Após exame clínico e levantamento da dieta alimentar das crianças, foi realizada coleta dos espécimes de saliva, biofilme nas faixas etárias determinadas, que foram transferidos para frascos contendo meio de transporte VMGA III, submetidos a diluições seriadas em VMGA I, seguido de inoculação em meios de cultura adequados e incubação em diferentes condições redox e períodos de tempo. Além disso, a identificação dos isolados foi também realizada através de amplificação do DNA por PCR, após armazenamento dos espécimes em água ultra pura, e os níveis salivares de estreptococos do grupo mutans foram avaliados por real-time PCR. Nas faixas etárias avaliadas, não se observou correlação entre prevalência de patógenos orais e tipo de hábitos de dieta e higiene oral, sendo esta relacionada ao número de dentes irrompidos, principalmente com relação à prevalência de cocos cariogênicos e suas populações. Os microrganismos mais freqüentemente detectados aos 6 meses, pertenciam ao gênero Actinomyces, Campylobacter rectus, e à espécie Fusobacterium nucleatum. De maneira geral, aos 6 meses, a colonização da cavidade bucal dos bebês, por esses microrganismos, era transitória, por vezes não sendo observados em coletas subseqüentes. Aos 12 meses, observou-se uma elevação na prevalência de Actinomyces sp., Fusobacterium nucleatum e Streptococcus sobrinus. Nesta faixa etária, a presença de Eikenella corrodens foi... / The purpose of this study was to evaluate oral microorganisms of 50 infants and their mothers, in the ages of 6, 12, 18 and 24 months, integrants of Baby-Clinic’s preventive program (Dental School of Aracatuba- UNESP). This factor was related to diet, oral hygiene habits, presence of teeth, prevalence of caries and periodontal conditions. After clinical exam, saliva and oral biofilm were collected and stored for culture and PCR process. Salivary levels of Streptococcus mutans were measured by Real time PCR. In the ages of the infants examined, after statistical analysis, it could be observed that no correlation was found between presence of oral pathogens and diet and hygiene habits, otherwise, this correlation could be seen with increase of erupted teeth. Most frequent microorganisms found in oral flora of infants at six months were Actinomyces, Campylobacter rectus and Fusobacterium nucleatum. Microorganisms observed at one period, could not be found in the other, suggesting that it was not a resident flora. At 12 months, data revealed increase in prevalence of Actinomyces sp., Fusobacterium nucleatum e S. sobrinus. In this age, the presence of Eikenella corrodens was significant. At 18 months, significant increase in the population of Actinomyces sp., Eikenella corrodens, Fusobacterium nucleatum, Streptococcus mutans e S. sobrinus was found. At 24 months, oral microflora was similar to the anterior but Streptococcus mutans and S. sobrinus, had an increase of population. Positive correlation between microorganisms found in mouth of mother and children in all periods was observed. For this reason, educative and preventive measures, which aim control of oral biofilm, must be priority, and made associated with attendance of the infants, as mothers are main transmissive ways to their children. Besides, the control of oral biofilm, as eruption... (Complete abstract click electronic access below)

O controle utilizado foi soro fisiológico associado aos microrganismos inativados. Foi utilizado 0,1mL de uma suspensão contendo Porphyromonas gingivalis ATCC 33277, Prevotella intermedia ATCC 25611, Fusobacterium nucleatum ATCC 25586, Enterococcus faecalis ATCC 29212, Peptostreptococcus micros ATCC 33270 e Porphyromonas endodontalis ATCC 35406 inativados por calor, a qual foi misturada a 1mL de soro fisiológico ou solução aquosa ou hidroalcoólica de araçá. Para a análise edemogênica (resposta imediata), foram utilizados 18 ratos machos (Rattus norvegicus). Sob anestesia geral, os animais receberam injeção intravenosa de azul de Evans a 1%. Após 30 minutos, foi injetado 0,1mL da mistura de uma das soluções ou soro (associados aos microrganismos inativados), na região subcutânea dorsal. Os animais foram sacrificados após 3 e 6 horas e as peças obtidas colocadas em formamida por 72 horas. A leitura da análise edemogênica foi realizada em espectrofotômetro com comprimento de onda de 630ηm. Para a análise microscópica (resposta tardia), tubos de polietileno contendo as soluções ou soro fisiológico acrescidos da solução de microrganismos inativados foram implantados na região dorsal de 30 ratos machos, que foram mortos após 7 e 30 dias. Não foi observada diferença significante (p>0,05) na quantidade de edema dos diferentes grupos nos tempos pós-operatórios. Os resultados obtidos pela leitura das lâminas em microscópio óptico apontaram reparo no período de 30 dias significativamente superior ao de 7 dias... / The aim of the present study was to evaluate, in vivo, the immediate and late biological reactions of hydro alcoholic and watery solutions prepared with vegetable extract of Araça (Psidium cattleianum), associated to inactivated microorganisms. For the control group, physiological serum, associated to inactivated microorganisms, was used. For performing the investigation it was used 0.1mL of a suspension containing Porphyromonas gingivalis ATCC 33277, Prevotella intermedia ATCC 25611, Fusobacterium nucleatum ATCC 25586, Enterococcus faecalis ATCC 29212, Peptostreptococcus micros ATCC 33270 and Porphyromonas endodontalis ATCC 35406, inactivated by heat, which was mixed to 1mL of physiological serum or watery solution or hydro alcoholic extract of Araça. For the edemogenic analysis (immediate reaction), 18 male mice (Rattus norvegicus) were used. The animals, under general anesthesia, received Evans blue intra shot at 1%. Thirty (30) minutes later, 0,1mL of one of the extracts or the serum - associated to the inactivated microorganisms - was injected on the animal dorsal under skin region. The animals were sacrificed after 3 and 6 hours and the materials obtained were placed into formamide for 72 hours. The edemogenic analysis reading was made by spectrophotometer with 630ηm wavelength. For the morphological analysis (late reaction), 30 mice received implant of polyethylene duct with the extracts or the serum, added by the solution of inactivated microorganisms on the dorsal region, and after 7 and 30 days they were sacrificed. No significant difference (p>0,05) in the edema amount of the different groups was observed postoperatively. Results obtained from the reading of species, in optical microscopy, showed a repair in the 30-day-period, which was significantly superior when compared to the 7-day-period (p<0,0001)...
