Oral bacterial 16S rRNA-V4 sequencing of three Japanese adults sampled in multiple time points during a day

The project contains bacterial partial 16S rRNA sequencing data of 81 supragingival plaque samples of incisor, premolar, and molar teeth. Samples were taken from three adult Japanese males for multiple time points during a day (forenoon, evening, and night for three days). Partial bacterial 16S rRNA V4 region (typically 258 or 259 base pairs) was amplified and sequenced based on the Illumina MiSeq paired-end read sequencing protocol. Ninety-six combinations of dual index tags (Illumina D-series) were utilized. The project also contains data of four sequencing replicates for a part (4/81) of DNA samples by an independent sequencer run. All relevant research protocols and procedures were approved by Ethics Committee of Tohoku University School of Medicine, Sendai, Japan. All subjects provided written informed consent.
