Abstract Objective To examine the emerging evidence on developmental disability type and frequency in the population affected by COVID-19, identifying more frequent forms of categorization, incidence/prevalence and comorbidities. Methods For this scoping review, we searched for observational studies in the MEDLINE (PubMed), Scopus (Elsevier), ISI Web of Science (Clarivate), LILACS (VHL) and grey literature databases. As eligibility criteria, studies should present results of developmental disability (DD) occurrence in people with COVID-19, allowing comparison with the general population, or between groups of disabilities. Two independent reviewers mapped the information using a previously elaborated data extraction instrument. Two other researchers verified the data and assisted in table elaboration to present the results. Results There was a diversity of terminologies used to categorize DD. People with DD and comorbidities that represent a higher risk for COVID-19 required hospitalization more frequently than the general population. Out of a total of 4930 studies, 14 were selected for assessment. Of these, 5 articles were longitudinal studies. Conclusion In people with DD, COVID-19 had higher morbidity, lethality and mortality rates in younger age groups, in the poorest population, in the institutionalized population, requiring life support technologies and specialized care. The vulnerability of people with DD to COVID-19 depends on disease type and severity and the presence of comorbidities, highlighting the need for attention in diagnosis and preventive measures, such as vaccination.

Abstract This study investigated the factors associated with new carious lesions in one-to five-year-old children with developmental disabilities. This was a retrospective cohort that evaluated 64 dental charts of individuals with caries or fillings in their first dental appointment. The dependent variable was the occurrence of a new carious lesion or restoration. Gender, age, mother’s education, sugar consumption, oral hygiene, mouth breathing, reports of xerostomia, gingival status, use of psychotropic drugs, use of asthma drugs, history of asthma, bronchitis, reflux or seizures and having at least one sibling were covariates. Cox proportional hazards regression model was used to estimate the raw and adjusted hazard ratios with their respective 95% confidence interval. The average time that individuals remained free of dental caries/restoration was 79.49 months (95%CI: 64.37 to 92.61). Increase in sucrose consumption increased the rate of caries recurrence (HR = 1.16; 95%CI: 1.04 to 1.30). Individuals who had poor oral hygiene had higher rate of new dental caries (HR = 3.88; 95%CI: 1.22 to 12.37) compared to those with good oral hygiene. The presence of mouth breathing decreased the rate of recurrence of the disease when compared to the nasal breathing (HR = 0.32; 95%CI: 0.15 to 0.70). Oral health-related behaviors and nasal respiration influenced the rate of dental caries recurrence in individuals with developmental disabilities.

Abstract The aim of this study was to assess the factors associated with dental pain in adolescents from the state of Minas Gerais, Brazil. Individual data on adolescents aged 15 to 19 years were collected from the SB Minas survey secondary database. Dental pain over the past 6 months, assessed by a questionnaire, was used as the dependent variable. Sex, income, skin color, prevalence of untreated dental caries, periodontal health, dental treatment needs, and time of last dental appointment were analyzed as individual covariates. Allocation factor, Human Development Index (HDI), Gini coefficient, illiteracy rate, unemployment, 50% and 25% of the Brazilian monthly minimum wage, primary healthcare coverage, oral health team coverage, access to individual healthcare, and supervised toothbrushing average rate were the analyzed contextual variables. A multilevel analysis was conducted for the individual and contextual variables. Statistical analyses used hierarchical linear and nonlinear modeling to infer an association between the different levels. Male adolescents had a lower prevalence of dental pain (OR = 0.53; 95%CI = 0.37–0.75). There was an association between dental pain and low income (OR = 1.58; 95%CI = 1.07–2.33), prevalence of untreated dental caries (OR = 1.25; 95%CI = 1.11–1.40), periodontal health (OR = 1.80; 95%CI = 1.04–3.09), and dental treatment needs (OR = 6.93; 95%CI = 3.96–12.14). Sociodemographic and clinical factors at the individual level were associated with the outcome but not with contextual variables. These findings reinforce the need to address these factors for effective community health actions.

ABSTRACT Objective: To describe dental findings of kidney and liver, pre and post-transplant patients of an oral health care service from a Brazilian Southeast state. Material and Methods: A descriptive cross-sectional study was developed with a sample of patients attending the oral health care program for transplantation of Universidade Federal de Minas Gerais. Participants were divided into two groups according to the kind of transplantation-kidney or liver. Characteristics of the sample, sex (male/female), age (18-44; 45-54; 55-80), living region (Belo Horizonte, or outside), phase of transplantation (pre-Tx or post-Tx), and self-report of diabetes mellitus and hypertension were presented by frequencies. Dental caries experienced was measured by Decayed, Missing and Filled-Teeth (DMF-T) index. Results: 185 patients, kidney (46; 24.9%), and liver (139; 75.1%) were included. Mean DMFT was 18.3 (20.0). DMFT scores of males (18.7; 20.0), females (17.2; 18.0), pre-transplanted (18.3; 20.0), and post-transplanted (18.1; 20.0) were similar. The liver transplantation group (19.3; 20.0) showed higher caries experience comparing to kidney´s (15.2; 17.0). Conclusion: Dental caries experience was high in kidney and liver patients under transplantation therapy. This highlights the demand for treatment need in this population.

Abstract The objective of this study was to describe dental prescriptions of non-steroidal anti-inflammatory drugs (NSAID), opioids, and analgesics dispensed by the Brazilian National Health System (BNHS, SUS in Portuguese) of a Southeastern state from January to December 2017, and to analyze their association with socioeconomic and oral health care services’ characteristics at municipal level. Data were collected from the Brazilian Integrated Pharmaceutical Care Management System. Medicines were grouped according to the Anatomical Therapeutic Chemical Classification System. The total number of Defined Daily Doses (DDD) and DDD per 1,000 inhabitants (inhab.) per year were presented and compared between groups of municipalities. Data analysis used the Classification and Regression Tree model performed with IBM SPSS 25.0. The total number of NSAID, opioids, and analgesics prescriptions was 70,747 and accounted for 354,221.13 DDD. The most frequently prescribed medicine was ibuprofen (n = 24,676; 34.88%). The number of dental practitioners in the BNHS per 1,000 inhab. (p < 0.001), first dental appointment coverage (p = 0.010), oral health teams per 1,000 inhab. (p=0.022), and the proportion of rural population (p = 0.014) were variables positively associated with the number of DDD of NSAID per 1,000 inhab. per year. Bolsa Família program coverage per 1,000 inhab. (p = 0.022) was negatively associated with NSAID prescription. Regarding analgesics, first dental appointment coverage (p=0.002) and Bolsa Família program coverage per 1,000 inhab. (p = 0.012) were positively associated with DDD per 1,000 inhab. per year. In conclusion, dental prescriptions of analgesics and NSAID in the BNHS were associated with socioeconomic and oral health care services’ characteristics.

Abstract Objective: To describe and analyze the availability and factors related to the presence of analgesics and non-steroidal anti-inflammatory drugs in the Brazilian public primary healthcare system. Material and Methods: This was a cross-sectional study that evaluated 17,903 health units that participated in the National Program for Primary Care Access and Quality Improvement (2013-2014). The dependent variable was defined as the presence of metamizole, ibuprofen, and acetaminophen in a sufficient amount. The independent variables included the type of primary health care unit, the presence of a medication disposal area, the number of physicians, nurses, and dental practitioners; and the number of primary care units with family and oral health teams. For statistical analysis, unadjusted and adjusted Odds Ratio (OR) (95% CI) were presented. Results: The three medicines were available in 62.4% of the units. Regarding Health Clinics, the Basic Health Units (OR= 1.31, CI95% 1.18-1.44), Polyclinic (OR= 2.00, 95% CI, 1.15 -3.48), and others (OR= 1.37; 95% CI 1.14-1.63) had higher chances of availability of all three drugs. The presence of a disposal area (OR = 1.64, 95% CI 1.51-1.77) and the number of physicians (OR= 1.04, 95% CI 1.00-1.08), nurses (OR= 1.08, 95% CI 1.03- 1.13), and dental practitioners (OR= 1.09, 95% CI 1.04-1.14) increased the availability odds of the analyzed drugs in the service. Conclusion: The structure of the healthcare units and the higher number of professionals were positively associated with the availability of these drugs.

Resumo Introdução O uso de psicotrópicos por cirurgiões-dentistas é permitido por lei no Brasil para casos clínicos específicos. São poucos os estudos sobre a sua utilização na odontologia. Objetivo Este estudo investigou a prescrição de psicotrópicos por cirurgiões-dentistas inscritos no Conselho Regional de Minas Gerais e seu conhecimento sobre a Portaria 344/1998. Método Foram enviados aos 15.250 cirurgiões-dentistas um questionário eletrônico com 13 questões abordando a prescrição de psicotrópicos, e foram respondidos 969 questionários. Foram estudados: o tempo de formado, tipo de instituição de graduação, tipo de pós-graduação, medicamentos mais prescritos, conhecimento sobre a Portaria 344/1998 e público mais frequente que recebe a prescrição. Resultados 257 profissionais prescrevem psicotrópicos e 223 conhecem a legislação. Um preocupante percentual de profissionais que prescreve esses medicamentos não conhece o teor da Portaria 344/1998. Os analgésicos opioides são os medicamentos mais prescritos. Os especialistas são os que mais prescrevem psicotrópicos (p=0,015), e aqueles que prescrevem ansiolíticos conhecem a legislação com maior frequência (p=0,003). Os cirurgiões bucomaxilofaciais (p=0,02) e os especialistas em distúrbios da articulação temporomandibular (0,03) são os que mais conhecem a legislação e prescrevem medicação psicotrópica. A dor forte e o medo são as duas principais razões para a prescrição. Conclusão Ser especialista e conhecer a Portaria 344/1998 são fatores associados à prescrição de psicotrópicos entre cirurgiões-dentistas.

Abstract Background The use of psychotropics by dental surgeons is permitted by law in Brazil for specific clinical cases. There are few studies on its use in dentistry. Objective This study investigated the prescription of psychotropics drugs by dentists enrolled in the Regional Council of Minas Gerais and their knowledge about regulatory ordinance 344/1998. Method An electronic questionnaire with 13 questions addressing the prescription of psychotropic drugs was sent to 15250 dental surgeons and 969 questionnaires were answered. It was considered the time of graduation, type of undergraduate institution, type of postgraduate course, more frequent prescribed medication, knowledge about ordinance 344/1998 and more frequent public that receives the prescription. Results Two hundred and fifty-seven professionals prescribe psychotropic drugs and 223 know the law, and a worrying percentage of professionals who prescribe these drugs does not know the content of the Ordinance 344/1998. Opioid analgesics are the most prescribed psychotropic medications. Specialists are the ones who prescribe psychotropic drugs (p=0.015) and those professionals who prescribe anxiolytics know the legislation more frequently (p=0.003). The maxillofacial surgeons (p=0.02) and experts in disorders of the temporomandibular jaw joint (0.03) are the ones who know the law and prescribe psychotropic medication. Strong pain and fear are the two main reasons for prescribing psychotropic drugs. Conclusion Being a specialist and knowing the ordinance 344/1998 are factors associated with the prescription of psychotropic medications among dentists.

Abstract This study investigated risk factors for tooth injuries in individuals from a dental clinical reference service for patients with special needs in Belo Horizonte, MG, Brazil. This is a retrospective cohort study that evaluated 493 dental charts of individuals with or without tooth injuries at their first dental appointment. The dependent variable was the time of occurrence of new dental traumatic injuries and was measured in months. Gender, age, International Code of Diseases, mother’s education, mouth breathing, hyperkinesis, pacifier use, thumb sucking, psychotropic drug use, tooth injuries at the first dental examination, involuntary movements, open bite, having one or more siblings and reports of seizures were the covariates. The Cox proportional hazards regression model was used to estimate the unadjusted and adjusted hazard ratios and their respective 95% confidence intervals. The average time that individuals remained free of dental traumatism was 170.78 months (95% CI, 157.89-183.66) with median of 216 months. The incidence of new events was 11.88%. The covariate associated with an increased risk of dental traumatism was a history of tooth injuries at the first dental appointment. The increase in dental trauma risk was 3.59 (95% CI, 1.94-6.65). A history of traumatic dental injury was the risk factor for the dental trauma found in this group of individuals with developmental disabilities.

RESUMO O transplante de fígado é o tratamento de escolha para o estágio final da doença hepática e oferece a possibilidade ao paciente de retorno a uma vida ativa e longa. Uma avaliação dentária antes do transplante é recomendada como pre-requisito para a eliminação de infecções orais, as quais podem piorar o quadro do paciente. Este relato de caso se refere a uma fratura radicular de dente anterior em um paciente em tratamento odontológico prévio ao transplante de fígado. No exame clínico, o incisivo central superior direito (11) apresentava-se sem alteração na coloração mas com mobilidade no sentido vestíbulo-lingual, ligeira vestibularização e extrusão, e fístula na gengiva inserida na distal do 11. O paciente relatou ter sofrido traumatismo na região há mais de 30 anos. Ao exame radiográfico, foi identificada uma linha de fratura radicular horizontal no terço médio, associada à lesão óssea indicada por uma área radiolúcida na superfície distal do 11. O tratamento proposto para o caso envolveu procedimentos de raspagem e alisamento subgengival da superfície distal, o tratamento endodôntico radical da porção coronária radicular com posterior obturação com Agregado Trióxido Mineral e imobilização dental. O acompanhamento clínico e radiográfico, em intervalos de três meses, permitiu observar a regressão gradual da lesão, com formação de osso no local, contribuindo para manutenção do quadro de saúde geral e emocional do paciente, preservando seu sorriso e sua qualidade de vida.

ABSTRACT Liver transplantation is the treatment of choice for end-stage liver disease patients, and offers them the possibility of returning to active and longer life. A dental evaluation before transplantation is a recommended prerequisite to avoid oral infections, which can worsen the patient’s overall situation. This case report refers to the root fracture of an anterior tooth in a patient who was undergoing dental treatment prior to liver transplantation. On clinical examination, the maxillary right central incisor (11) presented without color change, but with mobility in the buccolingual direction, slight flaring and extrusion, and fistula in the attached gingiva on the distal side of tooth 11. The patient reported that he had suffered a trauma in that region 30 years before. The radiographic examination showed a horizontal fracture of the middle third of the root, associated with bone damage, indicated by a radiolucent area at the distal surface of 11. The proposed treatment consisted of: scraping procedure and straightening of the distal surface, radical endodontic treatment of the coronal portion of the root, subsequent filling with Mineral Trioxide Aggregate and dental immobilization. The clinical and radiographic follow-up at three-monthly intervals allowed us to observe gradual regression of the lesion with bone formation, contributing to maintenance of the patient’s general and emotional health, preserving his smile and quality of life.

Abstract The aim of the present study was to investigate risk factors for dental caries in children with developmental disabilities who were treated at a clinical reference service for patients with special needs in Belo Horizonte, MG, Brazil. This is a retrospective cohort study that evaluated 401 dental charts of individuals without dental caries or restorations in their first dental appointment. The dependent variable was the time of occurrence of new dental caries or restorations and was measured in months. Gender, age, International Code of Diseases (ICD), mother´s education, sugar consumption, use of fluoride toothpaste, oral hygiene, mouth breathing, reports of xerostomia, gingival status, use of psychotropic or asthma drugs, and history of asthma were covariates. The Cox proportional hazards regression model was used to estimate the raw and adjusted hazard ratios and their respective 95% confidence intervals. The average time that individuals remained free of dental caries/restoration was equal to 107.46 months (95%CI 95.41 to 119.51), with a median of caries-free children up to 94 months. For each point increase in the scale of sucrose consumption, the increase in caries risk was 1.07 (95%CI 1.01 to 1.15). Sucrose consumption was the only risk factor for dental caries found in this group of individuals with developmental disabilities.

Trata-se de estudo transversal e analítico cujo objetivo foi avaliar a associação entre a prevalência e a gravidade da fluorose e da cárie dentária em municípios rurais com fluorose endêmica no norte do Estado de Minas Gerais, Brasil, com concentração de flúor nas águas de até 4,8 mg/L. Os dados foram coletados por um examinador (Kappa intra examinador, 0,96 para fluorose e 0,95 para cárie) após escovação dentária. Participaram do estudo 511 indivíduos, com idades de 7 a 22 anos, categorizados conforme faixa etária: 7 a 9 anos (n = 227), 10 a 12 anos (n = 153), 13 a 15 anos (n = 92), 16 a 22 anos (n = 39). Para o diagnóstico da cárie dentária, utilizaram-se os critérios da Organização Mundial da Saúde (OMS) para a mensuração do índice de Dentes Cariados, Perdidos e Obturados (CPO-D). Para a fluorose utilizou-se o índice de Thylstrup e Fejerskov (TF), dicotomizado segundo a prevalência (TF = 0 e TF > 0) e gravidade (TF < 4 e TF > 5).Nos dois grupos mais jovens, o CPO-D e seu componente cariado foram maiores no grupo com fluorose mais grave (p < 0,001). Essa associação não foi identificada entre os adolescentes e adultos (p > 0,05). A associação mais grave entre as condições cárie e fluorose foi encontrada em indivíduos com até 12 anos.

It is observational, analytical and cross-sectional aimed to evaluate the association between severity and prevalence of fluorosis and dental caries in rural communities with endemic dental fluorosis in the north state of Minas Gerais, Brazil, with fluoride concentrations in water up to 4.8 mg/L. Data were collected by one examiner (intra-examiner kappa, 0.96 to 0,95 for caries and fluorosis) after toothbrushing. The study included 511 individuals aged 7 - 22 years, categorized according to age: 7 - 9 years (n = 227), 10 to 12 years (n = 153), 13 to 15 years (n = 92), 16 to 22 years (n = 39). For the diagnosis of dental caries used the criteria of the World Health Organization to measure indices DMFT. For fluorosis used the index Thylstrup and Fejerskov (TF), dichotomized according to prevalence (TF = 0 and TF > 0) and severity (TF < 4 and TF > 5). In the two younger groups, the DMFT and its decay component were higher in the group with more severe fluorosis (p < 0.001). This association was not found among adolescents and adults (p > 0.05). The association was found between the conditions more severe fluorosis and caries in individuals under 12 years.

OBJETIVO: Compreender crenças e atitudes em relação à fluorose dentária de jovens residentes em região rural do Brasil. PROCEDIMENTOS METODOLÓGICOS: Estudo qualitativo em que foram realizadas entrevistas semi-estruturadas com 23 adolescentes com fluorose dentária, 14 professores e três gestores públicos no município de São Francisco, MG, em 2002. Foram empregadas a técnica de análise de conteúdo e a teoria das representações sociais. ANÁLISE DOS RESULTADOS: Pelas características organolépticas que imprime à água (sabor salgado, coloração esbranquiçada e turbidez) e sua associação com aspectos negativos relacionados ao uso doméstico, o carbonato é considerado a causa da fluorose por adolescentes e professores. Mesmo após o contato com pesquisadores que investigaram o fenômeno e que participaram da sua solução, a população continua a resistir em aceitar o flúor como causa do problema e não concorda plenamente com o uso de água de outras fontes por duvidar de sua qualidade. CONCLUSÕES: Percepções equivocadas em relação às causas da fluorose dentária e a dificuldade em custear o tratamento da água comprometem a implantação de suprimento de água de superfície não contaminada. Estratégias de educação em saúde devem ser implementadas paralelamente a soluções para captação de água de fontes alternativas não contaminadas em localidades afetadas pela seca.

OBJECTIVE: To understand beliefs and attitudes about fluorosis among young people living in a rural area. METHODOLOGICAL PROCEDURES: Qualitative study consisting of semi-structured interviews with 23 adolescents with dental fluorosis, 14 teachers and three health authorities in the city of São Francisco, Southeastern Brazil, in 2002. Content analysis and social representation theory were applied. ANALYSIS OF RESULTS: The organoleptic characteristics of carbonates that affect groundwater (salty flavor, whitish coloration, and turbidity) associated with negative aspects of household use of this water are considered a cause of mottled enamel. Even after contact with researchers who investigated this phenomenon and helped find a solution for this condition, the local population is still unwilling to accept fluoride as the cause of the problem and does not fully agree to use water from other sources because they are afraid of the quality of water. CONCLUSIONS: Misperceptions of the causes of dental fluorosis and water treatment costs compromise the implementation of uncontaminated surface water supplies. Health education strategies are required in parallel with solutions for securing water supply in drought-ravaged areas.

OBJETIVO: Comprender creencias y actitudes con relación a la fluorosis dentaria de jóvenes residentes en región rural de Brasil. MÉTODOS: Estudio cualitativo en que fueron realizadas entrevistas semi-estructuradas con 23 adolescentes con fluorosis dentaria, 14 profesores y tres gestores públicos en el municipio de Sao Francisco, en Sureste de Brasil, en 2002. Fueron empleadas la técnica de análisis de contenido y la teoría de las representaciones sociales. RESULTADOS: Por las características organolépticas que imprime al agua (sabor salado, coloración blanquecina y turbidez) y su asociación con aspectos negativos relacionados al uso doméstico, el carbonato es considerado la causa de la fluorosis por adolescentes y profesores. Aún posterior al contacto con científicos que investigaron el fenómeno y que participaron de su solución, la población continúa resistiendo en aceptar el flúor como causa del problema y no concuerda plenamente con el uso de agua de otras fuentes por dudar de su calidad. CONCLUSIONES: Percepciones equivocadas con relación a las causas de la fluorosis dentaria y la dificultad en costear el tratamiento del agua comprometen la implantación del suplemento de agua de superficie no contaminada. Estrategias de educación en salud deben ser implementadas paralelamente a soluciones para captación de agua de fuentes alternativas no contaminadas en localidades afectadas por la seca.

Mesmo após o contato com pesquisadores que investigaram o fenômeno e que participaram da sua solução, a população continua a resistir em aceitar o flúor como causa do problema e não concorda plenamente com o uso de água de outras fontes por duvidar de sua qualidade. CONCLUSÕES: Percepções equivocadas em relação às causas da fluorose dentária e a dificuldade em custear o tratamento da água comprometem a implantação de suprimento de água de superfície não contaminada. Estratégias de educação em saúde devem ser implementadas paralelamente a soluções para captação de água de fontes alternativas não contaminadas em localidades afetadas pela seca.

OBJECTIVE: To understand beliefs and attitudes about fluorosis among young people living in a rural area. METHODOLOGICAL PROCEDURES: Qualitative study consisting of semi-structured interviews with 23 adolescents with dental fluorosis, 14 teachers and three health authorities in the city of São Francisco, Southeastern Brazil, in 2002. Content analysis and social representation theory were applied. ANALYSIS OF RESULTS: The organoleptic characteristics of carbonates that affect groundwater (salty flavor, whitish coloration, and turbidity) associated with negative aspects of household use of this water are considered a cause of mottled enamel. Even after contact with researchers who investigated this phenomenon and helped find a solution for this condition, the local population is still unwilling to accept fluoride as the cause of the problem and does not fully agree to use water from other sources because they are afraid of the quality of water. CONCLUSIONS: Misperceptions of the causes of dental fluorosis and water treatment costs compromise the implementation of uncontaminated surface water supplies. Health education strategies are required in parallel with solutions for securing water supply in drought-ravaged areas.

OBJETIVO: Comprender creencias y actitudes con relación a la fluorosis dentaria de jóvenes residentes en región rural de Brasil. MÉTODOS: Estudio cualitativo en que fueron realizadas entrevistas semi-estructuradas con 23 adolescentes con fluorosis dentaria, 14 profesores y tres gestores públicos en el municipio de Sao Francisco, en Sureste de Brasil, en 2002. Fueron empleadas la técnica de análisis de contenido y la teoría de las representaciones sociales. RESULTADOS: Por las características organolépticas que imprime al agua (sabor salado, coloración blanquecina y turbidez) y su asociación con aspectos negativos relacionados al uso doméstico, el carbonato es considerado la causa de la fluorosis por adolescentes y profesores. Aún posterior al contacto con científicos que investigaron el fenómeno y que participaron de su solución, la población continúa resistiendo en aceptar el flúor como causa del problema y no concuerda plenamente con el uso de agua de otras fuentes por dudar de su calidad. CONCLUSIONES: Percepciones equivocadas con relación a las causas de la fluorosis dentaria y la dificultad en costear el tratamiento del agua comprometen la implantación del suplemento de agua de superficie no contaminada. Estrategias de educación en salud deben ser implementadas paralelamente a soluciones para captación de agua de fuentes alternativas no contaminadas en localidades afectadas por la seca.

Todas as pessoas envolvidas em um atendimento odontológico estão sujeitas à contaminação por bactérias, vírus e fungos que podem causar diversas enfermidades, dentre as quais se destacam a hepatite, a tuberculose, o herpes e a AIDS. Sabe-se que, durante um atendimento, há possibilidade de ocorrer dispersão de respingos e aerossóis contendo microrganismos patogênicos. No entanto, algumas clínicas odontológicas são projetadas com vários consultórios no mesmo ambiente, sem divisórias entre eles. O objetivo deste trabalho foi verificar qual o alcance dos respingos provenientes da utilização de seringa tríplice e turbina de alta rotação em cinco atendimentos clínicos simulados em uma clínica de atendimento coletivo, considerando que estes respingos podem conter saliva e sangue do paciente. Para isso, anilina de diferentes cores (rosa, azul, amarela, verde e marrom) foi adicionada à água do reservatório de cada um dos cinco equipamentos. Todo o ambiente físico, assim como a roupa do operador e do paciente, foram cobertos com papel crepom branco. Constatou-se grande concentração de respingos sobre as cadeiras, sobre o operador, sobre o piso, cadeiras vizinhas e bandejas clínicas das unidades vizinhas. A distância máxima atingida pelos respingos foi de 1,82 m, medindo-se a partir do ponto correspondente à boca do paciente. Durante um atendimento real, coletivo e simultâneo nesta clínica, as cadeiras vizinhas e seus respectivos pacientes e operadores, bem como as bandejas clínicas contendo instrumental esterilizado situam-se dentro da área de abrangência dos respingos. Portanto, existe uma possibilidade real de ocorrer contaminação cruzada, havendo necessidade de colocação de barreiras físicas entre os equipamentos. O estudo evidenciou também a necessidade de proteção de toda a face, o corpo, o cabelo e os braços do operador, uma vez que estas foram regiões muito atingidas pelos respingos.

The professionals and patients involved in dental examinations are at risk for infection by various disease-causing bacteria, viruses, and fungi, such as those responsible for hepatitis, tuberculosis, herpes, and AIDS. It is known that aerosols and spatter containing pathogenic microorganisms can spread during an examination. Nevertheless, some dental clinics are designed to have multiple examination areas in the same room, with no physical barriers between them. The objective of this study was to verify the reach of spatter resulting from the use of a triple syringe and high-rotation turbine during five simulated exams in a collective clinic, bearing in mind that spatter can contain the patient's saliva and blood. To facilitate tracking of the spatter, aniline dye (pink, blue, yellow, green, and brown) was added to the water in the appropriate receptacle in each of the five units. The room, the equipment, and the patient's and operator's clothing were covered with white paper. A high concentration of spatter was observed on the chair, the operator, and the floor of each unit, and it also appeared on the chairs and trays of the surrounding units. The maximum distance reached by spatter was 1.82 m from a point on the chair corresponding to the position of the patient's mouth. During real simultaneous examinations, the surrounding chairs and their patients and operators, as well as the trays containing sterilized instruments, are within spatter range. Therefore, there is a real possibility of cross-infection, and physical barriers should be placed between the units. This study also confirmed the need for protection of the operator's face, body, hair, and arms, since these regions were heavily affected by spatter.
