Abstract

Background

Untreated dental caries afflicts almost one third of school-aged children in the United States and many of them are from disadvantaged families. This cross-sectional study was undertaken to investigate the prevalence of untreated caries in north central Kentucky, USA and to examine the relationships between the available demographic variables and untreated childhood caries as reported on the forms from the Smile Kentucky! program.

Methods

During the fall of 2008, caries status was assessed during the visual oral screening examination component of “SmileKentucky!”– a model of the American Dental Association’s Give Kids A Smile program. Parents had completed brief surveys concerning 3,488 elementary school children aged 5 to 13 years who participated in the program. A secondary analysis was conducted using univariate, bivariate and multivariate statistical methods.

Results

Untreated caries was reported in 33% of children. Bivariate and logistic regression analyses found that the most significant risk factors for having untreated caries were living in the metropolitan Louisville, Kentucky area, not having had a dental visit in the previous 3 years and not having any form of dental insurance.

Conclusions

Untreated caries in elementary school children is prevalent in north-central Kentucky despite efforts to improve access to care. The results suggest that additional family and community preventive initiatives are needed to reduce the development of childhood caries in this area of the United States.
