To assess the dental needs of Bexar County children ages 0-18 who are uninsured or are Medicaid or Texas Children's Health Insurance Program (CHIP) recipients.Dental clinics that treat children ages 0-18 and act as the safety net were identified in order to assess their capacity to treat children.

The dental needs of the community are 227,124 patient encounters per year.The results of the study suggest that the Bexar County is not prepared to treat the dental needs of the underserved children in San Antonio.
