caries is the most common chronic disease affecting children and adolescents in the United States,
affecting individuals from rural and underserved populations. School-based sealant programs

to their oral health needs, mainly due o a lack of interest to participate. Therefore, improving adolescent
health, particularly among vulnerable populations, requires an understanding of how to best reach

Smartphone-based health interventions are increasingly implemented in settings worldwide,
among underserved or low-income adolescent populations. Yet, how to best target messages to such
remains to be determined. Geofencing is an innovative smartphone communications technology

location or geographic area (a `geofence'). Evidence from the business sector demonstrates the
of this approach to reach target audiences; however, this approach has not been widely adopted

adolescents by using geofencing t echnology to promote the use of a school-based oral health

message development and Anderson Model for Health Services Use, this project will develop, implement, and
