Abstract

Aim: Tooth brushing (TB), dental flossing (DF) and inter-dental brushing (IDB) are regarded as fundamental self-care methods for periodontal health. Few evidences on its effectiveness on periodontal health are available. Hence, this study aimed to evaluate the association of TB, DF, IDB and interaction effect with periodontal health. Materials & Methods: The nationally representative 4,766 Korean adults aged 19 years and older were cross-sectionally surveyed in 2010 and 2012 respectively. Periodontal health was defined as Community Periodontal Index 1-2 for gingivitis and 3-4 for periodontitis. The information about variables were from interview and blood analyses. Multivariable logistic regression analyses and the interaction effect between TB and proximal cleaning (PC: DF and/or IDB) were applied. Results: TB thrice or more per day and DF were associated with a lower prevalence of periodontitis by both 44%, while the preventive fraction of DF on gingivitis was 30%. The preventive fraction of interaction effects between TB thrice or more and PC were 78% for periodontitis and 68% for gingivitis among 40-59 year age group. Conclusions: TB and PC are independently associated with periodontal health. Hence, periodontists should be recommended TB thrice or more per day and PC such as DF and IDB to promote periodontal health.
