Diante do impacto negativo que a ansiedade exerce sobre o atendimento odontológico, buscou-se conhecer sua prevalência e seus fatores predictores frente esse tratamento em brasileiros. Foi realizado um estudo de corte transversal, utilizando-se a escala de ansiedade de Corah para avaliar 3000 pacientes. Os resultados demonstram que 2 em cada 8 brasileiros avaliados apresentaram moderada ou severa ansiedade frente ao atendimento odontológico, verificando-se que a probabilidade de um paciente da população da qual a amostra foi extraída apresentar ansiedade é mais elevada se: for mulher (p = 0,007), da faixa etária superior a 20 anos (p = 0,006), se não possuir acesso a internet e/ou jornais (p = 0,016), se tiver baixa frequência de higiene oral (p = 0,001), se a visita dental for motivada por busca de tratamento curativo, por dor ou outro problema, ao invés de um check-up (p = 0,047), e experiência de odontalgia (p<0,001). O medo e a ansiedade a fatores odontológicos existem de fato na população brasileira e as conclusões do estudo sugerem que, além da falta de recursos econômicos, o descaso com a saúde bucal, o gênero e a idade podem aumentar o grau de ansiedade.

Over the last few years, new technologies have been developed to making cavity preparations, among which the diamond burs CVDentus® (CVDentus, São José dos Campos, Brazil) are outstanding. These points are produced by chemical deposition from the vapor phase, forming a single diamond stone, with greater durability than the conventional diamond burs. Coupled to the ultrasound appliance, they have several clinical applications in Dentistry with advantages over conventional rotary instruments, such as lower pressure, noise, vibration and heat, as well as reducing the need to use local anesthesia, contributing to minimize patient’s fear and anxiety. The aim of this study was to present the complete restorative dental treatment performed with this system in a child patient with a prior history of non-cooperative behavior. The use of this new technology offered the patient greater comfort, making it possible recondition the patient’s attitude to dental treatment, in addition to favoring conservative cavity preparations to be made.

Introduction: the patients with specials necessities ne ed a singular dentistry treatment because they have limitations due to theirs deficiency. The quality of oral health is related to the clinical situation of patient. The individuals with motor and understanding problems have poor oral health. Aim: this st udy aimed to review the literature about the importance of the early dentistry treatment of pacients with specials necessities. Methodology: the review of literature was made through t he Pubmed and Bireme. Studies about dental caries and periodontal dise a se of patient s with specials necessities had shown high index of caries and periodontal disease. Therefore it is important that there are capacity p rofessionals and multidisciplinary treatment. It is necessary to supply the dificulties of treatment like an xiety of parents, systemic problems and discrimination. Conclusion: the early treatment results in good coperation during the treatment, and the aquisition of cares for all life. The best way is a program of oral health with instructions about diet, oral hygiene, control of bacterials, motivation and interaction between patients and professionals.

The objective was to assess in women with children under 5 years old what happened to your pregnancy in relation to dental care, coupled with a probable correlation between the level of their knowledge on dental health and possible reasons which lead or have led to a late seeking such treatment. The interviews were conducted in an environment of health center in the city center and the Odontoly Faculty in Araraquara. Among the interviews mothers, 57% refused the dental treatment during pregnancy. It appears on mothers that are afraid to perform a dental treatment during pregnancy. The misinformation on this issue often associated with this belief in the medical field that dental care during the first three months of pregnancy is harmful to the baby. Such information passed on to mothers leads to a hesitancy with dental treatment during this period. The educational level of mothers did not interfere in this pursuit, and 24.5% of them avoid treatment during pregnancy. The difference, however, is between those mothers of high educational level, performing oral prevention before pregnancy.

Oral health measures directed to children are characterized by the lack of policies that consider the individual and his biopsychosocial aspects. As a consequence, it can be observed that a child´s dental experience has normally been prejudged as unpleasant and threatening. Thus, this study is aimed at investigating dental treatment from the child´s viewpoint using the theory of social representations for theoretical/methodological support. This theory was selected for being able to build practical knowledge surrounding the interrelations between social actors, the phenomenon and the world around them. The investigation was performed at the Professor José Fernandes Machado State School, located in the Ponta Negra district of Natal-RN-Brazil. The participants consisted of 30 children from the public elementary school system in the 6-10 year age group, who had undergone dental treatment within the previous year or were being treated at the time of data collection. An in-depth interview and story drawing within a theme were used as collection instruments. Thematic Content Analysis (Bardin, 2002) was used to analyze the material collected in the interviews, whereas for story drawing within a theme, in addition to content analysis, the data were also analyzed by the Coutinho model (2001). The two instruments demonstrated similarity of content as well as complementarity and contained categories associated to the model for dental treatment in children, the description of the dental office environment., the perception of the image of the dentist, as well as psychological and behavioral manifestations. The results enable us to understand determinate reactions of the children in relation to dental treatment, which has been characterized by its technical-curative approach, where the motive for seeking treatment, the manner in which it is performed and the relation of the dentist with the child are all in evidence. Thus, this study intends not only to reveal the viewpoint of children faced with dental treatment, but also to contribute to a dental practice directed towards them, in this way instilling in the professionals who attend them a more concrete awareness of the needs, anxieties and feelings of these young patients

Introdução: Crianças com fissura labiopalatina apresentam diversos fatores de risco à cárie dentária e algumas necessidades diferenciadas quanto ao tratamento odontológico. Este trabalho descreverá as etapas de um tratamento odontológico definitivo previamente a cirurgia primária de queiloplastia, com o objetivo de adequação do meio bucal de um paciente com fissura labiopalatina. Material e métodos: Será apresentada revisão da literatura, com ênfase para as particularidades odontológicas e fatores de risco, incluindo a apresentação de um caso para ilustrar o tratamento odontológico pré-operatório necessário antes das cirurgias reparadoras primárias. Resultados e discussão: Paciente do gênero masculino, negro, compareceu ao HRAC-USP aos oito anos de idade, sem tratamento prévio, apresentando fissura transforame incisivo unilateral direita. O exame clínico intrabucal revelou a presença de várias lesões cariosas e necessidade de exodontias. O plano de tratamento odontológico envolveu várias sessões e foi iniciado por condicionamento odontopediátrico, seguido por restaurações com amálgama e cimento de ionômero de vidro e exodontias, iniciando por regiões com lesões menores e onde a anestesia local causa menor desconforto. A extração dos dentes anteriores, próximos à região da fissura, foi feita sob anestesia geral no centro cirúrgico antes da queiloplastia. Conclusão: O tratamento odontológico pré-cirúrgico definitivo e com remoção completa do tecido cariado é fundamental para pacientes com fissuras labiopalatinas, pois a cárie é uma doença infecciosa e, se presente, pode contaminar a cirurgia primária, podendo inclusive comprometer seus resultados.

Lithium (Li) is the first choice to treat bipolar disorder, a psychiatric illness characterized by mood oscillations between mania and depression. However, studies have demonstrated that this drug might influence mnemonic process due to its neuroprotector, antiapoptotic and neurogenic effects. The use of Li in the treatment of cognitive deficits caused by brain injury or neurodegenerative disorders have been widely studied, and this drug shows to be effective in preventing or even alleviating the memory impairment. The effects of Li on anxiety and depression are controversial and the relationship of the effects of lithium on memory, anxiety and depression remain unknown. In this context, this study aims to: evaluate the effects of acute and chronic administration of lithium carbonate in aversive memory and anxiety, simultaneously, using the plus maze discriminative avoidance task (PMDAT); test the antidepressant effect of the drug through the forced swimming test (FS) and analyze brainderived neurotrophic factor (BDNF) expression in structures related to memory and emotion. To evaluation of the acute effects, male Wistar rats were submitted to i.p. administration of lithium carbonate (50, 100 or 200 mg/kg) one hour before the training session (PMDAT) or lithium carbonate (50 or 100 mg/kg) one hour before the test session (FS). To evaluation of the chronic effects, the doses administered were 50 or 100 mg/kg or vehicle once a day for 21 days before the beginning of behavioral tasks (PMDAT and FS). Afterwards, the animals were euthanized and their brains removed and submitted to immunohistochemistry procedure to quantify BDNF. The animals that received acute treatment with 100 and 200 mg/kg of Li did not discriminated between the enclosed arms (aversive and non-aversive) in the training session of PMDAT, showing that these animal did not learned the task. This lack of discrimination was also observed in the test session, showing that the animals did not recall the aversive task. We also observed an increased exploration of the open arms of these same groups, indicating an anxiolytic effect. The same groups showed a reduction of locomotor activity, however, this effect does not seem to be related with the anxiolytic effect of the drug. Chronic treatment with Li did not promote alterations on learning or memory processes. Nevertheless, we observed a reduction of open arms exploration by animals treated with 50 mg/kg when compared to the other groups, showing an anxiogenic effect caused by this dose. This effect it is not related to locomotor alterations since there were no alterations in these parameters. Both acute and chronic treatment were ineffective in the FS. Chronic treatment with lithium was not able to modify BDNF expression in hippocampus, amygdala and pre-frontal cortex. These results suggest that acute administration of lithium promote impairments on learning in an aversive task, blocking the occurrence of memory consolidation and retrieval. The reduction of anxiety following acute treatment may have prevented the learning of the aversive task, as it has been found that optimum levels of anxiety are necessary for the occurrence of learning with emotional context. With continued, treatment the animals recover the ability to learn and recall the task. Indeed, they do not show differences in relation to control group, and the lack of alterations on BDNF expression corroborates this result. Possibly, the regimen of treatment used was not able to promote cognitive improvement. Li showed acute anxiolytic effect, however chronic administration 4 promoted the opposite effect. More studies are necessary to clarify the potential beneficial effect of Li on aversive memory

Esta investigação objetivou a eficácia antimicrobiana de agentes desinfetantes utilizados na desinfecção dos instrumentos endodônticos, durante o período transoperatório do tratamento endodôntico. A atividade antimicrobiana dos desinfetantes álcool isopropílico, acetona e ácido peracético (PAA) foi avaliada sobre microrganismos planctônicos através de teste de contato (time kill assay), utilizando inóculo de 9,9 X 109 a 1,2 X 1012 unidades formadoras de colônia (UFC) e por determinação da concentração bactericida mínima (CBM), usando inóculo de aproximadamente 106 UFC. Os agentes químicos também foram avaliados sobre Enterococcus faecalis (E. faecalis) ATCC 29212 cultivada em matriz de dentina (ex vivo) visando a formação de biofilme. O biofilme (organismos sésseis) microbiano foi removido com limas tipo Kerr (LK), até as lâminas estarem visualmente preenchidas. As LK contaminadas foram usadas como carreadores (logo após a contaminação ou secas dentro de uma câmara de fluxo laminar por 10 minutos). As LK carreadoras foram imersas em álcool isopropílico ou acetona ambos a 80%, ou em Ácido peracético 2%, por 30 ou 60 segundos. As limas foram posteriormente colocadas em tubos de ensaio contendo caldo Enterococcosel para observar o crescimento dos enterococos viáveis. Depois, os experimentos in vivo foram realizados com LK contaminadas por material necrótico pulpar da região cervical de dentes indicados para tratamento endodôntico. As LK contaminadas foram imersas, por 30 ou 60 segundos, em 80% de acetona ou 80% de álcool isopropílico ou 2% de PAA. As limas foram então inoculadas em tubos de ensaio contendo meio tioglicolato. Os organismos que cresceram, foram identificados após o tratamento com PAA. A corrosão mediada pelos agentes químicos também foi testada, após a incubação de LK de aço inoxidável e de NiTi por 60 minutos, medindo o peso das LK antes e depois da imersão e por microscopia eletrônica de varredura (MEV). Todos os agentes químicos foram capazes de eliminar ou reduzir a viabilidade das bactérias de espécies planctônicas Gram-negativas e Gram-positivas, embora a atividade dos produtos químicos sobre E. faecalis sésseis em testes de carreadores de LK demonstrou que o álcool isopropílico ou acetona foram incapazes de eliminar a contaminação bacteriana, especialmente, quando as limas foram secas previamente à exposição aos produtos químicos, por 15 ou 30 segundos. O PAA demonstrou a melhor atividade antimicrobiana e eliminou a viabilidade das células sésseis E. faecalis de ambas as limas endodônticas tipo K úmidas ou secas, após exposição por 15 segundos (100% de eliminação). Os experimentos desenvolvidos in vivo demonstraram que o PAA foi o agente mais eficaz (p<0,05), capaz de eliminar a viabilidade dos organismos em 92% das LK imersas depois de 60 segundos, quando comparado com acetona (64%) ou com álcool isopropílico (50%). O crescimento microbiano após o contato com o PAA demonstrou que somente o grupo dos Lactobacillus sp foi resistente a essa substância química. Os agentes químicos não demonstraram ser corrosivos, após a imersão por 1 hora, tanto por pesagem quanto por MEV. Foi observado que o PAA foi o agente mais eficaz para ser utilizado como desinfetante de instrumentos, durante o período transoperatório do tratamento endodôntico.
