<strong>Introdução:</strong> A Hipomineralização Molar-Incisivo (HMI) é um defeito de desenvolvimento do esmalte dentário que afeta de um até todos os primeiros molares permanentes, podendo estar presente nos incisivos permanentes. <strong>Objetivo:</strong> Revisar a literatura sobre a HMI objetivando proporcionar informações ao cirurgião-dentista que realiza atendimento infantil sobre o diagnóstico, características clínicas e tratamento. <strong>Metodologia:</strong> Revisão integrativa da literatura, sendo utilizado as bases de dados LILACS, PubMed, Web of Science e Scopus. Foram usadas as palavras-chaves "Hipoplasia do Esmalte Dentário/Dental Enamel Hypoplasia" e " Hipomineralização Molar-Incisivo/Molar Incisor Hypomineralization". <strong>Resultados:</strong> Fatores etiológicos associados a complicações pré, peri e pós-natais, ambientais e genéticos têm sido evidenciados e a prevalência de HMI mostra-se variada entre as populações. Apresenta-se como manchas opacas bem delimitadas e, com o aumento da gravidade, ocorre a perda do esmalte resultando em fratura, destruição coronária e indicação de exodontia. As fraturas pós-eruptivas atuam como áreas de retenção de biofilme, o que facilita seu acúmulo e aumenta a susceptibilidade à cárie dentária. A Academia Europeia de Odontopediatria (EAPD) estabeleceu critérios que facilitam o diagnóstico deste agravo por meio de pesquisas epidemiológicas. As medidas terapêuticas são direcionadas de acordo com a gravidade da lesão. <strong>Conclusão:</strong> A HMI deve receber adequada atenção do cirurgião-dentista em função das consequências clínicas e estéticas que acarreta ao paciente, interferindo negativamente na sua qualidade de vida nos casos mais graves. Novas pesquisas são necessárias com a finalidade de expandir o conhecimento acerca da HMI, objetivando ofertar ao paciente o correto diagnóstico e a melhor opção terapêutica.

Introdução: Os Sistemas de informação têm como finalidade promover a elaboração e facilitar a avaliação de políticas, planos e programas de saúde, uma vez que seus indicadores refletem a saúde da população. Objetivo: O presente estudo tem como objetivo caracterizar o modelo de atenção básica à saúde bucal na região Nordeste do Brasil, a partir de dados secundários da produção ambulatorial em saúde bucal, disponíveis no SIA-SUS. Material e método: Tratou-se de estudo descritivo e quantitativo, utilizando dados secundários a partir da produção ambulatorial da atenção básica em saúde bucal, disponíveis no Sistema de Informações Ambulatoriais do Sistema Único de Saúde (SIA-SUS). A coleta dos dados foi feita a partir do banco de dados do Departamento de Informática do SUS (DATASUS) e considerou o período de janeiro de 2015 a dezembro de 2017. Foram incluídos no estudo os dados sobre os procedimentos curativos e preventivos realizados em ambiente ambulatorial pelos cirurgiões-dentistas. Os dados foram apresentados por meio de estatística descritiva. Resultados: Obteve-se em 2015, o maior número total de procedimentos realizados (52.801.784). Do total de procedimentos curativos entre 2015-2017, tem-se maioria de procedimentos restauradores (22,7%) e minoria de procedimentos cirúrgicos (15,2%). Observa-se que, nos três anos estudados, a produção de procedimentos curativos superou a de procedimentos preventivos.

The aim of this study was to investigate the prevalence of dental fear and to evaluate its association with dental caries and molar incisor hypomineralization (MIH) in schoolchildren aged 8-10 years from a municipality in Northeastern Brazil. Data from 466 students enrolled in urban public schools in a cross-sectional study were collected. Parents/guardians answered a questionnaire addressing sociodemographic characteristics, dental fear was measured by means of the Children’s Fear Survey Schedule-Dental Subscale (CFSS-DS) and clinical examinations were performed by three calibrated examiners for diagnosis of dental caries, using the International Caries Detection & Assessment System - ICDAS II and a previously validated index for MIH. Descriptive data analysis was performed, and associations between dental fear, dental caries and MIH were analyzed using robust Poisson regression for complex samples (p<0,05). The prevalence of dental fear was 21.6%, and the mean total CFSS-DS score was 29.97 (CI 95%=29.05-30.89). In the multivariate adjusted model, the prevalence of dental fear was associated to family income (PR=1.78; CI 95%=1.02-3.08; p= 0.041). Monthly family income was associated with dental fear in children, whereas dental caries and MIH were not associated with dental fear.

To estimate the prevalence of dental fear in schoolchildren and verify its association with gender, age group and oral health habits. Cross-sectional study with 44 elementary students from public schools. Data on sociodemographic issues and children's oral health habits were collected and the Children’s Fear Survey Schedule - Dental Subscale (CFSS-DS) questionnaire was applied. Descriptive analysis of the data was performed, Fisher's Exact and U Mann-Whitney tests (p <0.05). The prevalence of dental fear was 6.8% and the average of the total score of the CFSS-DS was 26.43 ± 7.20, median of 24.50, IQR25-75 21-33, minimum score of 16 and a maximum of 42. Most children had a low level of dental fear (95.5%). The levels of dental fear did not show statistically significant associations between sex (p = 0.162), age group (p = 0.181), having visited the dentist once in life (p = 0.201), complaints of tooth pain (p = 0.522) and complaints of tooth sensitivity (p = 0.181). The prevalence of dental fear was low and most children had a low level of dental fear. There was no association between dental fear and the variables sex, age, having visited the dentist at any time in life, complaints of pain and complaints of dental sensitivity.

Background: The coronavirus disease 2019 pandemic (COVID-19) has brought great public health challenges into our lives. To date, there has been no specific therapeutic protocol for this disease, which requires a study with high-quality evidence. Objectives: To analyze clinical trials on COVID-19 in Brazil. Methods: Documentary research was conducted on the clinical trial registration platform. For the search strategy, the “COVID-19” keyword was established in the “condition or disease” section and “Brazil” in the “country” section. No limit on the search period was considered. Data were analyzed and presented using descriptive statistics. Results: Of the 81 registered clinical trials, 48 met the eligibility criteria. The sample size ranged from 10 to 3,000 individuals. Most studies recruited individuals aged 18 - 64 years (48.5%) and > 65 years (48.5%). Regarding the study design, randomized (91.6%), parallel (89.5%), quadruple-blind (39.6%), and therapeutic (97.9%) types were more frequent. Most studies used standard two-arm trial (70.8%), used drugs (79.2%), placebo (58.3%), and were sponsored by pharmaceutical/biotechnology companies and universities with 33.3% and 29.2%, respectively. Conclusions: Clinical trials under development in Brazil on COVID-19 are mostly carried out with adult and elderly participants, and regarding the study design, have a predominance of randomized allocation, parallel model, quadruple-blind masking with a therapeutic purpose. Most studies use antithrombotic agents or combinations of antithrombotic agents.

This study aimed to identify the prevalence of molar-incisor hypomineralization (MIH) in schoolchildren and its association with dental caries experience. This was a cross-sectional study with a sample of 471 children aged 8 to 10 years. Data were collected via a sociodemographic questionnaire. Intra-oral clinical examination was done to identify and diagnose MIH (EAPD Criteria) as well as dental caries (ICDAS Index). Statistical analyses were performed with Person's Chi-square, Fisher's exact, and Mann-Whitney tests, and Poisson regression models were built. Statistical significance was set at an alpha-level of 0.05. The prevalence of MIH in our participants was 9.8%, with lesions being mostly of the mild form (65.2%) and affecting the first permanent molars but not the incisors in 54.2% of the children. Dental caries was observed in 88.1% of subjects. We observed a significant association between dental caries and the following variables: presence of MIH (p < 0.01; PR = 1.13), dental visit (p < 0.02; PR=0.92), and parents or legal guardians' education level (p < 0.05; PR = 1.07). A MIH diagnosis was also significantly associated with family income (p < 0.05; PR = 4.09). Children with MIH had more caries lesions on molar surfaces (p < 0.01; PR = 4.05). The prevalence of MIH was found to be moderate, based on previous studies, and the presence of enamel defect was associated with dental caries. The teeth most affected by MIH lesions were the first permanent molars.

Introduction: Violence is a serious problem in view of its magnitude and impact on the health of the population in several countries. The aim of the study was to evaluate the occurrence of head and face injuries among homicide victims in a municipality in the Northeastern region of Brazil. Materials and Methods: A cross-sectional study carried out at the Police Station for Crimes against Persons of the Civil Police, which evaluated 168 police inquiries of homicide victims notified from January 2015 to December 2018. Variables analyzed were related to the Victim's sociodemographic profile, homicide characteristics and body region involved. Descriptive data analysis and Pearson's Chi-square test ( P < 0.05) were performed. Results: There was greater involvement of men (92.9%) aged 20–29 years (36.3%), drug users (70.7%) and with a criminal record (65.9%). There was a predominance of simple homicides (92.3%), with greater occurrence on Sundays (16.7%), in the night shift (40.1%), revenge was the main reason for the crime (32%), and firearms as the main means used (89.2%). Regarding the number of body regions affected, victims were more frequently affected in 2 regions (36.5%). Head injuries were identified in 68.3% of victims, while face injuries represented 35.3%. There was an association between the presence of head injuries and number of injuries ( P < 0.05). Discussion: The prevalence of head and face injuries resulting from homicide was high and victims are predominantly young men, drug users and those with a criminal record. The association was found between the presence of head injuries and number of injuries.
