Objective: Dental caries is both an infectious and transmissible disease. Maternal transfer of Mutans Streptococci occurs at an early age and is important in the initiation of dental caries in children. The aim of this study was to identify certain strains of Streptococcus mutans in mother-child pairs, of children with early childhood caries. Study design: Sixty mother-child pairs of healthy children aged 18–36 months were selected. Mothers with high levels of Streptococcus mutans in their saliva and only children with ECC were included. Dental plaque samples were collected from mother-child pairs. The plaque samples were stored, transferred to the laboratory and analyzed for Streptococcus mutans strains c, f, e and k, present in mother-child pairs using Real time Polymerase Chain Reaction (PCR) technique. Data obtained was subjected to statistical analysis for level of similarity in Streptococcus mutans strains present in mother-child pairs. Results: A similar distribution of Streptococcus mutans strains c, f and k was identified in 28 mother-child pairs. Streptococcus mutans strain e was seen in 18 pairs. Conclusion: Less than 50% of mother-child pairs showed similarity in distribution of Streptococcus mutans strains.

Childhood Caries

Dental caries is one of the most common childhood diseases, and people continue to be susceptible to it throughout their lives. Although dental caries can be arrested and potentially even reversed in its early stages, it is often not self-limiting and progresses without proper care until the tooth is destroyed. Early childhood caries (ECC) is often complicated by inappropriate feeding practices and heavy infection with mutans streptococci. Such children should be targeted with a professional preventive program that includes oral hygiene instructions for mothers or caregivers, along with fluoride and diet counseling. However, these strategies alone are not sufficient to prevent dental caries in high-risk children; prevention of ECC also requires addressing the socioeconomic factors that face many families in which ECC is endemic. The aim of this paper is to systematically review information about ECC and to describe why many children are suffering from dental caries.

Purpose: This study aims to determine the relation of salivary LL37 level and mutans streptococci levels in early childhood caries (ECC). Study design: A case-control study was performed in children ≤71 months old. Unstimulated whole saliva was collected and the level of salivary LL37 was measured using an enzyme-linked immunosorbent assay kit. The mutans streptococci oral bacteria were isolated from saliva and identified using a modified SB-20 culture medium (SB-20M). Data were analyzed using descriptive statistics, bivariate, and Spearman’s rank correlation analysis. Results: The was a variability of salivary LL37 level among the children and the level was significantly associated with age and races. The median (IQR) value of salivary LL37 in caries-free (CF) children was significantly higher 393.50 (580.55) ng/mL compared to 172.50 (234.65) ng/mL in the ECC group. The ECC children exhibited a significantly higher count of S. mutans and S. sobrinus compared to the CF children. An inverse weak correlation between salivary LL37 and dmft was also observed. Conclusions: The low salivary LL37 level and higher S. mutans and S. sobrinus count in ECC supported the protective role of salivary LL37 against dental caries. Further studies are required to explore the definite relation between salivary LL37 levels and dental caries.

The relationship between dental caries and mutans streptococci (ms) in children and their mothers is a key factor in the prevention of early childhood caries. Changes in early childhood caries over time in Mexican children have not been well documented. Objective: to compare the dental caries indices and presence of ms in 3- to 5-year-old children and their mothers in two surveys, the first one carried out in 1996 and the second one in 2007. Study design: cross-sectional study. Results: The first survey included 102 mother-child dyads and the second 103. Dental caries index dmfs was 7.17 (± 10.9) and 4.58 (± 7.1) in the first and second survey, respectively (p<0.05). Ms levels were higher in 1996 than in 2007 (p<0.001). The prevalence of Severe Early Childhood Caries (SECC) was 42.2% and 34.95% in first and second surveys, respectively,(p>0.05). Children with SECC showed higher counts of ms than children without this condition. A high caries index in mothers was associated with higher caries experience in their children. Conclusion: the compassions of the surveys indicated a decline in dental caries indices over an 11-year period. High caries experience in the mother had a negative impact on the oral condition of the child.

AbstractEarly childhood caries (ECC) recurrence occurs in approximately 40% of treated cases within one year. The association of Streptococcus mutans and Candida albicans with the onset of ECC is well known. Also, S. mutans strains harboring collagen-binding proteins (Cbps) avidly bind to collagen-rich dentin and are linked to increased caries risk. Here, we investigated the presence of Cbp+S. mutans and C. albicans in saliva and dental plaque of children with varying caries statuses, and their salivary microbiome. In this cross-sectional study, 143 children who were caries-free (n = 73), treated for ECC with no signs of recurrence after 6 months (n = 45), or treated for ECC and experiencing recurrence within 6 months following treatment (n = 25) were enrolled. Co-infection with C. albicans and S. mutans, especially Cbp+S. mutans, was strongly associated with caries recurrence. Subjects of the recurrence group infected with Cbp+S. mutans showed a greater burden of Candida spp. and of Mutans streptococci in dentin than those infected with Cbp- strains. Salivary microbiome analysis revealed that Streptococcus parasanguinis was overrepresented in the caries recurrence group. Our findings indicate that Cbp+S. mutans and C. albicans are intimately associated with caries recurrence, contributing to the establishment of recalcitrant biofilms.

Purpose. In order to investigate the suitability of Streptococcus mutans species biotyping by measuring the activity of selected enzymes from a commercial test, criteria were established for biotyping clinical strains from children with dental caries. In addition, the relationships between the selected biotypes, sensitivity to commonly used antibiotics, and early childhood caries were determined. Methods. A total of 142 S. mutans isolates from dental plaque of children with caries were divided into different biotypes. Patients were divided into two groups: noncavitated (1-2 in ICDAS) and cavitated (5-6 in ICDAS) lesions. Biotyping criteria were determined based on both the arbitrary method and the clusterization method. The susceptibility of the strains to amoxicillin, cefazolin, erythromycin, and teicoplanin was studied by diluting a solid medium. Results. Biotype I was the most common. Mean MIC values showed that the strains belonging to biotypes II and IV were the most sensitive to amoxicillin. For predetermined biotypes, observed differences were dependent on the severity of dental caries. Conclusions. The proposed method of S. mutans strains biotyping is relatively quick and simple to use, provided the application of suitable biotyping criteria, and may contribute to the effective prevention of dental caries induced by S. mutans.

Introduction: Malnutrition in children is one of the most prevalent global health challenges, and malnourished children have a higher risk of death from childhood diseases. Early childhood caries (ECC) is the most common chronic disease of childhood. Complications from ECC such as pain, loss of tooth/teeth, and infection can undermine a child’s nutrition and growth. Aim: This study aims to evaluate the severity of decay, missing, and filled tooth (dmft) by nutritional status using the z scores of the anthropometric measurements: height for age (HFA), weight for age (WFA), weight for height (WFH), and body mass index for age (BMIA) among children with ECC in Nigeria. Study Design: This is a cross-sectional study conducted in 5 local government areas (LGAs) in Lagos State, Nigeria. A multistage sampling technique was used. Results: A total of 273 cases of ECC were included in the analyses (mean age 4.19 ± 0.96 y). Overall, the mean dmft was 3.04 ± 2.28, and most (96%) were accounted for by untreated decay. The distribution of dmft within the different z score categories of BMIA (<–3 = severely wasted, –2 to –3 = wasted, –2 to +2 = normal, +2 to +3 = overweight and >+3 = obese) showed the highest dmft scores among the combined severely wasted and wasted groups, lowest among children with normal z scores, and intermediate in the overweight and obese groups. There was a significant negative correlation between BMIA z score, WFH z score, and dmft ( r = −0.181, P < 0.05 and r = −0.143, P < 0.05, respectively). However, the correlations between HFA z score, WFA z score, and dmft were positive but not significant ( r = 0.048, P = 0.44 and r = 0.022, P = 0.77, respectively). Conclusion: Our study showed an increased severity of dental caries among severely wasted or wasted children with ECC compared to those of normal or overweight. Knowledge Transfer Statement: The results from this study will raise awareness among clinicians and policy makers on the need for a primary prevention program for early childhood caries in countries with high burden of malnutrition and limited resources. Also, it will help draw the attention of clinicians to the caries status of malnourished children that can be managed to improve the nutritional outcomes.

Background:The aim of this study was to analyze the synergistic relationship betweenCandida albicansandStreptococcus mutansin children with early childhood caries (ECC) experience.Methods:Dental plaque and unstimulated saliva samples were taken from 30 subjects aged 3-5 years old, half with (n=15, dmft > 4) and half without (n=15) ECC. The abundance ofC. albicansandS. mutansand relative to total bacteria load were quantify by real-time PCR (qPCR). This method was also employed to investigate the mRNA expression of glycosyltransferase (gtfB) gene in dental plaque. Student’s t-test and Pearson’s correlation were used to perform statistical analysis.Results:Within the ECC group, the quantity of both microorganisms were higher in the saliva than in dental plaque. The ratio ofC. albicansto total bacteria was higher in saliva than in plaque samples (p < 0.05). We observed the opposite forS. mutans(p < 0.05). The different value ofC. albicansandS. mutansin saliva was positively correlated, and negatively correlated in dental plaque. Transcription level ofS. mutans gtfBshowed a positive correlation withC. albicansconcentration in dental plaque. Conclusion:C. albicanshas a positive correlation with cariogenic traits ofS. mutansin ECC-related biofilm of young children.
