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.
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.
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).
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.
本基于调查的横断面研究旨在分析牙科专业人员和没有专业牙科知识的人群（非专业人员组）在个人口腔卫生工具的使用和选择方面的口腔健康行为。
共有356人参与了调查（牙科专业人员组：160人；非专业人员组：196人）。使用标准化问卷确定有关口腔卫生习惯的信息，如牙刷使用情况、刷牙习惯以及其他口腔卫生工具的使用情况。采用卡方检验和威尔科克森检验对数据进行分析，显著性水平设定为p < 0.05。
牙科专业人员组中有93%的人使用手动牙刷，非专业人员组中有89%的人使用手动牙刷（p = 0.03）。牙科专业人员组中有57%的受访者使用电动牙刷，非专业人员组中有37%的受访者使用电动牙刷（p < 0.01）。在牙科专业人员组中，刷牙时间明显更长，且比非专业人员组更频繁（p < 0.001）。非专业人员组中牙线和牙缝刷的使用率（牙线38%，牙缝刷5%）明显低于牙科专业人员组（牙线84%，牙缝刷11%；p < 0.001）。
口腔健康行为调查结果显示两组之间存在显著差异。个人口腔卫生额外工具（如牙线和牙缝刷）的接受度较低。鉴于这些工具对生物膜控制非常重要，应在家庭口腔护理的激励措施和指导中予以强调。
