Abstract This quasi-experimental study aimed at investigating the combined effect of biofilm accumulation and 20% sucrose rinse on the modulation of calcium (Ca2+), phosphate (Pi), and fluoride (F-) bioavailability in saliva of children with early childhood caries (ECC). In-that, fifty-six preschoolers of both genders were evaluated according to caries experience and activity: caries-free (CF, n=28) and with ECC (n=28) and then, submitted to biofilm intervention (biofilm accumulation or no biofilm accumulation). In each situation, saliva samples were collected before and five minutes after a 20% sucrose rinse to determine the concentrations of Ca2+, Pi, and F−. Calcium concentration was significantly lower in the biofilm accumulation situation compared to the situation of biofilm mechanical control, except for children CF after sucrose rinse. Biofilm accumulation increased salivary calcium concentration in children with ECC after sucrose rinse, whereas mechanical biofilm control reduced it in both groups. The phosphate concentration was influenced by mechanical control of the biofilm in CF children. The fluoride bioavailability was reduced by sucrose rinse and biofilm accumulation in CF and ECC children. In conclusion, the combined effect of biofilm accumulation and sucrose rinse modifies the bioavailability of calcium and fluoride in the saliva of children with early childhood caries.

AbstractThis quasi-experimental study sought to investigate if the mechanical control of biofilm (3-times-a-day) modifies the saliva’s ability to buffer the oral environment after 20% sucrose rinse (SR20%) in children with early childhood caries (ECC). Here, SR20% reduced the saliva’s pH in both groups and the mechanical control of biofilm had a greater effect on this parameter after SR20% in CF children. The mechanical control of biofilm evidenced a higher buffering capacity in CF children before SR20%, which was not observed after SR20%. Otherwise, the absence of mechanical control of biofilm showed that buffering capacity was comparable in the two groups before SR20%, whereas after SR20% the saliva’s buffering capacity of CF children was higher than ECC children. When biofilm was mechanically controlled, carbonic anhydrase VI activity did not change after SR20% whereas the absence of mechanical control of biofilm reduced this enzyme activity after SR20%. In conclusion, the mechanical control of biofilm did not change saliva’s ability to buffer the oral environment after SR20% in children with ECC. On the other hand, CF children appeared to regulate more effectively the saliva’s pH than ECC children while the absence of mechanical control of biofilm mediated their pH-modifying ability after SR20%.

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).

<strong>Introduction</strong>: Saliva, a chief player in the oral cavity, is determined by its secretion rate and quality to aid either in the development of caries, or its remineralization. The ability for saliva to function as a source of calcium and phosphate increases its supportive properties as it influences the precipitation or dissolution of calcium hydroxyapatite (HAP), the principal inorganic component of dental hard tissue.<p><strong>Materials&amp;Methods</strong>: 30 healthy children, aged between 3 and 6 years old were screened and recruited for the study at the Department of Pedodontics and Preventive Dentistry of the A.B Shetty Memorial Institute of Dental Sciences, a constituent of Nitte University. The subjects were clinically examined and scored based on their decayed, missing (due to caries) and filled surfaces (dfs) and were further categorized into two equal groups of 15.</p><p><strong>Result</strong>: In the subjects with Early Childhood Caries (ECC), the mean calcium concentration in samples of unstimulated saliva was 4.2383 ± 0.8594 and in samples of stimulated saliva was 4.1965 ± 0.6240. While, the mean inorganic phosphorous concentration in samples of unstimulated saliva was 3.219 ± 0.8540and in samples of stimulated saliva was 3.0634 ± 0.5470.</p><p><strong>Conclusion</strong>: From this study, we obtained a relationship between calcium, saliva and the caries status of children with the calcium concentration decreasing with increase in the caries status, as well as on stimulation of saliva.</p>

The present cross-sectional study investigated whether Firmicutes (F) and Bacteroidetes (B) levels in the mouth reflected the gut condition in obesity and early childhood caries (ECC). Eighty preschoolers (3-5 years) were equally assigned into four groups: 1. obese + ECC, 2. obese + caries-free (CF), 3. eutrophic + ECC, and 4. eutrophic + CF. Nutritional status and ECC were assessed based on the WHO criteria. Dental biofilm and fecal samples were collected for F and B quantification using RT-PCR analysis. Data were evaluated using three-way-ANOVA and Pearson’s correlation (α = 0.05). Regardless of the anatomical location effect (p = 0.22), there were higher values for F in the obese children + ECC compared with those in obese + caries-free (CF) in both mouth and gut (p &lt; 0.05). The correlation for F at these sites was negative in obese children + ECC (r = −0.48; p = 0.03) and positive in obese children + CF (r=0.50; p = 0.03). Bacteroidetes were influenced by ECC (p = 0.03) and the anatomical location (p = 0.00), and the levels tended to be higher in the mouth of the obese children + ECC (p = 0.04). The F/B ratio was higher in the gut and was affected by the anatomical location (p = 0.00). This preliminary study suggested that modulated by ECC, counts of oral Firmicutes reflected corresponding condition in the gut of obese preschoolers. In addition, we first evidenced that the Firmicutes phylum behave differently according to the nutritional status and caries experience and that supragingival biofilm and gut could share levels of similarity.

The goals of this cross-sectional study were to characterize and compare demographic, behavioral, and environmental factors potentially associated with early childhood caries (ECC) and to assess salivary levels of mutans streptococci (MS) and lactobacilli (LB) in underserved, predominantly Hispanic children. One hundred forty-six children aged 3 to 55 months with a range of caries experience were identified and examined. ECC was primarily associated with the presence of MS and lack of access to dental care. Salivary MS levels among young children with ECC were higher than would be expected in a dentally healthy population, but lower than levels reported among older children at high risk for caries.After adjustment for age, children with log10 MS ≥ 3.0 or log10 LB ≥ 1.5 were about five times as likely (OR=4.9, 95%CI=2.0,12.0) to have ECC than those with lower bacterial levels. This study demonstrated a significant association between relatively low cariogenic bacterial levels and dental caries in infants and toddlers. Antibiotic use, exposure to lead, and anemia were not significantly associated with the number of decayed and filled surfaces or decayed and filled teeth. ECC correlated significantly with child's age and lack of dental insurance of the children, as well as inversely with both family income and the educational level of the mother of the child.

Childhood Caries

Early childhood caries (ECC) is a chronic, infectious disease that affects the primary dentition of young children. It is the result of unequal contributions of risk factors and protective factors that influence the disease. The aim of this study was to assess if the X chromosome region previously linked to caries was associated with ECC. Two hundred and fifty-nine unrelated children with no chronic illnesses from 2 to 5 years of age who had no systemic fluoride consumption were evaluated using a cross-sectional design. Data on oral habits were obtained through a questionnaire, and caries experience data were collected by clinical examination. Twenty-three markers in ten genes were studied. Genotyping of the selected polymorphisms was carried out by real-time polymerase chain reaction. Regression analyses were performed comparing individuals with and without caries experience. Of 259 subjects, 123 were caries free. The markers in Xq25.1–27.2 were associated with ECC when children were using milk bottle for longer times (p = 0.01) and had more snacks over the course of a day (p = 0.05). Conversely, the markers in the X chromosome studied here were protective for ECC (p = 0.008) in children consuming milk before going to sleep. The genes located in the X chromosome possibly contribute to ECC and have an impact on ECC depending on the dietary habits.
