On the forensic relevance of tattoos: distinguishing black inks with energy dispersive spectroscopy and backscattered scanning electron microscopy.

PURPOSE: This study aimed to analyze black tattoo inks by means of energy dispersive spectroscopy and backscattered scanning electron microscopy. METHODS: The sample consisted of five types of commercial tattoo pigments of the black colour (Easy Glow™, Electric Ink™, Iron Works™, Master Ink™, and Viper™). An Energy Dispersive Spectroscopy (EDS) detector (Silicon Drift Detector - SDD - type) attached to a Scanning Electron Microscope (SEM) device (Tescan Vega3 LMU, Libusina, Czech Republic) was used. X-ray characteristic signs were detected for each tattoo ink in an interval between 0 and 2.5 keV. The electron acceleration potential in the microscope was 15 keV. Two regions were analyzed for each sample (n = 10). On each region, a micrography of backscattered electrons (BSE) was obtained. Means and standard deviations (SD) of the weight percentages (Wt%) were calculated. RESULTS: C and O were predominant, with a mean O/C ratio between 2.69 and 2.74 Wt%. Electric Ink and Master Ink were the most similar pigments, while Easy Glow was the most distinctive - with agglomerates of Al that had a concentration 25 × higher than other specimens. Other compounds detected in the sample were Cl and Cu. CONCLUSION: EDS and SEM were efficient to distinguish black tattoo inks. These are our preliminary outcomes on the use of EDS and SEM to analyze black tattoo inks. Thus, careful interpretation is necessary to avoid rash applications in human identification practice.

Histórico e panorama das mulheres na perícia oficial criminal (odontolegista) no Brasil / History and overview of women as forensic odontologists in the Brazilian criminal system

Forensic Dentistry is a dental specialty, historically marked by many "fathers", but few information about women in this context. The female insertion in the labor market still suffers from historical barriers, and the objective of this research was to identify the participation of the first women as Forensic Odontologists in the Brazilian Criminal Expert Services, and carry out an overview of the current number of professionals in this position and its proportion between the sexes. Data were collected on the first Forensic Odontologist in each state and the currently active professionals through the records from the Scientific Polices, Civil Polices, and Brazilian Transparency Databases for descriptive statistics. The first women as Forensic Odontologists in Brazil were from the states of Paraíba, Maranhão, and Pará (1981, 1982, and 1985, respectively). According to the Brazilian Federal Council of Dentistry, 59.69% of Specialists in Forensic Dentistry are women and in the states where data collection was possible, 57.89% of Official Forensic Odontologists are women. Despite being the majority, it is still necessary to standardize the nomenclature and create new official positions to strengthen the Forensic Odontologist profession, and encourage greater female participation. It is concluded that in 1981 there was the first Forensic Odontologist female in Brazil in the state of Paraíba and that today there is a better balance in the proportion of men and women in this position

A Odontologia Legal é uma especialidade marcada historicamente por muitas figuras "paternas", mas pouco é abordado sobre a participação das mulheres nesse contexto. A inserção feminina no mercado de trabalho ainda sofre barreiras históricas, sendo o objetivo deste trabalho a identificação da participação das primeiras mulheres na Perícia Oficial no Brasil, especificamente na condição de Peritas Odontolegistas, e realizar um panorama da quantidade atual de profissionais no cargo e sua proporção entre os sexos. Foram coletados dados sobre as primeiras mulheres a ocupar o cargo de Perita Oficial Odontolegista de cada estado e as Peritas Odontolegistas ativas atualmente por meio dos registros das Polícias Científicas, Polícias Civis e dados do Portal da Transparência para tabulação e estatística descritiva. Das respostas recebidas, as primeiras Peritas Odontolegistas Oficiais do Brasil foram dos estados da Paraíba, Maranhão e Pará, nos anos de 1981, 1982 e 1985, respectivamente. No cenário atual, de acordo com o Conselho Federal de Odontologia, 59,69% dos Especialistas em Odontologia Legal são mulheres e, nos estados onde foi possível a coleta dos dados, 57,89% dos Peritos Oficiais Odontolegistas são mulheres. Apesar de maioria na Odontologia Legal, ainda é necessário padronizar a nomenclatura e criar novos cargos oficiais no Brasil para fortalecer a profissão de Perito Odontolegista, incentivando uma maior participação feminina. Conclui-se que em 1981 tivemos a primeira Perita Oficial Odontolegista do Brasil, sendo tal fato no estado da Paraíba, e que hoje há um maior equilíbrio na proporção de homens e mulheres nesse cargo

Psiconeurodontologia, (bio)decodificação dental e os mil e um nomes para o charlatanismo odontológico no século XXI: uma revisão de escopo / Psychoneurodontology, dental (bio)decoding and a thousand terms for odontological charlatanism in the 21st century: a scoping review

Junto às tecnologias que surgem para aprimorar a Odontologia mundial, emergem temáticas que progressivamente prosperam no obscuro e na incerteza. Tais "áreas odontológicas" se caracterizam por uma roupagem prolixa e de alto apelo público (como por meio de inferências sobre o emocional e os mistérios do corpo humano). Em tempos de disseminação da psiconeurodontologia e (bio)decodificação dental, assim como da incerteza acerca de sua confiabilidade, faz-se imperativa a busca pela fundamentação científica que sustenta esta temática. Para isto, foi realizada uma revisão de escopo seguindo as recomendações do PRISMA-ScR e JBI. Uma ampla busca foi realizada em cinco bases de dados e em parte da literatura cinza. Não houve restrição quanto ao ano de publicação e nem quanto ao idioma. Os dados foram coletados e expostos na forma narrativa/descritiva. De maneira complementar, utilizou-se a ferramenta JBI para avaliação da qualidade metodológica. A busca resultou em 4.785 registros iniciais, dos quais somente dois foram classificados como elegíveis. Ambos os estudos foram detectados a partir da literatura cinzenta e consistiam em trabalhos peruanos de conclusão de curso em nível de graduação (Bacharelado) em Odontologia. Os trabalhos aferiam a ocorrência de lesão de cárie em quadrantes de dentes permanentes e decíduos e correlacionavam com um questionário psicoemocional. Os dois trabalhos concluíram em prol da aplicação da psiconeurodontologia e da (bio)decodificação dental como ferramentas adicionais ao armamentário diagnóstico do Cirurgião-dentista. Detectou-se alto risco de viés, em especial acerca das limitações metodológicas dos estudos elegíveis. Tendo em vista os métodos e resultados observados nos estudos elegíveis, pode-se concluir que não há fundamentação científica na psiconeurodontologia ou na (bio)decodificação dental, muito menos validade e confiabilidade para a sua aplicação na prática clínica odontológica atual

Along with the technologies that emerged to improve Dentistry worldwide, there are themes that progressively dive into darkness and uncertainty. Such "dental areas" are characterized by a verbose approach and strong public appeal (such as through inferences about the emotions and mysteries of the human body). In times of dissemination of psychoneurodontology and dental (bio)decoding, as well as uncertainty about their reliability, the search for alleged scientific foundations that support this theme is imperative. To this end, a scoping review was carried out following the recommendations of PRISMA-ScR and JBI. A broad search was carried out in five databases and part of the gray literature. There was no restriction on the year of publication or language. Data were collected and presented in narrative/descriptive form. Complementarily, the JBI tool was used to assess methodological quality. The search resulted in 4.785 initial records, of which only two were classified as eligible. Both studies were detected from the gray literature and consisted of Peruvian studies at Bachelor's degree in Dentistry. The studies measured the occurrence of caries lesions in quadrants of permanent and deciduous teeth and correlated them with a psychoemotional questionnaire. The two studies concluded in favor of the application of psychoneurodontology and dental (bio)decoding as additional tools to the dental surgeon's diagnostic armamentarium. A high risk of bias was detected, especially regarding the methodological limitations of the eligible studies. Considering the methods and results observed in the eligible studies, it can be concluded that there is no scientific basis in psychoneurodontology or dental (bio)decoding, as well as lack of validity and reliability for its application in current clinical dental practice

Avaliação das ementas e referências bibliográficas de disciplinas de Odontologia Legal no Brasil ­ uma análise documental / Evaluation of menu and bibliographical references of Legal Dentistry disciplines in Brazil ­ a documental analysis

Nesta pesquisa avaliou-se o plano de ensino de 25 faculdades do Brasil, sendo 5 faculdades por região para melhor representatividade do país. Um instrumento de coleta de dados foi construído para extração das informações necessárias, a saber: ementa e referências bibliográficas. Os dados obtidos por esta pesquisa foram tabulados em planilhas utilizando o programa Microsoft Office Excel. Inicialmente, cada frase das ementas foi transcrita para uma entrada de linha da planilha e forma associadas a 10 categorias de sentido. Foram transpostas para uma ementa provisória e proposta uma versão de ementa final. Já as referências bibliográficas foram descritas em linhas das planilhas, individualmente, e após a inclusão de todas foi feito um ranqueamento por frequência de citação. Em termos quantitativos esta pesquisa evidenciou que, as componentes curriculares de Odontologia Legal, abordam mais frequentemente em suas ementas os conteúdos relacionados às Ciências Forenses e ao Direito, sendo estas duas categorias responsáveis por 51,4% (121) das frases das ementas avaliadas e, Jorge Paulete Vanrell, é o autor mais frequentemente referenciado (80%) com sua obra Odontologia Legal e Antropologia Forense

In this research, the teaching plan of 25 colleges in Brazil was evaluated, with 5 colleges per region for better representation of the country. A data collection instrument was built to extract the necessary information, namely: menu and bibliographic references. The data obtained by this research were tabulated in spreadsheets using the Microsoft Office Excel program. Initially, each sentence of the menus was transcribed into a line entry in the spreadsheet and was associated with 10 categories of meaning. They were transposed to a provisional menu and a version of the final menu was proposed. The bibliographic references were described in lines of the spreadsheets, individually, and after the inclusion of all, a ranking was performed by citation frequency. In quantitative terms, this research showed that the Forensic Dentistry disciplines more frequently address content related to Forensic Sciences and Law in their menus, these two categories being responsible for 51.4% (121) of the sentences of the evaluated menus and, Jorge Paulete Vanrell is the author most frequently referenced (80%) with his work Odontologia Legal e Antropologia Forense

Responsabilidade profissional por lesão do nervo lingual durante exodontia de terceiro molar inferior: análise de nove processos judiciais / Professional responsibility for lingual nerve injury during lower third molar extraction: analysis of nine court proceedings

Introdução: A remoção cirúrgica dos terceiros molares inferiores apresenta o risco potencial de lesões a estruturas nobres como o nervo lingual devido sua localização anatômica. O grau de comprometimento do nervo indicará se a lesão é transitória ou permanente. A injúria nervosa pode motivar o paciente a acionar judicialmente o cirurgião-dentista, e sendo evidenciada a culpa profissional, caberá a reparação pecuniária dos danos causados ao paciente, sejam de natureza material ou moral. Objetivo: Analisar nove decisões judiciais de 1ª e 2ª instância, disponíveis no site do Tribunal de Justiça de São Paulo (TJSP), motivadas pela lesão do nervo lingual durante a exodontia de terceiro molar inferior. Metodologia: Após a leitura e análise foram extraídas informações como: perfil das partes, tempo de duração dos processos, procedência ou não da ação, valor da indenização, responsabilidade profissional e presença de TCLE. Resultados: Na primeira instância, seis dos nove casos foram julgados improcedentes; em segunda instância, quatro destas sentenças foram reformadas para procedência. No total, após decisão de segunda instância, houve procedência da ação em sete dos nove casos. Nas ações procedentes, as indenizações para dano moral variaram de R$ 5 mil a R$ 50 mil, sendo a imperícia e negligência as modalidades de culpa mais atribuídas aos profissionais. Conclusão: Sabendo-se que a lesão do nervo lingual durante a extração de terceiro molar inferior, mesmo previsível, nem sempre é evitável, verifica-se a importância do TCLE (ou documento similar) na prática clínica como instrumento de defesa jurídica do profissional, diante da alegação de falha de informação. Este documento foi mencionado em apenas três dos nove casos processuais, sendo em que em dois destes não houve constatação de falha técnica ou de informação (ação improcedente nas duas instâncias)

Introduction: Surgical removal of lower third molars presents the potential risk of injury to noble structures such as the lingual nerve due to its anatomical location. The level of nerve involvement will indicate whether the injury is transient or permanent. Nervous injury can motivate the patient to sue the dentist, and if professional guilt is evidenced, it will be up to pecuniary compensation for the damage caused to the patient, whether of a material or moral nature. Objective: To analyze nine court decisions of 1st and 2nd instances, available on the Court of Justice of State of São Paulo (Brazil) website, motivated by lingual nerve injury during lower third molar extraction. Methodology: After reading and analysis, information was extracted such as: profile of the litigating parties, duration of the processes, judge decision for the action, indemnity value, professional responsibility and presence of TCLE. Results: In the first instance, six of the nine cases were dismissed, the sentence was reformed in four cases, confirming the merits of the action in seven of the nine cases. In the cases of valid actions, compensation for moral damages ranged from R$ 5 thousand to R$ 50 thousand, with malpractice and negligence being the types of fault most attributed to professionals. Conclusion: Knowing that lingual nerve injury during mandibular third molar extraction, even if predictable, is not always avoidable, the importance of the informed consent (or similar document) in clinical practice as an instrument for the professional's legal defense is mandatory, to avoid the allegation of miss information. This document was mentioned in only three of the nine cases, and in two of these there was no finding of technical or information failure (unfounded action in both instances)

Diagnostic accuracy of the third molar maturity index (I3M) to assess the age of legal majority in Northern Brazil-population-specific cut-off values.

International guidelines for dental age assessment have recommended the use of methods based on available population-specific data. The Third Molar Maturity Index (I3M) was previously validated in several populations worldwide. This was the first study to evaluate the I3M in a northern Brazilian population and to test the diagnostic accuracy of the method to distinguish between minors and adults. The sample consisted of 1.070 panoramic radiographs retrospectively collected from females (n = 595) and males (n = 475) with ages between 16 and 22 years. I3M's original cut-off value of 0.08 was used to classify individuals below and above the age of 18. Receiver operating characteristic (ROC) curves were plotted to assess the accuracy (ACC) of the method. In females and males separately, the overall ACC was 73.1% and 80%, respectively. The overall ACC for the combined sample was 76.1%. For northern Brazilian males, the best cut-off value remained 0.08, while for females, an adjustment to 0.12 showed optimal outcomes. The new cut-off value led to an ACC of 98.5% for females, which reflected an increase of 25.5% compared to the original cut-off value. The original cut-off value proposed by I3M was applicable to the present sample of northern Brazilian individuals. Adjustments to 0.12, however, may be encouraged to enhance the performance of the method among females.

The role of women in Forensic Odontology / O papel da mulher na Odontologia Forense

This literature review aims to name the influential female pioneers who broke the conservative barriers in place for their gender and set the standards for those who followed in their paths as either dentists or forensic odontologists, with the purpose of increasing the visibility of their identities, feats, and positions of authority, hence, diminishing the states of exclusion that may be still practiced towards the recognition of their contributions to dentistry. It is our expectation that contemporary female forensic dentists can, by accessing this reading, acknowledge and promote the female performance in the forensic field, from its beginning to the present time, and be reassured of the representation and the excellence of women in it. We anticipate that all these professionals' names will not be mentioned due to lack of information from sound resources or unawareness. We also hope to witness similar literature reviews in the future

Esta revisão de literatura tem como objetivo nomear as influentes pioneiras que romperam as barreiras conservadoras de gênero e estabeleceram os padrões para aquelas que seguiram seus caminhos como dentistas forenses ou odontolegistas, com o objetivo de aumentar a visibilidade de suas identidades, feitos e posições de autoridade, diminuindo, assim, os estados de exclusão que ainda podem ser praticados para o reconhecimento de suas contribuições para a Odontologia. É nossa expectativa que as odontolegistas contemporâneas possam, ao acessar essa leitura, reconhecer e promover a atuação feminina no campo forense, desde o seu início até os dias atuais e ter a certeza da representação e da excelência da mulher nela. É possível que outros nomes não foram mencionados por falta de informação segura ou desconhecimento. Também esperamos testemunhar revisões de literatura semelhantes no futuro

Postmortem cross-sectional slicing of the frontal sinuses and comparison with antemortem anatomical imagens ­ a technical description / Secção transversal postmortem dos seios frontais e comparação com imagens antemortem ­ descrição de técnica

The anatomical features of the frontal sinuses (FS) are known as highly distinctive and potentially useful for human identification. Assessing these structures with advanced postmortem (PM) imaging, however, is not always feasible in medicolegal units worldwide. This study proposes and validates the anatomical assessment of the FS via cross-sectional slicing of the frontal bone to reproduce images comparable to antemortem (AM) axial views. The bodies of two unknown sisters with advanced decay (decomposition stage III.1) were referred for human identification. The AM data provided for comparative analysis consisted of multi-slice computed tomography (CT) and magnetic resonance images of the skull. In the lack of primary alternatives for human identification, PM assessment of the FS was considered. Justified by the mortuary facilities there were not equipped with CT devices, sequential cross-sectional slicing of the frontal bone was performed. With the skulls in supine position, the technique followed Griesinger's anteroposterior plane using an oscillating saw blade at 90°. Multiple slices (n = 20) of the frontal bone were obtained in craniocaudal direction up to the superior limit of the orbits. The outline of the FS, as well the number of lobes and position of the intersinus septum were visible and compatible with the AM data, enabling positive identification. External validation of the proposed technique was accomplished by reproducing it to successfully identify a male victim in a medicolegal institute 2,000 KM far from the original site

As características anatômicas dos seios frontais (FS) são consideradas distintivas e potencialmente uteis para a identificação humana. A análise imaginológica postmortem (PM) destas estruturas, contudo, não sempre é viável. O presente trabalho tem como objetivo a apresentação e validação de uma proposta de análise anatômica dos seios frontais utilizando a secção do osso frontal a fim de se permitir comparações com imagens axiais antemortem (AM). A corpo de um indivíduo do sexo masculino, não identificado, e em avançado estado de decomposição (estágio III.1) foi encaminhado para identificação. Os dados AM providenciados para análise comparativa consistiram em imagens de tomografia computadorizada (CT) multi-slice e ressonância magnética do crânio. Na falta de alternativas primárias para identificação humana, a análise dos seios frontais (SF). Pelo fato de que o instituto médico-legal era desprovido de unidades de Imaginologia avançada, cortes sequenciais do seio frontal foram realizados. Com os crânios em posição supina, a técnica foi conduzida seguindo o plano anteroposterior de Griesinger's com uma serra oscilatória em 90°. Secções múltiplas (n = 20) do osso frontal foram obtidas no sentido craniocaudal até o limite superior das orbitas. A anatomia dos SF, assim como o número de lobos e a posição do septo intersinual eram visíveis e compatíveis com os dados AM, viabilizando a identificação positiva. A validação externa da técnica proposta se deu durante a identificação de uma vítima do sexo masculino periciada em um instituto médico-legal 2.000Km distante do centro originalmente relatado no presente estudo

Orthodontic Records Helping to Identify A Victim of Execution

ABSTRACT: Human identification is the process that identifies an individual as a unique being, differentiating him/ her from all others. The participation of Odontology in the processes of identification is fundamental in situations of human remains. This paper aims to report a case of positive identification, through dentistry, in human remains. The forensic odontologist performed a post-morten (PM) examination, which consisted of the collection of post-mortem dental findings in human bones, collection of ante-mortem (AM) dental findings in the patient's orthodontic records, and the comparison between AM and PM information. Dental elements are widely used in the processes of human identification, since they are resistant to time and to physical, chemical and mechanical impacts. Positive identification is guided by the presence of individualizing characteristics, easily detected in dental records. It is concluded that human identification through dentistry is a safe and reliable method, since dental elements have individualizing characteristics that make the process possible.

RESUMEN: La identificación humana es el proceso que identifica a un individuo como un ser único, diferenciándolo de todos los demás. La participación de la Odontología en los procesos de identificación es fundamental en situaciones de restos humanos. Este trabajo tiene como objetivo reportar un caso de identificación positiva, a través de la odontología, en restos humanos. El odontólogo forense realizó un examen post-morten (PM), que consistió en la recolección de hallazgos dentales post-mortem en huesos humanos, recolección de hallazgos dentales ante-mortem (AM) en los registros de ortodoncia del paciente y la comparación entre AM y Información de PM. Los elementos dentales son ampliamente utilizados en los procesos de identificación humana, ya que son resistentes al tiempo y a los impactos físicos, químicos y mecánicos. La identificación positiva está guiada por la presencia de características individualizantes, que se detectan fácilmente en los registros dentales. Se concluye que la identificación humana a través de la odontología es un método seguro y confiable, ya que los elementos dentales tienen características individualizantes que hacen posible el proceso.

Usability of free software used for visualization and measurement of digital orthodontic models

The aim of this study was to evaluate the usability of the free software available that allow visualization and measurement of orthodontic digital models. 80 graduate students of orthodontics were asked to perform pre-defined tasks in a digital model through 3D Viewer ® and 3D-Tool ® software. The success in accomplishing the tasks and the time spent were recorded. To end, each participant answered a questionnaire to express their satisfaction regarding the software. There were no statistically significant difference between the software when compared to the accomplishment rates of tasks and the time spent by participants on each one. The software were evaluated as "slightly satisfactory" in several criteria. There is scope for optimization of orthodontic software by manufacturers since lack of their interface usability can discourage orthodontists' adherence to new resources that could provide benefits to their daily routine, even if they are freely available.

Proposta de inquéritos administrativo e clínico para tomada de decisão no atendimento odontológico em tempos de pandemia de covid-19 / Importance of clinical and administrative survey to dental treatment making decision in times of COVID-19 pandemic

Profissionais da Odontologia estão constantemente expostos a vários microrganismos, incluindo o novo Coronavírus (SARS-CoV-2), que apresenta alto potencial de disseminação. Considerando que durante o atendimento odontológico são gerados aerossóis com a disseminação de gotículas de saliva (potencialmente contaminada pelo vírus), a contaminação dos profissionais e pacientes poderia ser aumentada mesmo tomando-se os cuidados de biossegurança necessários. Embora o risco de contaminação durante um atendimento odontológico ainda não tenha sido estimado, a padronização de condutas, previamente e durante o atendimento odontológico, é atitude necessária para minimizar a transmissão do SARS-CoV-2 entre profissionais e pacientes. O objetivo do presente trabalho é propor um modelo de inquérito administrativo e clínico, com fundamento clínico, ético e legal, para a tomada de decisão sobre atender (ou não) um paciente com necessidades odontológicas em tempos de pandemia de COVID-19. A identificação de pacientes sintomáticos utilizando instrumentos sistematizados para coleta de informações pode minimizar o risco de contaminação por profissionais ou pacientes e, além disso, estes instrumentos podem subsidiar o profissional contra alegações infundadas, por parte dos pacientes, em casos de não atendimento.

Why are brazilian orthodontists prosecuted and convicted? an overview of the contemporary jurisprudence / Por que ortodontistas brasileiros são processados ​​e condenados? uma revisão da jurisprudência contemporânea

Orthodontics figures as one of the largest community of specialists in Brazil. Unfortunately, numbers are high not only for the professionals but also for the lawsuits against them. The aim of this study was to screen the Brazilian jurisprudence in order to identify the reasons that motivated patients against orthodontists and motivated Judges towards convictions in lawsuits. The sample consisted of 395 lawsuits retrieved from the State Civil Courts of Brazil (n=27). The lawsuits were founded on conflicts between orthodontists and patients. Case-specific legal information were registered, such as patients' main reason behind the lawsuit and the decision in second instance. Chi-square and relative risk tests were calculated to investigate the influence of research variables towards conviction. Most of the lawsuits were judged in the State of São Paulo (n=151; 38.2%) and were published between 2011 and 2017 (rho: 0.797). The main reasons behind the lawsuits against orthodontists were the dissatisfaction with treatment outcomes (n=143, 36.2%), the occurrence of periodontal disease (n=45, 11.4%) and the need for tooth extractions (n=43, 10.9%). Statistically significant outcomes were detected between convictions in first and second instances and between convictions and the contractual obligation of result (p<0.001). The combination of I) patients' dissatisfaction and II) judgments under the obligation of results in second instance figure as the main risk factors for the prosecution and conviction of orthodontists.

A Ortodontia figura como uma das maiores especialidades no Brasil. Infelizmente, os números não são elevados apenas no que concerne aos profissionais, mas também quanto aos processos judiciais contra eles. O objetivo deste trabalho foi pesquisar a jurisprudência Brasileira para identificar as razões que levam os Ortodontistas a serem processados pelos pacientes e os motivos que levam os Magistrados a condená-los. A amostra consistiu de 395 processos judiciais obtidos dos Tribunais Judiciais Brasileiros (n=27). Todos os processos descreveram lides entre Ortodontistas e pacientes. Informações demográficas e legais foram registradas, como a queixa principal do paciente ao instaurar o processo e a decisão do Magistrado em segunda instância. Os testes de Qui-quadrado e de risco relativo foram utilizados para verificar a influência das variáveis sobre o desfecho. A maioria dos processos foi julgada no Estado de São Paulo (n=151; 38.2%) e publicada entre 2011 e 2017 (rho: 0.797). O principal motivo de processo contra Ortodontistas foi a insatisfação do paciente com os resultados do tratamento (n=143, 36.2%), seguido da ocorrência de doença periodontal (n=45, 11.4%) e da necessidade de extrações (n=43, 10.9%). Resultados estatisticamente significantes foram observados entre julgamentos em primeira e segunda instância e entre condenação e julgamento sob a obrigação de resultado (p<0.001). A combinação da I) insatisfação do paciente com II) o julgamentos sob a obrigação de resultados emergiram como principais fatores de risco para condenações.

Suicidal tandem bullets to the heart with subsequent embolization - a case report.

A tandem bullet phenomenon is a rare situation in which two bullets travel nose-to-base towards the target. In terminal ballistics, a classic feature of the tandem bullet phenomenon is the presence of a single entrance wound with two or more bullets inside the body. During the autopsy, the phenomenon may result in confusion, especially related to the dynamics of the shooting. The present study reports a case of suicide by tandem bullets to the heart with subsequent bullet embolization into the aorta. A 40-year-old Caucasian woman, with a previous history of suicide, shot herself in the chest with a 0.32 revolver. During the autopsy, a single entrance wound (one centimeter in diameter) was observed in the sternal region. The injury was a close-range shot. Internally, a single wound was detected in the right atrium of the heart. Two 0.32 S&WL lead bullets were found inside the descending abdominal aorta. The bullets fitted each other perfectly in a nose-to-base position. Both bullets were tracked back to a single firearm that belonged to the victim's father using forensic ballistics. The forensic report suggested a suicide. A multidisciplinary approach involving crime scene investigation, forensic pathology and forensic ballistics is necessary to investigate tandem bullet cases. Forensic experts must be aware of this phenomenon and, more importantly, they must be aware of its unusual manifestations, such as embolization, in order to come to optimal conclusions.

Análise ético-jurídica da publicidade odontológica no Instagram / Ethical and legal analysis of Odontology-related advertisement on Instagram

A restrição à publicidade odontológica coíbe a mercantilização, resguarda a privacidade do paciente e o protege como consumidor. O objetivo deste estudo foi avaliar a adequação da publicidade na rede Instagram® ao regramento vigente. Numa amostra de 384 perfis profissionais, avaliaram-se postagens públicas à luz da Lei 5.081/1966, Código de Defesa do Consumidor e Código de Ética Odontológica. A identificação adequada não foi feita por 35,4%. Já 3,6% anunciaram especialidades não reconhecidas. A expressão "popular" foi utilizada por 27,1%. Houve publicidade abusiva (16,4%) ou enganosa (8,3%). Serviços gratuitos foram anunciados (9,4%), com divulgação de preços (5,5%). Usando a imagem do paciente (79,4%), constatou-se divulgação de resultados clínicos (72,9%). Houve identificação do paciente em 68,2%, com uso adequado da imagem em apenas 9,1% dos casos. As imagens de antes/depois foram usadas em 76,6% das postagens. As inadequações sem a imagem do paciente orbitam entre infração ética, exercício profissional ilícito e desrespeito ao direito consumerista. Conclui-se que a publicidade odontológica veiculada no Instagram® apresentou condutas ilícitas e antiéticas, com e sem o uso da imagem do paciente o que pode configurar prejuízos ao paciente, ao profissional e à Odontologia como profissão da área de saúde.

Limites de atuação da equipe de saúde bucal em um panorama global / Attribution limits of the oral health group in a global overview

Objetivo: Comparar as atribuições clínicas referentes à atuação da equipe auxiliar odontológica brasileira (Auxiliar e Técnico em Saúde Bucal) com as atribuições de outras profissões auxiliares regulamentadas no exterior (Dental Assistant, Dental Therapist; Dental Nurse; Dental Hygienist; Orthodontic Therapist). Métodos: Foram buscadas normativas e leis, nacionais e internacionais, que subsidiassem a identificação das atribuições clínicas de auxiliares odontológicos nas bases de dados Lilacs, Scielo e Pubmed. Resultados: Os resultados apontam que há diversas funções que podem ser delegadas à equipe de saúde bucal no exterior que seriam privativas dos cirurgiões-dentistas brasileiros, tanto nas áreas de diagnóstico, preventiva, clínica geral e ortodontia, quando comparadas com as leis que regem a Odontologia no Brasil. Conclusões: Dental Nurse seria uma função com correlação a Auxiliar em Saúde Bucal, já os Técnicos em Saúde Bucal apresentam menor número de funções dos que as designadas aos terapeutas e higienistas odontológicos. O Orthodontic therapist é condizente a atividades privativas do cirurgião-dentista. De forma geral, os terapeutas entram na área de competência do Cirurgião-dentista no que concerne à Lei 5081/66, que regulamenta a profissão, inclusive dentro de especialidades odontológicas, como é o caso da ortodontia.

Objective: To compare clinical attributions related to the work of the Brazilian dental assistant team ("Auxiliar e Técnico em Saúde Bucal") with attributions of other auxiliary jobs regulated abroad (Dental Assistant, Dental Therapist, Dental Hygienist, Orthodontic Therapist). Methods: National and international regulations and laws were used to support the identification of clinical attributions of dental assistants using Lilacs, Scielo, and Pubmed databases. Results: Several attributions can be delegated to the oral health team abroad that would be exclusive to Brazilian dentists, especially regarding diagnosis, preventive dentistry, general practice, and orthodontic treatment. Conclusions: Dental Nurse can be correlated to "Auxiliar em Saúde Bucal". "Técnicos em Saúde Bucal" have lesser attributions than those assigned to Dental Therapists and Hygienists. Orthodontic Therapist has attributions exclusively designated to the dentist. In general, Therapists attributions are of competence of the Dentist concerning Law 5081/66, which regulates the profession, including dental specialties, as is the case of orthodontics

Extrusion of Endodontic Material to the Maxillary Sinus: Avoidable Intercurrence? / Extrusión de Material Endodóntico al Seno Maxilar: ¿Intercurrencia Evitable?

ABSTRACT: The objective of this study is to discuss and analyze whether extrusion of endodontic material constitutes avoidable intercurrence, discussing the clinical, ethical and legal implications. Patient LSR, 31 years old, female, attended a dental consultation complaining of pain in the second left maxillary premolar (tooth 25). Radiographically, a single root canal and thickening of the periodontal ligament associated with extravasation of 8 mm of gutta percha to the maxillary sinus were observed. The first endodontic session aimed to performing the desobturation, root canal preparation and intracanal medication placement. The root canal obturation was performed in the second session. Was carried out an apical surgery that removed 2 mm from the root apex and also performed the covered with a collagen membrane. A 22 months follow-up revealed a tooth function, absence of painful symptomatology or infection, and radiographically normal periodontal ligament and bone neoformation. The second single-root premolar is the type of premolar with less distance with the floor of the maxillary sinus. In this case, the extrusion of the obturator material occurred due to the superinstrumentation of the root canal associated with the proximity of the root with the membrane of the maxillary sinus. From the ethical and legal point of view, the patient has the right to be informed about any intercurrences that may arise during or after the treatment, and the informed consent form is essencial. This document will allow the patient to make a decision about performing an endodontic treatment in which the risk of an accident or complication is imminent or that treatment failure is already expected. It is important that professionals make appropriate diagnosis and treatment plan for each case, since this conduct may avoid clinical intercurrences. In addition, if the intercurrences occur, the patient should be advised of how to proceed.

RESUMEN: El objetivo de este estudio fue discutir y analizar si la extrusión de material endodóntico constituye una intercurrencia evitable, discutiendo las implicaciones clínicas, éticas y legales. Paciente LSR, de 31 años de edad, mujer, asistió a una consulta dental quejándose de dolor en el segundo premolar maxilar izquierdo (diente 25). Radiográficamente, se observó un solo conducto radicular y engrosamiento del ligamento periodontal asociado con la extravasación de 8 mm de gutapercha al seno maxilar. La primera sesión de endodoncia tuvo como objetivo realizar la desobturación, la preparación del conducto radicular y la colocación de medicación intracanal. La obturación del conducto radicular se realizó en la segunda sesión. Se llevó a cabo una cirugía apical que extrajo 2 mm del ápice de la raíz y también se realizó el recubrimiento con una membrana de colágeno. Un seguimiento de 22 meses reveló función dental, ausencia de sintomatología dolorosa o infección y ligamento periodontal radiográficamente normal y neoformación ósea. El segundo premolar de una sola raíz es el tipo de premolar con menos distancia con el piso del seno maxilar. En este caso, la extrusión del material obturador se produjo debido a la superinstrumentación del conducto radicular asociada con la proximidad de la raíz con la membrana del seno maxilar. Desde el punto de vista ético y legal, el paciente tiene derecho a ser informado acerca de cualquier inter-ocurrencia que pueda surgir durante o después del tratamiento, y el formulario de consentimiento informado es esencial. Este documento le permitirá al paciente tomar una decisión sobre la realización de un tratamiento de endodoncia en el que el riesgo de un accidente o complicación sea inminente o de que ya se espera un fracaso del tratamiento. Es importante que los profesionales realicen un diagnóstico y un plan de tratamiento adecuados para cada caso, ya que esta conducta puede evitar las intercurrencias clínicas. Además, si se producen intercurrencias, se debe informar al paciente sobre cómo proceder.

Dental Cingulum and Position of Fixed Orthodontic Appliance as Source of Morphological and Therapeutic Identifiers: An Unusual Case Report.

Orthodontic records, such as photographs, radiographs, and dental casts, provide information useful for identification purposes because it may reveal important morphological, therapeutic, and pathological dental identifiers. Among these identifiers, the type and position of orthodontic appliances figure as distinctive tools for human identification. In this context, the present study aims to report an uncommon case of identification of a putrefied body, found near to a forest region in Brazil. The postmortem (PM) examination showed that the victim had part of a fixed orthodontic appliance installed in the maxillary and mandibular dental arches. To identify the body, relatives of the potential victim presented orthodontic examinations containing panoramic radiography and photographs of the orthodontic treatment. The body was identified based on the analysis of the radiographs and photographs that confirmed the presence of the orthodontic appliances observed PM. More specifically, the identification was supported by the analysis of bracket bonding position of the maxillary and mandibular incisors and the presence of distinctive morphological traits of the canines and incisors, as well dental roots observed radiographically. The present case highlights the importance of orthodontic records as a source of morphological dental identifiers for cases in which only unrestored teeth are available.

Case-specific characteristics of pink teeth in dental autopsies - A systematic review.

The cadaveric alterations that derive from the decomposition of the human body are often investigated and examined in medical autopsies together with any other evidence of thanatological interest. This study aimed to systematically review case-specific characteristics of dental autopsies that reported the pink tooth phenomenon (PTP). The review was performed in October/2018 and followed PRISMA and Cochrane guidelines. Seven databases were searched as primary study sources (PubMed, Scopus, LILACS, SciELO, Web of Science, Science Direct and Embase) and three (OATD, Open Grey and Open Thesis) were searched for "grey literature". Only descriptive studies were collected, namely case reports and case series. The risk of bias among the studies was assessed with The Joanna Briggs Institute Critical Appraisal tool. From each case, the sex and age of the victims were registered, together with the place of body recovery, time of death, cadaveric status, cause of death, and number and position of pink teeth. Additionally, a supplemental quantitative analysis was conducted within a sampled subgroup. Poisson regression with robust variance was used to analyze relative risks of presenting pink teeth according to age and tooth position. Eleven studies out of 1004 were eligible. In total 71 cases of cadavers with pink teeth were reported. Two (2.81%) victims had unknown sex, while 17 (23.95%) were females and 52 (73.24%) were males. The victims were aged between 4 and 85 years (mean age 31.13 ±â€¯13.32). Dental autopsies registered 331 pink teeth (163 anterior, 87 premolars and 81 molars). The age did not influence on presenting an additional pink tooth, regardless of tooth position (p > 0.05). Forensic dentists must be aware of pink teeth in dental autopsies. This is an unspecific phenomenon and must not be misinterpreted in medico-legal investigations.

Extractions in Patients with Periodontal Diseases and Clinical Decision-Making Process.

OBJECTIVES: To investigate the professional aspects and clinical and radiographic evidence that influences the decision for the extraction of teeth among periodontologists and general dentists. MATERIAL AND METHODS: The sample consisted of 150 (n=106 females and 44 males) dentists (n=103 general dentists and 47 periodontologists) that responded to a questionnaire designed to retrieve cross-sectional information related mainly to their level of training and time of experience in practice, as well as their personal decision for managing four patients with periodontal disease. Bivariate analyses were performed to test the association between the clinical decisions and the professional information collected from the dentists. RESULTS: In specific cases, periodontologists decided to maintain more teeth than general dentists (p<0.05). In other cases, dentists with more years of experience in practice decided to opt for more extractions (p<0.05). The level of periodontal disease (50-92%), poor oral hygiene (42.6-67.3%) and lack of alveolar bone structure (43.2-79.3%) were the most prevalent reasons behind the decision for extractions. CONCLUSIONS: An advanced level of training in Dentistry, especially Periodontology, and more years of experience in practice may lead to more well-founded decisions on whether extracting teeth or not in case-specific scenarios.

Morphology of the palate, palatal rugae pattern, and dental arch form in patients with schizophrenia.

AIMS: This study aimed to investigate the morphology of the palate, palatal rugae pattern, and dental arch form in patients with schizophrenia. METHODS AND RESULTS: An observational case-control study was designed following the STROBE statement and checklist. The sample consisted of 132 patients (39 diagnosed with schizophrenia and 93 controls). Dental casts of the patients were classified based on the pattern of their palatal rugae, their dental arch form, and the area of their palate. The palatal rugae in patients with schizophrenia had a more random distribution and shape compared to the control group (P = .027). Oval dental arches were the most prevalent in both groups (P = .473). The palate area was slightly larger in the control group (3.2318 ± 0.549 mm2 ) compared with the group of patients with schizophrenia (3.060 ± 0.470 mm2 ) (P = .090). CONCLUSION: Palatal rugae pattern may feature as a potential minor physical anomaly for schizophrenia. Additional studies with alternative sampling and classification systems are necessary to understand this finding and its applications in practice.
