Decayed, missing, filled teeth index (DMFT\/dmft), oral hygiene index (OHI), gingival index (GI), and papillary bleeding (PB) index analyses were performed for the permanent and deciduous teeth of the patients in the pediatric dental clinic. Subgingival plaque samples were taken from the gingival groove and tooth surface with a sterile swab and stored in a -80C freezer. Following the DNA isolation, the analysis of microbiota content was performed by 16S rRNA gene sequencing method.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The oral hygiene index (p=0.045), debris index (p=0.000), gingival index (p=0.001), and papillary bleeding index (p=0.002) were significantly higher in the patient group than in the control group.
