Outcome Measures

Primary Outcomes (1)

  • V4-16S rRNA and ITS1 rRNA sequencing

    Supragingival plaque samples were collected from the tooth surfaces using a sterile periodontal curette. DNA extraction was performed at Sugenomik Biotechnology Laboratory for library preparation and paired-end Illumina MiSeq PE250 sequencing of the V4 region of bacterial 16S rRNA and fungal ITS1 (internal transcribed spacer 1) rRNA genes.

    6 months

Caries-free children

Genetic: Collection of supragingival plaque from caries free children

Early childhood caries

Children with early childhood caries

Genetic: Collection of supragingival plaque from caries free children

Interventions

Supragingival plaque samples were collected from posterior molar teeth
