The oral hygiene of habitual chewing stick and toothbrush users who participated in an oral health education (OHE) programme in schools was evaluated. The study comprised all chewing stick users (n = 45) in standard 4 in 8 randomly selected experimental schools and all chewing stick users (n = 17) in standard 4 in 4 randomly selected control schools. Each chewing stick user was randomly matched with a toothbrush user of the same sex, age and school. Their ages ranged from 10 to 13 years with a mean of 11.5 years. The children in standard 4 of the 8 experimental schools received OHE. Among many topics aiming to improve oral health of children, the practice of systematic brushing was taught. The children practised weekly brushing sessions in schools under the supervision of instructed teachers. At baseline, the chewing stick users exhibited statistically significant more plaque, but their gingival condition was comparable with their matched toothbrush counter-parts. After 3 months, the chewing stick and the toothbrush users in the experimental schools, had reduced their plaque and gingival bleeding scores significantly to the same extent, whereas no substantial changes in oral hygiene occurred in the control group. The findings show that schoolchildren who participated in a school programme that emphasizes effective toothbrushing were able to improve their oral hygiene regardless of whether they were habitual chewing stick or toothbrush users.
对参与学校口腔健康教育（OHE）项目的习惯使用咀嚼棒和牙刷的人群的口腔卫生状况进行了评估。该研究涵盖了8所随机选择的实验学校中四年级的所有咀嚼棒使用者（n = 45）以及4所随机选择的对照学校中四年级的所有咀嚼棒使用者（n = 17）。每个咀嚼棒使用者都与一名同性、同龄且同校的牙刷使用者随机匹配。他们的年龄在10至13岁之间，平均年龄为11.5岁。8所实验学校四年级的儿童接受了口腔健康教育。在旨在改善儿童口腔健康的众多主题中，教授了系统刷牙的方法。孩子们在指导教师的监督下在学校每周进行刷牙练习。在基线时，咀嚼棒使用者的牙菌斑在统计学上显著更多，但他们的牙龈状况与匹配的牙刷使用者相当。3个月后，实验学校中咀嚼棒使用者和牙刷使用者的牙菌斑和牙龈出血分数均显著降低，且降低程度相同，而对照组的口腔卫生状况没有实质性变化。研究结果表明，参与强调有效刷牙的学校项目的学童，无论他们是习惯使用咀嚼棒还是牙刷，都能够改善他们的口腔卫生状况。
