Early childhood caries (ECC), a severe form of caries due to cross-kingdom interaction of Candida albicans and Streptococcus mutans, is a serious childhood dental disease that affects majority of the children with poor background. The present study investigated the anti-infective potential of thymol against C. albicans and S. mutans dual species for the management of ECC. Thymol, a plant derivative of the monoterpene group, has been well known for its numerous biological activities. Thymol at 300 μg/ml concentration completely arrested growth and proliferation of dual species of C. albicans and S. mutans. Rapid killing efficacy of pathogens, within a span of 2 min, was observed in the time kill assay. In addition, at sub-inhibitory concentrations, thymol effectively diminished the biofilm formation and virulence of both C. albicans and S. mutans such as yeast-to-hyphal transition, hyphal-to-yeast transition, filamentation, and acidogenicity and acidurity, respectively, in single and dual species state. qPCR analysis was consistent with virulence assays. Also, through the invertebrate model system Galleria mellonella, in vivo toxicity and efficacy of the phytocompound was assessed, and it was found that no significant toxic effect was observed. Moreover, thymol was found to be proficient in diminishing the infection under single and dual state in in vivo condition. Overall, the results from the present study illustrate the anti-infective potential of thymol against the ECC-causing dual species, C. albicans and S. mutans, and the applicability of thymol in medicated dentifrice formulation.

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.

Biofilms are organized microbial communities formed from an ecological succession. Biofilm formation functions as a mechanism of virulence and favors the development of diseases, including oral diseases such as dental caries and periodontal disease, in which the microorganisms Streptococcus mutans and Candida albicans are closely related. Previous studies have shown that interactions between S. mutans and C. albicans are associated with the pathogenesis of early childhood caries (ECC). Therefore, there is a great interest in finding new prototypes for antimicrobial drugs, mainly for the development of structural analogues of chalcones, which constitute one of the largest classes of natural products belonging to the flavonoid family and are considered strategic molecules for this purpose.

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.

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 incidence. Here, we investigated the presence of Cbp+S. mutans and C. albicans in saliva and dental plaque of children with varying caries statuses, as well as the salivary microbiome of these children. In this cross-sectional study, 143 children who were caries-free, treated for ECC with no signs of recurrence after 6 months, or treated for ECC and experiencing recurrence within 6 months following treatment 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 C. albicans and of Mutans streptococci in dentin than those infected with Cbp−S. mutans. 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.
