Twin brothers and sisters. Do they all floss?

The purpose of this study is to unravel gender effects on preventive dental procedures and gingival bleeding, periodontal microbiome and oral malodor, using the co-twin study model. After a 2-week of supervised and unsupervised treatment regimen consisting of tongue brushing and tooth brushing, or tongue brushing, tooth brushing and dental flossing, twins were examined for gingival bleeding and oral malodor. Twins who flossed had a significant decrease in gingival bleeding when compared to twins who did not floss independent of age and gender (p<0.001). Both treatment regimens demonstrated highly statistically significant reductions (p<0.0001) in oral malodor adjusted for gender but the differences between groups were not statistically significant. In addition, a comprehensive analysis of the interproximal oral microbiome clearly showed that the combination of tooth and tongue brushing plus flossing had a significant effect on suppressing periodontal pathogens compared to the group that did not floss after adjusting for gender. Contrary to what is observed in dental caries, gender does not appear to influence periodontal parameters, oral malodor, and the interproximal microbiome in light of preventive dental procedures.
