Abstract

This study aimed to identify serotype c and e Streptococcus mutans (S. mutans) in child-mother pairs and determine the relationship between serotype S. mutans and dental caries in child-mother pairs. 119 pairs of 3- to 5-year-old child and mother participated in this study. Dental caries status were examined. Plaque samples were collected from 66 pairs subjects with dental caries. Polymerase chain reaction (PCR) using gtf B primer, Sc/Se primer was performed to detect S. mutans from dental plaque. Statistical analyzed used Pearson correlation, linear regression, one-way ANOVA, and Pearson chi-square.PCR confirmed S. mutans from 46 plaque samples pairs. There was a significant relationship between child-mother caries score (p < 0.05). Child caries scores increased as mother caries score rose. Serotype c S. mutans distribution had more prevalent detected than serotype e. There was no significant relationship between serotype c/e S. mutans and child-mother caries score. There was also no significant relationship between serotype c and e S. mutans in child-mother. We found thevarious composition of serotype S. mutans in child's mother's dental plaque that could be identified in dental plaque of child, mother, or both. The presence of serotypec and e S. mutans had no relationship with caries in child-mother.
