Few studies have evaluated gender differences in young dentists’ career focusing on career breaks and return to work. We created a cohort dataset for dentists registered in 2006 using the national survey between 2006–2016 (men, 1680; women, 984), and examined the work setting of dentists by gender 10 years after registration. The proportion of dentists on career break increased each survey year, and was more pronounced in women than in men (2006 to 2016, men, 11.2% to 14.2%; women, 7.9% to 31.0%). The proportion of those who had career breaks between 2006–2016 was 44.8% in men and 62.9% in women. In the multiple logistic regression for examining the associations between those who returned to work compared to those working continuously, in women, the odds ratios (OR) were significantly higher in those working in dental clinics (owner, OR: 5.39; employee, OR: 3.10), and those working part-time (OR: 2.07); however, in men, there was no significant association with part-time work. These results suggest during early career phase, female dentists are more likely than males to take career breaks and choose part-time on returning. These gender differences should be considered for ensuring adequate workforce in dentistry in the future.

牙医早期职业中工作状态的性别差异：对日本10年国家调查队列数据的分析

很少有研究评估年轻牙医职业中的性别差异，重点是职业中断和重返工作。我们使用2006-2016年间的全国调查（男性，1680；女性，984）为2006年注册的牙医创建了队列数据集，并检查了注册10年后按性别划分的牙医工作环境。在每个调查年度中，休假的牙医比例都在增加，女性比男性更为明显（2006年至2016年，男性为11.2％至14.2％；女性为7.9％至31.0％）。2006-2016年间职业中断者中，男性为44.8％，女性为62.9％。在多元逻辑回归分析中，在女性中，重返工作场所与连续工作的人群之间的关联性在女性中，在牙科诊所工作的女性的优势比（OR）显着更高（所有者，OR：5.39；员工，或：3.10），以及兼职员工（或：2.07）；但是，在男性中，与兼职工作没有显着关联。这些结果表明，在职业早期，女性牙医比男性更有可能休假并选择兼职返回。应考虑这些性别差异，以确保将来有足够的牙科队伍。
