Factors associated with knowledge and attitude to the use of dental floss at some private and public dental clinics in Lagos State

Aims: Dental caries and periodontal diseases which are the two most prevalent oral diseases are dental biofilm dependent. This effect of dental plaque is particularly evident in the interproximal region. The aim of this study was to determine the factors that are associated with knowledge and positive attitude towards the use of dental floss at the Lagos State University Teaching Hospital, Ikeja, (LASUTH) and two private dental clinics in Ikeja and Magodo, Lagos State. Methods: This prospective descriptive study was conducted at the oral diagnosis clinic of LASUTH and at two private dental clinics in Lagos State. A structured interviewer administered questionnaire was used to obtain information on socio-demographic items and on the participant's perception regarding gum inflammation, their oral hygiene practices and their knowledge, attitude and practices related to flossing. Results: The study population included dental patients aged 22–68 years. Majority of the respondents in this present study had poor knowledge and attitude on the use of dental floss. Respondents attending the private clinics had significantly better knowledge on the practice of oral hygiene and the use of dental floss (p = 0.000) and they also had a more positive attitude even though the association was not significant. (p = 0.364) The study participants that had a good knowledge and positive attitude on dental floss usage and oral hygiene had lower mean OHI-S, GI and DMFT scores even though the association was not significant. Conclusion: This study demonstrated a poor level of knowledge and attitude to the use of dental floss among the respondents. Oral health care professionals should spend adequate time to educate their patients on the benefits of interproximal cleaning especially floss usage. They should also enhance the self-efficacy and knowledge of their patients about the benefits of interdental hygiene.
