Presence of mutans streptococci and Candida spp. in dental plaque/dentine of carious teeth and early childhood caries

This study determined the presence of mutans streptococci and Candida spp. in supragingival. dental plaque and infected dentine of caries-free children, with early childhood caries and caries. Pooled samples of dental plaque and infected dentine were collected from 56 children aged 1-5 years, which were divided into 3 groups: early childhood caries (ECC); caries and caries-free. Infected dentine was collected in ECC and caries groups to compare the frequency of these microorganisms in the collected sites. The samples were inoculated in SB20 and SA medium, for mutans streptococci and Candida spp., respectively, and incubated at 37 degrees C for 48 h. Colony growth was verified and the identification was performed by biochemical tests and CHROMagar Candida. Fisher's test or chi-square (chi(2)) were applied (p = 0.05). The more prevalent species were S. mutans and Candida albicans in ECC (85.4% and 60.4%, respectively), independently of the sample site. S. mutans only was significantly associated with carious teeth, whether in early childhood caries or not. However, the frequency of C. albicans in ECC was higher when compared to caries and caries-free groups. There is a significant association between the presence of C. albicans and early childhood caries. (c) 2006 Elsevier Ltd. All rights reserved.

Association of free amino acids with caries experience and mutans streptococci levels in whole saliva of children with early childhood caries

Objective: The aim of the present study was to identify the free amino acid content in whole saliva of children with (CE) and without early childhood caries (CF) (ECC), correlating these findings with caries experience and mutans streptococci (MS) levels in saliva.Design: Seventy-eight healthy children, both genders, 6-71 months age, were selected to participate in the study. Following examination for dmft scores calculation, unstimulated whole saliva was collected from all 78 participants, stored at -80 degrees C, and used for amino acid analysis, on a Biochem 20 plus amino acid analyzer. Stimulated whole saliva was collected from 52 children, transported, diluted and plated on MSB agar medium for detection of MS in cfu/mL.Results: Forty different free amino acids were identified in whole saliva, with great variation in their concentration. A statistically significant relation was found between caries experience and the presence of free proline and glycine. While proline (p = 0.0182) was more frequently absent in the CF group, the absence of glycine (p = 0.0397) was more often observed in the CE group. In the presence of higher levels of MS, free glycine reduced the risk of experiencing dental caries (p = 0.0419). Conversely, the presence of proline was found to increase the risk of experiencing the disease (p = 0.0492).Conclusions: The presence of free proline and absence of free glycine in children with ECC, highly contaminated with MS, increased the chances of experiencing dental caries in the present population. Further studies are needed to better understand this phenomenon. (C) 2008 Elsevier Ltd. All rights reserved.

Presence of Candida spp. in infants oral cavity and its association with early childhood caries

Candida spp., mainly C. albicans, colonizes oral cavity of infants. Transmission by mother to childbirth, pacifier use, feeding habits and caries are factors related to Candida oral colonization. Some researches related that early childhood caries favor the oral colonization of C. albicans. The present literature review described the presence of Candida spp. in oral cavity of infants and its association with early childhood caries (ECC). The literature was searched for original papers relating Candida, pacifier and baby bottle usage and ECC.The articles, were selected using Bireme and Medline databases. Manual tracing of references cited in key papers was also elicited It can be concluded that Candida spp. colonization in the infants'oral cavity especially C. albicans, can be related to the pacifier usage, feeding habits caries lesion. The early childhood caries favor the C. albicans colonization, although it's role in the carious process need further studies to be elucidate scientifically.

Regional odontodysplasia in early childhood: A clinical and histological study

Regional odontodysplasia (RO) is a rare disorder of dental development. The affected teeth are clinically hypoplastic and hypocalcified, presenting a ghost-like appearance radiographically. The aim of this work was to report a clinical case of a child with both primary and permanent dentition affected by RO. The conducted therapy was based on a conservative approach, which consisted of follow-up clinical evaluations of the anomalous teeth. However, the endodontic treatment of the primary incisors failed. Then, the chosen option for patient rehabilitation became extraction followed by removable of prosthesis confection. The extracted teeth were processed for histological analysis. In spite of the uncertain prognosis, but taking into account the psychological aspects of the patient, a conservative approach in an attempt to maintain those viable teeth in the oral cavity should be established.

Risk factors in the mother-child relationship that predispose to the development of early childhood caries

This study focused on the risk factors in mother-child relationship that predispose babies to the development of dental caries. A prospective cohort study with 80 mother-child pairs was conducted. The mothers responded at 12, 18 and 30 months after their children's birth, to questions about variables related to diet, sucking habits, and oral care. Children were clinically examined to verify caries lesions (white spot lesions or cavitation). Data were analysed using Chi squared or Fisher's exact tests. The significance level was set at 5 %. Of the total, 3.75 % showed cavitated lesions after 18 months; 6.25 and 45 % had spot white lesions, respectively, at 18 and 30 months. The cariogenic diet was high at 12 (63.75 %) and 30 (88.75 %) months. Good oral hygiene was present in a minority of children at 12 months (46.25 %), but increased at 30 months (65 %), helping to prevent cavities and white spot lesions over this period (p = 0.0005). The variables of the blocks sucking habits and diet were not associated with caries. The lack of oral care in children was a risk factor for dental caries development.

Conhecimento sobre saúde bucal por concluintes de pedagogia

Este estudo teve por objetivo investigar as opiniões e o conhecimento de concluintes do curso de Pedagogia da cidade de Araçatuba, São Paulo, Brasil, em 2009, sobre saúde bucal. Para tanto, foi utilizado um questionário semiestruturado, abordando as opiniões dos estudantes sobre educação em saúde bucal e seu conhecimento sobre aspectos relativos à cárie dentária, à odontologia preventiva e à odontologia na primeira infância. de um universo de 120 estudantes, 92 (76,6%) consentiram participar do estudo. Destes, 86,8% acadêmicos acham que o professor deve atuar como educador em saúde bucal e 92,4% consideram importante a sua integração com profissionais de saúde. Responderam corretamente sobre o conceito de placa bacteriana e cárie dentária, respectivamente, 9% e 34,8%. Sobre o surgimento da cárie e sobre a possibilidade de se ter dentes saudáveis a vida inteira, responderam corretamente 67% e 83,7%, respectivamente. Assim, os concluintes de Pedagogia têm opiniões positivas em relação à educação em saúde bucal; entretanto, o seu conhecimento sobre a temática abordada é insatisfatório, uma vez que eles serão futuros professores e formadores de opinião.

Cárie precoce: influência de variáveis sócio-comportamentais e do locus de controle da saúde em um grupo de crianças de Araraquara, São Paulo, Brasil

O objetivo deste estudo foi verificar a relação entre a cárie precoce, variáveis sócio-comportamentais e o locus de controle da saúde em um grupo de crianças de 24 a 35 meses de idade de Araraquara, São Paulo, Brasil. Foram envolvidas todas as crianças de ambos os sexos, na mencionada faixa etária, matriculadas em sete Centros Municipais de Educação e Recreação Infantil, totalizando 110 crianças. Os exames foram realizados por um examinador, previamente, calibrado para a aplicação dos critérios propostos pela OMS para determinação da condição dentária. Um questionário foi respondido pelas mães, sendo que seu conteúdo incluía informações referentes às características sócio-econômicas, comportamentos e atitudes relacionados à saúde bucal da criança, além da escala multidimensional do locus de controle da saúde. A prevalência de cárie precoce (lesões cavitadas e não cavitadas) foi de 28,2%. Observou-se associação significativa entre a escolaridade paterna (p = 0,01) e cárie precoce; não houve associação significativa entre as médias de nenhuma das subescalas do locus de controle e a cárie precoce. Os resultados sugerem que os pais não devam ser tidos apenas como provedores, mas como uma importante influência no desenvolvimento infantil como um todo.

Dental caries prevalence in children up to 36 months of age attending daycare centers in municipalities with different water fluoride content

This study determined the prevalence of cavitated caries lesions (CCL) and early childhood caries (ECC), and the contribution of some variables in children up to 36 months of age attending daycare centers in municipalities with different fluoride levels in the water supply: AFC (adequate fluoride content) and LFC (low fluoride content). After approval of the Ethics Committee, the parents were interviewed. The children were clinically examined using the same codes and criteria established by the WHO (World Health Organization) and the ADA (American Dental Association). Fisher's exact test (p<0.05) was applied for statistical analysis of data. The dmft indices calculated in the LFC and AFC municipalities were 0.57 and 0.68, respectively. Considering all children examined, 17.6% presented CCL and 33.8% ECC. The economic classification, mother's education level and duration of breastfeeding were considered statistically significant with regards to CCL prevalence. The age group, duration of the habit of drinking milk before bedtime and age at which oral hygiene started were considered statistically significant with regards to ECC prevalence.

Construção coletiva de uma trilha ecológica no cerrado: pesquisa participativa em educação ambiental

Dentre os muitos temas ambientais que podem ser problematizados pela Educação Ambiental encontra-se a proteção aos ecossistemas. Definiu-se como tema, num projeto de Educação Ambiental, o Cerrado, bioma amplamente degradado por ações antrópicas e que faz parte do ambiente natural de Botucatu, interior de São Paulo. Com o objetivo de despertar um olhar crítico-ambiental, visando a integração do ambiente natural e urbano, o projeto, realizado com alunos da 8ª série do Ensino Fundamental, teve como eixo a construção de uma Trilha Ecológica no Cerrado. Todo o processo de planejamento, realização e avaliação da trilha foi participativo: os participantes estudaram as características do Cerrado; identificaram, na área, as espécies remanescentes; discutiram as condições de conservação da área, e tomaram decisões sobre a construção da trilha como recurso educativo. Problematizaram, coletivamente, a interação comunidade-ambiente, articulando consciência ambiental e ação educativa, concluindo sobre o potencial desencadeador deste recurso para reflexões sobre temas socioambientais. O grupo teve a oportunidade de vivenciar um trabalho educativo com crianças da educação infantil, concretizando a trilha como recurso didático-pedagógico na aproximação visitantes-educandos-ambiente.

Efeito da prática de alimentação infantil e de fatores associados sobre a ocorrência da cárie dental em pré-escolares de 18 a 48 meses

Este estudo foi realizado objetivando estudar o efeito das práticas de alimentação infantil e de fatores associados sobre a ocorrência de cárie dental. Para isso, determinou-se o ceo-d e o ceo-s em 156 crianças de 18 a 48 meses e foi aplicado às mães um questionário incluindo perguntas sobre a ocupação do pai, nível educacional da mãe, higiene bucal, época de erupção do dente e sobre práticas de alimentação infantil. Os dados obtidos foram analisados através dos testes X2 e Mann-Whitney U. A média do ceo-s foi 3,4 com 40% das crianças livres de cáries, sendo que 36 e 24% tinham um ceo-d maior que 0 e 4, respectivamente. Notou-se que 72% das crianças eram alimentadas ao seio, 17% apenas com mamadeira e 10% pelos dois meios. Das crianças alimentadas apenas com mamadeira 70% apresentaram cárie. A cárie de mamadeira foi observada em 20% das crianças, sendo que 77% destas tinham sido alimentadas por mais de 12 meses. As crianças, cujos pais eram profissionais com terceiro grau de escolaridade, tiveram significativamente menos cárie do que aquelas de pais com nível técnico ou pais operários. A prevalência de cárie na faixa etária estudada foi relativamente alta. As crianças com cárie de mamadeira tenderam a manter seus hábitos de aleitamento por mais de 12 meses, sendo que o uso de mamadeira açucarada estava presente em 100% dos casos.

A questão do meio na pedologia e suas implicações pedagógicas

Ce texte est une lecture de la conférence de Vygotsky sur la question de l'influence de la culture et de l'environnement sur la pédologie et cherche les implications pédagogiques des ces idées sur l'éducation des enfants et, en particulier, les petits enfants. Initialement, met en évidence la méthode de l'auteur que enseigne à ses auditeurs et lecteurs à penser dialectiquement, un défi que doit être confrontés par les lecteurs - habitués à penser avec la logique formelle - pour essayer de comprendre les études de Vygotsky. Deux éléments apportés par Vygotsky à la conférence sont prise pour réfléchir sur son importance pour le développement de l'enfant: la question de la langue orale et de son importance pour l'influence de la culture et de l'environnement sur le développement humain dans l'enfance et la spécificité du développement culturel dans l'enfance que dit que ce que nous pouvons parvenir à la fin ou à la suite du processus de développement est présente dans la culture depuis le début et touche et guide ce développement de l'enfant. Dans les deux cas, la discussion au sein de cette conférence de Vygotsky déclenche une révolution dans la pensée et l'action des enseignants.

Percepção de professores de educação infantil sobre a inclusão da criança com deficiência

A educação infantil é importante para o desenvolvimento da criança com necessidades especiais. Nesse processo educacional, o professor e sua percepção de educação inclusiva são fatores primordiais. Este trabalho objetivou analisar a percepção de professores de educação infantil, que quanto à prática educativa atual, diferem em relação à presença de alunos com deficiências em seus ambientes de trabalho, sobre a educação da criança com deficiência na faixa etária de 3 a 6 anos. Foram sujeitos da pesquisa 12 professores de educação infantil divididos eqüitativamente em três grupos: de escolas especiais; de escolas comuns que trabalham com crianças com deficiências inseridas em suas classes e de escolas comuns que não possuem em suas classes crianças com deficiências. A coleta de dados foi realizada através de entrevistas semi-estruturadas, gravadas em fita cassete. Foi realizada análise de conteúdo e os dados mostraram que os professores vêem como a principal contribuição do processo de inclusão a socialização da criança com deficiências, restringindo-o, porém, a crianças com possibilidades de independência. Quanto à aprendizagem, acreditam que a criança com deficiência mental é a que encontra maiores dificuldades, contrariamente à com deficiência física. Ressaltam problemas com o espaço físico, recursos materiais e humanos e relativos à formação do professor. Pôde se concluir que é preciso possibilitar aos professores uma formação que abranja conhecimentos sobre as diferentes deficiências e as necessidades educacionais relativas a estas, propiciar a adequação do espaço físico e dos recursos materiais, além de assistência técnica específica.

Growth and developmental outcomes of the extremely preterm infant

Objetive: To provide information for pediatricians and neonatologists to create realistic outcome expectations and thus help plan their actions. Sources of data: Searches were made of the Cochrane Library, MEDLINE, and Lilacs databases. Summary of the findings: The assessment of growth and development over the first 2-3 years must adjust chronological age with respect of the degree of prematurity. There is special concern regarding the prognoses of small for gestational age preterm infants, and for those with bronchopulmonary dysplasia. Attention must be directed towards improving the nutrition of extremely low birth weight infants during their first years of life; these infants have high prevalence levels of failure to catch-up on growth, diseases and rehospitalizations during their first 2 years. They are frequently underweight and shorter than expected during early childhood, but delayed catch-up growth may occur between 8 and 14 years. Extremely low birth weight infants are at increased risk of neurological abnormalities and developmental delays during their first years of life. Educational, psychological, and behavioral problems are frequent during school years. Teenage and adult outcomes show that although some performance differences persist, social integration is not impaired. Conclusions: The growth and neurodevelopment of all ELBW infants must be carefully monitored after discharge, to ensure that children and their families receive adequate support and intervention to optimize prognoses.

Restoration of severely decayed primary incisors using indirect composite resin restoration technique

Caries of primary incisors is a common problem in paediatric dentistry in some countries. The restoration of primary incisors which have been severely damaged by early childhood caries or trauma is also a difficult challenge for clinicians. This case report describes an indirect technique for the restoration of primary anterior teeth using composite resin reinforced with a fibreglass post. Over a one-year period, the crowns have demonstrated good retention and aesthetic results. The restorations were provided in two short chair-side sections, with satisfactory patient cooperation. © 2005 BSPD and IAPD.

Desempenho motor de aluno com paralisia cerebral discinética frente à adaptação das propriedades físicas de recurso pedagógico

The main purpose of this study was to analyze the modified physical properties of an educational resource for facilitating the handling of a child with dyskinetic cerebral palsy. The participant of the study was a six year old child with dyskinetic cerebral palsy enrolled in a regular early childhood education classroom. The educational resource that was selected was a brick game, in which the physical properties of weight, size and texture had been modified. The analysis was made regarding the quality of upper limb movement to the variables: righting index, scalar displacement (s), average speed (As) and time (t). The results showed that combined large size and heavy weight did not have a satisfactory outcome, affecting both grasping the educational resource and fitting. There was also inconsistency in children with cerebral palsy's responses. There is variation in the results, though a standard cannot be established. Thus, this study contributed to understanding the motor responses of a child with dyskinetic cerebral palsy when participating in a fitting activity with educational resources in which the physical properties had been modified.
