Abstract Introduction Frequent consumption of sugars and the presence of Streptococcus mutans and Streptococcus sobrinus are correlated with higher caries experience. Objective The aim of this pilot study was to elucidate the effect of different fermentable carbohydrates on biomass formation and acidogenicity of S. mutans and S. sobrinus biofilms. Material and method Single and dual-species biofilms of S. mutans ATCC 25175 and S. sobrinus ATCC 27607 were grown at the bottom of microtiter plates at equal concentrations for 24 h at 37 °C under micro-aerobic atmosphere. Carbohydrates were added at 2% concentration: maltose, sucrose, glucose and lactose. BHI Broth (0.2% glucose) was used as negative control. Acidogenicity was assessed by measuring the pH of spent culture medium after 24 h, immediately after refreshing the culture medium and for the next 1 h and 2 h. Crystal violet staining was used as an indicator of the total attached biofilm biomass after 24 h incubation. Data were analyzed by two-way ANOVA followed by Bonferroni post hoc test. Significance level was set at 5%. Result All carbohydrates resulted in higher biomass formation in single- and dual-species biofilms when compared to the control group. Sucrose, lactose and maltose showed higher acidogenicity than the control group in both single- and dual-species biofilms after 24 h. Conclusion These findings indicate that the type of biofilm (single- or dual-species) and the carbohydrate used may influence the amount of biomass formed and rate of pH reduction.

ABSTRACT Introduction Early childhood caries (ECC) is a virulent form of dental caries that can destroy the primary dentition of toddlers and preschool children. The aim was to determine the relationship of feeding methods and oral Streptococcus mutans count in 3- to 5-year-old children with ECC. Materials and methods A cross-sectional study was conducted in children aged 3 to 5 years. Participating mothers were interviewed regarding child's demographic profile, educational level and socioeconomic status of parents, past medical and dental history of the mother and child, child's feeding habits, and dietary habits and oral hygiene practices of mother and child. Clinical examination for dental caries was done using the World Health Organization criteria (1997). Salivary samples of mother–child pair were collected to determine the pH, flow rate, and S. mutans count. Statistical tests, such as Student's t-test, analysis of variance, and Pearson's correlation were applied. Results Out of 150 mother–child pair, statistically significant difference in the caries experience was found between mothers and children with high and low S. mutans count. Moderate but statistically significant negative correlation was found between mean decayed, missing, and filled teeth of mothers and mean decayed, extracted and filled teeth (deft) of children with high S. mutans count. Regarding deft, there was no statistically significant difference between children who were exclusively breast fed (7.85 ± 2.94), exclusively bottle-fed (8.67 ± 3.98), and both breast and bottle-fed (7.77 ± 2.91). Conclusion The mean caries experience of mothers and children was 2.66 ± 2.01 and 7.82 ± 2.94 respectively, with decayed component being maximum. Moderate and significant correlation (r = 0.5) was found between S. mutans of mothers and children in saliva. Significant negative correlation was found between mothers and children with high S. mutans count (r = –0.0284; p = 0.046).

Este estudo avaliou a ação do extrato etanólico das folhas de Myrciaria cauliflora (Mart.)O.Berg. sobre três culturas de Streptococcus formadoras do biofilme dental. A atividade antimicrobiana foi determinada pelo método de difusão em meio sólido. Os dados obtidos foram satisfatórios para todas as espécies ensaiadas (Streptococcus mutans ATCC 25175, Streptococcus sobrinus ATCC 27609 e Streptococcus sanguis ATCC 10557) gerando halos de inibição quando utilizado o extrato puro e diluições 1:2 e 1:4. Os resultados incentivam a realização de novas pesquisas que viabilizem a produção de compostos com finalidade terapêutica que possam ser utilizados clinicamente na odontologia.
