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.

O pequeno leitor e o processo de mediação de leitura literária

This article discusses literary education from early childhood, understanding early childhood as the nursery period from zero to five years. This paper aims to make some observations about the teaching and learning of reading, their relationships with children’s literature, and the formation of literary taste. It also discusses the mediating role of the teacher in the process of literary education, and the school as a space in which this mediation should occur.

Ensino e aprendizagem da leitura e da escrita na educação de jovens e adultos: diálogos com a educação infantil

This article aims to present a discussion of the methodological aspects of teaching and learning to read and write in adult education, in an attempt to seek a dialogue with the Early Childhood Education by pointing convergent elements between these two instances. And, therefore, it proposes a reflection on the construction of human nature and ownership of reading and writing as a humanizing process from the perspective of historical-cultural theory advocated by Vygotsky and his collaborators. In this context it is presented a pedagogical situation in a public school for kindergarten in the state of Sao Paulo, followed by analysis from the perspective of Bakhtin in order to make some approximations in the teaching and learning of the mother tongue with adults and children.

Objetos lúdicos disponibilizados às crianças de 3 a 5 anos: o que encontramos na educação infantil?

The goal of this research is to identify and describe the recreational objects, or toys, children’s play and games offered by teachers from a public municipal school of early childhood education in Pederneiras, a city located inland São Paulo State. The research has started with a retrospective look of the childhood concept and of the recreational objects with in the classical era till the modernity, what has allowed to identify how to play was in history and what is its relation with education. In order to understand how the recreational objects have been seen at school we have made a survey of the oficial Brazilian documents related to the childhood education. The benchmark survey has allowed the organization of a half structured questionnaire and the Kobayashi studies (2009, 2011), was the mean used to identify and classify the recreational objects found at school. The data collected in the benchmark survey in the field remark and by the questionnaire have permitted to identify here recreational objects available by teachers in early childhood education of 3 to 5 years old children at the school mentioned and what they think about the theme, on the other hand the studies performed have allowed us to analyse the adaptation and validity of the recreational objects already found
