ext message interventions have the potential to improve the oral health of at-risk children by positively influencing caregivers’ attitudes and behaviors toward their children’s oral health, according to the results of a randomized pilot feasibility trial published in November 2019 in the Journal of Medical Internet Research- mHealth and uHealth.
Research, they developed a text-message program focused on motivating adherence to pediatric oral health behaviors. They based the program content and structure on clinical guidelines as well as on feedback from a multidisciplinary scientific advisory board, the medical community, and parents in the target population.
“The most effective interventions are those that are integrated into the daily fabric of people’s lives,” said Belinda Borrelli, PhD, the studies lead co-principal investigator and professor of Health Policy & Health Services Research at GSDM, where she also directs the Center for Behavioral Science Research. “Through text messaging, we can target previously unreachable populations with evidence-based information that they can access in real time – most people carry their cell phones throughout the day – wherever they happen to be when the text comes in.”
Participants in the study were parents or caregivers of children who were patients of pediatric clinics (patient treatment centers) in two community health centers in an urban and underserved area of Boston. They were randomized to receive either oral health text messages or child wellness text messages. Text messages in both groups were interactive, focusing on problem-solving barriers to behavior change.
The feasibility trial (Borrelli et al.) explored the efficacy of harnessing the power of text messaging – currently used by more than 95 percent of adults, with no disparities in race, ethnicity, and income – to improve pediatric oral health among at-risk populations. These at-risk populations have disproportionate rates of untreated dental decay and lack adequate access to dental care.

These findings from the eight-week feasibility trial indicated first that the intervention, as designed, was effective at reaching and engaging its target audience. They also demonstrated the potential of the intervention to change behavior and beliefs related to oral health. Based on the results of the feasibility trial, Borrelli and Henshaw secured a $3.5 million grant from the National Institute of Dental and Craniofacial Research to conduct a larger trial on the text message intervention; currently, 753 families are enrolled in the study. The study is assessing the text messaging program’s impact on preventing new cavities in preschool children.
