Rural, low-income pregnant women and their children are at high risk for poor oral health and have low utilization rates of dental care. The Baby Smiles study was designed to increase low-income pregnant women's utilization of dental care, increase young children's dental care utilization, and improve home oral health care practices.
METHODS/DESIGN: Baby Smiles was a five-year, four-site randomized intervention trial with a 2 × 2 factorial design. Four hundred participants were randomly assigned to one of four treatment arms in which they received either brief Motivational Interviewing (MI) or health education (HE) delivered during pregnancy and after the baby was born. In the prenatal study phase, the interventions were designed to encourage dental utilization during pregnancy. After childbirth, the focus was to utilize dental care for the infant by age one. The two primary outcome measures were dental utilization during pregnancy or up to two months postpartum for the mother, and preventive dental utilization by 18 months of age for the child. Medicaid claims data will be used to assess the primary outcomes. Questionnaires were administered at enrollment and 3, 9 and 18 months postpartum (study end) to assess mediating and moderating factors.
This trial can help define the most effective way to provide one-on-one counseling to pregnant women and new mothers regarding visits to the dentist during pregnancy and after the child is born. It supports previous work demonstrating the potential of reducing mother-to-child transmission of Streptococcus mutans and the initiation of dental caries prevention in early childhood.

农村地区、低收入的孕妇及其子女的口腔健康状况较差，且看牙的概率较低。“Baby Smiles”研究旨在提高低收入孕妇对牙科护理的利用率，增加幼儿的牙科护理利用率，并改善家庭口腔保健措施。
方法/设计：“Baby Smiles”是一项为期五年、四地点的随机干预试验，采用 2×2 析因设计。400 名参与者被随机分配到四个治疗组中的一个，他们在怀孕期间和婴儿出生后接受了简短的动机访谈（MI）或健康教育（HE）。在产前研究阶段，干预措施旨在鼓励孕妇在怀孕期间看牙。分娩后，重点是让婴儿在一岁前利用牙科护理。两个主要的结局衡量标准是母亲在怀孕期间或产后两个月内看牙的情况，以及孩子在 18 个月时进行预防性牙科护理的情况。医疗补助索赔数据将用于评估主要结局。在入组时以及产后 3、9 和 18 个月（研究结束时）进行问卷调查，以评估中介和调节因素。
该试验可以帮助确定向孕妇和新妈妈提供一对一咨询的最有效方法，以了解在怀孕期间和孩子出生后看牙医的情况。它支持了先前的工作，证明了减少链球菌变异株母婴传播和在儿童早期开始预防龋齿的潜力。
