The objectives of this study were to examine: (i) the association between toothbrushing frequency and educational achievement; (ii) the influence of social status and career aspiration on this association; and (iii) whether educational achievement and career aspiration explain the gender difference in oral hygiene behaviours in Iranian adolescents in Mashhad. The sample population was sixth-grade adolescents in Mashhad, Iran. Participants completed a 37-item questionnaire with questions on socio-demographic variables, frequency of toothbrushing, educational achievement, and their career aspiration. The associations between toothbrushing frequency and other study-outcome variables were tested using binary logistic regression. The association between toothbrushing frequency and educational achievement was significant only after adjusting for the father's level of education and the child's career aspiration. Toothbrushing frequency was highly significantly associated with gender, and this association remained unaltered after adjusting for educational achievement and career aspiration. Career aspiration and toothbrushing frequency were significantly associated. In conclusion, educational achievement was not an independent indicator of reported toothbrushing frequency in Iranian adolescents in Mashhad. Father's educational level and child's career aspiration mediated the association between toothbrushing frequency and educational achievement. Educational achievement and career aspiration did not explain the gender difference in toothbrushing behaviours of Iranian adolescents.
（i）刷牙频率与学业成绩之间的关联；（ii）社会地位和职业抱负对这种关联的影响；以及（iii）学业成绩和职业抱负是否能解释伊朗马什哈德青少年口腔卫生行为中的性别差异。样本群体为伊朗马什哈德六年级的青少年。参与者完成了一份包含37个条目的问卷，内容涉及社会人口统计学变量、刷牙频率、学业成绩以及他们的职业抱负。使用二元逻辑回归检验刷牙频率与其他研究结果变量之间的关联。仅在对父亲的教育水平和孩子的职业抱负进行调整后，刷牙频率与学业成绩之间的关联才具有显著性。刷牙频率与性别高度显著相关，并且在对学业成绩和职业抱负进行调整后，这种关联保持不变。职业抱负与刷牙频率显著相关。总之，学业成绩并非伊朗马什哈德青少年报告的刷牙频率的独立指标。父亲的教育水平和孩子的职业抱负介导了刷牙频率与学业成绩之间的关联。学业成绩和职业抱负并不能解释伊朗青少年刷牙行为中的性别差异。
