To evaluate the tooth brushing skills in children aged between 6 and 12 years and its relation with age, type of grip used, duration of brushing and gender.
A total of 105 children aged between 6 and 12 years were divided into seven groups and their plaque scores, type of grip used and duration of brushing were assessed.
The most preferred grip was the distal oblique (58.1 %). Oblique, distal oblique and power grips were more efficient (plaque reduction up to 70 %). Plaque removal efficacy improved with age (57 % in 6-year-olds and 82 % in 12-year-old children). Plaque reduction was greater when the duration of brushing was longer (82 % plaque reduction when the brushing time was >2.5 min). Overall, the mean duration of tooth brushing in children aged 6-12 years was 1.71 min (103 s).
Tooth brushing skills improved with age and the duration of tooth brushing made a significant difference to the oral hygiene status of the child. The type of grip used and gender did not influence tooth brushing ability in this group of children. Tooth brushing skills were low in children younger than 10 years of age. Hence, parental supervision is considered necessary and recommended until 10 years of age.
评估6至12岁儿童的刷牙技巧及其与年龄、握持方式、刷牙时长和性别的关系。
将105名6至12岁儿童分为七组，评估他们的牙菌斑评分、握持方式和刷牙时长。
最常用的握持方式是远端斜握式（58.1%）。斜握式、远端斜握式和动力握持式更有效（牙菌斑减少高达70%）。牙菌斑清除效果随年龄增长而提高（6岁儿童为57%，12岁儿童为82%）。刷牙时间越长，牙菌斑减少越多（刷牙时间>2.5分钟时牙菌斑减少82%）。总体而言，6至12岁儿童的平均刷牙时长为1.71分钟（103秒）。
刷牙技巧随年龄增长而提高，刷牙时长对儿童口腔卫生状况有显著影响。握持方式和性别对该组儿童的刷牙能力没有影响。10岁以下儿童的刷牙技巧较低。因此，在10岁之前，家长监督被认为是必要且推荐的。
