ABSTRACT Objective: To evaluate scientific production on disabled persons with dental care needs over a 20-year period. Material and Methods: The search was conducted in the PubMed database using the MeSH terms “Disabled Persons” AND “Dentistry”. Three researchers selected articles based on readings of the title, abstract and full text. The articles were categorized according to periodical, country, study design, subject and classification of comorbidities and associated disorders. Three hundred ninety-seven articles published in 140 periodicals were included. Results: The periodicals Special Care in Dentistry (54), Dental Clinics of North America (14) and British Dental Journal (14) accounted for 21% of the publications. The studies were conducted in 50 countries, with the United States accounting for 33%. More than half (52%) of the studies had a cross-sectional design. The main subject addressed was oral diagnosis and most of the comorbidities were generalized disabilities. Conclusion: Although a large number of the periodicals have contributed to knowledge building on disabled persons with dental care needs, the number of articles is small compared to other fields of dentistry. Moreover, important gaps in knowledge persist and projects with better methodological designs are needed to offer a more substantial contribution to clinical practice.

Abstract The aim of this study was to investigate the intraoral distribution of untreated caries and tooth loss and estimate the impact of different socioeconomic factors on the occurrence of these outcomes. A cross-sectional study was conducted with 652 18-year-old male adolescents from the city of Sapucaia do Sul, Brazil, who conscripted for military service. The participants answered a questionnaire addressing sociodemographic variables. Two trained and calibrated examiners performed the clinical examinations for the diagnosis of dental caries using the criteria of the World Health Organization. Tooth group and adolescent were the units of analysis for the primary outcomes of the study. Poisson regression analysis with robust variance was performed, with the calculation of crude and adjusted prevalence ratios (PR) and 95% confidence intervals (CI). The prevalence of caries experience and untreated caries was 70.2% and 39.3%, respectively, and 9.4% of the adolescents had missing teeth. Sixty-seven percent of the untreated caries and 98.8% of missing teeth were in first molars. The probability of dental caries and tooth loss was significantly higher among adolescents with less schooling (PR = 2.56; 95%CI: 1.97–3.32 and PR = 3.28; 95%CI: 1.61–6.65, respectively) and those whose mothers had less schooling (PR = 1.31; 95%CI: 1.03–1.67 and PR = 2.30; 95%CI: 1.18–4.50, respectively). In conclusion, the occurrence of untreated dental caries and tooth loss was concentrated in the first molars of adolescents. Moreover, the prevalence of both conditions was higher among adolescents with low schooling and whose mothers had low schooling, reflecting the strong intraoral and socioeconomic polarization of these outcomes.

Abstract The most recent Severe Acute Respiratory Syndrome - COVID-19 - caused by coronavirus infection (SARS-CoV-2) has high-virulence transmission and direct human contagiousness by proximity. Thus, the considerable occupational risk in pediatric dentistry is evident, given the nature and form of procedures performed in an outpatient setting. Thus, the aim of this paper was to identify and contextualize technical and scientific information available to date aimed at preventing and minimizing risks for patients, caregivers and professionals. The results indicate that protective measures are being developed considering procedures according to risks and benefits, and five points stand out: 1. Regulation of resumption of elective procedures, screening and scheduling patients; 2. Restructuring clinical environment and infection control; 3. Improvement of personal protective equipment and biosafety recommendations; 4. Maximization of the use of non-invasive techniques, use of high-powered dental suction, and absolute isolation of the operative field; and 5. Minimization of the use of air-water syringe, dental spittoon and high-speed handpiece. The measures to be taken require reflection for the restart of a “new clinical practice”, especially aiming at behavioral and structural changes regarding operational biosafety.

A ocorrência de hipodontia - ausência de dentes - e hiperdontia - presença de dentes a mais - em um mesmo paciente é uma condição pouco freqüente na clínica odontológica. O diagnóstico precoce e a realização de um tratamento adequado são muito importantes para a abordagem deste tipo de anomalia na dentição mista. A abordagem dependerá da complexidade de cada caso e do momento de diagnóstico da condição. Nesse artigo é relatado um caso de uma paciente com 11 anos de idade com a ausência dos incisivos laterais permanentes superiores e dos segundos pré-molares inferiores, concomitante com a presença de um dente supranumerário na região de incisivo lateral superior direito. Com base no exame físico e radiográfico chegou-se ao diagnóstico de hipo-hiperdontia. As condutas para o diagnóstico e tratamento do caso são abordadas e discutidas. O tratamento adotado foi a remoção do dente supranumerário e a transformação estética dos caninos permanentes superiores em incisivos laterais.

The occurrence of hypodontia (absence of teeth) and hyperdontia (presence of supernumerary teeth) in the same patient is a rarely seen condition in dental practice. Early diagnosis and adequate treatment are very important when addressing this abnormality in the mixed dentition. The approach will depend on the severity of the case and the timing of diagnosis. This paper reports the case of an 11-year-old patient with absence of the permanent maxillary lateral incisors and the mandibular second premolars, with concomitant presence of a supernumerary tooth in the region of the right mandibular lateral incisor. Based on physical and radiographic examination findings, a diagnosis of hypo-hyperdontia was made. The diagnostic and therapeutic management of the case is discussed. The treatment adopted was surgical removal of the supernumerary teeth and esthetic restoration to transform the permanent mandibular canines into lateral incisors.

O objetivo deste estudo foi verificar a utilização de serviços odontológicos e idade da primeira visita odontológica em pré-escolares do Município de Canela, Rio Grande do Sul, Brasil. Um levantamento epidemiológico em crianças menores de cinco anos de idade foi realizado durante a Campanha Nacional de Multivacinação Infantil no município. Um questionário contendo informações a respeito da idade da primeira consulta odontológica e características demográficas da criança foi respondido pelos responsáveis. Os dados foram analisados utilizando-se modelo de regressão logística. Um total de 1.092 crianças foram examinadas. Do total da amostra, 13,3% já haviam consultado o cirurgião-dentista, e somente 4,3% realizaram algum tipo de consulta odontológica até o primeiro ano de vida. O número de crianças que já haviam recebido atendimento odontológico aumentou com a idade. Crianças do sexo feminino apresentaram maior chance de ter recebido atendimento odontológico do que as do sexo masculino (OR = 1,46; IC95%: 1,01-2,1). Conclui-se que é necessário o estabelecimento de políticas públicas de promoção de saúde e reorientação de serviços que facilitem a utilização dos serviços odontológicos e possibilitem o atendimento às crianças de pouca idade.

The aim of this study was to assess the use of dental services and age at first dental visit in preschool children in Canela, Rio Grande do Sul State, Brazil. A representative sample of under-five children was surveyed on National Children's Vaccination Day. Children's parents completed questionnaires containing socio-demographic data and age at first dental visit. Data were analyzed using multiple logistic regression. 192 children were examined. 13.3% of the sample had already visited the dentist at least once, but only 4.3% had their first dental visit by one year of age. The number of children who had already visited a dentist increased with age. Girls showed higher odds of having visited a dentist (OR = 1.46; 95%CI: 1.01-2.1). Public health strategies are needed to determine the effectiveness of health promotion and improve the use of dental services by preschool children.

Este trabalho realizou uma comparação entre três métodos distintos para avaliação da atividade cariosa em âmbito coletivo. Os métodos estudados foram baseados em um CPOS/ceos modificado, com inclusão de lesões não cavitadas. Os fatores estudados foram a possibilidade de reprodutibilidade da inclusão de critérios de atividade cariosa, bem como a presença de placa bacteriana. Portanto, os três grupos avaliados apresentavam-se com placa bacteriana; com remoção de placa bacteriana pelo próprio paciente (sob supervisão) com escova dental e sem placa bacteriana, após profilaxia profissional, que correspondiam aos três métodos de diagnóstico. Os três exames foram realizados com intervalo de uma semana entre cada um. Para esta análise, propõe-se um índice CPOS/ceos modificado com alterações nos critérios de diagnóstico através da inclusão de parâmetros de atividade de doença. O estudo foi realizado em um grupo de 30 crianças, com idade de 11 anos. De acordo com os resultados obtidos, os três métodos de diagnóstico de atividade cariosa, na população estudada, demonstraram-se reproduzíveis, podendo ser mais uma forma de adequadamente realizar-se diagnóstico de cárie em nível coletivo.

The present research has made a comparison between three distinct methods to evaluate carious activity in a community basis. The studied method was based in a modified DMFS/dmfs index including non-cavitated lesions. Two factors were analyzed: the possible reproduction of the inclusion of carious activity criteria and the presence of bacterial plaque. Thus, the three study groups presented with plaque, after supervised self-performed plaque removal with dental toothbrush and without plaque after professional prophylaxis, which corresponded to three diagnostic methods. The three exams took place one week apart from each other. For this analysis, a modified DMFS/dmfs index was proposed with alterations in diagnostic criteria due to the inclusion of carious activity parameters. The study was performed in a group of 30 children aged 11 years old. According to the results, the diagnostic method for carious activity in the three situations was reproducible and can be considered a proper approach to perform caries diagnosis in a community basis.

A técnica do condicionamento ácido e o desenvolvimento e aprimoramento de novos materiais restauradores com características adesivas têm levado a mudanças importantes nas concepções e nos princípios da dentística operatória e restauradora. O objetivo deste estudo foi avaliar a microinfiltração marginal em cavidades proximais de molares decíduos restaurados com cimento de ionômero de vidro modificado por resina (Vitremer, 3M) comparando duas diferentes técnicas: a técnica convencional (conforme recomendações do fabricante) e a técnica de hibridização (ácido fosfórico-37% e sistema adesivo Scotchbond Multi-Uso, 3M ). Foram utilizados 20 molares decíduos hígidos, onde foram preparadas cavidades proximais. A amostra foi dividida aleatoriamente em 2 grupos. No grupo 1 foi utilizado a técnica convencional e no grupo 2 a técnica com condicionamento ácido e aplicação de sistema adesivo. Os dentes foram submetidos ao processo de ciclagem térmica, impermeabilizados, mantendo uma área de 2mm² na margem cervical da restauração e imersos em solução de azul de metileno a 0,5%, por 72 horas. A seguir, foram seccionados e avaliados por um único examinador, que estabeleceu o grau de microinfiltração. Os dados obtidos revelaram que as duas técnicas utilizadas apresentaram microinfiltração marginal em diferentes graus, e que não houve diferença estatisticamente significante entre elas.

This study evaluate the marginal microleakage in deciduous molars cavities restored with ionomer cement modified by resin (Vitremer, 3 M) comparing two different techniques: the conventional (according to manufacturer instructions) and with the hybridization technique (acid phosphoric 37% and adhesive system Scotchbond Multi Pourpose , 3M). Proximal cavities were prepared in 20 sound deciduous molars, right after extraction. The samples were randomly divided in two groups. Group 1 consisted in teeth prepared with the conventional technique and in the group 2 teeth with etching by phosphoric acid and adhesive system. The teeth were submitted to termical cycle process (100 cycles, each one of 3 sub cycles of 5o C, 37o C and 55o C - by 60 Sec of bath immersion each one), after restorations. After that, the teeth were impermeable with nail polish and wax #7 keeping 2mm of area in the junction of the cervical restoration margin, and them immersed in methylen blue solution to 0,5% , seccionated and evaluated by one examiner, who established the microleakage degree. The data reveal the both techniques show the micro infiltration in different degree, but it has no statistical difference between techniques.
