Generating Evidence that Matters in Dentistry

Welcome to the South Texas Oral Health Network (STOHN)!  

STOHN is a practice-based research network (PBRN) dedicated to developing a research infrastructure for generating practical and timely information to enhance the quality and efficacy of oral health care. STOHN members are practicing dentists and dental hygienists in South Texas who help to develop and implement dental research where it really matters – in their practices. Below is a description of some STOHN studies currently enrolling members:


STOHN Autism Tooth Fairy Study: In collaboration with Dr. Raymond Palmer and his team from the Department of Family and Community Medicine, STOHN participated in the Autism Tooth Fairy Study. STOHN collected healthy deciduous teeth to be analyzed for potential biomarkers that impact neurological development. The STOHN study team developed and incorporated an educational environmental health component to inform dental healthcare providers of recent autism research and introduce environmentally induced illnesses. 

What is the Fuss about Floss? An Issue of Critical Thinking: In May 2017 STOHN launched its first study for hygienists only. This anonymous online survey focused on evaluating the knowledge, awareness, and attitudes of practicing dental hygienists and dental hygiene faculty in response to the recent Associated Press (AP) report "Medical Benefits of Dental Floss Unproven."  This report focuses on the lack of evidence supporting flossing as part of a daily oral hygiene routine. 

Assessing Patients' Knowledge and Awareness of Xerostomia and its Prevalence in South Texas: A Card Study We are interested in testing patient’s recognition and awareness of Xerostomia, also known as dry mouth. Xerostomia affects millions of people in the U.S. with an estimated prevalence from 5.5% to 46%, affecting the geriatric population most prominently. Contact us to find out more detail about the study and how to become involved.
