The Latest Facts & Findings

Our research has focused on understanding the implications of diabetes in oral health care and the role of oral health in diabetes.

37 million

people in the U.S. are thought to have diabetes. In Bexar County, which includes San Antonio, almost 14% of the population has been diagnosed with diabetes.

$5.7 million

in NIH support goes toward clinical research understanding the relationship of diabetes and oral health in San Antonio.

"Being a part of these research projects allows me to enjoy the look of delight on our diabetic patients’ faces for treatment that they may not otherwise receive. This is the blending of research and clinical care."
