Objective:

To determine the oral health knowledge of pregnant women and to report their future plans to provide dental care for their expected child.

Design and setting:

Prospective cohort study; Ultrasound maternity services at St Thomas’ Hospital, London, 2014. Pregnant women attending for a routine ultrasound scan completed a questionnaire.

Results:

Women did not know that milk, dried fruit or fruit juices can cause caries. Most women knew about the benefit of fluoridated toothpaste, dental floss and sugar-free chewing gum, but only a minority knew about fluoride varnish. Most pregnant women planned to read or seek advice before purchasing their child’s first toothpaste. There was no difference regarding knowledge of prevention tools (diet and fluoride supplements) for dental caries (P>0.05) between first-time mothers and those who had children already. Though the latter knew more about toothpaste dose and timing of starting toothbrushing (P<0.05).

Discussion:

Oral health knowledge among pregnant women was deficient with respect to the cariogenicity of prolonged night-time milk feeding, dried fruits and fruit juice consumption. There was also limited knowledge of the benefit of fluoride varnish and timing of starting toothbrushing.

Conclusions:

Oral health knowledge amongst pregnant women is still deficient in many aspects. In this study population the need to improve maternal knowledge was shown.

准妈妈们需要了解哪些口腔健康知识？来自伦敦产科的队列研究

客观的：

确定孕妇的口腔健康知识，并报告她们未来为预期孩子提供牙科护理的计划。

设计与设置：

前瞻性队列研究；2014 年，伦敦圣托马斯医院的超声产科服务。参加常规超声扫描的孕妇完成了一份问卷调查。

结果：

女性不知道牛奶、干果或果汁会导致龋齿。大多数女性都知道含氟牙膏、牙线和无糖口香糖的好处，但只有少数女性知道含氟清漆。大多数孕妇计划在购买孩子的第一支牙膏之前阅读或寻求建议。初产妇与已生育儿童的龋齿预防工具（饮食和氟补充剂）知识差异无统计学意义（P >0.05）。后者对牙膏用量和开始刷牙时间的了解较多（P <0.05）。

讨论：

孕妇的口腔健康知识缺乏关于长时间夜间喂奶、干果和果汁食用的致龋性。对于氟化物清漆的益处和开始刷牙的时间也知之甚少。

结论：

孕妇的口腔健康知识在很多方面仍然存在不足。在该研究人群中，表明需要提高孕产妇知识。
