Serotype c and e streptococcus mutans from dental plaque of child-mother pairs with dental caries

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.
