Background: Streptococcus mutans is the major causative bacteria of dental caries and thought to be spread through maternal transmission. This transmission indicated by the similarity of genotypes needs to be investigated widely.

Aim: To examine the relationship between dental caries in mothers and children aged 1-3 years old based on S. mutans genotype.

Methods: Thirty-five pairs of mothers and children who were visitors of the Integrated Health Service Post were clinically examined and their samples of saliva were collected. The identification of S. mutans in saliva was acquired by conducting Polymerase Chain Reaction (PCR). The positive samples were genotyped with Arbitrarily Primed-Polymerase Chain Reaction (AP-PCR) and compared visually. Statistical analysis for correlation was conducted.

Results: The relationship between the number of S. mutans colonies on the mothers’ saliva with the number of colonies of S. mutans in children's saliva was quite strong and significant (r = 0.517 p < 0.05). There was a weak positive relationship but insignificant between the number of colonies of S. mutans in mothers' saliva with children's caries index (r = 0.085 p > 0.05). Among mothers-children pairs who had S. mutans, 60% have a similar genotype.

Conclusions: Vertical transmission of S. mutans may occur from mother to child.
