How sublingual buprenorphine may affect mouth and dental health

Understanding the Association between Sublingual Buprenorphine and Oral Health Outcomes

NIH-funded research University of Kentucky · NIH-11354406

This project will compare saliva, mouth bacteria, and dental health in adults with opioid use disorder who take sublingual buprenorphine to learn whether the medicine is linked to more oral disease.

What this research studies

If you join, the team will follow your dental health over time with regular mouth exams and questionnaires about oral hygiene and behaviors. They will collect saliva and oral swabs to measure salivary flow, pH, and inflammatory markers and will use 16S rRNA sequencing to profile mouth bacteria. The study will compare people taking sublingual buprenorphine to control groups while accounting for smoking, diet, and other lifestyle factors. Results will show whether changes in saliva or the oral microbiome explain any increased dental disease.

Who could benefit from this research

Good fit: Adults with opioid use disorder who are currently taking or starting sublingual buprenorphine and who can attend clinic visits are the best fit for this study.

Not a fit: People not using sublingual buprenorphine, those on other forms of MOUD exclusively, or those unable to attend follow-up visits are unlikely to benefit directly from joining.

Why it matters

Potential benefit: If successful, the work could identify preventable causes of dental problems in people using sublingual buprenorphine and guide steps (like extra dental care) to reduce harm.

How similar studies have performed: Previous evidence linking sublingual buprenorphine to oral disease comes mostly from case reports and adverse-event summaries, so longitudinal microbiome-focused work like this is relatively novel.
