INDICATE-2

Introducing diabetes checks in dental settings: a study to explore whether dental settings can be used to identify new cases of prediabetes and diabetes

The INDICATE-2 research study, led by the University of Birmingham, aims to identify how many patients visiting high street dental practices may be at risk of, or unknowingly living with, type 2 diabetes or non-diabetic hyperglycaemia (NDH).

What's the study about?

We are working with 50 high street dental practices across the UK to recruit up to 10,000 adult patients. Each participant will:

  • Complete a diabetes risk questionnaire
  • Provide a finger-prick blood sample (HbA1c test)
  • Be invited to provide a saliva sample for future research

If a patient’s HbA1c result indicates they are at risk of type 2 diabetes, they will be referred to their GP for further medical assessment and care.

Why Dental Practices?

Dental teams are uniquely positioned to support early detection of diabetes. Unlike GP visits, dental check-ups are routine—even when patients feel well. Dentists already advise on lifestyle factors like diet, smoking, and weight management, which are also key risk factors for type 2 diabetes.

Importantly, there is a two-way relationship between diabetes and periodontitis (gum disease):

  • People with diabetes are more likely to develop gum disease
  • Gum disease can worsen blood sugar control and increase the risk of developing type 2 diabetes

This makes the dental setting an ideal place to identify patients at risk and support early intervention.

What will the study achieve?

This study will:

  • Validate two diabetes risk tools—the Diabetes Risk assessment in Dentistry Score (DDS) and the Leicester Risk Assessment (LRA)—in a diverse UK dental population
  • Estimate the prevalence of undiagnosed NDH and type 2 diabetes in a multi-ethnic, pan-socioeconomic population
  • Track the medical follow-up of patients identified as high-risk in dental settings

Saliva samples will be biobanked and, subject to additional funding, analysed to test patented biomarker panels for non-invasive, point-of-care diabetes and periodontal diagnostics.

Aligned with National Policy

This research supports the NHS England Commissioning Standard on Dental Care for People with Diabetes, which encourages dental teams to engage in risk assessment/early case detection of undiagnosed NDH/diabetes and to refer onwards for formal diagnosis and management

Who's behind the study?

This study is led by the University of Birmingham and is funded by Haleon and the National Institute for Health and Care Research (NIHR).

The Bigger Picture

Dental teams could soon detect early signs of undiagnosed Type-2 diabetes as part of routine appointments.

This research could help shape new national care pathways — integrating dental and medical care to better manage both diabetes and gum disease. It’s a step toward more holistic, preventative healthcare.
