Texting your way to better diabetes control? new trial tests SMS gum care reminders.
NCT ID NCT07165171
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study tests whether sending SMS reminders and advice to people with type 2 diabetes and gum disease can improve their blood sugar control over two years. 516 adults who recently completed gum disease treatment will be split into two groups: one gets standard follow-up, the other gets text messages with medical info, questions, and appointment reminders. The main goal is to see if the SMS group has lower HbA1c levels, a key measure of blood sugar control.
