Effectiveness of preventive oral health care in Hispanic children living near US–Mexico border

Abstract

The effect of preventive oral healthcare on dental caries in Hispanic children in a school district near the US-Mexico border in Texas was studied. We collected socioeconomic and demographic data for enrolled students through a written survey of parents. The information was linked to screening data for students in the same school that had been collected during a previously completed teledentistry demonstration project. The presence of dental sealants served as a proxy for preventive oral healthcare. We compared the effect of sealant presence on caries. The student population was 97.5% Hispanic and 82% were economically disadvantaged. Forty-four percent of the children in our study sample had caries. The prevalence of sealants was 19%; 32% is the national average. The results of regression models confirm the hypothesis that preventive services significantly reduce the occurrence of dental caries (OR = 0.241, P < 0.01). Higher household income (OR = 0.437, P < 0.05) and parent health insurance (OR = 0.497, P < 0.05) were also associated with reduced caries incidence. Our study suggests that preventive services reduce the incidence of caries in Hispanic children in the study population.
