To assess the longitudinal association between adolescents' and their mothers' dental fear.
A longitudinal questionnaire survey study.
A randomized sample of 12-year-old adolescents were selected from local Hong Kong schools. Adolescents and their mothers self-completed the Modified Dental Anxiety Scale (MDAS). The sociodemographic background of the mothers and the oral health habits of the adolescents were also collected and these measurements were repeated at 15- and 18-years-old. Non-parametric tests (Mann-Whitney test/Kruskall Wallis test) were used to test associations between MDAS dental fear items and independent variables. Logistic regression (adjusted for family's sociodemographic background and adolescent's oral health habits) was performed to evaluate the longitudinal association between adolescents' and mothers' dental fear.
A total of 212 mother-child pairs were recruited at baseline (12-year-old adolescents). In the first and second follow-ups (15- and 18-years-old), 195 and 182 mother-child pairs completed the survey. Significant associations between mother's and child's scores in "feeling about having their teeth scraped and polished", "having teeth drilled", and 'having an injection in the gum' were found when adolescents were 12- years-old ( < 0.01) and 18-years-old ( < 0.05), but not at 15-years-old.
Adolescents' and mothers' dental fear is associated at 12-years-old and 18-years-old, but not at 15-years-old, which is likely specific to the Hong Kong context but may be extrapolated to other industrialized countries with caution.
评估青少年及其母亲的牙科恐惧之间的纵向关联。
一项纵向问卷调查研究。
从香港当地学校随机抽取12岁青少年样本。青少年及其母亲自行完成改良牙科焦虑量表（MDAS）。还收集了母亲的社会人口学背景和青少年的口腔健康习惯，并在15岁和18岁时重复这些测量。使用非参数检验（曼-惠特尼检验/克鲁斯卡尔-沃利斯检验）来检验MDAS牙科恐惧项目与自变量之间的关联。进行逻辑回归（根据家庭的社会人口学背景和青少年的口腔健康习惯进行调整）以评估青少年和母亲的牙科恐惧之间的纵向关联。
基线时（12岁青少年）共招募了212对母子。在第一次和第二次随访（15岁和18岁）中，195对和182对母子完成了调查。在青少年12岁（<0.01）和18岁（<0.05）时，发现母亲和孩子在“对刮牙和抛光牙齿的感受”、“钻牙”以及“牙龈注射”方面的得分之间存在显著关联，但在15岁时不存在。
青少年和母亲的牙科恐惧在12岁和18岁时相关，但在15岁时不相关，这可能是香港特有的情况，但谨慎起见可外推至其他工业化国家。
