ABSTRACT


Aim

To compare the composition of the salivary microbiota in caries-affected vs. caries-free mutans streptococci (MS)-
positive children with mixed dentition.

Methods

Twenty eight healthy, 11-12-year-old schoolchildren with high MS
counts (>105 CFU/mL) were included in this study. The children were screened with the Dentocult SM Strip Mutans test (Orion
Diagnostica, Espoo, Finland) and examined using the International Caries Detection and Assessment System (ICDAS). The microbial
composition of the saliva was assessed using the Human Oral Microbe Identification Microarray (HOMIM). Microbial differences
between caries-affected (n18) and caries-free children (n10) were compared by Mann-Whitney analysis.

Results

The microbiota of the caries-affected vs. caries-free children was rather similar. Abiotrophia defectiva and Actinomyces meyeri/A.
odontolyticus were significantly higher in caries-affected than in caries-free children (p0.006, 0.046, respectively).
Shuttleworthia satelles was significantly higher in caries-free compared to caries-affected children (p0.031). A. defectiva and A.
meyeri/A. odontolyticus correlated positively with caries severity measured by ICDAS Caries Index (p 0.494, 0.454, 0.400
respectively) while S. satelles was negatively correlated with caries severity (p -0.489). CONCLUSIONS: Salivary A. defectiva
and A. meyeri/A. odontolyticus and are associated with caries occurrence in MS-positive children with mixed dentition.
