OBJECTIVES: To determine whether there is a socioeconomic status (SES) disparity in caries experience (i.e., DMFT) in an adolescent sample from Pennsylvania and to determine whether differences in oral hygiene behaviors and preventive interventions account for this disparity. METHODS: A cross-sectional clinical assessment was conducted on a representative sample of 9th grade and 11th grade students across Pennsylvania. These students also completed a brief questionnaire regarding their oral hygiene behaviors. From this group of students, a random subsample of 530 parents completed a questionnaire assessing SES, fluoride exposure, and recency of receipt of dental services. DMFT was examined at two thresholds of severity: simple prevalence (DMFT > 0) and severe caries (DMFT > 3). RESULTS: Using structural equation modeling, we found that lower SES was associated with higher prevalence of DMFT and higher prevalence of severe caries. Although lower SES was associated with lower rates of brushing, less use of sealants, and less recent receipt of dental services, these oral health behaviors and preventive interventions did not account for the disparities in DMFT defined by SES. CONCLUSIONS: There is an SES gradient in caries experience in adolescents in Pennsylvania. Disparities in caries experience, however, cannot be accounted for by SES-associated differences in brushing, flossing, sealant use, fluoride exposure, or recency of use of dental services. To facilitate the design of preventive interventions, future research should determine the pathways through which SES-associated disparities occur. [ABSTRACT FROM AUTHOR]

Objective: The aim of this study was to characterize the association between clinical and psychosocial factors as they related to perceptions by parents and adolescents to the adolescent's oral health status and treatment need. Additionally, the degree to which adolescent's and parent's perceptions of oral health and treatment need were related was examined. Methods: Data from the Pennsylvania oral health needs assessment for 530 parent-adolescent pairs were used to address the objectives of this study. Comparisons between clinical oral health measures, psychosocial factors, and the parent- and adolescent-reported perceptions of the adolescent's oral health status were made using descriptive and inferential statistics, including exploratory factor analysis and path analysis. Results: Parents and adolescents exhibited only modest concordance on ratings of the adolescent's oral health status and need for dental treatment. Furthermore, parents tended to rate their adolescent's oral health status as better than did the adolescent. The results of the path analysis showed that adolescents based their ratings of oral health status more on oral symptoms, while parents rated their adolescent's oral health more on esthetic or psychosocial factors. Conclusions: Adolescents and parents based their perceptions of oral health status and treatment need on different underlying factors. Additionally, adolescents' perceptions of their oral health status and treatment needs did not appear to be communicated to their parents. [ABSTRACT FROM AUTHOR]

OBJECTIVES: The oral health of a large cohort of adult insulin-dependent diabetic patients (Type 1), diagnosed 24 years previously with juvenile onset, was comprehensively assessed. This paper describes the prevalence of coronal and root caries in this adult Type 1 diabetic population and evaluates demographic, dietary, behavioral, physiologic, salivary and medical variables associated with decayed and filled surfaces in the crown (DFS) or root (RDFS). METHODS: Type 1 diabetes mellitus subjects participating in this oral health evaluation had been monitored for 6-8 years as participants in the University of Pittsburgh, Department of Epidemiology, longitudinal study of medical complications associated with diabetes. Four hundred and six diabetic subjects received a comprehensive oral health examination during one of their regularly scheduled medical visits. Oral assessments included coronal and root caries, missing teeth, edentulism, periodontal status, soft tissue pathologies, salivary function and health behaviors. Sixteen diabetic subjects and one control subject were edentulous. Coronal and root caries data from the remaining 390 dentate diabetic subjects were compared with 202 dentate nondiabetic control subjects. RESULTS: The adult Type 1 diabetic subjects were not found to have significantly higher DFS rates as compared with our control subjects or published age-adjusted NHANES III findings. Both control and diabetic subjects had low decayed to filled tooth surface ratios. A linear regression model evaluated possible associations with coronal decayed and filled tooth surfaces (DFS) within the diabetic population. Significant factors included older age, women, fewer missing teeth, more frequent use of dental floss, more frequent visits to the dentist during the last 12 months, and diabetic nephropathy. The prevalence of RDFS was higher in the diabetic subjects as compared to recruited control subjects. Neither dietary behaviors nor glycemic control were found to contribute to coronal or root caries. CONCLUSIONS: Factors associated with presence of coronal and root caries and fillings are discussed. Possible causes and implications for the association between DFS and diabetic nephropathy are provided. [ABSTRACT FROM AUTHOR]
