    Abstract:
    OBJECTIVES: This cross-sectional study was designed to determine the caries status and provide a general evaluation of the level of dental treatment need of Pennsylvania public school children in grades 1, 3, 9, and 11 on a statewide and regional basis. METHODS: Between September 1998 and May 2000, caries status and treatment need were assessed using a school-based dental examination, performed on a representative sample (n=6,040) of public school children in grades 1, 3, 9, and 11 (age range=6 to 21 years). Children's caries status in the primary and permanent dentition was assessed. Need for treatment was scored on a three-level categorical scale--no treatment need identified, routine treatment need, and urgent treatment need--and was based on the presence and severity of caries and other oral conditions. Population estimates of the prevalence of untreated dental caries, DMFT and dft scores, and treatment need were calculated by grade and geographically, using the six Pennsylvania health districts and the cities of Pittsburgh and Philadelphia. The inequality of caries distribution in the population was assessed for both permanent and primary caries using Lorenz curves and Gini coefficients. RESULTS: Dental caries has remained highly prevalent among Pennsylvania's public school children. Caries levels varied considerably by health districts and city. Urgent treatment needs were significant and also varied by health district and city. CONCLUSIONS: Dental caries remains the most prevalent disease affecting Pennsylvania's schoolchildren. Caries status varies significantly by region of the state, suggesting that environmental, social, and demographic contextual factors may be important determinants of disease prevalence.
