ABSTRACT Objective: To assess changes in oral health-related behavior and oral health status in Brazilian children in early childhood perceived by their parents/caregivers during social isolation caused by COVID-19. Material and Methods: A cross-sectional study with parents/caregivers of children in southeastern Brazil aged 0-5 years who responded to an online questionnaire about sociodemographic data, dietary changes, oral hygiene, and oral health status of children during the COVID-19 pandemic. Results: Of the 119 parents/caregivers, 54.60% did not observe any changes in eating habits, and 81.50% maintained their children's oral hygiene. Associations were observed between the impact of the pandemic on the family income and changes in eating habits (p=0.02) and between lower family income and dental caries perceived by parents/caregivers (p=0.05). Z tests with Bonferroni correction showed that families with drastic income reduction were more likely to consume lower-cost foods (62.50%) than families with no impact or slight reduction on family income. Parents/caregivers did not identify dental caries (89.10%), toothache (92.40%), and dental trauma (92.40%) in their children. Conclusion: Parents/caregivers of children in southeastern Brazil aged 0-5 years observed behavioral changes in the dietary habits of families whose income was impacted by the pandemic, and their perception of dental caries was significantly associated with family income.

Abstract This review aimed to assess the association between overweight/obesity and dental caries in Brazilian children/adolescents. Searches were performed in the Web of Science, Scopus, Cochrane, PubMed, Embase and SciELO, Lilacs and Open Grey literature databases up to June 2022. The Joanna Briggs Institute checklist for analytical cross-sectional studies, the checklist for cohort studies, and the checklist for case-control studies were used. A total of 41 publications were included, and 15 meta-analyses were performed. The authors analyzed the differences in weighted mean difference (MD) and odds ratios (OR), and their corresponding confidence intervals (CI) (95%) for dental caries among eutrophic and obese and/or overweight children/adolescents. Meta-analyses showed that there was no association between overweight and/or obesity and dental caries in Brazilian children/adolescents for most anthropometric reference curves using BMI (Body Mass Index). A greater experience of dental caries was associated with well-nourished adolescents in permanent dentition, compared with obese individuals in the same dentition, as classified by the CDC 2000 curve (OR = 2.53, 95% CI;1.49–4.29; p = 0.0006; I2 = 0%) in dichotomous outcome studies, and (MD = 0.61, 95%CI: 0.08–1.15; p = 0.02; I2 = 0%) in continuous studies. The strength of the evidence of the results was classified as very low, low or moderate. It was concluded that there is no association between overweight and/or obesity and dental caries in Brazilian children/adolescents for most anthropometric reference curves using BMI. A greater experience of dental caries was associated with well-nourished adolescents in permanent dentition, compared with obese individuals in the same dentition, as classified by the CDC 2000 curve. overweightobesity childrenadolescents children Science Scopus Cochrane PubMed SciELO 2022 crosssectional cross sectional casecontrol case control used 4 included 1 metaanalyses meta analyses MD OR, OR , (OR) CI (CI 95 (95% andor Metaanalyses Meta Body Index.

Abstract The social isolation measures adopted during the critical phase of the COVID-19 pandemic led children to spend most of their time at home. Isolation may alter the pattern of traumatic dental injury occurrences, inasmuch as studies point out that most traumatic accidents occur at home. Considering this scenario and the influence of emergency management on the prognosis of the injury, the aim of this study was to evaluate the experience of traumatic dental injuries in children before and during the pandemic, and the knowledge of this topic by the children’s guardians. This cross-sectional study was conducted with guardians of children aged 0 to 6 years, residing in Juiz de Fora, MG, Brazil. The guardians answered an online questionnaire addressing personal information, traumatic dental injury experience before and during the pandemic, and knowledge of this topic. Descriptive and statistical analyses were performed using Pearson’s chi-square test at a 5% significance level. The total sample consisted of 343 volunteers. A total of 95 and 92 injuries were reported before and during the pandemic, respectively; the home was the place of greatest occurrence. Most volunteers (88.1%) agreed that traumatic dental injuries are emergency situations, and were aware that the tooth/fragment had to be taken to the dentist after a fracture or avulsion (97.4%). This study revealed that the traumatic dental injury experience was similar before and during the pandemic, and that the volunteers had satisfactory knowledge, especially in recognizing the importance of immediate attention for a more favorable prognosis of these injuries.

RESUMO OBJETIVO Analisar a associação entre o peso ao nascer e a densidade mineral óssea (DMO) na adolescência. MÉTODOS Estudo de coorte de nascimentos em São Luís, Maranhão, utilizando dados de dois momentos: ao nascimento e aos 18–19 anos. A exposição foi o peso ao nascer em gramas, analisado de forma contínua. O desfecho foi a DMO, utilizando o índice Z-escore (corpo inteiro) medido pela densitometria por dupla emissão de raios X (DEXA). Foi construído modelo teórico em gráficos acíclicos direcionados para identificar o conjunto mínimo de variáveis de ajuste – renda familiar, a mãe saber ler e escrever à época do nascimento, realização de pré-natal, tabagismo durante a gestação e paridade – para avaliar a associação entre o peso ao nascer e a densidade mineral óssea na adolescência. Utilizou-se regressão linear múltipla no software Stata 14.0. O nível de significância adotado foi de 5%. RESULTADOS Dos 2.112 adolescentes, 8,2% apresentaram baixo peso ao nascer e 2,8% apresentaram DMO considerada baixa para a idade. O Z-escore médio de corpo inteiro foi de 0,19 (± 1,00). O maior peso ao nascer foi associado de forma linear e direta aos valores de DMO na adolescência (Coef.: 0,10; IC95% 0,02–0,18), mesmo após ajuste para as variáveis renda familiar (Coef.: -0,33; IC95% -0,66–0,33) e a mãe saber ler e escrever (Coef.: 0,23; IC95% 0,03–0,43). CONCLUSÕES Apesar de a associação ter sido atenuada após ajuste das variáveis, o peso ao nascer está associado de forma positiva e linear à DMO na adolescência.

ABSTRACT OBJECTIVE To analyze the association between birth weight and bone mineral density (BMD) in adolescence. METHODS A birth cohort study in São Luís, Maranhão, using data from two moments: at birth and at 18–19 years. Exposure was the birth weight in grams, continuously analyzed. The outcome was BMD, using the Z-score index (whole body) measured by double X-ray densitometry (Dexa). A theoretical model was constructed in acyclic graphs to identify the minimum set of adjustment variables – household income, the mother knowing how to read and write at the time of birth, prenatal care, tobacco use during pregnancy, and parity — to evaluate the association between birth weight and bone mineral density in adolescence. Multiple linear regression was used in Stata 14.0 software. A 5% significance level was adopted. RESULTS From 2,112 adolescents, 8.2% had low birth weight and 2.8% had a low BMD for their age. The mean full-body Z-score was 0.19 (± 1.00). The highest birth weight was directly and linearly associated with BMD values in adolescence (Coef.: 0.10; 95%CI: 0.02–0.18), even after adjustment for the variables household income (Coef.: -0.33; 95%CI: -0.66–0.33) and the mother knowing how to read and write (Coef.: 0.23%; 95%CI: 0.03–0.43). CONCLUSION Although after adjusting the variables the association attenuated, birth weight positively and linearly relates to BMD in adolescence.

ABSTRACT Objective: To evaluate the role of poverty and its related factors on early childhood caries (ECC) experience among deprived children. Material and Methods: This population-based cross-sectional study surveyed 418 children aged one to six years enrolled in Brazilian public preschools from an area of the country known for its high social deprivation. Intraoral examination of children evaluated dental caries experience (dmft). Parents/caregivers answered a questionnaire with sociodemographic indicators. Family income was dichotomized into below or above poverty line. Data analysis used Chi-square test, Mann-Whitney test, and Multivariate Logistic Regression analysis (p<0.05). Results: Predisposing variables for an increased chance of ECC were: age group 3-4 years (OR: 4.89; 95% CI: 2.32-10.31), age group 5-6-years (OR: 5.60; 95% CI: 2.60-12.04), being part of families living below poverty line (OR: 1.88; 95% CI: 1.04-3.38) and having mothers with less than nine years of schooling (OR: 2.86; 95% CI: 2.77-7.14). Children from families living below poverty line presented higher dmft (2.9 +3.8; p=0.001) and untreated dental caries (d component) (2.7 +3.7; p=0.002). Conclusion: ECC in a poor population was influenced by indicators of social deprivation. The poorest of poor children from mothers with less years of schooling were at higher risk.

ABSTRACT Objective: To assess the occurrence of dental trauma in a group of children with Autistic Spectrum Disorder (ASD) in comparison to children without the disorder. Material and Methods: This is a cross-sectional study conducted at the Department of Children and Adolescents Health in the Department of Health of Juiz de Fora, Brazil. The study included individuals with and without ASD, between three and 16 years old, and their parents/caregivers. Children/adolescents were assessed for dental trauma by clinical examination. All exams were performed by a trained and calibrated examiner (MCT), and intra-examiner reliability was previously established (Kappa=0.93). The Socio-demographic status was reported by parents/caregivers. Data analysis included descriptive statistics and generation of frequency distributions. Fisher’s exact test was used to evaluate the association between groups of children/adolescents with and without ASD about the presence of dental trauma. The significance level was set at p < 0.05. Results: Sixty children of both sexes participated in the study, thirty with a diagnosis of ASD and thirty without. The age ranging from 3 to 13 years, with an average of 7.5 ± 3.2 years. Children with ASD had a higher frequency of dental trauma than children without ASD (p=0.02), and the most frequent type of trauma was enamel fracture (57.10%), followed by enamel/dentin fracture without pulp exposure (42.90%). Conclusion: Children with ASD, when compared to children who did not have ASD, had a higher occurrence of dental trauma.

ABSTRACT Objective: To assess the association between dental caries experience, severe dental caries experience and socioeconomic determinants on oral health-related quality of life among children and their families. Material and Methods: This is a cross-sectional study whose sample was composed of children aged 4-12 years, who sought dental care in a dentistry school clinic, and their parents/caregivers. Dental caries experience and severe dental caries experience were assessed according to the DMF-T/dmf-t indexes. Parents/caregivers answered the Parental-Caregiver Perceptions Questionnaire (P-CPQ), the Family Impact Scale (FIS) and a questionnaire on socioeconomic and demographic conditions. Data analysis included the chi-square test and Poisson regression (PR). Results: The sample was composed of 105 children and their parents/caregivers. Severe dental caries experience in children was determinant for negative perception of children's OHRQoL by parents/caregivers (PR = 1.22; CI = 1.05-1.41). Negative impact on OHRQoL perceived by family members was determined by severe dental caries experience in children (PR = 1.22; CI = 1.05-1.42) and family income <5 minimum wage (PR = 1.32; CI = 1.08-1.61). Conclusion: Severe dental caries experience was associated with a negative impact on OHRQoL perceived by children and their families. Low family income was associated with a negative impact on the OHRQoL perceived by children and their families.

Abstract Information about bacterial diversity, such as the number of each species in the root canals of primary teeth, contributes to improving our effective management of infections of endodontic origin in primary teeth. This study made a qualitative and quantitative assessment of the bacteria in the root canals of primary teeth with necrotic pulp, using the fluorescence in situ hybridization (FISH) technique. Thirty-one primary teeth with pulp necrosis from 31 children were evaluated using the FISH technique, to detect the presence and density of Aggregatibacter actinomycetemcomitans, Campylobacter rectus, Enterococcus faecalis, Fusobacterium nucleatum, Porphyromonas gingivalis, Prevotella intermedia, Prevotella nigrescens, Streptococcus, Streptococcus mutans, Streptococcus sobrinus, Tannerella forsythia and Treponema denticola. Descriptive measures explained the data related to density, and Student’s t-test assessed the differences among the densities of each bacterium, according to signs and symptoms. The bacterial density was paired and correlated. All bacteria tested were detected and identified in all the samples. The average number of bacterial individuals from each species ranged from 1.9 x 108 cells/mL (S. mutans) to 3.1 x 108 cells/mL (F. nucleatum) (p > 0.05). The sum of the mean counts of each bacterium represented almost 80% of the entire microbial community. Patients with pain had significantly more T. denticola, and those with edema showed a greater density of Streptococcus and P. nigrescens (p < 0.05). This study revealed that all 12 bacteria evaluated were found in all primary teeth with pulp necrosis. There was no predominance among the species studied; all species had a similar number of individuals.

Ensaio: Avaliação e Políticas Públicas em Educação
- Journal Metrics
Resumo O documento que apresentamos é fruto da reflexão de Editores de Periódico Científicos ligados ao FEPAE Sudeste – Fórum de Editores de Periódicos da Área de Educação Sudeste – e expressa preocupações concretas sobre as condições materiais para a realização de seu trabalho, assim como, sobre os critérios de avaliação que vêm sendo utilizados para qualificar suas revistas. Orçamentos mais enxutos, o desmonte de estruturas universitárias que sustentavam muitas revistas acadêmicas e indexadores que cada vez mais complicam os procedimentos operacionais envolvidos na produção editorial, fragilizam as revistas nacionais. Falta de visibilidade sobre os processos de avaliação, ausência de diálogo sobre resultados e questões ligadas à periodicidade do QUALIS trazem uma insegurança para os autores que têm nos periódicos o veículo de divulgação de suas práticas e teorias. Queremos, assim, adensar a discussão com a comunidade científica e a Agência Reguladora Governamental, sobre os destinos que estarão reservados aos Periódicos Científicos brasileiros.
Abstract The document we presented is the result of the reflection of Editors of Scientific Journals connected to FEPAE Southeast and expresses concrete concerns about the material conditions for the realization of its work and about the evaluation criteria that have been used to qualify its journals. Cheaper budgets, dismantling of university structures that supported many academic journals and indicators which everytime complicate even more the operational procedures involved in editorial production, undermine the national journals. Lack of visibility about the evaluation procedures, absence of dialogue about results and questions connected to the Qualis frequency bring uncertainty for the authors who have in the journals a vehicle for sharing its practices and theories. This way we want to deepen the discussion with the scientific community and the Regulatory Governmental Agency - CAPES - about the destinations reserved to Brazilian Scientific Journals.

Resumo Introdução Sangue é um material biológico com alto potencial de transmissão de infecção em ambientes odontológicos, incluindo herpes simples, hepatites e AIDS. Objetivo Investigar a eficácia do luminol em detector sangue em limas endodônticas antes e após o processo de esterilização. Material e método Luminol foi utilizado para investigar a presença ou ausência de vestígios tecido sanguíneo em 50 limas endodônticas, visíveis ou não à olho nu, após a realização do tratamento endodôntico e após o processo de limpeza/esterilização. Os resultados obtidos foram tabulados e analisados estatisticamente utilizando o teste de Friedman com nível de significância de 5% (p<0,05). Resultado A olho nú, foi observado que 31/50 limas não apresentaram vestígios de sangue, 8/50 apresentaram uma leve presença de sangue e 11/50 apresentaram uma presença considerável de sangue após o tratamento endodôntico. Após a utilização do luminol, entretanto, 16/50 limas endodônticas não apresentaram vestígios de sangue, 19/50 apresentaram uma leve presença de sangue e 15/50 apresentaram uma presença considerável de sangue. Após o processo de limpeza e esterilização não foi detectado sangue nas limas endodônticas. Conclusão A solução de luminol é efetiva na detecção de tecido sanguíneo em limas endodônticas, validando o processo de limpeza/esterilização.
Abstract Introduction Blood is a biological material with high potential of infectious transmission in dental environments, including herpes simplex, hepatitis and AIDS. Aim To investigate the efficacy of luminol in detecting blood in endodontic files before and after the sterilization process. Material and method Luminol was used to investigate the presence or absence of traces of blood tissue in 50 endodontic files, visible to naked eye or not, after performing endodontic treatment and after the cleaning/sterilization process. The results obtained were tabulated and statistically analyzed by using the Friedman’s test at a significance level of 5% (p<0.05). Result By naked eye, it was found that 31/50 files showed no trace of blood, 8/50 showed a slight presence of blood and 11/50 showed a considerable presence of blood after endodontic treatment. After the use of luminol, however, 16/50 endodontic files showed no trace of blood, 19/50 showed a slight presence of blood and 15/50 showed a considerable presence of blood. After the cleaning and sterilization process, no blood was detected in the files. Conclusion It was concluded that the luminol solution is effective in detecting blood tissue in endodontic files as well as in validating the cleaning/sterilization process.

Abstract This study was aimed to provide a longitudinal overview of the subgingival bacterial microbiome using fluorescence in situ hybridization (FISH) technique, in women in the second trimester of pregnancy (between 14 and 24 weeks), and 48 h and 8 weeks postpartum. Of 31 women evaluated during pregnancy, 24 returned for the 48-h and 18 for their 8-week exams postpartum. Probing depth (PD), bleeding on probing, clinical attachment level, and presence of calculus were recorded. Subgingival plaque samples were collected, and FISH was used to identify the numbers of eight periodontal pathogens. Friedman test was used to compare differences between follow-up examinations, followed by a multiple comparison test for a post hoc pairwise comparison. Clinically, a significantly greater number of teeth with PD = 4–5 mm were found during pregnancy than on postpartum examinations. Microbial analysis showed a statistically significant decrease in cell count over the study period for Prevotella nigrescens. P. intermedia, Campylobacter rectus, and Porphyromonas gingivalis also decrease, although not significantly, and Aggregatibacter actinomycetemcomitans increased. No significant changes were found for Fusobacterium nucleatum, Treponema denticola, or Tannerella forsythia. Our data demonstrate a change in the subgingival microbiota during pregnancy, at least for P. nigrescens.

Resumo Um levantamento atualizado das plantas com sementes e análises relevantes acerca desta biodiversidade são apresentados. Este trabalho se iniciou em 2010 com a publicação do Catálogo de Plantas e Fungos e, desde então vem sendo atualizado por mais de 430 especialistas trabalhando online. O Brasil abriga atualmente 32.086 espécies nativas de Angiospermas e 23 espécies nativas de Gimnospermas e estes novos dados mostram um aumento de 3% da riqueza em relação a 2010. A Amazônia é o Domínio Fitogeográfico com o maior número de espécies de Gimnospermas, enquanto que a Floresta Atlântica possui a maior riqueza de Angiospermas. Houve um crescimento considerável no número de espécies e nas taxas de endemismo para a maioria dos Domínios (Caatinga, Cerrado, Floresta Atlântica, Pampa e Pantanal), com exceção da Amazônia que apresentou uma diminuição de 2,5% de endemicidade. Entretanto, a maior parte das plantas com sementes que ocorrem no Brasil (57,4%) é endêmica deste território. A proporção de formas de vida varia de acordo com os diferentes Domínios: árvores são mais expressivas na Amazônia e Floresta Atlântica do que nos outros biomas, ervas são dominantes no Pampa e as lianas apresentam riqueza expressiva na Amazônia, Floresta Atlântica e Pantanal. Este trabalho não só quantifica a biodiversidade brasileira, mas também indica as lacunas de conhecimento e o desafio a ser enfrentado para a conservação desta flora.
Abstract An updated inventory of Brazilian seed plants is presented and offers important insights into the country's biodiversity. This work started in 2010, with the publication of the Plants and Fungi Catalogue, and has been updated since by more than 430 specialists working online. Brazil is home to 32,086 native Angiosperms and 23 native Gymnosperms, showing an increase of 3% in its species richness in relation to 2010. The Amazon Rainforest is the richest Brazilian biome for Gymnosperms, while the Atlantic Rainforest is the richest one for Angiosperms. There was a considerable increment in the number of species and endemism rates for biomes, except for the Amazon that showed a decrease of 2.5% of recorded endemics. However, well over half of Brazillian seed plant species (57.4%) is endemic to this territory. The proportion of life-forms varies among different biomes: trees are more expressive in the Amazon and Atlantic Rainforest biomes while herbs predominate in the Pampa, and lianas are more expressive in the Amazon, Atlantic Rainforest, and Pantanal. This compilation serves not only to quantify Brazilian biodiversity, but also to highlight areas where there information is lacking and to provide a framework for the challenge faced in conserving Brazil's unique and diverse flora.

The aim of this study was to use the fluorescence in situ hybridization (FISH) technique to test the hypothesis of qualitative and quantitative differences of 8 periodontopathogens between pregnant and non-pregnant women. This cross-sectional study included 20 pregnant women in their second trimester of pregnancy and 20 non-pregnant women. Probing depth, bleeding on probing, clinical attachment level, and presence of calculus were recorded. Subgingival plaque samples were collected and the FISH technique identified the presence and numbers of Aggregatibacter actinomycetemcomitans, Tannerella forsythia, Campylobacter rectus, Porphyromonas gingivalis, Treponema denticola, Fusobacterium nucleatum, Prevotella intermedia and Prevotella nigrescens. The Mann-Whitney U-test was applied to compare the data between the two groups. The mean age, ethnicity, marital status, education, and economic level in both groups were similar. The clinical parameters showed no significant differences between pregnant and non-pregnant women. The numbers of subgingival periodontopathogens were not found to be significantly different between groups, despite the higher mean counts of P. intermedia in pregnant women. Colonization patterns of the different bacteria most commonly associated with periodontal disease were not different in the subgingival plaque of pregnant and non-pregnant women.

OBJETIVO: O objetivo deste estudo foi caracterizar o efeito das partículas de hidroxiapatita bovina (HA) nos estágios iniciais da reparação óssea em modelo de defeito ósseo em fêmur de ratos. METDOLOGIA: Defeito ósseo não crítico de 2 mm de diâmetro foi feito em cada fêmur de 25 ratos Wistar albinos. O defeito do fêmur esquerdo foi preenchido com HA enquanto a cavidade direita foi preenchida apenas com sangue. Cinco animais foram sacrificados no 1º, 3º, 5º, 7º e 14º dia pós-cirúrgico. Os cortes histológicos do tecido ósseo foram corados com hematoxicilina e eosina para comparação da resposta inflamatória por microscopia óptica. Análise histomorfométrica do tecido ósseo neoformado foi avaliado nos três últimos períodos utilizando o teste t de Student para comparação de ambos os grupos em cada período de avaliação (a=0,05). RESULTADOS: A análise histológica mostrou o mesmo padrão de reparação óssea no 1º e 3º dia; entretanto, no 5º dia pós-cirúrgico houve um maior depósito de fibras de colágeno ao redor dos cristais de hidroxiapatita e uma maior espessura do perióstio oposto. Não houve diferença histomorfométrica significativa entre os grupos em todos os períodos avaliados. CONCLUSÃO: Pode ser concluído que a hidroxiapatita não acelera os estágios inicias da reparação óssea, apesar de induzir a um maior depósito de fibras de colágeno.
PURPOSE: This study aimed to characterize the effect of bovine hydroxyapatite particles (HA) on the early stages of bone repairing in a rat femur defect model. METHODS: A non-critical 2 mm diameter bone defect was made in both femurs of 25 male albino Wistar rats. The left femurs defects were filled with HA and the right femurs defects were just let to fill with blood. Five animals were sacrificed at the 1st, 3rd, 5th, 7th or 14th post-surgery day and bone tissue sections were stained with hematoxylin and eosin for comparison of inflammatory response by light microscopy. Histomorphometrical analysis of the newly formed bone was evaluated at the three last periods, using independent t-student test to compare both groups at each period (a=0.05). RESULTS: Histological analyses showed same standard of bone repair on first and third day; however, from the fifth post-surgery day there was a higher deposit of collagen fibers surrounding the hydroxyapatite particles and a greater thickness of the opposite side periosteum. There was no significant histomorphometrical difference between groups at all periods. CONCLUSION: It can be concluded that hydroxyapatite does not accelerate the early-stage of bone repairing, despite of induction of a higher deposit of collagen fibers.
