Clinical Trial Summary

The purpose of this study is to determine whether a bundled best practices oral health intervention utilizing motivational interviewing versus a didactic maternal and child healthy lifestyle intervention will reduce childrens' decayed, missing and/or filled primary tooth surfaces (dmfs) measured over a 2-3 year period.


Clinical Trial Description

Early Childhood Caries (ECC) is the most common chronic disease among children. American Indian (AI) children are 4 times more likely to have untreated dental decay than white children. This is a four year parallel group randomized clinical trial evaluating the impact of a bundled best practices oral health intervention on early childhood caries in American Indian children as indicated by the number of decayed, missing and/or filled primary tooth surfaces (dmfs). The intervention is delivered during pregnancy and through child age 24-36 months. The bundled best practices include motivational interviewing with mothers and fluoride varnish applied to the child's teeth. The oral health intervention also includes Tribe-specific individual, social and health needs identified in an earlier formative assessment. The oral health intervention group (n=175 mother-child dyads) will be compared to a group (n=175 mother-child dyads) receiving a standard prenatal/postnatal healthy lifestyle intervention. This comparison Healthy Lifestyle intervention is designed to improve maternal/child health knowledge and also includes Tribe-specific individual, social and health needs identified in an earlier formative assessment. Children in both groups receive some fluoride varnish. All study treatments will be delivered by Community Health Representatives from two Tribal communities in the Western U.S. Children and caregivers will be followed until up to 3 years of age. The primary outcome measure is the average number of decayed, missing and/or filled primary tooth surfaces (dmfs) at the last follow up (24 months for the late enrollment cohort; 30-36 months of age for the early enrollment cohort). Secondary outcomes include 1) the average number of decayed, missing and/or filled primary teeth (dmft) at the last follow up; survey based measures of 2) oral health knowledge; 3) oral health behavior; 4) attitudes towards oral health care; and 5) knowledge of maternal health and child development (e.g., pregnancy related nutrition; breastfeeding; prenatal health). ;
