The aim of this study was to evaluate the effectiveness of a preclinical oral prophylaxis education program by examining the effectiveness of the teaching module on changes to the students' attitudes towards their individual hygiene behaviors with interdental brushes (IDBs).
As being part of a new didactic program on oral interproximal prophylaxis, all preclinical third-year students (n = 96) enrolled in the 2014/15 academic year received theoretical, preclinical, and clinical lessons on interproximal prophylaxis. The evaluation of educational outcomes was linked to observed changes in students' hygiene behaviors using interdental brushes. Knowledge, skills, attitudes, satisfaction, competence and performance were also explored. The evaluation interviews were recorded at each recall, i.e., 1 week, 1 month, 3 months and 1 year after baseline.
Motivation to use IDBs is clearly related to the perception of the effectiveness of the brushes and the perception of bleeding reduction. At one week, 89.6% of subjects reported using IDBs. Individual use decreased significantly from one week to one month (-26%, p = 0.006) while a non-significant upward trend occurred between one month and three months. Among students reporting usage of IDBs at 1 year (20.8%), only 2.0% used IDBs daily. Most students would recommend IDBs to other people at the beginning (69.8%). However, this share dropped to 50% at 3 months. IDB-users prescribed more than non-users.
The implementation of a module on interdental hygiene practices in the oral health program is strongly recommended. However, corrective measures should be considered regarding the organization and frequency of recall periods in order to improve the performance of the curriculum.
本研究旨在通过评估教学模块对学生使用牙间刷（IDB）个人卫生行为态度改变的效果，来评估临床前口腔预防教育计划的效果。
作为口腔邻面预防新教学计划的一部分，所有 2014/15 学年入读临床前三年级的学生（n=96）都接受了关于邻面预防的理论、临床前和临床课程。通过学生使用牙间刷的卫生行为变化来评估教育结果。还探索了知识、技能、态度、满意度、能力和表现。每次回访（基线后 1 周、1 个月、3 个月和 1 年）都记录了评估访谈。
使用 IDB 的动机与对刷子效果的认知和对出血减少的认知明显相关。第 1 周，89.6%的受试者报告使用了 IDB。从第 1 周到第 1 个月，个人使用量显著下降（-26%，p=0.006），而第 1 个月到第 3 个月之间呈非显著上升趋势。在第 1 年报告使用 IDB 的学生中（20.8%），只有 2.0%的人每天使用 IDB。大多数学生在开始时会向其他人推荐 IDB（69.8%）。然而，这一份额在第 3 个月下降到 50%。IDB 用户比非用户开出的 IDB 更多。
强烈建议在口腔健康计划中实施关于牙间卫生实践的模块。然而，应考虑组织和召回期的频率采取纠正措施，以提高课程的效果。
