com o perfil sociodemográfico de gestantes. Material e método: Foram investigadas 427 gestantes que realizaram o pré-natal em um hospital escola do sul do Brasil, no período de maio a dezembro de 2017. As informações foram obtidas por meio de questionário individual contendo perguntas sobre as características sociais, demográficas e gestacionais da gestante, e o conhecimento sobre o teste da linguinha. Os dados foram analisados por estatística descritiva e as associações realizadas com o teste qui-quadrado. Resultado: Os resultados demonstraram que 33 (7,7%) gestantes conhecem e 45 (10,5%) possuem informações equivocadas sobre o TL. Gestantes com grau de escolaridade (p=0,028) e renda familiar (p=0,002) maiores são mais propensas a conhecer o teste. Profissionais da enfermagem são os principais provedores da informação (64,1%). Conclusão: O conhecimento de gestantes sobre o TL é superficial, especialmente entre as de menor escolaridade e renda, o que acentua a necessidade de estratégias públicas com foco em melhorar a qualidade da assistência oferecida ao binômio mãe-filho.
Introduction: The early diagnosis and treatment of ankyloglossia in infants favors the adequate development of orofacial functions. The knowledge about the tongue screening test (TL) may disseminate its realization. Objective: The aim of this study was to verify the knowledge about the neonatal tongue screening test (TL) and its relation with the sociodemographic profile of pregnant women. Materials and method: A total of 427 pregnant women receiving prenatal care at a school hospital in southern Brazil from May to December 2017 were investigated. The information was collected through an individual questionnaire containing information about the pregnant woman's sociodemographic profile and gestational characteristics and knowledge about the TL. Data were analyzed by descriptive statistics and the associations performed with the chi-square test. Result: The results showed that 33 (7.7%) of the pregnant women knew and 45 (10.5%) had misinformation about the TL. Pregnant women with higher education (p=0.028) and higher family income (p=0.002) were more likely to know the test. Nursing professionals were the main providers of the information (64.1%). Conclusion: It is possible to conclude that the knowledge of pregnant women about the TL is superficial, especially among those with lower schooling and income, and it emphasizes the need for public strategies focused on improving health care offered to the mother-baby binomial.
