Relationship between cariogenic bacteria and molar incisor hypomineralization in Brazilian schoolchildren.

ABSTRACT:

Background

Teeth with defects in their structure, such as the ones affected by molar-incisor hypomineralization (MIH), are more susceptible to carious lesions. Caries is a complex and multifactorial disease highly prevalent in childhood. The present research evaluated the relationship between the stages of MIH and cariogenic bacteria in children.

Methods

After examining 566 schoolchildren, four groups of 10 children each were formed: healthy (G1), mild MIH (G2 and G3), and severe MIH + caries (G4). Dental biofilm was assessed to quantify Streptococcus mutans (SM) and Lactobacillus spp. (LB) using real-time polymerase chain reaction (RT-PCR).

Results

LB counting in biofilm samples of healthy children (G1) and those with mild MIH characterized by white opa
