The aim of this study was to evaluate the implementation of the modified Bass technique (MBT) and a brushing sequence using different instruction methods. Ninety-nine participants, aged 19-42, were randomly assigned to one of three groups (control group: no instruction; leaflet instruction group: verbal instruction using a leaflet; and demonstration group: verbal instruction supported by demonstration with a model, no leaflet). Participants were instructed twice with an interval of 2 weeks. To evaluate the implementation of the technique and brushing sequence, participants were filmed during toothbrushing at baseline and 2 weeks after the first and second instruction, respectively. The duration of brushing was measured. After the first instruction, 19% in the leaflet instruction group and 41% in the demonstration group fully performed the MBT, and 36% in both instruction groups fully adopted the brushing sequence. After the second instruction, 25% of patients in the leaflet instruction group and 62% in the demonstration group had adopted the technique completely. The brushing sequence was adopted by 63% in the leaflet instruction group and by 48% in the demonstration group. Only 16% in the leaflet group and 38% in the demonstration group adopted both the technique and brushing sequence after the second instruction. The results indicate the need to improve instructional strategies.
本研究旨在评估改良 Bass 技术（MBT）和刷牙顺序的实施情况，使用了不同的指导方法。99 名年龄在 19-42 岁之间的参与者被随机分配到三个组之一（对照组：无指导；传单指导组：使用传单进行口头指导；示范组：口头指导辅以模型示范，无传单）。参与者在两周的间隔内接受了两次指导。为了评估技术和刷牙顺序的实施情况，在基线以及第一次和第二次指导后的两周，分别在参与者刷牙时对他们进行了录像。测量了刷牙的持续时间。在第一次指导后，传单指导组有 19%的患者和示范组有 41%的患者完全执行了 MBT，两个指导组都有 36%的患者完全采用了刷牙顺序。在第二次指导后，传单指导组有 25%的患者和示范组有 62%的患者完全采用了该技术。传单指导组有 63%的患者和示范组有 48%的患者采用了刷牙顺序。只有第二次指导后，传单组有 16%的患者和示范组有 38%的患者同时采用了技术和刷牙顺序。结果表明需要改进指导策略。
