ABSTRACT Objective: To investigate whether children with premature birth (PB) and/or with low birth weight (LBW) have different tooth eruption patterns than those born at term or with normal weight. Material and Methods: Searches were performed in the PubMed, Cochrane Library, Sc1opus, Web of Science, LILACS, and BBO databases as well as the grey literature. Three independent reviewers were involved in study selection, data extraction, and bias assessment. The risk of bias was assessed using the Modified Newcastle-Ottawa Scale. Meta-analysis was conducted to compute the mean difference (MD) in mean chronological or adjusted age at the eruption of the first deciduous tooth between preterm children and those born at full term. The GRADE approach was used. Results: Among a total of 316 articles identified, 21 were eligible for inclusion and three were included in the meta-analysis. PB was associated with the delay in the first tooth deciduous eruption when chronological age was considered (MD: 1.36; 95%CI: 1.02–1.69) but not when considering adjusted age (MD: -0.30; 95%CI: -0.67–0.07). The evidence was graded as having very low quality. Conclusion: Based on a low certainty of evidence the PB is associated with the delayed eruption of the first deciduous tooth when considering chronological age but not when adjusted age is considered.

RESUMO Objetivo: O objetivo foi avaliar a validade e a reprodutibilidade do Sistema Internacional de Detecção e Avaliação de Cárie (ICDAS) na detecção de cárie oclusal entre estudantes de pós-graduação após o treinamento usando o programa de e-learning. Métodos: Foi selecionada uma amostra de 42 dentes decíduos com diferentes faixas de cárie oclusal. Todos os dentes foram montados em um suporte de cera e foram tiradas fotografias padronizadas (EOS Rebel XTI, Canon, NY, EUA) das superfícies oclusais. Um pesquisador experiente selecionou aleatoriamente um local específico na superfície oclusal de cada dente para ser examinado posteriormente. Quinze estudantes de pós-graduação sem experiência anterior com o ICDAS concluíram o programa de e-learning em português. Após o treinamento, o exame visual das superfícies oclusais foi realizado duas vezes, independentemente, com intervalo de duas semanas. Após o exame visual, os dentes foram seccionados longitudinalmente a 1mm do local oclusal previamente selecionado. Os dentes foram fixados em um suporte de cera e fotografados. A análise histológica foi realizada a partir dessas fotografias por um pesquisador experiente para avaliar a profundidade da desmineralização. Resultados: Os valores interexaminadores do Coeficiente de Correlação Intraclasse (ICC) entre todos os participantes variaram de 0,54 a 0,96 e a reprodutibilidade intra-examinador do ICC dos examinadores variou de 0,61 a 0,85, mostrando reprodutibilidade boa a excelente. Para detecção de lesões de esmalte e dentina (D1), o ICDAS obteve sensibilidade 0,835 e especificidade 0,756. Para lesões de dentina (D3), o método revelou um aumento na sensibilidade, mas a especificidade foi semelhante ao D1. Conclusão: O programa de treinamento em e-learning do ICDAS foi eficiente no treinamento de detecção de lesões de cárie em estudantes de pós-graduação.

ABSTRACT Objective: The aim was evaluate the validity and reproducibility of the International Caries Detection and Assessment System (ICDAS) in detecting occlusal caries among graduate students after training using the e-learning program. Methods: A sample of forty-two primary teeth with different ranges of occlusal caries was selected. All teeth were mounted on a wax support and standardized photographs (EOS Rebel XTI, Canon, NY, USA) of the occlusal surfaces were taken. An experienced researcher randomly selected one specific site on the occlusal surface of each tooth to be examined later. Fifteen graduate students with no previous experience in the ICDAS scores completed the ICDAS e-learning program in Portuguese. After the training, visual examination of the occlusal surfaces was taken twice, independently, with a two-week interval. After visual examination, the teeth were longitudinally sectioned 1mm away from the previously selected occlusal site. The teeth were fixed on a wax support and photographed. Histological analysis was performed from these photographs by an experienced researcher to evaluate the depth of demineralization. Results: The Intraclass Correlation Coefficient (ICC) inter-examiner values among all participants varied from 0.54 to 0.96 and intra-examiner ICC reproducibility of the examiners ranges from 0.61 to 0.85, showing good to excellent reproducibility. For detection of enamel and dentine lesions (D1), ICDAS obtained sensitivity 0.835 and specificity 0.756. For dentine lesions (D3), the method revealed an increase in sensitivity but specificity was similar to D1. Conclusion: ICDAS e-learning training program was efficient for the training of caries lesions detection among graduate students.

Abstract Objective: To evaluate the influence of oral health knowledge in adolescents’ oral hygiene pattern. Material and Methods: Cross-sectional study involving 291 participants aged between 14 and 19 years old enrolled in a public school in Curitiba, Brazil. A self-administered questionnaire containing five affirmations about periodontal diseases and their forms of prevention was arranged on a three-point Likert scale. Correct answers were given a weight=1 and incorrect ones, weight=0. The knowledge score (KS) was determined by the sum. Socioeconomic and demographic data were obtained by a questionnaire sent to those responsible. The oral hygiene pattern was evaluated through the simplified oral hygiene index (OHI-S) by a calibrated researcher (K=0.89). Mann-Whitney U test and univariate and multivariate Poisson regression with robust variance were used for data analysis (α=0.05). Results: There was an inversely proportional association between KS and OHI-S (p=0.018). The multiple model showed that adolescents with a lower KS (PR = 0.93, CI95%: 0.88-0.99), male gender (PR = 1.17, CI95%: 1.01-1.37) and whose caregivers presented a lower level of education (PR=1.30, CI95%: 1.03-1.64) showed a higher index of dental plaque. Conclusion: The level of oral health knowledge, the gender and the caregivers’ level of education influences the adolescents’ oral hygiene pattern.

RESUMO JUSTIFICATIVA E OBJETIVOS: A neuralgia do glossofaríngeo é uma neuropatia considerada rara que se manifesta na distribuição do IX par craniano com característica de dor em choque elétrico, muitas vezes associada à hiperalgesia e alodínea. A etiologia pode estar relacionada a alterações vasculares, a tumor intracraniano, ou ainda idiopática. O objetivo deste estudo foi relatar um caso de neuralgia do glossofaríngeo secundário a tumor intracraniano, diagnosticada em ambulatório odontológico, destacando suas manifestações clínicas e discutindo seu limite nosológico com outras dores orofaciais. RELATO DO CASO: Paciente do sexo feminino, 63 anos procurou atendimento em ambulatório odontológico de Dor Orofacial com queixa de dor intensa em choque elétrico e pontadas de início súbito na região de rebordo inferior direito e base de língua direita. Relatou que os eventos eram deflagrados e exacerbados na mastigação, ao abrir a boca, rir e falar. A hipótese diagnóstica de neuralgia do glossofaríngeo foi testada pela depleção momentânea à aplicação de benzocaína a 20% e pela remissão da dor com administração de carbamazepina (400mg/dia) por 20 dias. A paciente foi referida para serviço hospitalar de neurologia, onde após ressonância magnética foi diagnosticada lesão expansiva sólida extra-axial na cisterna pré-pontina à direita, sugestiva de meningioma. CONCLUSÃO: O profissional deve estar atento no diagnóstico diferencial das dores orofaciais, especialmente nas neuropatias episódicas, pois a etiologia tumoral deve ser descartada. Nesses casos, a rápida referência a centros terciários é fundamental para o bom prognóstico.

ABSTRACT BACKGROUND AND OBJECTIVES: The glossopharyngeal neuralgia is a neuropathy considered rare that manifests itself in the IX cranial nerve distribution characterized by an electric shock-like pain, often associated with hyperalgesia and allodynia. The etiology may be related to vascular changes, brain tumor, or even idiopathic. The aim of this study was to report a case of glossopharyngeal neuralgia secondary to a brain tumor diagnosed in a dental clinic, highlighting its clinical manifestations and discussing its nosological limit with other orofacial pain. CASE REPORT: Female patient, 63 years old, sought care at a dental outpatient clinic of Orofacial Pain complaining about an intense electric shock and jumping pain of sudden onset on the lower right edge region and right tongue base. She reported that the events were triggered and exacerbated when chewing, opening the mouth, laughing and talking. The diagnostic hypothesis of glossopharyngeal neuralgia was tested by momentary depletion to the application of benzocaine 20% and pain remission with the administration of carbamazepine (400mg/day) for 20 days. The patient was referred to the Neurology service of the hospital, where the magnetic resonance imaging presented an expansive, solid, extra-axial lesion in the right prepontine cistern, suggesting meningioma. CONCLUSION: The professional should be aware of the differential diagnosis of orofacial pains, especially in episodic neuropathies, to rule out the tumor etiology. In these cases, the quick referral to tertiary centers is fundamental for the good prognosis.

O objetivo deste trabalho foi avaliar o estoque de carbono orgânico total (COT) e nitrogênio total (NT), C e N nas frações lábeis e recalcitrantes da matéria orgânica do solo (MOS) e o índice de manejo de C, em solos sob sistema de integração lavoura-pecuária (ILP), após quatro (ILP4) e oito anos (ILP8) de implantação. Para comparação, foram utilizados outros sistemas de manejo: pastagem e lavoura em plantio direto (PD), além de vegetação nativa. O experimento foi realizado em delineamento inteiramente casualizado, com cinco repetições. A integração lavoura-pecuária, estabelecida num período de oito anos, é capaz de alcançar um novo estado estável equivalente ao sistema sob plantio direto com 23 anos de implantação. Houve acúmulo no estoque de C total de 101,0 (ILP8) e 104,2 Mg ha-1 (PD) e N total de 5,5 (ILP8) e 5,8 Mg ha-1 (PD), na camada 0-30 cm, bem como aumento no estoque de C e N nas frações lábeis e recalcitrantes da MOS. Para o ILP com oito anos, o índice de manejo de C de 88 foi superior ao dos demais sistemas de manejo e não diferiu da vegetação nativa na camada 0-10 cm, todavia, foi similar ao PD na análise de todo o perfil (0-30 cm).

The objective of this work was to evaluate the soil total organic carbon (TOC) and total nitrogen (TN) stocks, C and N in labile and recalcitrant fractions of the soil organic matter (SOM), and the C management index, in soils under integrated crop-livestock (ICL) system after four (ICL4) and eight years (ICL8) of settlement. For comparison purposes, other management systems were used: pasture and crop under no tillage (NT), besides native vegetation. The experiment was carried out in a completely randomized block design, with five replicates. The crop-livestock established in a period of eight years can reach a new steady state equivalent to the no-tillage with 23 years of implementation. There was accumulation in total organic carbon of 101.0 (ICL8) and 104.2 Mg ha-1 (NT), and N total stock of 5.5 (ICL8) and 5.8 Mg ha-1 (NT) in the 0-30 cm layer, as well as increase in the stock of labile and recalcitrant C and N fractions of SOM. For crop-livestock with eight years, the C management index of 88 was higher than other management systems, and not different from native vegetation (0-10 cm), however, it was similar to NT in the analysis of the entire profile (0-30 cm).

Na produção de mudas de maracujazeiro, deve-se atentar para o estado nutricional das plantas, cujas informações, quanto à adubação com micronutrientes como o boro, ainda são escassas para as regiões tropicais onde a fruticultura está se expandindo. O objetivo deste estudo foi avaliar os efeitos de doses de boro (B) e de material do cartão de cupinzeiro sobre componentes de crescimento e concentração de B, na parte aérea de plantas de maracujazeiro-amarelo (Passiflora edulis Sims f. flavicarpa Deg.), cultivadas em Latossolo Vermelho distrófico. O delineamento experimental foi o inteiramente casualizado, em esquema fatorial 5x4, com cinco doses de boro (0 mg dm-3 0,25 mg dm-3 0,50 mg dm-3 0,75 mg dm-3 e 1,00 mg dm-3 e quatro doses do material de cartão de cupinzeiro de montículo (0 g dm-3 25 g dm-3 50 g dm-3 e 75 g dm-3, com quatro repetições, totalizando 80 unidades experimentais. A unidade experimental foi constituída por vasos com capacidade máxima para 700 cmII;de amostras. O experimento foi realizado em casa-de-vegetação, em Dourados (MS). Os maiores valores de produção de massa seca da parte aérea, altura de plantas, área foliar, diâmetro de caule e leitura SPAD são alcançados pelas aplicações conjuntas de material do cartão, na maior dose, e entre as duas maiores doses de B. O material de cartão de cupinzeiro foi pouco efetivo, como fonte de B, para influenciar os componentes de crescimento do maracujazeiro. As concentrações de B, na parte aérea de plantas de maracujá, para todas as doses de material do cartão aplicado, decresceram com os aumentos das doses de B aplicado.

For producing passion fruit seedlings, it is necessary to pay attention to the plant nutritional status, whose information about fertilizing with micronutrients such as boron are still scarce for tropical regions where fruit growing is increasing. The aim of this study was to evaluate the effects of boron (B) rates and termites mound nest material on growth components and concentration of B on yellow passion fruit (Passiflora edulis Sims f. flavicarpa Deg.) shoots, in a Red Distrophic Latosol. The experimental design was completely randomized, in a 5x4 factorial scheme, with five B doses (0 mg dm-3 0.25 mg dm-3 0.50 mg dm-3 0.75 mg dm-3 and 1.00 mg dm-3 and four termites mound nest material rates (0 g dm-3 25 g dm-3 50 g dm-3 and 75 g dm-3, with four replications, totaling 80 experimental units. The experimental unit was composed of pots with up to 700 cmII;samples. The experiment was conducted in a greenhouse, in Dourados, Mato Grosso do Sul State, Brazil. The highest values for shoot dry matter yield, plant height, leaf area, stem diameter, and SPAD reading are obtained by a joint application of the maximum termites mound nest material dose and between the two highest B rates. The termites mound nest material was little effective as a B source to influence upon the growth components of passion fruit plants. The B concentrations on the yellow passion fruit shoots, for all termites mound nest material rates, decreased with the increases in the B rates applied.
