Purpose: The aim of this survey-based cross-sectional study was to analyse the oral health behaviour of dental professionals
and persons without professional dental knowledge (layperson group) regarding the use and selection of
tools for their personal dental hygiene.
Materials and Methods: A total of 356 persons participated in the survey (dental professional group: 160; layperson
group: 196). Information regarding dental hygiene habits, such as toothbrush use, toothbrushing habits, and
the use of additional dental hygiene tools was determined using a standardised questionnaire. Data were analysed
using the chi-squared and Wilcoxon tests, with significance set at p < 0.05.
Results: 93% of the dental professional group and 89% of layperson group used manual toothbrushes (p = 0.03).
Power toothbrushes were used by 57% of those surveyed in the dental professional group and 37% of those in the
layperson group (p < 0.01). In the dental professional group, the duration of toothbrushing was significantly longer
and it was performed more often compared to layperson group (p < 0.001). The use of dental floss and interdental
brushes in the layperson group (dental floss 38%, interdental brush 5%) was considerably lower than in the dental
professional group (dental floss 84%, interdental brush 11%; p < 0.001).
Conclusion: The results of the survey on oral health behaviour revealed significant differences between the groups.
The acceptance of additional tools for personal dental hygiene was low, such as dental floss and interdental
brushes. Given the great importance of these tools for biofilm control, they should be emphasised in motivational
measures and instructions regarding oral care performed at home.
