All of the tested devices promoted dental changes, especially in the anterior region, and contributed to AOB reduction during the study period. However, fixed palatal crib demonstrated greater impact on the positioning of the incisors.

Background: Fluorescent agents are added to orthodontic adhesives with the aim of making them visible under ultraviolet (UV) light, which ensures the complete, safe removal of remnants after orthodontic treatment. However, it is necessary to evaluate if the mechanical strength of these materials is maintained. Therefore, this study evaluated whether the addition of fluorescent agents influences the shear bond strength and clinical performance of a UV lightsensitive adhesive system. Methods: This study consisted of two stages: (1) In vitro phase: 40 human teeth were selected, divided at random into 2 groups (n = 20), according to the adhesive system used: UV group-adhesive with fluorescent agent, and control group-conventional adhesive. A shear bond strength test was performed using a DL 2000 universal testing machine, at a speed of 0.5 mm/min. The accessories were removed and an evaluation of the Adhesive Remnant Index (ARI) was carried out. (2) Clinical phase: 8 patients were selected and had their appliances bonded using the split-mouth design (160 teeth) with the same tested adhesive systems (UV, n = 80; control, n = 80). The patients were monitored for bonding failure for a period of 24 months. Statistical analysis was performed using the Independent t test, chi-squared tests, and Mann-Whitney test, at a level of significance of 5% and confidence interval of 95%. Results: Regarding the in vitro phase, the shear bond strength test yielded similar results in the two groups (p > 0.05) and the ARI showed statistically significant differences between the groups with a score of 1 being the most frequent ARI for both groups (70%). In addition, there was no clinical difference in terms of bonding failure between the groups (p > 0.05). Conclusion: The addition of fluorescent elements does not alter the mechanical strength and performance of the orthodontic adhesive and represents a viable alternative for clinical application.

This study aimed to assess mothers’ oral health-related knowledge and practices in immediate and late puerperium, and in the child’s first year of life. This study is a prospective cohort study, in which data were collected from 358 mothers of children born between 2013 and 2014, in immediate and late puerperium, and in children’s first year of life, by interviews with sociodemographic characterization and oral health questionnaires, and were analyzed by descriptive statistics and Chi-square test (α = 5%). Participants were mainly aged 20 to 29 years (53.9%), with 7 to 11 years of education (67.6%), from low social class (72.3%), unemployed (58.9%), married or in common-law marriage (84.1%), with more than one child (60.1%). Although 51.7% of them had received information about children’s oral health, only 0.8%, 32.4% and 13.7%, respectively, knew the concept, etiology and preventive attitudes regarding dental caries. Mothers aged under 20 and over 30 years, with lower education and from low social class presented significantly lower oral health-related knowledge. At children’s first year of life, although 78.7% of the children had already been taken to the dentist, half of them had already tasted sugary foods and drinks. It is highlighted the social determination and the need of an improvement of mothers’ oral health related knowledge and practices. Educational actions, especially in prenatal programs, are important to achieve this improvement and to decrease early childhood caries rates.Keywords: Dental Caries. Child.

Trata-se de um estudo de coorte prospectiva, no qual os dados foram coletados de 358 mães de bebês nascidos entre 2013 e 2014, no puerpério imediato, tardio e um ano após o parto, por entrevistas com perguntas sobre dados sociodemográficos e sobre saúde bucal. Os dados foram analisados por estatísticas descritivas e pelo teste Qui-quadrado (α = 5%). As participantes apresentavam, majoritariamente, idades entre 20 a 29 anos (53,9%), com 7 a 11 anos de estudo (67,6%), eram de baixa classe social (72,3%), desempregadas (58,9%), casadas ou em união estável (84,1%), e tinham mais de um filho (60,1%). Apesar de 51.7% delas afirmarem ter recebido informações sobre saúde bucal infantil, apenas 0,8%, 32,4% e 13,7%, respectivamente, sabiam o conceito, etiologia e as atitudes preventivas à cárie. Mães com idades abaixo de 20 e acima de 29 anos apresentaram menor conhecimento sobre saúde bucal do que as demais. No primeiro ano de vida, apesar de 78,7% das crianças já terem ido ao dentista, metade delas já havia experimentado alimentos e bebidas açucarados. Destaca-se a determinação social e a necessidade de melhora no conhecimento e práticas das mães sobre saúde bucal. Ações educativas, especialmente em programas de atenção pré-natal, são importantes para atingir essa melhora e, consequentemente, diminuir as taxas da cárie na primeira infância.

A radiografia digital representa um grande avanço na radiologia bucomaxilofacial porque incorpora a tecnologia informática na captura, interpretação e arquivamento de imagens radiográficas. Estudos anteriores demonstraram que é possível usar os valores de cinza no diagnóstico e na proservação das lesões ósseas. No entanto, essas aplicações dependem da qualidade do sistema radiológico e do tempo de exposição. O objetivo deste estudo foi avaliar a reprodutibilidade do valor de cinza e o ruído produzido pelo sistema IDA da Dabi Atlante, um sistema de radiografia digital direto. As radiografias foram obtidas de maneira padronizada (70 kV, 7 mA e filtração de 2,2 mm) com um sensor digital direto e um penetrômetro colocados em um fantoma a uma distância de filme-foco de 30 cm. Dez imagens radiográficas consecutivas foram obtidas com tempos de exposição de 0,10-s, 0,15-s e 0,20-s. Os valores de cinza foram analisados em cinco regiões de interesse (ROIs): tecido ósseo (TO), tecido mole (TM) e três degraus do penetrômetro (Degrau 1, Degrau 2 e Degrau 3). Os valores de cinza médios diferiram significativamente entre os tempos de exposição (p <0,05) em todos as cinco ROIs. A ROI com maior variabilidade do valor de cinza (25,36%) e ruído (9,46%) foi TM. Em conclusão, a reprodutibilidade do valor de cinza e o ruído do sistema IDA variam entre áreas com radiolucência diferente. Assim, atenção especial é necessária para o diagnóstico e proservação de lesões radiolucentes devido à interferência dos valores cinza relativamente alta.Palavras-chave: Radiografia Dentária Digital.

Previous studies have demonstrated that it is possible to use gray values in bone lesion diagnosis and follow-up. However, these applications depend on radiograph system quality and exposure time. The aim of this study was to evaluate the gray-value reproducibility and noise produced by Dabi Atlante’s IDA system, a direct digital radiography system. Radiographs were obtained in a standardized manner (70 kV, 7 mA, and 2.2-mm filtration) with a direct digital sensor and a stepwedge placed in a phantom at a 30-cm focus-film distance. Ten consecutive x-ray imaging series were completed at 0.10-s, 0.15-s, and 0.20-s exposure times. Gray values were analyzed in five regions of interest (ROIs): bone tissue (BT), soft tissue (ST), and three stepwedge steps (Step 1, Step 2, and Step 3). Mean gray values differed significantly across exposure times (p < .05) in all five ROIs. The ROI with the greatest gray-value variability (25.36%) and noise (9.46%) was ST. In conclusion, gray-value reproducibility and noise of the IDA system vary across areas with differing radiolucency. Thus, special attention is necessary for the diagnosis and follow-up of radiolucent lesions due to relatively high gray-value interference.Keywords: Radiography, Dental, Digital.

A bstract The aim and objective of this study is to report the recurrence of the treatment of the anterior open bite after 5 years of treatment. A female patient aged 8 years 6 months old had a negative vertical crossing of −4.7 mm. Early treatment with a fixed palatal grid was performed for 1 year. At the end of the treatment, the vertical overpass was 1.1 mm and after 2 years of control, the vertical overpass remained positive with 1.7 mm showing the stability of the treatment. After 5 years, and due to the sucking and lingual interposition habit, there was a recurrence of the open bite. Interdisciplinary follow-up is extremely important to eliminate the factors responsible for the origin of deleterious habits, thus solving the changes resulting from these habits and providing long-term stability.

ResumoA saúde bucal é indissociável da saúde geral, e está diretamente relacionada com a qualidade de vida do indivíduo. A manutenção da saúde bucal interfere no desenvolvimento físico e psicológico da criança, além de estar relacionada com a sua participação em atividades, incluindo a frequência escolar. Este estudo teve como objetivo avaliar as percepções em relação à saúde bucal, dieta e higiene de 37 crianças matriculadas no primeiro ano do Ensino Fundamental de uma Escola Municipal na cidade de Londrina-PR, e identificar possíveis temas falhos para serem explorados, a partir de uma ferramenta diagnóstica. As crianças foram estimuladas a preencher um questionário ilustrativo com figuras dos principais recursos de higiene e de alimentos que pudessem ter relação com a boa saúde bucal. Ao final, uma atividade de Educação em Saúde Bucal (ESB) foi realizada juntamente com os alunos, de forma interativa e informativa. A análise das respostas dos alunos mostrou um bom conhecimento sobre os malefícios de alimentos industrializados e ricos em sacarose, e o reconhecimento pelas crianças dos recursos mais comumente utilizados para a realização de higiene bucal. No entanto, demonstrou dúvidas existentes quanto à relação entre alimentos naturais e manutenção da saúde bucal, tornando evidente a necessidade de educação e promoção em saúde sobre a influência da alimentação na saúde bucal. Portanto, é necessário o uso de ferramentas de diagnóstico prévio à prática educativa, para o melhor direcionamento do tema a ser abordado. Palavras-chave: Educação em Saúde.

The object of this study was to compare the clinical complications of 4 different appliances used in the early treatment of anterior open bite (AOB), and to test the null hypothesis that there is no difference in the number of complications among the appliances. Records from 99 Class I malocclusion patients with AOB treated using bonded spurs, BS, n = 25; chin cup, CC, n = 25; fixed palatal crib, FPC, n = 25; and removable palatal crib, RPC, n = 24) were examined. The total number and frequency of clinical complications that occurred over 12 months were described and compared by using chi-square and Kruskal-Wallis tests (Dunn's post-test) (α = 5%, CI = 95%). The incidence of clinical complications was 66.7%, comprising: breakage, bond failure, maladjustment, allergy, soft-tissue lesion, loss of removable appliance and abandonment. Eighteen patients gave up treatment; this occurred more frequently in the groups with removable appliances. Regarding the total number of complications per patient, Group BS exhibited a significantly higher number than the other groups (p < 0.0001). A low frequency of complications (1 to 3) was found in the groups, except for Group BS, in which 8% of the patients presented moderate frequency (4 to 6). In terms of appliance types (fixed or removable), there was no difference in the incidence of complications (p > 0.094). The null hypothesis was rejected, since the BS group exhibited the highest total number and frequency of complications. There was no difference between fixed and removable appliances in terms of incidence of clinical complications, although more patients using removable appliances abandoned their treatment.
