This Statistical Brief presents nationwide data from the Healthcare Cost and Utilization Project (HCUP) on ED visits for treatment of dental-related conditions in 2009. Patient characteristics of ED visits for dental care are described, and dental visits that resulted in a hospital admission are compared to treat-and-release ED visits. Patient demographics (sex, age, patient residence, and community income level), primary expected payer, patient-to-dentist ratios, and the most common dental conditions are described. Figures highlight differences that were statistically significant. All differences between subgroup estimates noted in the text are statistically significant at the 0.05 probability level or better.
