Correlating Streptococcus mutans with dental caries in young children using a clinically applicable microbiological...

Area of Science:

• Microbiology
• Pediatric Dentistry
• Oral Health

Background:

• Dental caries is a prevalent oral disease in young children.
• Streptococcus mutans is a key bacterium implicated in caries development.
• Assessing S. mutans levels can inform caries risk assessment.

Purpose of the Study:

• To correlate Streptococcus mutans counts with dental caries prevalence in children aged 16-60 months.
• To evaluate a clinically applicable microbiological method for S. mutans quantification.
• To establish a statistically significant relationship between S. mutans and caries in the pediatric population.

Main Methods:

• Saliva samples were collected from 37 children (16-60 months old) using sterile tongue depressors.
• Samples were inoculated onto selective agar plates and incubated anaerobically at 37°C for 48 hours.
• Chi-squared and multiple regression analyses were employed to assess correlations.

Main Results:

• A highly significant relationship (p < 0.01) was observed between dental caries prevalence and S. mutans colony counts.
• The microbiological method proved effective for quantifying S. mutans in the study population.
• Higher bacterial counts were strongly associated with increased caries incidence.

Conclusions:

• Elevated Streptococcus mutans levels are a significant predictor of dental caries in young children.
• The study validates a practical microbiological approach for caries risk assessment in pediatric dentistry.
• Early identification of high S. mutans counts can guide preventive strategies against childhood caries.
